Un essai clinique randomisé en groupes parallèles portant sur 51 hommes (23,6 ± 3,5 ans ; 83,5 ± 7,8 kg ; 28,0 ± 1,9 kg/m2) physiquement inactifs (c.-à-d. 6 mois) et obèses abdominalement (tour de taille ≥90 cm) ou ayant un indice de masse corporelle, un IMC ≥25 et ≤ 30 kg/m2 ont été randomisés selon les quatre protocoles d'exercice suivants : exercice de haute intensité (intervalles de 4 × 4 min à 85-95 % de la fréquence cardiaque maximale [HRmax] entrecoupés de 4 min de récupération à 75-85 % HRmax) (n = 14), entraînement en résistance (12-15 répétitions par série, à 50-70 % d'une répétition maximale avec 60 s de récupération) (n = 12), exercice combiné de haute intensité et de résistance (n = 13), ou contrôle sans exercice (n = 12). Les taux plasmatiques de neurotrophine-3 (NT-3), de neurotrophine-4 (également connue sous le nom de neurotrophine 4/5 ; NT-4 ou NT-4/5) et de facteur neurotrophique dérivé du cerveau (BDNF) ont été déterminés avant (avant l'exercice) et 1 min après l'exercice pour chaque session de protocole. L'entraînement en résistance a induit des augmentations significatives du NT-3 (+39,6 ng/mL [IC à 95 % : 2,5-76,6 ; p = 0,004] et du NT-4/5 (+1,3 ng/mL [IC à 95 % : 0,3-2,3 ; p = 0,014]), respectivement. De plus, l'entraînement combiné entraîne des effets favorables sur le BDNF (+22,0, IC à 95 %, 2,6-41,5 ; p = 0,029) et le NT-3 (+32,9 ng/mL [IC à 95 %, 12,3-53,4 ; p = 0,004]), respectivement. L'analyse de régression a révélé une relation positive significative entre les changements dans les niveaux de BDNF et les changements dans les niveaux de NT-4/5 de la ligne de base à immédiatement après l'exercice dans le groupe d'entraînement combiné (R2 = 0,345, p = 0,034) mais pas dans les autres groupes d'intervention. Les résultats indiquent que l'entraînement en résistance aiguë et l'exercice combiné augmentent les facteurs neurotrophiques chez les adultes en surpoids physiquement inactifs. D'autres études sont nécessaires pour déterminer l'importance biologique des changements dans les réponses neurotrophiques chez les hommes en surpoids et les effets chroniques de ces protocoles d'exercice.ClinicalTrials.gov, NCT02915913 (Date : 22 septembre 2016). El propósito de este estudio fue comparar la respuesta del factor neurotrófico después de una sesión de ejercicio de alta intensidad, entrenamiento de resistencia o ambos en una cohorte de adultos con sobrepeso físicamente inactivos de 18 a 30 años de edad. Un ensayo clínico aleatorizado de grupos paralelos de 51 hombres (23.6 ± 3.5 años; 83.5 ± 7.8 kg; 28.0 ± 1.9 kg/m2) que son físicamente inactivos (es decir, 6 meses) y son abdominalmente obesos (circunferencia de la cintura ≥90 cm) o tienen un índice de masa corporal, IMC ≥25 y ≤ 30 kg/m2 fueron asignados al azar a los siguientes cuatro protocolos de ejercicio: ejercicio de alta intensidad (intervalos de 4 × 4 min a 85-95% de frecuencia cardíaca máxima [HRmax] intercalados con 4 min de recuperación a 75-85% HRmax) (n = 14), entrenamiento de resistencia (12-15 repeticiones por serie, al 50-70% de una repetición máxima con 60 s de recuperación) (n = 12), ejercicio combinado de alta intensidad y resistencia (n = 13), o control sin ejercicio (n = 12). Los niveles plasmáticos de neurotrofina-3 (NT-3), neurotrofina-4 (también conocida como neurotrofina 4/5; NT-4 o NT-4/5) y factor neurotrófico derivado del cerebro (BDNF) se determinaron antes (antes del ejercicio) y 1 minuto después del ejercicio para cada sesión de protocolo. El entrenamiento de resistencia indujo aumentos significativos en NT-3 (+39.6 ng/mL [IC 95%, 2.5-76.6; p = 0.004] y NT-4/5 (+1.3 ng/mL [IC 95%, 0.3-2.3; p = 0.014]), respectivamente. Además, el entrenamiento combinado produce efectos favorables en BDNF (+22.0, IC del 95%, 2.6-41.5; p = 0.029) y NT-3 (+32.9 ng/mL [IC del 95%, 12.3-53.4; p = 0.004]), respectivamente. El análisis de regresión reveló una relación positiva significativa entre los cambios en los niveles de BDNF y los cambios en los niveles de NT-4/5 desde el inicio hasta el post-ejercicio inmediato en el grupo de entrenamiento combinado (R2 = 0.345, p = 0.034) pero no en los otros grupos de intervención. Los hallazgos indican que el entrenamiento de resistencia agudo y el ejercicio combinado aumentan los factores neurotróficos en adultos con sobrepeso físicamente inactivos. Se requieren más estudios para determinar la importancia biológica de los cambios en las respuestas neurotróficas en hombres con sobrepeso y los efectos crónicos de estos protocolos de ejercicio.ClinicalTrials.gov, NCT02915913 (Fecha: 22 de septiembre de 2016). كان الغرض من هذه الدراسة هو مقارنة استجابة العامل العصبي بعد جلسة واحدة من التمارين عالية الكثافة أو تدريب المقاومة أو كليهما في مجموعة من البالغين الذين يعانون من زيادة الوزن غير النشطين جسديًا والذين تتراوح أعمارهم بين 18 و 30 عامًا. تجربة سريرية عشوائية لمجموعة متوازية من 51 رجلاً (23.6 ± 3.5 سنة ؛ 83.5 ± 7.8 كجم ؛ 28.0 ± 1.9 كجم/م 2) غير نشطين جسديًا (أي أقل من 150 دقيقة من التمارين المعتدلة الكثافة في الأسبوع أو درجة IPAQ أقل من 600 دقيقة/أسبوع لمدة >6 أشهر) وإما يعانون من السمنة المفرطة في البطن (محيط الخصر ≥90 سم) أو لديهم مؤشر كتلة الجسم، مؤشر كتلة الجسم ≥25 و ≤ 30 كجم/م 2 تم توزيعهم عشوائيًا على بروتوكولات التمرين الأربعة التالية: تمرين عالي الكثافة (4 × 4 دقائق على فترات 85-95 ٪ كحد أقصى لمعدل ضربات القلب [HRmax] يتخللها 4 دقائق من التعافي عند 75-85 ٪ HRmax) (n = 14)، تدريب المقاومة (12-15 تكرار لكل مجموعة، عند 50-70 ٪ من الحد الأقصى للتكرار الواحد مع 60 ثانية من التعافي) (n = 12)، تمرين عالي الكثافة والمقاومة مجتمعين (n = 13)، أو التحكم غير الممارس (n = 12). تم تحديد مستويات البلازما من neurotrophin -3 (NT -3)، neurotrophin -4 (المعروف أيضًا باسم neurotrophin 4/5 ؛ NT -4 أو NT -4/5)، والعامل العصبي المشتق من الدماغ (BDNF) قبل (التمرين المسبق) ودقيقة واحدة بعد التمرين لكل جلسة بروتوكول. أدى تدريب المقاومة إلى زيادات كبيرة في NT -3 (+39.6 نانوغرام/مل [95 ٪ CI، 2.5-76.6 ؛ p = 0.004]، و NT -4/5 (+1.3 نانوغرام/مل [95 ٪ CI، 0.3-2.3 ؛ p = 0.014])، على التوالي. بالإضافة إلى ذلك، يؤدي التدريب المشترك إلى تأثيرات مواتية على BDNF (+22.0، 95 ٪ CI، 2.6-41.5 ؛ p = 0.029) و NT -3 (+32.9 نانوغرام/مل [95 ٪ CI، 12.3-53.4 ؛ p = 0.004])، على التوالي. كشف تحليل الانحدار عن وجود علاقة إيجابية كبيرة بين التغيرات في مستويات BDNF والتغيرات في مستويات NT -4/5 من خط الأساس إلى ما بعد التمرين مباشرة في مجموعة التدريب المشتركة (R2 = 0.345، p = 0.034) ولكن ليس مجموعات التدخل الأخرى. تشير النتائج إلى أن التدريب على المقاومة الحادة والتمارين المشتركة تزيد من عوامل التغذية العصبية لدى البالغين الذين يعانون من زيادة الوزن غير النشطين جسديًا. هناك حاجة إلى مزيد من الدراسات لتحديد الأهمية البيولوجية للتغيرات في الاستجابات العصبية لدى الرجال الذين يعانون من زيادة الوزن والآثار المزمنة لبروتوكولات التمرين هذه .ClinicalTrials.gov, NCT02915913 (التاريخ: 22 سبتمبر 2016). The purpose of this study was to compare the neurotrophic factor response following one session of high-intensity exercise, resistance training or both in a cohort of physically inactive overweight adults aged 18-30 years old. A randomized, parallel-group clinical trial of 51 men (23.6 ± 3.5 years; 83.5 ± 7.8 kg; 28.0 ± 1.9 kg/m2) who are physically inactive (i.e., 6 months) and are either abdominally obese (waist circumference ≥90 cm) or have a body mass index, BMI ≥25 and ≤ 30 kg/m2 were randomized to the following four exercise protocols: high-intensity exercise (4 × 4 min intervals at 85-95% maximum heart rate [HRmax] interspersed with 4 min of recovery at 75-85% HRmax) (n = 14), resistance training (12-15 repetitions per set, at 50-70% of one repetition maximum with 60 s of recovery) (n = 12), combined high-intensity and resistance exercise (n = 13), or non-exercising control (n = 12). The plasma levels of neurotrophin-3 (NT-3), neurotrophin-4 (also known as neurotrophin 4/5; NT-4 or NT-4/5), and brain-derived neurotrophic factor (BDNF) were determined before (pre-exercise) and 1-min post-exercise for each protocol session. Resistance training induced significant increases in NT-3 (+39.6 ng/mL [95% CI, 2.5-76.6; p = 0.004], and NT-4/5 (+1.3 ng/mL [95% CI, 0.3-2.3; p = 0.014]), respectively. Additionally, combined training results in favorable effects on BDNF (+22.0, 95% CI, 2.6-41.5; p = 0.029) and NT-3 (+32.9 ng/mL [95% CI, 12.3-53.4; p = 0.004]), respectively. The regression analysis revealed a significant positive relationship between changes in BDNF levels and changes in NT-4/5 levels from baseline to immediate post-exercise in the combined training group (R2 = 0.345, p = 0.034) but not the other intervention groups. The findings indicate that acute resistance training and combined exercise increase neurotrophic factors in physically inactive overweight adults. Further studies are required to determine the biological importance of changes in neurotrophic responses in overweight men and chronic effects of these exercise protocols.ClinicalTrials.gov, NCT02915913 (Date: September 22, 2016).

Velasco-Orjuela; Antonio García-Hermoso; Emilio Villa-González; Irene Esteban-Cornejo; María Correa-Rodríguez; Robinson Ramírez-Vélez;There is currently a consensus about the positive effects of physical exercise on cognition. However, the exercise intensity-dependent effect on executive function remains unclear. Thus, the aim of this study was to compare the acute effects of high-intensity aerobic interval training (HIIT), progressive resistance training (PRT), or combined training (PRT + HIIT) on executive function indicators in overweight inactive adult men (aged 18-30 years old). The participants were screened and excluded for medical conditions known to impact cognitive functioning, which was measured with the Montreal Cognitive Assessment (MoCA) screening cognitive test. A randomised, parallel-group clinical trial was conducted among 36 adults who were randomly assigned to a HIIT (n = 12), PRT (n = 7), PRT + HIIT (n = 7), or control group (n = 10) until the energy expenditure of 400-500 kcal. Cognitive inhibition and attention capacity were examined using the Stroop test and d2 test of attention, respectively, and were obtained pre-exercise for baseline measurement and 1 min post-exercise for each exercise training modality. Cognitive inhibition measured by the Stroop test was improved after the HIIT protocol for the domains of reading by +5.89 (η2 = 0.33), colour naming +9.0 (η2 = 0.60), interference +10.1 (η2 = 0.39), and index interference +6.0 (η2 = 0.20). Additionally, the PRT + HIIT group had an increase for the reading condition of +7.1 (η2 = 0.40), colour naming +7.5 (η2 = 0.80), and interference +5.8 (η2 = 0.39). In regard to attentional capacity, the HIIT group elicited small to medium improvements in the concentration level domain of +21.7 (η2 = 0.44), total performance domain +56.6 (η2 = 0.50), and consistency domain -3.0 (η2 = 0.27). These results were similar in the PRT and PRT + HIIT groups in the concentration level and items-processed domains (P < 0.05). In conclusion, acute HIIT and PRT + HIIT sessions reported important effect sizes than PRT alone for cognitive inhibition and attention capacity. Taken together, the results suggest that even short-term exercise interventions can enhance overweight adults' executive functions.

It is well known that physical exercise modifies plasma levels of testosterone and cortisol. However, the effect of high-intensity interval training (HIIT) on the plasma hormone levels is controversial. The aim of the study was to compare the effects of HIIT exercise or submaximal continuous aerobic exercise on circulating testosterone and cortisol levels in active male collegiate students. Methods: Thirteen moderately-active young adult males (20.2 (SD 2.1) years old) completed a HIIT (20 min of 15 s intervals of running at 110% of maximum oxygen consumption interspersed with 15 s of active rest at 40% of maximum oxygen consumption) and a continuous aerobic exercise (AEE) 20 min at 70–75% of maximum oxygen consumption. The mean total workload of both protocols was the same for each exercise session. Blood samples were collected pre-session (rest), immediately after the session (0 h), and 12 h post-session (12 h). Results: Both exercise protocols, similarly increased plasma levels of free testosterone immediately post-exertion (p < 0.05 AEE and p < 0.01 HIIT). No differences were observed between the conditions in the concentration of testosterone at 12 h. Cortisol level and Testosterone/Cortisol (T/C) ratio remained constant for all measurements, regardless of the type of exercise performed. Conclusion: The testosterone concentrations rose significantly post intervention in both HIIT and AEE condition, but 12 h post intervention there was no difference between conditions, decreasing to baseline (pre-intervention). The T/C ratio decreased significantly (below baseline) only in the HIIT condition 12 h post intervention.

Aunque existe evidencia consistente de los efectos positivos de la actividad física en varios aspectos de la salud, la mayoría de los adolescentes en Colombia son sedentarios. Por lo tanto, es importante implementar estrategias que generen cambios en el estilo de vida. El estudio HEPAFIT tiene como objetivo examinar si un programa de ejercicio de 6 meses tiene beneficios para el contenido de grasa hepática y los resultados de salud cardiovascular entre adolescentes con sobrepeso/obesidad de Bogotá, Colombia. En conjunto, se incluirán 100 adolescentes sedentarios con sobrepeso/obesidad (de 11 a 17 años) que asisten a dos escuelas públicas en Bogotá, Colombia, en un ensayo controlado aleatorizado de grupos paralelos. Los adolescentes serán asignados aleatoriamente a un grupo de intervención siguiendo uno de los cuatro planes de estudio: (1) el plan de estudios estándar de educación física (60 minutos por semana de actividad física, n = 25) a una intensidad baja a moderada; (2) un plan de estudios de educación física de alta intensidad (HIPE, n = 25), que consiste en juegos de resistencia y resistencia y actividades no competitivas, como correr, gymkhanas, levantar, empujar, luchar o acarrear, durante sesiones de 60 minutos, tres veces por semana, con un objetivo de gasto de energía de 300 a 500 kcal/sesión a una frecuencia cardíaca máxima del 75-85% (HRmax); (3) un plan de estudios de educación física de intensidad baja a moderada (LIPE, n = 25) que consiste en juegos de resistencia y resistencia y actividades no competitivas (por ejemplo, perseguir, correr, driblear o saltar) durante sesiones de 60 minutos, tres veces por semana con un objetivo de gasto de energía de 300 kcal/sesión al 55-75% HRmax; y (4) un plan de estudios combinado de HIPE y LIPE (n = 25). La HIPE, LIPE y las intervenciones combinadas se realizaron además del plan de estudios estándar de educación física. El resultado primario para la efectividad es el contenido de grasa hepática, medido por el parámetro de atenuación controlada 1 semana después del final del programa de intervención. El enfoque traslacional puede ser adecuado para recopilar nueva información en un entorno escolar sobre los posibles efectos de las intervenciones de actividad física para reducir el contenido de grasa hepática y mejorar los perfiles metabólicos y la salud cardiometabólica de los adolescentes con sobrepeso/obesos. Esto puede conducir a un uso más eficiente de los recursos de educación física escolar.ClinicalTrials.gov, NCT02753231 . Inscrita el 21 de abril de 2016. Une proportion considérable de jeunes contemporains présentent un risque élevé de troubles liés à l'obésité tels que les maladies cardiovasculaires, le syndrome métabolique ou la stéatose hépatique non alcoolique (SHNA). Bien qu'il existe des preuves constantes des effets positifs de l'activité physique sur plusieurs aspects de la santé, la plupart des adolescents en Colombie sont sédentaires. Il est donc important de mettre en œuvre des stratégies qui génèrent des changements de mode de vie. L'étude HEPAFIT vise à examiner si un programme d'exercice de 6 mois présente des avantages pour la teneur en graisse hépatique et les résultats en matière de santé cardiovasculaire chez les adolescents en surpoids/obèses de Bogotá, en Colombie. Au total, 100 cents adolescents sédentaires en surpoids/obèses (âgés de 11 à 17 ans) fréquentant deux écoles publiques de Bogotá, en Colombie, seront inclus dans un essai contrôlé randomisé en groupes parallèles. Les adolescents seront répartis au hasard dans un groupe d'intervention selon l'un des quatre programmes suivants : (1) le programme d'éducation physique standard (60 minutes par semaine d'activité physique, n = 25) à une intensité faible à modérée ; (2) un programme d'éducation physique de haute intensité (HIPE, n = 25), composé de jeux d'endurance et de résistance et d'activités non compétitives, telles que la course, les gymkhanas, le levage, la poussée, la lutte ou le halage, pour des sessions de 60 minutes, trois fois par semaine, avec un objectif de dépense énergétique de 300 à 500 kcal/session à une fréquence cardiaque maximale de 75 à 85 % (HRmax) ; (3) un programme d'éducation physique d'intensité faible à modérée (LIPE, n = 25) composé de jeux d'endurance et de résistance et d'activités non compétitives (par exemple, chasser, sprinter, dribbler ou sauter) pour des sessions de 60 minutes, trois fois par semaine avec un objectif de dépense énergétique de 300 kcal/session à 55-75 % HRmax ; et (4) un programme combiné HIPE et LIPE (n = 25). Les interventions HIPE, LIPE et combinées ont été réalisées en plus du programme d'éducation physique standard. Le principal critère d'évaluation de l'efficacité est la teneur en graisse du foie, mesurée par le paramètre d'atténuation contrôlée 1 semaine après la fin du programme d'intervention. L'accent mis sur la traduction peut convenir à la collecte de nouvelles informations en milieu scolaire sur les effets possibles des interventions d'activité physique pour réduire la teneur en graisse du foie et améliorer les profils métaboliques et la santé cardiométabolique des adolescents en surpoids/obèses. Cela peut conduire à une utilisation plus efficace des ressources scolaires en matière d'éducation physique.ClinicalTrials.gov, NCT02753231 . Enregistré le 21 avril 2016. A considerable proportion of contemporary youth have a high risk of obesity-related disorders such as cardiovascular disease, metabolic syndrome, or non-alcoholic fatty liver disease (NAFLD). Although there is consistent evidence for the positive effects of physical activity on several health aspects, most adolescents in Colombia are sedentary. It is, therefore, important to implement strategies that generate changes in lifestyle. The HEPAFIT study aims to examine whether a 6-month exercise program has benefits for hepatic fat content and cardiovascular health outcomes among overweight/obese adolescents from Bogotá, Colombia.Altogether, 100 hundred overweight/obese, sedentary adolescents (aged 11-17 years) attending two public schools in Bogotá, Colombia, will be included in a parallel-group randomized controlled trial. Adolescents will be randomly assigned to an intervention group following one of four curricula: (1) the standard physical education curriculum (60 min per week of physical activity, n = 25) at low-to-moderate intensity; (2) a high-intensity physical education curriculum (HIPE, n = 25), consisting of endurance and resistance games and non-competitive activities, such as running, gymkhanas, lifting, pushing, wrestling, or hauling, for 60-min sessions, three times per week, with an energy expenditure goal of 300 to 500 kcal/session at 75-85% maximum heart rate (HRmax); (3) a low-to-moderate intensity physical education curriculum (LIPE, n = 25) consisting of endurance and resistance games and non-competitive activities (e.g., chasing, sprinting, dribbling, or hopping) for 60-min sessions, three times per week with an energy expenditure goal of 300 kcal/session at 55-75% HRmax; and (4) a combined HIPE and LIPE curriculum (n = 25). The HIPE, LIPE, and combined interventions were performed in addition to the standard physical education curriculum. The primary outcome for effectiveness is liver fat content, as measured by the controlled attenuation parameter 1 week after the end of the intervention program.The translational focus may be suitable for collecting new information in a school setting on the possible effects of physical activity interventions to reduce liver fat content and to improve metabolic profiles and the cardiometabolic health of overweight/obese adolescents. This may lead to the more efficient use of school physical education resources.ClinicalTrials.gov, NCT02753231 .

Background: Studies were performed in order to determine the existing relationship between body composition and both physical activity (PA) levels and food habits. Nevertheless, no study has yet examined if the association between adiposity and PA in children is moderated by adherence to the Mediterranean diet (MD). Methods: the cross-sectional and associative analysis involved a total of 370 children (55.1% boys) aged 6–13, from six different schools from the Murcia region of Spain. Results: The different values of moderator [adherence to the MD expressed as a Mediterranean Diet Quality Index (KIDMED) score] are shown by the slope and the different areas of significance. The first area was shown below ≤3.8, indicating that the unfavorable influence of excess of adiposity on PA could be intensified for children in this area. The second area was a significant positive area was shown above ≥9.3, expressing that the unfavorable influence of adiposity could be reduced for those who were above this estimation point. Conclusion: Our findings reveal that the adverse effects of excess adiposity on PA can be moderated by adherence to the MD among schoolchildren.

However, its effects on explosive and endurance performance at high altitude had not been studied. Therefore, the aim of this study was to determine the effects of a sea level short-term (i.e., 4-week) plyometric training program on explosive and endurance performance at sea level and at high altitude (i.e., 3,270 m above sea level). Participants were randomly assigned to a control group (n = 12) and a plyometric training group (n = 11). Neuromuscular (reactive strength index - RSI) and endurance (2-km time-trial; running economy [RE]; maximal oxygen uptake - VO2max) measurements were performed at sea level before, at sea level after intervention (SL +4 week), and at high altitude 24-h post SL +4 week. The ANOVA revealed that at SL +4 week the VO2max was not significantly changed in any group, although RE, RSI and 2-km time trial were significantly (p < 0.05) improved in the plyometric training group. After training, when both groups were exposed to high altitude, participants from the plyometric training group showed a greater RSI (p < 0.05) and were able to maintain their 2-km time trial (11.3 ± 0.5 min vs. 10.7 ± 0.6 min) compared to their pre-training sea level performance. In contrast, the control group showed no improvement in RSI, with a worse 2-km time trial performance (10.3 ± 0.8 min vs. 9.02 ± 0.64 min; p < 0.05; ES = 0.13). Moreover, after training, both at sea level and at high altitude the plyometric training group demonstrated a greater (p < 0.05) RSI and 2-km time trial performance compared to the control group. The oxygen saturation was significantly decreased after acute exposure to high altitude in the two groups (p < 0.05). These results confirm the beneficial effects of sea level short-term plyometric training on explosive and endurance performance at sea level. Moreover, current results indicates that plyometric training may also be of value for endurance athletes performing after an acute exposure to high altitude.

However, given that the DXA technique is impractical for routine field use, there is a need to investigate other methods that can accurately determine BF%. We studied the accuracy of bioelectrical impedance analysis (BIA) technology, including foot-to-foot and hand-to-foot impedance, and Slaughter skinfold-thickness equations in the measurement of BF%, compared with DXA, in a population of Latin American children and adolescents with an excess of adiposity. A total of 127 children and adolescents (11–17 years of age; 70% girls) from the HEPAFIT (Exercise Training and Hepatic Metabolism in Overweight/Obese Adolescent) study were included in the present work. BF% was measured on the same day using two BIA analysers (Seca® 206, Allers Hamburg, Germany and Model Tanita® BC-418®, TANITA Corporation, Sportlife Tokyo, Japan), skinfold measurements (Slaughter equation), and DXA (Hologic Horizon DXA System®, Quirugil, Bogotá, Columbia). Agreement between measurements was analysed using t-tests, Bland–Altman plots, and Lin’s concordance correlation coefficient (ρc). There was a significant correlation between DXA and the other BF% measurement methods (r > 0.430). According to paired t-tests, in both sexes, BF% assessed by BIA analysers or Slaughter equations differ from BF% assessed by DXA (p < 0.001). The lower and upper limits of the differences compared with DXA were 6.3–22.9, 2.2–2.8, and −3.2–21.3 (95% CI) in boys and 2.3–14.8, 2.4–20.1, and 3.9–18.3 (95% CI) in girls for Seca® mBCA, Tanita® BC 420MA, and Slaughter equations, respectively. Concordance was poor between DXA and the other methods of measuring BF% (ρc < 0.5). BIA analysers and Slaughter equations underestimated BF% measurements compared to DXA, so they are not interchangeable methods for assessing BF% in Latin American children and adolescents with excess of adiposity.

Un essai clinique randomisé en groupes parallèles portant sur 51 hommes (23,6 ± 3,5 ans ; 83,5 ± 7,8 kg ; 28,0 ± 1,9 kg/m2) physiquement inactifs (c.-à-d. 6 mois) et obèses abdominalement (tour de taille ≥90 cm) ou ayant un indice de masse corporelle, un IMC ≥25 et ≤ 30 kg/m2 ont été randomisés selon les quatre protocoles d'exercice suivants : exercice de haute intensité (intervalles de 4 × 4 min à 85-95 % de la fréquence cardiaque maximale [HRmax] entrecoupés de 4 min de récupération à 75-85 % HRmax) (n = 14), entraînement en résistance (12-15 répétitions par série, à 50-70 % d'une répétition maximale avec 60 s de récupération) (n = 12), exercice combiné de haute intensité et de résistance (n = 13), ou contrôle sans exercice (n = 12). Les taux plasmatiques de neurotrophine-3 (NT-3), de neurotrophine-4 (également connue sous le nom de neurotrophine 4/5 ; NT-4 ou NT-4/5) et de facteur neurotrophique dérivé du cerveau (BDNF) ont été déterminés avant (avant l'exercice) et 1 min après l'exercice pour chaque session de protocole. L'entraînement en résistance a induit des augmentations significatives du NT-3 (+39,6 ng/mL [IC à 95 % : 2,5-76,6 ; p = 0,004] et du NT-4/5 (+1,3 ng/mL [IC à 95 % : 0,3-2,3 ; p = 0,014]), respectivement. De plus, l'entraînement combiné entraîne des effets favorables sur le BDNF (+22,0, IC à 95 %, 2,6-41,5 ; p = 0,029) et le NT-3 (+32,9 ng/mL [IC à 95 %, 12,3-53,4 ; p = 0,004]), respectivement. L'analyse de régression a révélé une relation positive significative entre les changements dans les niveaux de BDNF et les changements dans les niveaux de NT-4/5 de la ligne de base à immédiatement après l'exercice dans le groupe d'entraînement combiné (R2 = 0,345, p = 0,034) mais pas dans les autres groupes d'intervention. Les résultats indiquent que l'entraînement en résistance aiguë et l'exercice combiné augmentent les facteurs neurotrophiques chez les adultes en surpoids physiquement inactifs. D'autres études sont nécessaires pour déterminer l'importance biologique des changements dans les réponses neurotrophiques chez les hommes en surpoids et les effets chroniques de ces protocoles d'exercice.ClinicalTrials.gov, NCT02915913 (Date : 22 septembre 2016). El propósito de este estudio fue comparar la respuesta del factor neurotrófico después de una sesión de ejercicio de alta intensidad, entrenamiento de resistencia o ambos en una cohorte de adultos con sobrepeso físicamente inactivos de 18 a 30 años de edad. Un ensayo clínico aleatorizado de grupos paralelos de 51 hombres (23.6 ± 3.5 años; 83.5 ± 7.8 kg; 28.0 ± 1.9 kg/m2) que son físicamente inactivos (es decir, 6 meses) y son abdominalmente obesos (circunferencia de la cintura ≥90 cm) o tienen un índice de masa corporal, IMC ≥25 y ≤ 30 kg/m2 fueron asignados al azar a los siguientes cuatro protocolos de ejercicio: ejercicio de alta intensidad (intervalos de 4 × 4 min a 85-95% de frecuencia cardíaca máxima [HRmax] intercalados con 4 min de recuperación a 75-85% HRmax) (n = 14), entrenamiento de resistencia (12-15 repeticiones por serie, al 50-70% de una repetición máxima con 60 s de recuperación) (n = 12), ejercicio combinado de alta intensidad y resistencia (n = 13), o control sin ejercicio (n = 12). Los niveles plasmáticos de neurotrofina-3 (NT-3), neurotrofina-4 (también conocida como neurotrofina 4/5; NT-4 o NT-4/5) y factor neurotrófico derivado del cerebro (BDNF) se determinaron antes (antes del ejercicio) y 1 minuto después del ejercicio para cada sesión de protocolo. El entrenamiento de resistencia indujo aumentos significativos en NT-3 (+39.6 ng/mL [IC 95%, 2.5-76.6; p = 0.004] y NT-4/5 (+1.3 ng/mL [IC 95%, 0.3-2.3; p = 0.014]), respectivamente. Además, el entrenamiento combinado produce efectos favorables en BDNF (+22.0, IC del 95%, 2.6-41.5; p = 0.029) y NT-3 (+32.9 ng/mL [IC del 95%, 12.3-53.4; p = 0.004]), respectivamente. El análisis de regresión reveló una relación positiva significativa entre los cambios en los niveles de BDNF y los cambios en los niveles de NT-4/5 desde el inicio hasta el post-ejercicio inmediato en el grupo de entrenamiento combinado (R2 = 0.345, p = 0.034) pero no en los otros grupos de intervención. Los hallazgos indican que el entrenamiento de resistencia agudo y el ejercicio combinado aumentan los factores neurotróficos en adultos con sobrepeso físicamente inactivos. Se requieren más estudios para determinar la importancia biológica de los cambios en las respuestas neurotróficas en hombres con sobrepeso y los efectos crónicos de estos protocolos de ejercicio.ClinicalTrials.gov, NCT02915913 (Fecha: 22 de septiembre de 2016). كان الغرض من هذه الدراسة هو مقارنة استجابة العامل العصبي بعد جلسة واحدة من التمارين عالية الكثافة أو تدريب المقاومة أو كليهما في مجموعة من البالغين الذين يعانون من زيادة الوزن غير النشطين جسديًا والذين تتراوح أعمارهم بين 18 و 30 عامًا. تجربة سريرية عشوائية لمجموعة متوازية من 51 رجلاً (23.6 ± 3.5 سنة ؛ 83.5 ± 7.8 كجم ؛ 28.0 ± 1.9 كجم/م 2) غير نشطين جسديًا (أي أقل من 150 دقيقة من التمارين المعتدلة الكثافة في الأسبوع أو درجة IPAQ أقل من 600 دقيقة/أسبوع لمدة >6 أشهر) وإما يعانون من السمنة المفرطة في البطن (محيط الخصر ≥90 سم) أو لديهم مؤشر كتلة الجسم، مؤشر كتلة الجسم ≥25 و ≤ 30 كجم/م 2 تم توزيعهم عشوائيًا على بروتوكولات التمرين الأربعة التالية: تمرين عالي الكثافة (4 × 4 دقائق على فترات 85-95 ٪ كحد أقصى لمعدل ضربات القلب [HRmax] يتخللها 4 دقائق من التعافي عند 75-85 ٪ HRmax) (n = 14)، تدريب المقاومة (12-15 تكرار لكل مجموعة، عند 50-70 ٪ من الحد الأقصى للتكرار الواحد مع 60 ثانية من التعافي) (n = 12)، تمرين عالي الكثافة والمقاومة مجتمعين (n = 13)، أو التحكم غير الممارس (n = 12). تم تحديد مستويات البلازما من neurotrophin -3 (NT -3)، neurotrophin -4 (المعروف أيضًا باسم neurotrophin 4/5 ؛ NT -4 أو NT -4/5)، والعامل العصبي المشتق من الدماغ (BDNF) قبل (التمرين المسبق) ودقيقة واحدة بعد التمرين لكل جلسة بروتوكول. أدى تدريب المقاومة إلى زيادات كبيرة في NT -3 (+39.6 نانوغرام/مل [95 ٪ CI، 2.5-76.6 ؛ p = 0.004]، و NT -4/5 (+1.3 نانوغرام/مل [95 ٪ CI، 0.3-2.3 ؛ p = 0.014])، على التوالي. بالإضافة إلى ذلك، يؤدي التدريب المشترك إلى تأثيرات مواتية على BDNF (+22.0، 95 ٪ CI، 2.6-41.5 ؛ p = 0.029) و NT -3 (+32.9 نانوغرام/مل [95 ٪ CI، 12.3-53.4 ؛ p = 0.004])، على التوالي. كشف تحليل الانحدار عن وجود علاقة إيجابية كبيرة بين التغيرات في مستويات BDNF والتغيرات في مستويات NT -4/5 من خط الأساس إلى ما بعد التمرين مباشرة في مجموعة التدريب المشتركة (R2 = 0.345، p = 0.034) ولكن ليس مجموعات التدخل الأخرى. تشير النتائج إلى أن التدريب على المقاومة الحادة والتمارين المشتركة تزيد من عوامل التغذية العصبية لدى البالغين الذين يعانون من زيادة الوزن غير النشطين جسديًا. هناك حاجة إلى مزيد من الدراسات لتحديد الأهمية البيولوجية للتغيرات في الاستجابات العصبية لدى الرجال الذين يعانون من زيادة الوزن والآثار المزمنة لبروتوكولات التمرين هذه .ClinicalTrials.gov, NCT02915913 (التاريخ: 22 سبتمبر 2016). The purpose of this study was to compare the neurotrophic factor response following one session of high-intensity exercise, resistance training or both in a cohort of physically inactive overweight adults aged 18-30 years old. A randomized, parallel-group clinical trial of 51 men (23.6 ± 3.5 years; 83.5 ± 7.8 kg; 28.0 ± 1.9 kg/m2) who are physically inactive (i.e., 6 months) and are either abdominally obese (waist circumference ≥90 cm) or have a body mass index, BMI ≥25 and ≤ 30 kg/m2 were randomized to the following four exercise protocols: high-intensity exercise (4 × 4 min intervals at 85-95% maximum heart rate [HRmax] interspersed with 4 min of recovery at 75-85% HRmax) (n = 14), resistance training (12-15 repetitions per set, at 50-70% of one repetition maximum with 60 s of recovery) (n = 12), combined high-intensity and resistance exercise (n = 13), or non-exercising control (n = 12). The plasma levels of neurotrophin-3 (NT-3), neurotrophin-4 (also known as neurotrophin 4/5; NT-4 or NT-4/5), and brain-derived neurotrophic factor (BDNF) were determined before (pre-exercise) and 1-min post-exercise for each protocol session. Resistance training induced significant increases in NT-3 (+39.6 ng/mL [95% CI, 2.5-76.6; p = 0.004], and NT-4/5 (+1.3 ng/mL [95% CI, 0.3-2.3; p = 0.014]), respectively. Additionally, combined training results in favorable effects on BDNF (+22.0, 95% CI, 2.6-41.5; p = 0.029) and NT-3 (+32.9 ng/mL [95% CI, 12.3-53.4; p = 0.004]), respectively. The regression analysis revealed a significant positive relationship between changes in BDNF levels and changes in NT-4/5 levels from baseline to immediate post-exercise in the combined training group (R2 = 0.345, p = 0.034) but not the other intervention groups. The findings indicate that acute resistance training and combined exercise increase neurotrophic factors in physically inactive overweight adults. Further studies are required to determine the biological importance of changes in neurotrophic responses in overweight men and chronic effects of these exercise protocols.ClinicalTrials.gov, NCT02915913 (Date: September 22, 2016).

Thus, the aim of this study was to compare the acute effects of high-intensity aerobic interval training (HIIT), progressive resistance training (PRT), or combined training (PRT + HIIT) on executive function indicators in overweight inactive adult men (aged 18-30 years old). The participants were screened and excluded for medical conditions known to impact cognitive functioning, which was measured with the Montreal Cognitive Assessment (MoCA) screening cognitive test. A randomised, parallel-group clinical trial was conducted among 36 adults who were randomly assigned to a HIIT (n = 12), PRT (n = 7), PRT + HIIT (n = 7), or control group (n = 10) until the energy expenditure of 400-500 kcal. Cognitive inhibition and attention capacity were examined using the Stroop test and d2 test of attention, respectively, and were obtained pre-exercise for baseline measurement and 1 min post-exercise for each exercise training modality. Cognitive inhibition measured by the Stroop test was improved after the HIIT protocol for the domains of reading by +5.89 (η2 = 0.33), colour naming +9.0 (η2 = 0.60), interference +10.1 (η2 = 0.39), and index interference +6.0 (η2 = 0.20). Additionally, the PRT + HIIT group had an increase for the reading condition of +7.1 (η2 = 0.40), colour naming +7.5 (η2 = 0.80), and interference +5.8 (η2 = 0.39). In regard to attentional capacity, the HIIT group elicited small to medium improvements in the concentration level domain of +21.7 (η2 = 0.44), total performance domain +56.6 (η2 = 0.50), and consistency domain -3.0 (η2 = 0.27). These results were similar in the PRT and PRT + HIIT groups in the concentration level and items-processed domains (P < 0.05). In conclusion, acute HIIT and PRT + HIIT sessions reported important effect sizes than PRT alone for cognitive inhibition and attention capacity. Taken together, the results suggest that even short-term exercise interventions can enhance overweight adults' executive functions.

It is well known that physical exercise modifies plasma levels of testosterone and cortisol. However, the effect of high-intensity interval training (HIIT) on the plasma hormone levels is controversial. The aim of the study was to compare the effects of HIIT exercise or submaximal continuous aerobic exercise on circulating testosterone and cortisol levels in active male collegiate students. Methods: Thirteen moderately-active young adult males (20.2 (SD 2.1) years old) completed a HIIT (20 min of 15 s intervals of running at 110% of maximum oxygen consumption interspersed with 15 s of active rest at 40% of maximum oxygen consumption) and a continuous aerobic exercise (AEE) 20 min at 70–75% of maximum oxygen consumption. The mean total workload of both protocols was the same for each exercise session. Blood samples were collected pre-session (rest), immediately after the session (0 h), and 12 h post-session (12 h). Results: Both exercise protocols, similarly increased plasma levels of free testosterone immediately post-exertion (p < 0.05 AEE and p < 0.01 HIIT). No differences were observed between the conditions in the concentration of testosterone at 12 h. Cortisol level and Testosterone/Cortisol (T/C) ratio remained constant for all measurements, regardless of the type of exercise performed. Conclusion: The testosterone concentrations rose significantly post intervention in both HIIT and AEE condition, but 12 h post intervention there was no difference between conditions, decreasing to baseline (pre-intervention). The T/C ratio decreased significantly (below baseline) only in the HIIT condition 12 h post intervention.

Aunque existe evidencia consistente de los efectos positivos de la actividad física en varios aspectos de la salud, la mayoría de los adolescentes en Colombia son sedentarios. Por lo tanto, es importante implementar estrategias que generen cambios en el estilo de vida. El estudio HEPAFIT tiene como objetivo examinar si un programa de ejercicio de 6 meses tiene beneficios para el contenido de grasa hepática y los resultados de salud cardiovascular entre adolescentes con sobrepeso/obesidad de Bogotá, Colombia. En conjunto, se incluirán 100 adolescentes sedentarios con sobrepeso/obesidad (de 11 a 17 años) que asisten a dos escuelas públicas en Bogotá, Colombia, en un ensayo controlado aleatorizado de grupos paralelos. Los adolescentes serán asignados aleatoriamente a un grupo de intervención siguiendo uno de los cuatro planes de estudio: (1) el plan de estudios estándar de educación física (60 minutos por semana de actividad física, n = 25) a una intensidad baja a moderada; (2) un plan de estudios de educación física de alta intensidad (HIPE, n = 25), que consiste en juegos de resistencia y resistencia y actividades no competitivas, como correr, gymkhanas, levantar, empujar, luchar o acarrear, durante sesiones de 60 minutos, tres veces por semana, con un objetivo de gasto de energía de 300 a 500 kcal/sesión a una frecuencia cardíaca máxima del 75-85% (HRmax); (3) un plan de estudios de educación física de intensidad baja a moderada (LIPE, n = 25) que consiste en juegos de resistencia y resistencia y actividades no competitivas (por ejemplo, perseguir, correr, driblear o saltar) durante sesiones de 60 minutos, tres veces por semana con un objetivo de gasto de energía de 300 kcal/sesión al 55-75% HRmax; y (4) un plan de estudios combinado de HIPE y LIPE (n = 25). La HIPE, LIPE y las intervenciones combinadas se realizaron además del plan de estudios estándar de educación física. El resultado primario para la efectividad es el contenido de grasa hepática, medido por el parámetro de atenuación controlada 1 semana después del final del programa de intervención. El enfoque traslacional puede ser adecuado para recopilar nueva información en un entorno escolar sobre los posibles efectos de las intervenciones de actividad física para reducir el contenido de grasa hepática y mejorar los perfiles metabólicos y la salud cardiometabólica de los adolescentes con sobrepeso/obesos. Esto puede conducir a un uso más eficiente de los recursos de educación física escolar.ClinicalTrials.gov, NCT02753231 . Inscrita el 21 de abril de 2016. Une proportion considérable de jeunes contemporains présentent un risque élevé de troubles liés à l'obésité tels que les maladies cardiovasculaires, le syndrome métabolique ou la stéatose hépatique non alcoolique (SHNA). Bien qu'il existe des preuves constantes des effets positifs de l'activité physique sur plusieurs aspects de la santé, la plupart des adolescents en Colombie sont sédentaires. Il est donc important de mettre en œuvre des stratégies qui génèrent des changements de mode de vie. L'étude HEPAFIT vise à examiner si un programme d'exercice de 6 mois présente des avantages pour la teneur en graisse hépatique et les résultats en matière de santé cardiovasculaire chez les adolescents en surpoids/obèses de Bogotá, en Colombie. Au total, 100 cents adolescents sédentaires en surpoids/obèses (âgés de 11 à 17 ans) fréquentant deux écoles publiques de Bogotá, en Colombie, seront inclus dans un essai contrôlé randomisé en groupes parallèles. Les adolescents seront répartis au hasard dans un groupe d'intervention selon l'un des quatre programmes suivants : (1) le programme d'éducation physique standard (60 minutes par semaine d'activité physique, n = 25) à une intensité faible à modérée ; (2) un programme d'éducation physique de haute intensité (HIPE, n = 25), composé de jeux d'endurance et de résistance et d'activités non compétitives, telles que la course, les gymkhanas, le levage, la poussée, la lutte ou le halage, pour des sessions de 60 minutes, trois fois par semaine, avec un objectif de dépense énergétique de 300 à 500 kcal/session à une fréquence cardiaque maximale de 75 à 85 % (HRmax) ; (3) un programme d'éducation physique d'intensité faible à modérée (LIPE, n = 25) composé de jeux d'endurance et de résistance et d'activités non compétitives (par exemple, chasser, sprinter, dribbler ou sauter) pour des sessions de 60 minutes, trois fois par semaine avec un objectif de dépense énergétique de 300 kcal/session à 55-75 % HRmax ; et (4) un programme combiné HIPE et LIPE (n = 25). Les interventions HIPE, LIPE et combinées ont été réalisées en plus du programme d'éducation physique standard. Le principal critère d'évaluation de l'efficacité est la teneur en graisse du foie, mesurée par le paramètre d'atténuation contrôlée 1 semaine après la fin du programme d'intervention. L'accent mis sur la traduction peut convenir à la collecte de nouvelles informations en milieu scolaire sur les effets possibles des interventions d'activité physique pour réduire la teneur en graisse du foie et améliorer les profils métaboliques et la santé cardiométabolique des adolescents en surpoids/obèses. Cela peut conduire à une utilisation plus efficace des ressources scolaires en matière d'éducation physique.ClinicalTrials.gov, NCT02753231 . Enregistré le 21 avril 2016. A considerable proportion of contemporary youth have a high risk of obesity-related disorders such as cardiovascular disease, metabolic syndrome, or non-alcoholic fatty liver disease (NAFLD). Although there is consistent evidence for the positive effects of physical activity on several health aspects, most adolescents in Colombia are sedentary. It is, therefore, important to implement strategies that generate changes in lifestyle. The HEPAFIT study aims to examine whether a 6-month exercise program has benefits for hepatic fat content and cardiovascular health outcomes among overweight/obese adolescents from Bogotá, Colombia.Altogether, 100 hundred overweight/obese, sedentary adolescents (aged 11-17 years) attending two public schools in Bogotá, Colombia, will be included in a parallel-group randomized controlled trial. Adolescents will be randomly assigned to an intervention group following one of four curricula: (1) the standard physical education curriculum (60 min per week of physical activity, n = 25) at low-to-moderate intensity; (2) a high-intensity physical education curriculum (HIPE, n = 25), consisting of endurance and resistance games and non-competitive activities, such as running, gymkhanas, lifting, pushing, wrestling, or hauling, for 60-min sessions, three times per week, with an energy expenditure goal of 300 to 500 kcal/session at 75-85% maximum heart rate (HRmax); (3) a low-to-moderate intensity physical education curriculum (LIPE, n = 25) consisting of endurance and resistance games and non-competitive activities (e.g., chasing, sprinting, dribbling, or hopping) for 60-min sessions, three times per week with an energy expenditure goal of 300 kcal/session at 55-75% HRmax; and (4) a combined HIPE and LIPE curriculum (n = 25). The HIPE, LIPE, and combined interventions were performed in addition to the standard physical education curriculum. The primary outcome for effectiveness is liver fat content, as measured by the controlled attenuation parameter 1 week after the end of the intervention program.The translational focus may be suitable for collecting new information in a school setting on the possible effects of physical activity interventions to reduce liver fat content and to improve metabolic profiles and the cardiometabolic health of overweight/obese adolescents. This may lead to the more efficient use of school physical education resources.ClinicalTrials.gov, NCT02753231 .

Background: Studies were performed in order to determine the existing relationship between body composition and both physical activity (PA) levels and food habits. Nevertheless, no study has yet examined if the association between adiposity and PA in children is moderated by adherence to the Mediterranean diet (MD). Methods: the cross-sectional and associative analysis involved a total of 370 children (55.1% boys) aged 6–13, from six different schools from the Murcia region of Spain. Results: The different values of moderator [adherence to the MD expressed as a Mediterranean Diet Quality Index (KIDMED) score] are shown by the slope and the different areas of significance. The first area was shown below ≤3.8, indicating that the unfavorable influence of excess of adiposity on PA could be intensified for children in this area. The second area was a significant positive area was shown above ≥9.3, expressing that the unfavorable influence of adiposity could be reduced for those who were above this estimation point. Conclusion: Our findings reveal that the adverse effects of excess adiposity on PA can be moderated by adherence to the MD among schoolchildren.

However, its effects on explosive and endurance performance at high altitude had not been studied. Therefore, the aim of this study was to determine the effects of a sea level short-term (i.e., 4-week) plyometric training program on explosive and endurance performance at sea level and at high altitude (i.e., 3,270 m above sea level). Participants were randomly assigned to a control group (n = 12) and a plyometric training group (n = 11). Neuromuscular (reactive strength index - RSI) and endurance (2-km time-trial; running economy [RE]; maximal oxygen uptake - VO2max) measurements were performed at sea level before, at sea level after intervention (SL +4 week), and at high altitude 24-h post SL +4 week. The ANOVA revealed that at SL +4 week the VO2max was not significantly changed in any group, although RE, RSI and 2-km time trial were significantly (p < 0.05) improved in the plyometric training group. After training, when both groups were exposed to high altitude, participants from the plyometric training group showed a greater RSI (p < 0.05) and were able to maintain their 2-km time trial (11.3 ± 0.5 min vs. 10.7 ± 0.6 min) compared to their pre-training sea level performance. In contrast, the control group showed no improvement in RSI, with a worse 2-km time trial performance (10.3 ± 0.8 min vs. 9.02 ± 0.64 min; p < 0.05; ES = 0.13). Moreover, after training, both at sea level and at high altitude the plyometric training group demonstrated a greater (p < 0.05) RSI and 2-km time trial performance compared to the control group. The oxygen saturation was significantly decreased after acute exposure to high altitude in the two groups (p < 0.05). These results confirm the beneficial effects of sea level short-term plyometric training on explosive and endurance performance at sea level. Moreover, current results indicates that plyometric training may also be of value for endurance athletes performing after an acute exposure to high altitude.

However, given that the DXA technique is impractical for routine field use, there is a need to investigate other methods that can accurately determine BF%. We studied the accuracy of bioelectrical impedance analysis (BIA) technology, including foot-to-foot and hand-to-foot impedance, and Slaughter skinfold-thickness equations in the measurement of BF%, compared with DXA, in a population of Latin American children and adolescents with an excess of adiposity. A total of 127 children and adolescents (11–17 years of age; 70% girls) from the HEPAFIT (Exercise Training and Hepatic Metabolism in Overweight/Obese Adolescent) study were included in the present work. BF% was measured on the same day using two BIA analysers (Seca® 206, Allers Hamburg, Germany and Model Tanita® BC-418®, TANITA Corporation, Sportlife Tokyo, Japan), skinfold measurements (Slaughter equation), and DXA (Hologic Horizon DXA System®, Quirugil, Bogotá, Columbia). Agreement between measurements was analysed using t-tests, Bland–Altman plots, and Lin’s concordance correlation coefficient (ρc). There was a significant correlation between DXA and the other BF% measurement methods (r > 0.430). According to paired t-tests, in both sexes, BF% assessed by BIA analysers or Slaughter equations differ from BF% assessed by DXA (p < 0.001). The lower and upper limits of the differences compared with DXA were 6.3–22.9, 2.2–2.8, and −3.2–21.3 (95% CI) in boys and 2.3–14.8, 2.4–20.1, and 3.9–18.3 (95% CI) in girls for Seca® mBCA, Tanita® BC 420MA, and Slaughter equations, respectively. Concordance was poor between DXA and the other methods of measuring BF% (ρc < 0.5). BIA analysers and Slaughter equations underestimated BF% measurements compared to DXA, so they are not interchangeable methods for assessing BF% in Latin American children and adolescents with excess of adiposity.
