Introducción: recientes estudios han confirmado que el entrenamiento de fuerza en circuito podría reducir la masa grasa visceral en mujeres mayores obesas. Para seguir avanzando en esta línea de trabajo, nos propusimos determinar su impacto en marcadores de disfunción endotelial.Material y método: participaron voluntariamente 48 mujeres (70-75 años) con obesidad procedentes de la comunidad. De ellas, 24 fueron asignadas aleatoriamente al grupo experimental para desarrollar un programa de entrenamiento de fuerza en circuito de 6 estaciones durante 12 semanas con 3 sesiones/semana. Los marcadores de disfunción endotelial ensayados fueron: endotelina-1, molécula de adhesión intercelular-1 (ICAM-1) y molécula de citoadhesión vascular-1 (VCAM-1). Asimismo se evaluó su influencia en un test funcional para población mayor como el de sentarse levantarse en 30 segundos. Este protocolo fue aprobado por un comité de ética institucional. Resultados: tras completar el programa de intervención se observó un descenso significativo de los niveles plasmáticos de entotelina-1 (2,28 ± 0,7 vs. 1,98 ± 1,1 pg/ml; p = 0,019; d = 0,67) e ICAM-1 (290 ± 69 vs. 255 ± 76 ng/ml; p = 0,004; d = 0,92). También mejoró significativamente la puntuación del test funcional (18,7 ± 3,1 vs. 23,0 ± 3,6 repeticiones; p = 0,019; d = 0,98). Por el contrario, no se observaron cambios en el grupo control.Conclusión: el entrenamiento de fuerza en circuito mejora la disfunción endotelial presente en mujeres mayores obesas. Futuros estudios siguen siendo necesarios para consolidar su aplicación en clínica.

Objective: The overweight-related health problems among adolescents are obvious. Resistance training is recognized as a safe and efficacious exercise modality to have health-promoting effects in overweight adolescents. This study aimed to assess the efficacy of circuit resistance training (CRT) in improving inflammatory status, insulin resistance and body composition in overweight male adolescents. Materials and Methods: Twenty overweight adolescent boys (aged: 18.5 (±1), weight: 81.1 (±4.5), body mass index: 27.7 (±0.7)) completed this study. The participants were randomly and equally divided into two groups of control (CG; n=10) and circuit resistance training (CRT; n=10). The CG did their daily routine activities and the CRT group performed its training protocol 3 days a week for 6 weeks. Body composition components and serum variables were measured a day before and after the study. Insulin resistance index was measured by HOMA-IR. Results: The subjects in the CG showed significantly increased changes compared with pre-training values. Moreover, significant changes were found fort the changes of BW ( P -value= 0.005), BMI ( P -value= 0.001) and BF% ( P -value= 0.003) between groups. Conclusion: This study suggested that although six weeks of CRT failed to induce meaningful anti-inflammatory cytokine responses, and to improve body composition and HOMA-IR in overweight adolescent boys, but had protective effects on inflammatory status, HOMA-IR and body composition and prevented them from being deteriorated

Few studies have examined the improving effects of exercise on the association between metabolites of impaired protein metabolism and insulin resistance in obese children. Therefore, this study aims to investigate the effect of circuit resistance training (CRT) on plasma levels of amino acids, alpha-hydroxybutyrate (α-HB), mannose, and urinary levels of glycine conjugated adducts in obese adolescent boys. Forty obese adolescent boys (BMI above the 95th percentile) with an age range of 14-17 were randomly divided into CRT group (n= 20) and control group (n= 20). The CRT program (3 times/week, 70-80% of 1 repetition maximum) was performed for 8 weeks. The results indicated that the body composition and plasma levels of glucose, insulin resistance, valine, mannose, lysine and the sum of branched-chain amino acids (BCAAs) were decreased due to CRT. The plasma levels of asparagine, glycine, serine, and urinary levels of glycine conjugated adduct also increased in the CRT group. Although α-HB level decreased during CRT, it had no significant difference from that of the control group. It can be concluded that the improvement in obesity complications including insulin resistance in obese adolescent boys after CRT may be due to decrease in plasma levels of mannose and BCAAs and increase urinary metabolites. Novelty Bullets: • CRT improves glucose metabolism and insulin resistance in obese adolescent boys. • CRT decreases plasma levels of mannose and BCAAs and normalizes other amino acids. • CRT increases urinary levels of glycine conjugated adducts.
