AB la influencia del ejercicio f sico en sujetos entrenados tiene efectos beneficiosos en la condici n f sica y la composici n corporal Sin embargo el desentrenamiento tiene un efecto desfavorable en todas ellas Objetivo el prop sito del estudio fue analizar los cambios de la composici n corporal despu s de un periodo de desentrenamiento de seis semanas de duraci n en dos grupos uno de 43 j venes varones jugadores de f tbol grupo experimental GE n 43 y un grupo control de escolares no activos de la misma edad grupo control GC n 10 M todos las variables de composici n corporal fueron evaluadas mediante antropometr a para estimar la masa grasa MG y la masa muscular esquel tica MME y mediciones de bioimpedancia el ctrica para estimar agua corporal total ACT agua extra AEC e intracelular AIC Las mediciones se realizaron tanto en situaci n de entrenamiento como de desentrenamiento Resultados tras el desentrenamiento se encontraron diferencias significativas en el ACT 35 5 5 2 vs 36 7 4 9 kg el AIC 14 2 1 8 vs 14 8 1 6 kg y el AEC 21 5 3 6 vs 22 0 3 4 kg p 0 001 para todas las variables sin existir diferencias en los ratios AEC ACT 0 4 0 02 vs 0 4 0 02 y AIC ACT 0 6 0 02 vs 0 597 0 02 ambos p 0 05 La MG aument significativamente 8 6 3 2 vs 8 95 3 1 kg p 0 01 sin embargo la MME no sufri modificaciones 21 2 2 5 vs 22 22 2 8 kg p 0 05 Conclusiones el principal resultado de este estudio fue que en un periodo de desentrenamiento de seis semanas se observaron aumentos del ACT y de su distribuci n en el grupo de j venes futbolistas La importancia fisiol gica de esta desadaptaci n en el rendimiento deportivo tiene que ser analizada en futuros estudios
AB The infl uence of exercise in trained subjects has beneficial effects in the physical fi tness and body composition; however, detraining has an unfavorable effect in all of them. The current study was designed to ascertain the infl uence of a six week-detraining period on body composition in both well-trained young soccer players (GE, n = 43) and sedentary male adolescents (GC, n = 10). Forty-three well-trained soccer players and ten sedentary adolescents accepted to participate in the study. Body composition measurements included fat mass and skeletal muscle mass (SMM), which were estimated by anthropometry. In addition, total body water (TBW), intracellular water (ICW) and extracellular water (ECW) were assessed by bioelectrical impedance analysis (BIA) at the end of training and after detraining periods. After the six-week-detraining period, signifi cant increments were found in TBW (35.5 ± 5.2 vs.36.7 ± 4.9 kg; p  0.05) and ICW/TBW (0.6 ± 0.02 vs. 0.597 ± 0.02; p > 0.05) ratios. Finally, fat mass was significantly increased (8.6 ± 3.2 vs. 8.95 ± 3.1 kg; p  0.05) ratios. Finally, fat mass was significantly increased (8.6 ± 3.2 vs. 8.95 ± 3.1 kg; p  0.05). After a six-week detraining period, body composition changed signifi cantly in well-trained adolescents. The main fi nding of this study was that increments of TBW and water distribution were observed in the soccer group, which refl ects an increase of fat free mass compartment. The physiological importance of this miss-adaptation needs to be elucidated in future research. Further studies on this topic are still required to assess its impact on physical performance.
