description

[Resumen] El objetivo del estudio es analizar la influencia de la masa grasa total y su % respecto al peso corporal total, así como la masa grasa regionalizada (Σ pliegues tronco, Σ pliegues abdomen, cociente TS/TI, phantom (Ph) de los pliegues) y su % respecto a la masa grasa total, en relación al VO2max y los Umbrales Ventilatorios (VT1 y VT2) en jóvenes deportistas en función de su especialidad deportiva y grupo de edad. La muestra está compuesta por 400 deportistas de ambos sexos del Centro de Tecnificación de Cheste (Valencia) clasificados en 3 grupos de edad: 0,05) entre atletismo y natación. Para el caso de los grupos de edad se han encontrado diferencias significativas (p0,05) entre los grupos de <12-13 y 17-20 años [Abstract] The aim of the study is to analyse the influence of total fat mass and its % regarding total body weight, as well as the regionalized fat mass (Σ trunk folds, Σ abdominal folds, ratio TS/TI, phantom (Ph) of the folds) and its % regarding total fat mass in relation to VO2max and ventilatory thresholds(VT1, VT2) in young according to their sport specialty and age group. The sample is composed of 400 athletes of both sexes from Centro de Tecnificación de Cheste (Valencia) classified into 3 age groups: <12-13, 14-16 and 17-20 years of age, and endurance sports disciplines: athletics, swimming and triathlon (n = 134, n = 135 and n = 131 respectively). The physiological data was obtained from and ergospirometric incremental ramp test on a treadmill following the Wasserman protocol; and the anthropometric data from an anthropometric measurement following the ISAK protocol. The results obtained from the Variance Analysis (ANOVA) indicate significant differences (p<0,05) for the case of sport specialties, those being athletics, swimming and triathlon. But there were no significant differences (p<0,05) between athletics and swimming. For the case of age groups, the findings indicate significant differences (p<0,05) between the age groups 14-16 and 17-20, as well as <12-13 and 14-16 years of age. But this was not the case for the age groups <12-13 and 17-20 years of age.
