Efeitos da prática de aero jump e ciclismo indoor sobre alguns aspectos da composição corporal de mulheres sedentárias

Abstract

This study had the purpose of comparing the effects of 12 weeks of aerobic jump and indoor cycling training upon some aspects of the body composition of sedentary women. Twenty women aged between 20 and 38 years were evaluated. The procedures used to access body composition were body mass, height and 7 skin folds (triceps, subscapular, chest, midaxillary, iliac crest, abdominal and midthigh) measures. The parameters measured were body mass index (BMI), body fat percentage and skin folds sum. The pre test data collection was performed before the 12 weeks of training and the post test data collection, after. The following results were observed: in the aerobic jump group there was a reduction of the skin folds sum from a mean value of 161,7 (47,85) to 155,4 (42,53) and in the indoor cycling group the three analyzed variables reduced, specially body fat percentage from 31,8 (6,54) to 29,7 (5,09). For the data analysis, descriptive statistics was applied, as well as the Wilcoxon Test for the comparison between pre and post training results and Kruskal-Wallis for the comparison between the groups, considering a 5% significance level. It was concluded that a 12 week training program of Aerobic Jump and Indoor Cycling were not sufficient to produce statistical significant alterations upon the studied variables. Nevertheless, it was observed that the alterations produced by the indoor cycling training were more relevant in some aspects of the body composition alterations in sedentary women.
