Relationship between cardiorespiratory capacity and body composition in 13-14 year-old swimmers

Abstract

This research refers to the correlation between cardiorespiratory capacity and body composition of 20 swimmers (10 of both sexes) aged 13-14 years, belonging to the EIDE Provincial Jorge Agustini Villasana. Cardiorespiratory capacity was assessed through the expiratory (ISE) and inspiratory (ISI) Skibinski index, and body composition was measured using weight, height and skinfolds to determine the body mass index (BMI), percentage of fat (%F), fat mass (FM), fat-free mass (FFM), ideal weight (IW) and percentage of ideal weight (%W). The results indicated that female swimmers have lower values ​​of BMI, FGM, IW, ISE and ISI than male swimmers, while the variables %F, FM and %WM are higher in male swimmers. The values ​​obtained from the comparison, Student T test, assert that the variables PI, %PI, %Fat, MG are higher in female swimmers than in male swimmers, showing values ​​of p < 0.05. While the values ​​reached in the variables weight, height, BMI, MLG, ISE and ISI are lower in female swimmers than in male swimmers, showing values ​​of p > 0.05. The variables of the body build weight, height, BMI, %Fat, MG, MLG, PI and %PI present a high, very high and perfect relationship between them, however, they show little association with the expiratory and inspiratory Skibinski index.
