Abstract
BUSTOS-VIVIESCAS, Brian Johan; MERCHAN OSORIO, Rony David and ALONSO ACEVEDO-MINDIOLA, Andrés. Association between adiposity variables and change of direction speed in young soccer players. Rev Cubana Invest Bioméd [online]. 2021, vol.40, n.1 Epub Apr 01, 2021. ISSN 1561-3011.
Introduction:
Identification of anthropometric variables related to performance in a given sport is a common topic of interest to health and sports professionals.
Objective:
Determine the influence of body mass index, fat mass, and fat-free mass on change of direction speed in young soccer players.
Methods:
A correlational descriptive quantitative study was conducted of a convenience sample of 21 soccer players. Change of direction speed was measured with the Meters Swerve Sprint Test, whereas body fat percentage was evaluated with an OMRON® BF-306 monitor. The data were analyzed with the statistical package PSPP, with application of the Shapiro-Wilk normality test and Pearson's correlational coefficient (confidence interval 95% and p-value 0,05).
Results:
Results show a normal distribution (p > 0,05). However, a significant relationship was not found between body mass (r = -0,29), fat mass (r = -0,06) and fat-free mass (r = 0,06; p > 0,05), and performance in the swerve speed test.
Conclusions:
The study found that there is not a significant relationship between body mass index, fat mass and fat-free mass, and change of direction speed in young soccer players.
