Physical fitness related to performance in teenage futsal practitioners

Abstract

Introduction: Adequate levels of physical fitness can bring better results to athletes, avoiding injuries and increasing their performance. Objective: To analyze performance-related physical fitness in sub-17 adolescents, as well as to investigate their relationship with training frequency. Methods: A cross - sectional study was carried out with 30 male adolescents practicing futsal born in (2001 and 2002), from a school in the city of São Gonçalo do Amarante, Ceará. Information on body mass index, weekly training frequency and performance-related physical fitness were collected according to the Brazilian Sport Project (PROESP-BR). The tests performed were: Upper limb force (FMS) - 2kg medicineball pitch; Lower limb strength (IMF) - horizontal jump; Speed (running 20 meters); Agility (square test - 4 meters) and Cardiorespiratory Fitness Test (9 minute run / walk). Results: Adolescents presented adequate nutritional status with an overall mean of (21.33 ± 2.92). Adolescents who trained four to five times a week had a better cardiorespiratory test result (1848.7 ± 76.0) than those who trained two and three times (1414.5 ± 359.5 and 1753.2 ± 207, respectively, 5, p = 0.002). Higher prevalence of adolescents was classified as excellent only in the velocity test (30.0%). Conclusion: It is concluded that a higher frequency of weekly training is associated with an improvement in the performance of cardiorespiratory fitness. It is suggested that studies on physical fitness have their results presented to teachers and / or coaches of sports modalities as a tool to aid in the preparation of their training.
