PERBEDAAN NILAI TIDAL VOLUME, INSPIRATORY RESERVE VOLUME DAN INSPIRATORY CAPACITY ANTAR CABANG OLAHRAGA PADA ATLET USIA 6-12 TAHUN (Studi pada Cabang Olahraga Bola Voli, Sepak Bola, Renang dan Taekwondo di Kota Semarang)

Abstract

Background: The peak of human body growth and development happens during childhood with different intensity of activities and exercise. It influences the level of physical fitness and health. This research states that daily exercise has a significant impact towards the function of cardiorespiratory system. Each kind of sport has different energy system depends on the kind and the intensity of exercise. Aim: To prove the difference tidal volume, inspiratory reserve volume and inspiratory capacity on athlete in age 6-12 between swimmer, taekwondo player, football player and volleyball player in Semarang. Method: This cross-sectional study was done in 20 male athlete age 6-12 each sport branches, being in total 80 athlete. Among respiratory functions test, TV,IRV and IC ware measured using Spirometer spirolab II. Kruskal-Wallis test and One-way annova was applied for statistical analysis. Result: Mean TV values volleyball athlete is 1,12 L, football athlete 1,06 L, swimming athlete 1,27 L and taekwondo athlete 0,89 L. Mean IRV values volleyball athlete is 0,54 L, football athlete 0,70 L, swimming athlete 0,71 L and taekwondo athlete 0,67 L. Mean IC values volleyball athlete is 1,66 L, football athlete 1,76 L, swimming athlete 1,91 L and taekwondo athlete 1,56 L. Swimmer athlete has higher VC, IRV and IC values than other athlete. Conclusion: There is a significant difference TV values between sport branches in athlete age 6-12. Beside that, there is not a significant difference IRV and IC values between sport branches in athlete age 6-12.
