PERBEDAAN NILAI VITAL CAPACITY, FORCED VITAL CAPACITY DAN FORCED EXPIRATORY VOLUME IN ONE SECOND 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: Physical activity during childhood and adolescence has an important impact on health and life quality. The earlier study shown that regular exercise has significant impact to the lung and cardiovascular function. Every sport branches has different energy system based on the type of exercise they do. Objective: To find out the difference vital capacity, forced vital capacity and forced expiratory volume in one second values between sport branches on athlete in age 6-12 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, VC,FVC and FEV1 ware measured using Spirometer spirolab II. Kruskal-Wallis test was applied for statistical analysis.
