The purpose of this study is to investigate the effect of sports on some motoric, physical, and lung functions of athletes and sedentary individuals in the same age group with young individuals playing in high school teams in different sports branches. A total of 60 volunteer individuals, including 45 athletes (15 male basketball players, 15 male handball players, 15 male football players), and 15 male sedentary individuals participated in the study. FVC (l), FEV1 (l), PEF (l/s), FEF 25/75 (l/s) and MVV (l/min) values were not statistically different between the branches (p>0.05). FEV1 / FVC % values differed between branches (p<0.05). FEV1 / FVC % values differed between branches (p<0.05). There was no statistical difference between branches in 30 m speed values (p>0.05). 30 m durability at velocity values were found to be different between branches (p<0.05). There was no statistical difference between the branches according to their mean grip strength values (p>0.05). In our study, athletes who played in high school teams had better lung function than those who did not play sports with the same physical characteristics and when FEV1/FVC ratios were evaluated, the risk of developing obstructive and restrictive lung diseases was lower.
