This study was carried out in order to compare certain physical fitness parameters of young basketball and football players. Basketball players, who are playing in U16 league (n=12), and football players playing in U17 league (n=10) participated in the study voluntarily. Groups were separated into two as the basketball group (BG) and the football group (FG). BG has a body weight mean of 74.13±7.26 kg, a height mean of 187.50±7.03 cm, and an age mean of 16. FG has a body weight mean of 68.0±7.95 kg, a height mean of 178.4±5.31 cm, and an age mean of 17. Participants were applied performance tests, which are composed of sit and reach test, leg strength, hand grip strength, flexibility, 20 m sprint, and flamingo balance test among physical fitness parameters. Data obtained were analysed using SPSS 19.0 package program, and Mann Whitney U test was used to compare two groups. While there was no meaningful difference between strength and flexibility values (p>0.05), a meaningful difference occurred in favour of FG in 20 m speed test (p<0.05). As a result, the difference that occurred in speed only makes us think that height and body weight in basketball players can impact speed and agility negatively compared to football players.
