Zusammenfassung:	Aim of the present study was to test if training frequency determines physical fitness and fat mass accumulation in prepubertal male tennis players (TP). Body composition scans (DXA), jump performance (SJ and CMJ) and 30 m running speed tests were conducted in 24 TP (10.6 years) and 17 physically active boys. Tennis players were divided into two groups (TP5: playing 5 d/week, n.=14; TP2: playing 2 d/week, n.=10). Compared to TP5 and TP2, controls had more total body fat (+23-28%) and fat mass in the trunk (+42-43%) and legs (+13-19%), respectively (P
