Objective To analyze the effects of detraining on body composition, vertical jumping and speed abilities. Methods Twenty two under‐17 soccer players (16.4 ± 0.4 years; 70.0 ± 7.1 kg; 175.9 ± 6.9 cm) were evaluated before and after two weeks of detraining. Anthropometric measurements, countermovement (CMJ) and squat jumps (SJ) and sprint speed tests were performed. Results There was a significant increase in body fat (p < 0.001) and despite the fact that the decrease in the speed was no significant (p > 0.05), an increase of 2.24% in the 0‐5 m time (ES = 0.78) and 0.97% in the 0‐20 m time (ES = 0.41) were observed. In addition, there was an upward trend in the SJ (p = 0.056). Conclusion Two weeks of detraining resulted in significant alterations of the body composition and in speed performance (from 0 to 5 m) in young elite soccer players.
