ORAL ABSTRACTS - SATURDAY, 23 MAY 2015study was to investigate the relations between training load, sleep and recovery in elite youth soccerplayers.Methods: Fifty-nine elite youth soccer players (16.4 ± 1.5 years of age) from an U19, U17 and U15squad participated in the study. Training duration (minutes), session Rating of Perceived Exertion(6-20), sleep duration (minutes), sleep quality (1-10) and Total Quality Recovery (TQR, 6-20) weredetermined during 4 in-season weeks. Pearson correlation coefficients were calculated to examinethe relations.Results: Average training load was 1136 ± 445 (AU) per day and players slept 8.6 ± 1.3 hours pernight. Sleep quality was rated as 7.0 ± 1.2, indicating good sleep. Average TQR score was 15.7 ±1.76, which corresponds with good recovery. Higher training load was related to poorer TQR (r= -0.26; N=879; p
