Resumen
To better understand the detraining effects in soccer, the purpose of the study was to ana-
lyse if performance level of soccer players modulate repeated-sprint ability (RSA) and inter-
mittent endurance changes during 2-weeks of detraining (i.e., in-season break). Seventeen
professional and sixteen young elite soccer players of two different teams performed, before
and after 2-weeks of detraining, the RSA test and the Yo-Yo Intermittent Recovery Test,
level 1 (YYIR1). Before detraining, professional players perform better (p < 0.05) RSA best
time (RSAbest) than young players. A decrease (p < 0.05) in RSAbest, RSA total time
(RSAtotal) and mean time (RSAmean) performance was observed in both teams, without
changes in RSA fatigue index (Sdec). No significant changes in distance covered during
YYIR1 was observed in any team. Before detraining, faster players from both teams (FG)
(following the median split technique, soccer players with RSAbest 3.95 s) performed bet-
ter (p < 0.01) in RSAtotal, RSAmean and RSAbest, but worse (p < 0.01) in Sdec. Although FG
and the slower players (SG, RSAbest > 3.95 s) showed a worse (p < 0.05) RSAtotal, RSAbest
and RSAmean performance after detraining (ES = 1.5, 1.4 and 2.9; ES = 0.6, 1.2 and 0.6; for
FG and SG, respectively), the deterioration was greater in the FG for RSAbest (p < 0.05) and
RSAtotal (ES = 1.46). After detraining, FG improved (p < 0.05) Sdec performance. In conclu-
sion, a 2-week in-season break (detraining) period induced a worse RSA, with no effect on
intermittent endurance in professional and elite young soccer players, with greater detrimen-
tal effects on RSAtotal and RSAbest in FG. In addition, Sdec does not seem to be sensitive to
changes in RSA after a 2-week in-season break.
