Resumen

Background: The off-season period in soccer leads necessarily to changes in fitness status. However, there is a lack of systematization that allows identifying the magnitude of these changes in groups participating in off-season training programs compared with those subjected to training cessation. Objective: This systematic review with meta-analysis was conducted to assess the effects of training cessation in off-season training programs on men soccer players’ body fat, maximal oxygen uptake (VO2max), yo–yo intermittent recovery test (YYIRT), vertical jump, sprinting time, and repeated-sprint ability. Methods: To qualify for inclusion in the systematic review, studies must have included: (1) a detraining period of ≥ 2 weeks; (2) controlled trials or cohorts of healthy men soccer players with no restriction on age; and (3) a pre–post training cessation or off-season training programs measure of body fat (%), VO2max (mL kg−1 min−1), YYIRT performance (meters), vertical jump (height), sprinting (time), and repeated-sprint ability (total time). Results: The electronic search yielded 563 articles, and 12 were subsequently included. Significant (all p < 0.05) detrimental training cessation effects were noted for body fat (ES = 0.26), VO2max (ES = − 1.48), YYIRT (ES = − 0.46), vertical jump (ES = − 0.81), and repeated-sprint ability (ES = 0.68). Similarly, significant (all p < 0.05) detrimental off-season training programs effects were noted for body fat (ES = 0.26), VO2max (ES = − 0.48), vertical jump (ES = − 0.51), and sprinting time (ES = 0.86). When training cessation and off-season training programs effects were compared, greater detrimental effects were noted after training cessation for VO2max (p = 0.002) and repeated-sprint ability (p < 0.001). Conclusions: Detrimental effects on body composition and physical fitness were observed after both training cessation and off-season training programs. However, off-season training programs seem to ameliorate such detrimental effects on VO2max and repeated-sprint ability to some extent. The results presented here call for the implementation of more effective off-season training programs among male soccer players.
