Purpose : To analyze and compare the effects of 4 different resisted sprint training (RST) modalities on youth soccer players’ performance after 8 weeks training. Methods Forty-eight players were first randomly assigned to groups only then completed RST: horizontal sprint, vertical (VRS), combined unresisted sprint. Performance in jumps, change direction (COD) ability assessed 1 week before intervention. Magnitude-based inference analysis was performed for calculating within-group pre–post differences. In addition, an covariance test between-group comparison, using pretest values as covariates. After that, P effect statistic transformed magnitude-based inference. Results Within-group outcomes showed that all experienced improvements (small moderate) COD large) performance. Moreover, groups, except enhanced jump However, VRS improved jump. Between-group comparison revealed time compared with (moderate) (moderate large). countermovement other groups. Conclusions Independent orientation resistance applied, RST is effective method improving sprinting Nevertheless, may promote greater have a positive additional reduction deficit.
