Effects of a loaded change of direction training program on physical performance in U-19 elite soccer players

Abstract

Changes of direction are one of the most repeated actions during football matches, which is why the inclusion of these actions in the training of the football player must be a fundamental aspect. The aim of this study was to assess the effects of 6-week a loaded change of direction (COD) movements training on speed, jump, COD speed, and repeated sprint ability (RSA) in soccer players. The main results show that the effect of loaded COD movements training using a weighted vest on the physical performance of soccer players is significantly greater compared to the FIFA 11 prevention program. This study shows that including an additional load in COD exercises is a good method to increase performance on key variables for soccer players.
