Low-load resistance training reduces injury incidence and burden, and improves the physical performance in youth soccer players

The inclusion of some specific strength training programs could be a key strategy to reinforce the injury prevention process. This study aimed to analyze the effects of a 12-week low-load resistance training program on injury incidence, burden, and physical fitness in semiprofessional youth soccer players. Twenty male players were randomly assigned to the experimental group (EG, n = 10 players), which performed a low-load resistance training program, or to the control group (CG, n = 10 players), which performed only their usual soccer training. Injury incidence and injury burden were registered during the intervention, as well as the physical fitness attributes: jumping, repeated sprint abilities (RSA), change of direction ability (CODA), linear sprints and isometric strength, at baseline and after the training program. A significant (p < 0.05) lower injury incidence was observed in EG (CG: 9.57 vs. EG: 0.00 injuries/1000 h of exposure) and a significant (p < 0.001) lower injury burden in the EG (CG: 317.83 vs. EG: 0.00 days of absence/1000 h of exposure). The ANCOVA model revealed significant between-group differences favoring the EG, showing significant higher improvements in all physical fitness attributes (p < 0.001–0.024). This study demonstrated the effectiveness of a low-load resistance training program in preventing injuries and improving physical condition in young soccer players.
