High-Load Strength Training Reduces Injury Incidence and Injury Burden and Improves Physical Fitness in Young Highly Trained Soccer Players.

Soccer injuries, particularly to the hamstrings and groin, are common in young players, and coaches often wonder whether structured strength work can meaningfully change that risk rather than just build muscle. This trial compared 12 weeks of high-load strength training targeting the gluteal and hamstring muscles, added to normal soccer training, against normal soccer training alone in 20 young highly trained players split evenly between groups. The group doing the added strength work had fewer injuries and fewer days lost to injury than the group doing only regular training, along with greater gains in jumping, change of direction, sprinting, and strength balance measures. These are striking differences, but the trial involved only 20 players total, so the findings, while statistically significant, come from a small sample and would benefit from replication in larger groups before being treated as settled.

If you play soccer or coach young athletes, you've probably heard that strength training can help prevent injuries, but the evidence for exactly how much it helps has been limited. This study looked at 20 young, highly trained soccer players over 12 weeks, where half did their usual soccer training plus a high-load strength program focused on the glutes and hamstrings, while the other half did only their usual training. The players who did the extra strength training had noticeably fewer injuries and spent far fewer days out due to injury compared to those who trained as usual.

They also improved more in things like jumping, sprinting, and quick changes of direction. These results are encouraging, but this was a small study with only 10 players in each group, so the findings would need to be confirmed in bigger groups of athletes before anyone could say with confidence how reliably this approach reduces injuries across different teams and settings.

This trial speaks to a practical question in sports physiotherapy: does adding targeted high-load strength training to regular soccer training meaningfully reduce injury incidence and burden in young, highly trained players, beyond simply improving fitness markers. The randomised design compared an experimental group performing a 12-week high-load program targeting gluteal and hamstring musculature alongside usual training, against a control group doing usual soccer training only, with injury incidence and burden tracked throughout the intervention and fitness tested before and after. The results showed statistically significant reductions in both injury incidence (1.31 vs 11.34 per 1000 hours) and injury burden (19.72 vs 304.66 days lost per 1000 hours) favouring the strength-training group, alongside significantly greater improvements in jumping, change of direction, sprinting, and imbalance strength tests, with large reported effect sizes.

This adds trial-level support, rather than only observational or mechanistic evidence, to the idea that targeted strength work may relate to fewer injuries in this population. However, the sample was small, only 10 players per group, which limits how confidently these estimates generalise to broader populations, other age groups, or different training contexts. The abstract does not report adverse events, so nothing can be said about the safety of the loading protocol itself, and longer-term follow-up beyond the 12-week window was not described.
