PMID 37795333WHAT IT FOUND
Collegiate soccer teams that used the 11+ injury prevention warm-up more frequently had better win-loss records than teams that used it less or not at all.
High compliance was linked to more wins and fewer losses than moderate compliance, but not significantly fewer losses than low compliance.
Key findings
01Intervention teams had significantly more wins and fewer losses than control teams, with no difference in ties.
02Highly compliant teams had more wins than moderately or lowly compliant teams.
03Highly compliant teams had fewer losses than moderately compliant teams, but not significantly fewer than lowly compliant teams.

What it does not show
This was a post-hoc analysis, not a pre-registered primary outcome, which lowers certainty. Compliance was tracked at the team level, not the individual player level. The study only included male collegiate soccer players, so results may not apply to women or other sports. Only one season was analyzed. Four intervention teams dropped out and were excluded from the analysis.
Declared interests
The authors declare no conflicts of interest.
The easy way to misread this
Do not assume that using the 11+ directly causes better win-loss records. This is an observational post-hoc analysis of a trial, and compliance was not randomized. Highly compliant teams may have had other advantages, such as better coaching or resources, that contributed to their performance.
