Effects of a Groin Pain Prevention Program in Male High School Soccer Players: A Cluster-Randomized Controlled Trial.
Kazuki Fujisaki, Kiyokazu Akasaka, Takahiro Otsudo and 3 others
PMID 35949380WHAT IT FOUND
Adding Nordic hamstring exercises to the Copenhagen adduction exercise lowered groin pain rates more than the adduction exercise alone in high school soccer players.
Both groups had fewer time-lost injuries than controls. The combined program appears superior for prevention.
Key findings
01The group doing both Copenhagen adduction and Nordic hamstring exercises had a significantly lower frequency of groin pain than the control group, and a lower rate than the group doing only Copenhagen adduction.
02Both intervention groups had significantly fewer groin pain injuries that caused time lost from sport compared to the control group.
03There was no significant difference in the severity of groin pain (days lost) between the intervention groups and the control group.

What it does not show
The study used cluster randomization by school, which can increase the risk of false positives. Injuries were self-reported, which may lead to measurement bias. The sample was limited to top-tier male high school soccer players, so results may not apply to recreational players or other levels. The study duration was only 16 weeks, so long-term effects are unknown. The number of severe injuries was very small, making it difficult to detect differences in injury severity.
Declared interests
The authors report no conflicts of interest.
The easy way to misread this
Do not assume the combined program reduces the severity of groin pain once it occurs. The study found no significant difference in the number of days lost per injury between the intervention groups and the control group, despite fewer injuries overall.
