Rink hockey teams from senior category (adults) will be recruited to implement a groin injury prevention program consisting on the Copenhagen Adduction Exercise (CAE) throughout the regular season, 0 times, once or twice per week (september 2023-march 2024) Weekly team exposure to training sessions and games will be collected as well as cases of groin problems in the entire population When the season ends, the number of groin problems will be compared between teams that used the prevention program once a week against twice a week or no sessions a week.
Rink hockey teams will be offered a prevention program consisting on the CAE to be performed during the season. Teams will decide to implement the protocol once, twice or 0 times per week, depending on their schedule. No formal control group will be set, comparison of injuries will be performed between teams that used +80% of the total possible sessions and -80% (28 weeks equals a potential 42 CAE sessions throughout the season). On a weekly basis, coaches will be contacted to report number of training sessions, games, and training sessions where they implemented CAE. Bi-weekly, players will report any episode of groin problems (both leading to time-loss and those only affecting performance while not limiting participation).

The CAE is performed by side-lying on the floor with the dominant lower limb supported in the air by a teammate, the hip is adducted until the body forms a straight line from the ankles to the shoulders (concentric phase), then the player is instructed to lower the body slowly (eccentric phase) until reaching the floor to start the next repetition.

Bi-Weekly prevalence of groin problems
number of groin pain complaints in a 14-day frame, groin pain is described as pain in the groin region which emerges from performing exercise and may be indicative of an injury to the adductor muscles, abdominals, hip flexors, or pubic joint
Time frame: Every 14 days throughout the entire study (which lasts 7 months)
Adherence to the intervention
Since the intervention is implemented on a weekly basis, the number of sessions performed by the participating teams will be collected to calculate the total compliance with the intervention. From a total of 56 possible sessions a team may complete 47 which equals 83% compliance
Time frame: Every 7 days throughout the entire study (which lasts 7 months)
hockey exposure
number of training sessions and games per week this metric is collected to calculate exposure hours, so that groin problems can be compared as nº of injuries / 1000 hours of exposure, as the International Olympic Committee recommends
Time frame: Every 7 days throughout the entire study (which lasts 7 months)
