Not Applicable

Completed

• Conditions: Groin Strain; Adductor Strain; Groin Injury
• Interventions: Behavioral: Copenhagen Adduction Exercise

• Registration Number: NCT05994469
• Lead Sponsor: University of Oviedo

Brief Summary

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.

Detailed Description

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).

Arm && Interventions

Group	Intervention	Description
Copenhagen Adduction Exercise Group	Copenhagen Adduction Exercise	there is no control group, all teams can implement the intervention protocol that better fits their normal schedule, the intervention can consist of 1 or 2 Copenhagen Adduction Exercise sessions per week

Primary Outcome Measures

Name	Time	Method
Bi-Weekly prevalence of groin problems	Every 14 days throughout the entire study (which lasts 7 months)	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

Secondary Outcome Measures

Name	Time	Method
Adherence to the intervention	Every 7 days throughout the entire study (which lasts 7 months)	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
hockey exposure	Every 7 days throughout the entire study (which lasts 7 months)	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
