Prevention of Groin Injuries in Rink Hockey

Prevention of Groin Injuries in Rink Hockey: A One Season Natural Experiment

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.

Study Overview

• Status: Completed
• Conditions: Groin Injury; Adductor Strain; Groin Strain
• Intervention / Treatment: Behavioral: Copenhagen Adduction Exercise

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).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Copenhagen Adduction Exercise Group; 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	Behavioral: Copenhagen Adduction Exercise; 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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	Every 14 days throughout the entire study (which lasts 7 months)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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	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	Every 7 days throughout the entire study (which lasts 7 months)
