Brief Summary

Hip and groin injuries affect approximately 21% of professional athletes annually, causing significant time loss. As roughly 48% of these cases result from non-contact mechanisms, they are potentially preventable through optimized diagnostic screening. Evidence strongly links restricted hip range of motion (ROM) and strength deficits to an increased injury risk. This project aims to (1) develop a rigorously validated diagnostic testing procedure by comparing different joint positions, movement velocities, and muscle contractions to establish a preventive "gold standard" screening battery. dditionally, (2) pilot targeted prevention interventions over a competitive season. Using a crossover design, the research evaluates three protocols: Strength-focused,Flexibility-focused:and control group. (3) Implement of a Centralized Injury Reporting System. Combining comprehensive diagnostic screening with these practical interventions will yield a powerful tool for clinicians and coaches to effectively reduce the incidence and burden of non-contact hip and groin injuries

Hip Injury

Outcome Measures

Primary Outcomes (1)

• Hip and Groin Injury Incidence During the Competitive Season

  The number of new hip and groin injuries occurring during the monitored competitive season among athletes participating in the different preseason intervention programs. Injury incidence will be recorded by team medical staff and expressed as the number of injuries per 1000 athlete-exposures.

  Through the competitive season, up to 9 months

Secondary Outcomes (6)

• Hip and Groin Injury Severity

  Through the competitive season, up to 9 months

• Hip and Groin Injury Burden

  Through the competitive season, up to 9 months

• Change in Hip Range of Motion (ROM)

  Baseline (Day 1, preseason screening) and 8 weeks (end of preseason intervention)

• Functional Lower Limb Performance

  Baseline (preseason) and post-intervention (end of preseason)

• Hip Adduction and Abduction Strength

  Baseline (Day 1, preseason screening) and 8 weeks (end of preseason intervention)

Study Arms (3)

Strength-focused

EXPERIMENTAL

Emphasizing specific joint stabilization and eccentric load tolerance, heavily utilizing the Copenhagen Adductor Exercise.

Other: Strength-focused

Flexibility-focused:

EXPERIMENTAL

Targeting functional hip ROM through stretching and dynamic mobility under load.

Other: Flexibility-focused

Control

NO INTERVENTION

Maintaining standard club warm-up and training regimens.

Interventions

Eligibility Criteria

• Age: 14 Years - 20 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Male or female competitive team sports.
• Registered members of participating team sports.
• Age 14 to 20 years.
• Participation in regular team training and competition during the study period.
• Medically cleared for full participation in training and match play at study entry.
• Willing and able to complete preseason testing and the assigned intervention program.
• Provided written informed consent. For participants younger than 18 years, parent or legal guardian consent will also be obtained.

You may not qualify if:

• Current hip or groin injury causing time loss or restricting full participation in training or competition at baseline.
• Lower extremity or lumbar spine injury at baseline that limits safe participation in testing or intervention exercises.
• Surgery involving the hip, groin, pelvis, lumbar spine, or lower extremity within the previous 6 months.
• Any neurological, musculoskeletal, cardiovascular, or other medical condition that would contraindicate participation in the intervention or testing procedures.
• Inability to complete baseline assessments.
• Planned absence during a substantial part of the preseason intervention period or competitive season.
• Noncompliance with study procedures or refusal to provide consent.
