Hip Biomechanics & Athletic Groin Pain
Adductor-related groin pain is one of the most prevalent conditions in football, rugby, and GAA. Isokinetic testing of hip adduction and abduction at constant angular velocities provides quantifiable benchmarks for adductor peak torque and the Adductor-to-Abductor (ADD:ABD) strength ratio.
Key Ratios & Sprinting Capacity
Adductor-to-Abductor (ADD:ABD) Ratio
Normative values indicate that hip adductor torque should be approximately 90% to 110% of abductor torque (0.90–1.10). ADD:ABD ratios below 80% correlate with increased risk of adductor strain injuries.
Hip Extension Peak Torque (Gluteus Maximus)
Hip extension torque capacity at 60°/s and 120°/s directly underpins horizontal ground reaction force production during acceleration phases in sprinting.
