Define Technique Then Assess Control
- Use a clear technical definition: sprint technique equals movement patterns to achieve the outcome.
- Assess how each athlete controls that technique rather than forcing a single 'ideal' style.
Four Acceleration Strategies
- Four whole-body acceleration strategies exist: bounders, striders, spinners and bouncers.
- Classifying by step length, contact and flight times helps link strategy to function and risk.
Strategy Predicts Tissue Risk
- Bounders (long flight) show higher calf/Achilles injury risk due to vertical impulse and high energy absorption.
- Spinners (high step-rate, low flight) show higher hamstring risk due to high biceps femoris loading and anterior pelvic tilt.
