Implication

Comparative study demonstrates reduced thigh muscle activation and greater initial knee stiffness in high-mileage runners, suggesting enhanced tendon-driven elastic efficiency across running speeds.

Key Points

To determine how running training volume influences lower limb muscle activation, joint stiffness regulation, and tendon energy storage across various running speeds.
Assessed 13 high-mileage runners (>45 km/wk) and 13 low-mileage runners (<15 km/wk) running at four controlled speeds (2.5–5.5 m/s).
Recorded lower limb biomechanics alongside surface electromyography of the thigh muscles before and during early stance.
High-mileage runners exhibited lower postlanding activations of the rectus femoris, vastus medialis, and semitendinosus muscles, with divergence between groups amplifying at faster speeds.
High-mileage runners showed elevated initial knee stiffness and earlier peak knee flexion velocity during impact, whereas low-mileage runners had higher stiffness during the weight acceptance phase.
Estimated elastic energy return about the ankle was greater in high-mileage runners, corresponding with lower muscular activation demands during ground contact.
