Speed Improvement Focus: THE IMPORTANCE OF THE HIP EXTENSOR AND HIP FLEXOR MUSCLES IN SPRINTING

The hip extensors and the hip flexors are the strongest muscle groups within the lower extremity. The extensors are the primary movers, by acceleration, of the body’s center of gravity. The prime movers of the hips are also responsible for generating the most force during sprinting. Studies by Ralph Mann and others indicate that the bulk of forward propulsion and power generation in sprinting comes from the proximal musculature of the pelvis.
