During Maximum Velocity, eccentric hip flexion occurs in which phase?

During Maximum Velocity, eccentric hip flexion occurs in which phase?

• A. Maximum Velocity early support.
• B. Maximum Velocity late support.
• C. Start.
• D. Acceleration.

Answer: (B)

During maximum velocity the leg is rapidly cycling and the critical transition happens as you move from stance into swing. In late support, the hip goes from extending to preparing the leg to swing, and the hip flexors lengthen under load to control that rapid change. This lengthening under tension is exactly what we call eccentric hip flexion, helping to brake the extension and set up the next forward leg recovery. So the action occurs in the late part of the support phase. In start or acceleration, the emphasis is more on powerful hip extension and knee drive, so the same eccentric control isn’t the primary feature there.
