The start rear hip angle ranges from what degrees?

• A. 100-120 degrees
• B. 110-130 degrees
• C. 120-140 degrees
• D. 90-110 degrees

Answer: (B)

The start rear hip angle shows how flexed the hip is in the set position, and that position sets up the hip extensors to fire efficiently for the first step. You want enough hip flexion to preload the glutes and hamstrings so they can snap into strong hip extension as the blocks release, but not so much that leverage or balance is lost. About 110 to 130 degrees is the sweet spot because it places the hip in a favorable length for rapid, powerful extension without sacrificing stability or drive into the ground. If the angle is smaller, the hip is more folded and may limit how much force the rear leg can produce quickly; if the angle is larger, the hip is more extended, which can reduce the ability to drive explosively from the start. Therefore, the typical range is around 110–130 degrees.
