Hamstring Injuries in Sprinters Explained: Causes, Recovery, Prevention, and Performance Impact Sprinters worldwide experience acute hamstring injuries at rates exceeding almost all other athletic populations, making this specific muscle group the single greatest vulnerability in track and field. The hamstrings consist of three distinct muscles along the back of the thigh—the biceps femoris, semitendinosus, and semimembranosus—which work collectively to decelerate the lower leg and extend the hip. High-speed running creates extraordinary kinetic forces on these muscle groups, pushing biological tissue to its absolute mechanical limit. Sprinters from elite collegiate programs in the United States to professional training tracks across Europe routinely lose entire competitive seasons to recurring hamstring pathologies. Because…
