Which structures are emphasized by the straight leg bolster stretch?

• A. IT Band and TFL
• B. Hamstrings and Gracilis
• C. Rectus Femoris and Vastus Lateralis
• D. Gluteus Maximus and Piriformis

Answer: (A)

The stretch emphasizes the outer thigh and hip fascia and muscles. When the leg is kept straight and supported on a bolster, the iliotibial band (IT band) along the outer thigh and the tensor fasciae latae (TFL) at the hip are placed under lengthening tension as the leg rests in extension. The IT band is a long piece of fascia running from the hip to the knee, and the TFL often tightens with lateral hip use; together they respond most to a straight-leg position with support, producing the primary stretch along the lateral thigh and hip. This is why the IT band and TFL are the best targets for this setup. The other structures described correspond to different regions or movements: hamstrings and gracilis are more about the posterior/medial thigh; the rectus femoris and vastus lateralis are involved with the front thigh and knee extension; and the gluteus maximus and piriformis relate more to hip extension and deeper hip rotator work.
