To improve hamstring flexibility, which of the following should be contracted to facilitate reciprocal inhibition?

• A. Gluteals
• B. Quadriceps
• C. Gastrocnemius
• D. Hamstrings

Answer: (B)

To enhance hamstring flexibility through the concept of reciprocal inhibition, it is important to contract opposing muscle groups that create a relaxing effect on the target muscles. In this case, contracting the quadriceps facilitates this process. The quadriceps are the muscle group located at the front of the thigh, and when they contract, they trigger a reflex that relaxes the hamstrings located at the back of the thigh due to reciprocal inhibition. This physiological principle works because the nervous system regulates muscle contractions in a way that when one muscle group becomes active, the opposing muscle group must relax to allow for full and effective movement. By focusing on the quadriceps, the tension created in those muscles leads to a reduction in tension in the hamstrings, making it easier to achieve greater flexibility in that muscle group. This approach is particularly effective during stretching routines, which aim to improve overall muscle elasticity and length. In contrast, the other muscle groups mentioned, such as the gluteals, gastrocnemius, or the hamstrings themselves, do not have the same direct effect on facilitating reciprocal inhibition in this specific context of improving hamstring flexibility. The gluteals primarily affect hip extension and do not target the knee flexors directly, while the gastrocnemius
