Acute Effects of Different Soft Tissue Techniques on Hamstring Tightness

Flexibility is one of the key components of health-related physical fitness and is influenced by various factors such as age, gender, joint structure, and muscle anatomy. Hamstring tightness can contribute to multiple lower extremity injuries. While traditional methods like stretching and myofascial release are commonly used to improve flexibility, instrument-assisted soft tissue mobilization (IASTM) has recently gained popularity. However, no studies in the current literature have compared the acute effects of these three methods in individuals with hamstring tightness. This study aims to compare the acute effects of stretching, myofascial release, and IASTM in individuals diagnosed with hamstring tightness (defined as \<65° of hip flexion in the straight leg raise test without neurological findings).
