The phenomenon of hamstring atrophy requires active functional exercises, especially functional exercises for flexion and extension of the legs and joints, and increasing muscle tone to enhance muscle strength, thus relieving the phenomenon of hamstring atrophy. Functional exercises are the main treatment method and have an extremely important role in relieving the phenomenon of atrophy. Leg tendon atrophy is usually caused by long-term activity restriction, local fractures, and trauma. Active functional exercise can promote local atrophy recovery and restore the function of the joint. Functional exercise requires other treatments to promote the recovery of atrophy, such as physical therapy and medication can increase the effectiveness of the treatment and have a very important role in restoring the function of the joint.
