  1. Role of Biceps: The Biceps muscle is primarily responsible for the flexion of the elbow, which occurs during the running motion when the arm is drawn back and forth.

  2. Role of Hamstrings: The Hamstrings play a crucial role in knee flexion and hip extension, which aids in propelling the body forward while running.

  3. Role of Gastrocnemius: The Gastrocnemius muscle is key for plantar flexion of the foot at the ankle joint, which provides the push-off needed during running.
