Sprinter – Anatomical Illustration

Medical illustration of sprinter in action

The image emphasizes the skeletal muscles and their role in movement. Sprinting uses the same muscles as running, but requires that they are considerably more limber for short bursts of speed while avoiding injury.

The quadriceps muscles raise the leg and propel the runner forward. They work in conjunction with the hamstring muscles as the most important coordinating pair for sprints.

The hamstrings are the antagonist muscles at the back of the thighs that pull the leg back so that the sprinter has the force to push off the ground quickly from the calves.

The hip flexor muscles are crucial to sprinters, because nimble hip flexors allow legs to move quickly and in concert with the rest of the body’s speed of propulsion.

The calves comprise two muscles: the gastrocnemius and soleus. These muscles are vital to sprinting more than regular running, because the muscles of the calves control foot flexion when running.
