How are quadriceps used in running?

The quadriceps, a group of four muscles located at the front of the thigh, play a crucial role in running by facilitating knee extension during the push-off phase of the gait cycle. They help stabilize the knee joint upon landing, absorbing impact and maintaining balance. Additionally, strong quadriceps contribute to overall running efficiency and speed by assisting in propelling the body forward with each stride. Proper strength and conditioning of the quadriceps can enhance running performance and reduce the risk of injury.
