The most active leg muscle during running is the tibialis anterior, a strip of sinew which runs down the shin to the inside edge of the foot and pulls the foot inward and upward.
During running, the tibialis anterior contracts forcefully about twice as often as any of the other four muscles, so it is probably the muscle most prone to fatigue. As it becomes tired, the risk of shin splints and stress fractures is likely to rise, as does the amount of pronation occurring at the ankle joint (excessive pronation has been linked to a variety of running problems, including knee injuries).
Thus, it is critical for athletes to make their tibialis anterior muscles as strong and fatigue proof as possible.
Some of the ideas to make the tibialis anterior muscle stronger is,
- Deeping the lower leg in ice bath after running
- Soft massage
- Stretching the lower leg
- Doing squats and calf raises
