Calf Injury
Muscle pulls and tears commonly occur in the major muscles of the calf, the gastronemius and the soleus.
These muscles make up the large bulge in the back of the lower leg and are responsible for lifting the heel and driving you forward as you run.
A calf strain can be caused by:
- Stretching the calf muscles beyond the amount of tension that they can withstand
- Suddenly putting stress on the calf muscles when they are not ready for the stress
- Using the calf muscles too much on a certain day
- A direct blow to the calf muscles
