The seated calf raise and the muscles involved are very important in all running and jumping type activities. In addition, it should be emphasized that the seated calf raise is especially important for all long distance runners and walkers. The soleus has great staying power and the more you can develop it, the longer it will enable you to continue an activity.
The gastrocnemius is usually composed of mainly white fibers or an equal amount of white and red fibers. Thus, the soleus can take over in many cases when the gastrocnemius becomes fatigued. For this reason it is very important that the soleus be developed separately and together with the gastrocnemius. It should also be noted that the soleus is most important for bodybuilders for giving width to the calf muscles.
