Do the calves play a role in insulin sensitivity? The gastrocnemius muscle, the prominent superficial muscle of the posterior calf, is often appreciated primarily for its mechanical contributions to locomotion. However, emerging research demonstrates that it also plays a meaningful role in systemic glucose homeostasis and insulin sensitivity.
Although the calves represent a relatively small fraction of total skeletal muscle mass, its frequent recruitment during daily activities and its unique fiber-type composition make it a noteworthy contributor to metabolic health. This article looks at the calf – insulin axis, and reviews the recent science tying the two together.
