Synergistic yet different: Rethinking the gastrocnemii as two functionally distinct muscles AbstractΒ The human medial and lateral gastrocnemius muscles play important roles in gait, standing balance, and numerous sports activities. Because they share

Synergistic yet different: Rethinking the gastrocnemii as two functionally distinct muscles.

In this preprint perspective article, @francoishug.bsky.social and I delve into the biomechanics, anatomy, neural control, and function of the gastrocnemius muscles, two important calf muscles.
