What is the effect of bilateral asymmetry in the lower leg muscles on muscle biomechanics in healthy individuals?

We will explore how natural anatomical differences between the left and right lower-leg muscles may influence muscle function in healthy adults aged 18 to 65. We focus specifically on the soleus, tibialis anterior, and the medial and lateral heads of the gastrocnemius, as these muscles play an essential role in posture, locomotion, and overall lower-limb performance. In this research project, we aim to understand how structural characteristics such as pennation angles, fascicle lengths, muscle volume, and physiological cross-sectional area can differ between both legs, and how these differences may affect muscle activity. To investigate these relationships, we use ultrasound imaging to carefully measure and quantify any structural asymmetry. Additionally, we collect electromyography data to evaluate how the muscles respond and activate during gait. By combining these methods, our goal is to better understand how anatomical asymmetry affects muscle biomechanics in healthy individuals. We hope that our findings will provide clearer insight into how natural variations in muscle structure influence movement and internal muscle function. In the long term, this knowledge may support more targeted assessment, training strategies, and rehabilitation approaches for both athletes and the general population.
