Recruitment of muscle fibers

Recruitment of muscle fibers refers to how our body activates muscle cells to generate force during physical activity. When you start an exercise, your nervous system signals a few muscle fibers to contract. As the demand increases—like lifting heavier weights—more fibers are recruited to handle the load. This process helps optimize strength and endurance. Different types of fibers are involved: fast-twitch fibers work for quick bursts of energy, while slow-twitch fibers are suited for endurance. Efficient recruitment allows for better performance and adaptation, helping muscles grow stronger and improving overall physical capability.
