Muscle Fiber Recruitment

Muscle fiber recruitment refers to the process your body uses to activate different types of muscle fibers during movement. When you start a gentle activity, your body initially activates slow-twitch fibers that are endurance-oriented. For more intense efforts, it recruits fast-twitch fibers that generate more power but tire quickly. As the demand increases, more fibers are engaged to produce force. This sequential activation ensures efficient use of energy and helps tailor muscle output to the activity's intensity, allowing for smooth, controlled movements and strength development across different physical tasks.
