Human muscles are incredibly adaptable. For instance, different types of muscle fibers—slow-twitch and fast-twitch—serve different functions. Slow-twitch fibers are more resistant to fatigue and are used for endurance activities, like long-distance running. Fast-twitch fibers are better for quick, powerful movements, like sprinting or weightlifting. The composition of muscle fibers can change based on training and activity, highlighting the body’s ability to adapt to various physical demands.
