Researchers are increasingly examining muscle quality; the strength and function of muscle relative to its size, as a key factor in physical performance and healthy aging. Studies suggest muscle quality declines earlier and faster than muscle mass in many individuals.

This shift in perspective has important implications for exercise programming. Resistance training designed to improve neuromuscular coordination, power and functional strength may help preserve muscle quality and maintain independence across the lifespan.
