Healthspan Part 4: Exercise Benefits in Skeletal Muscle Mass & Strength

Skeletal muscle quality, which includes both muscle mass (the number and size of muscle fibers) and muscle strength (force production and contractility), is critical for maintaining mobility, balance, and motor coordination. Loss of muscle mass and strength can significantly impact healthspan, reducing the overall quality of life. Age-related loss of skeletal muscle mass, known as sarcopenia, along with increased frailty, is one of the leading causes of morbidity among the aging population, affecting over 10% of individuals over 60 years of age. However, regular exercise can significantly delay or even prevent the loss of muscle mass, thereby extending healthspan.
