Age affects flexibility, as connective tissues often become stiffer and less elastic with the aging process. This decrease in flexibility can be attributed to changes in muscle mass, physical activity levels, and collagen structure within tissues. As individuals age, they may experience decreased range of motion and increased risk of injury during physical activities. To counteract these effects, incorporating regular stretching and mobility exercises into daily routines is essential. Maintaining flexibility through progressive training can enhance functional movement, contributing to better quality of life and overall physical health as one ages.
