How does age affect flexibility?

Flexibility typically decreases with age due to several physiological changes in the body. As individuals age, there are significant alterations in muscle and connective tissue properties. Collagen fibers, which contribute to the structure and elasticity of tissues, become stiffer and less pliable. Additionally, there may be a reduction in the production of synovial fluid, which lubricates the joints and can lead to decreased joint mobility.

With age, the muscles themselves can also lose elasticity and strength, leading to reduced range of motion. The overall decrease in physical activity among older adults can further contribute to deterioration in flexibility as the lack of regular stretching and movement can cause shortening of muscles and tightening of connective tissues.

This understanding emphasizes the importance of incorporating flexibility training into fitness regimens, particularly for older adults, to maintain mobility and reduce the risk of injuries. By recognizing these changes, trainers and individuals can take proactive steps to combat the decline in flexibility associated with aging.
