T/F
Skeletal muscle of older people is more easily damaged with the loading that occurs during training compared with skeletal muscle of younger adults.
T
T/F
Aging collagen decreased cross-links between molecules, increasing the mechanical stability of collagen but also contributing to increased tissue stiffness.
F
T/F
Tendons exhibit a lower metabolic activity associated with aging that has implications for injury and healing in the aging population.
