Age affects the body's ability to recover after exercise as metabolic processes slow down over time. Muscle fibers may repair slower, and joint flexibility can decrease, leading to prolonged soreness. Older adults often experience reduced blood flow and hormonal changes that further affect recovery times. Additionally, the risk of injury may increase due to diminished muscle mass and strength. It's essential for older individuals to adapt their fitness regimens to include adequate rest and recovery strategies to maintain health and fitness levels.
