Exercise can cause which of the following reactions in the aging musculoskeletal system?

The choice that highlights increased flexibility and increased muscle tone is grounded in the understanding of how regular exercise positively influences the aging musculoskeletal system. As individuals age, they often experience a natural decline in muscle mass and flexibility; however, engaging in consistent resistance and flexibility training can counteract these effects.

Regular exercise, particularly strength training and stretching, leads to several beneficial adaptations in muscle and joint function. Increased muscle tone refers to improved neuromuscular efficiency and muscle strength, which can enhance overall stability and performance in daily activities. Alongside this, flexibility improves through the elongation of muscles and connective tissues, leading to a greater range of motion in the joints.

Furthermore, the aging musculoskeletal system can benefit from the anti-inflammatory effects of regular physical activity, which helps reduce stiffness and discomfort. Therefore, the response that emphasizes increased flexibility and increased muscle tone accurately reflects the positive outcomes exercise can provide to older adults.
