Final answer:
The statement is true: regular strength training can increase muscle mass, improve bone density, and enhance joint flexibility, counteracting the effects of aging such as muscle atrophy and bone loss.
Step-by-step explanation:
The statement that strength training can help reverse the trend of natural muscle mass decrease with age, increase bone density, and improve joint flexibility is true. As we age, a condition called sarcopenia leads to muscle atrophy, which can impact balance, posture, and overall strength. However, strength training contributes to increased muscle mass, greater bone density, and improved flexibility and stability.
Resistance training is particularly effective for not only maintaining muscle mass but also increasing bone density, which is important for preventing osteoporosis. In addition, regular physical activity can greatly benefit joint health by maintaining strength and flexibility, which helps protect and stabilize the joints, thereby reducing the symptoms of arthritis.
Overall, regular engagement in resistance and strength training exercises is essential for promoting healthier aging, preserving muscle and bone health, and ensuring joint flexibility.
