Final answer:
The exercise types that can prevent contractures and muscle atrophy are range-of-motion, strengthening, and weight-bearing exercises. Each contributes to keeping muscles and joints healthy and functional, and the combination of these exercises can prevent atrophy and increase stability.
Step-by-step explanation:
The types of exercises that can help prevent contractures and muscle atrophy are (A) Range-of-motion exercises, (B) Strengthening exercises, and (C) Weight-bearing exercises. Therefore, the correct answer is (D) All of the above. Range-of-motion exercises ensure that muscles and joints maintain flexibility and are often used in rehabilitation settings. Strengthening exercises, including anaerobic activities such as weight training, help build muscle mass and prevent muscle atrophy. Weight-bearing exercises help maintain bone density and support musculoskeletal health.
Each type of exercise contributes uniquely to muscular health. Flexibility exercises, like stretching, improve muscle and joint range of motion which is crucial for preventing stiffness and contractures. Regular stretching and flexibility work, such as yoga or tai chi, can thus help avoid activity-related injuries. Strengthening and weight-bearing exercises not only build muscle but also contribute to joint stabilization, which can reduce joint stress and help with conditions like osteoarthritis. For example, swimming and biking are recommended for their low impact on joints while still building strength and endurance.
