Final answer:
Resistance training is vital for the overall health of the musculoskeletal and cardiovascular systems. It improves muscle strength, bone density, and heart efficiency, while also bolstering the immune system by releasing myokines with anti-inflammatory effects. Option a and b are correct answers.
Step-by-step explanation:
Health benefits of resistance training are vital for the overall health of several body systems, specifically the musculoskeletal system. Resistance training, which includes anaerobic exercises like weight training, increases muscle strength and bone density. This type of exercise is crucial in maintaining and improving the health and strength of muscles and bones.
Moreover, resistance training has benefits for the cardiovascular system as well. It helps to lower the risk factors associated with cardiovascular disease such as hypertension, bad cholesterol, and body weight, by increasing good cholesterol and insulin sensitivity which, in turn, improves the mechanical efficiency of the heart. Thus, by enhancing cardiovascular and muscular fitness, resistance training can also help in improving overall physical health and exercise tolerance.
Additionally, the benefits for the immune system should not be overlooked. Regular physical exercise, including resistance training, contributes to a more robust immune system by lowering inflammation and reducing the incidence of various inflammatory diseases. This is partly due to the anti-inflammatory effects of myokines, which are hormones released by contracting muscles.
