Final answer:
Aerobic exercise provides many health benefits such as improving heart's pumping efficiency, decreasing resting heart rate, bone mass enhancement with aging, and augmenting lung ventilation by dilating bronchioles. However, it doesn't decrease the risk of musculoskeletal injury or dehydration.
Step-by-step explanation:
When discussing the benefits of regular aerobic exercise, there are several key points to highlight. Here are some accurate options:
- Improves the pumping action of the heart: This makes the heart more efficient in delivering oxygen and nutrients to the body's tissues.
- Decreases heart rate: Over time, regular aerobic exercise can lower your resting heart rate because your heart becomes more efficient in its function.
- Improves bone mass with aging: Weight-bearing aerobic exercises, like walking or running, can decrease the risk of osteoporosis later in life.
- Dilates bronchioles to increase ventilation: Regular aerobic exercise increases lung capacity, helping to improve overall respiratory health.
However, aerobic exercise does not necessarily decrease the risk of musculoskeletal injury or dehydration. Most often, risks for injuries or hydration issues can increase with exercise if not done properly or without adequate hydration.
