Compare and contrast the benefits and effects of running and walking.

Answer:

Both running and walking are aerobic activities that can improve heart and lung fitness, support overall health, and help manage stress. Running is more vigorous, so it generally burns more calories in less time, but it places more impact on the joints and may carry a greater risk of injury. Walking is lower impact and easier for many people to sustain, though it may take longer to achieve a similar workout. The best choice depends on a person's goals, fitness, and abilities.
