How can participation in physical activity lead to improved sleep patterns?
answer
Participation in physical activity can relieve tension and allow the body to relax more readily. This leads to an ability to fall asleep more quickly, a better quality of sleep, and improved length of sleep.
question
Compare and contrast aerobic physical activity with anaerobic physical activity.
answer
Aerobic physical activity is done for longer time periods than anaerobic physical activity. Aerobic physical activity is better for the cardiovascular system than it is for strength endurance, while anaerobic physical activity is better at building strength endurance than it is at increasing cardiorespiratory fitness. Any activity done for longer than two minutes becomes an aerobic activity as the body adjusts to the activity and begins to supply sufficient oxygen to the muscles.
question
Explain how regular participation in physical activity can increase life expectancy.
answer
Regular participation in physical activity can increase life expectancy by reducing the risk of developing certain diseases. Regular physical activity can reduce the risk of developing certain types of cancers, osteoporosis, cardiovascular disease, and obesity. Reducing the risk of developing these diseases can lead to a greater life expectancy.
