Potential health benefits and risks of cardiorespiratory activity?
amount of physical activity
will not prepare you for running a marathon, but it can
improve your overall health and can result in some cardiovascular
improvements. The ACSM and CDC recommend
that if you want to improve your cardiorespiratory fitness
even more, you need to perform vigorous physical activities
(for example, jogging or running, walking hills, circuit
weight training, singles tennis) at least 3 days per week for
at least 20 minutes at a time; if losing weight is your goal,
you need to add to your daily routine moderate to vigorous
exercise for 60 to 90 minutes.
