Document Summary
To achieve health benefits, adults aged 18-64 years should accumulate at least 150 minutes of moderate to vigorous intensity aerobic physical activity per week, in bouts of 10 minutes or more. It is also beneficial to add muscle and bone strengthening activities using major muscle groups, at least. More physical activity provides greater health benefits. Activity for at least 150 minutes/week reduces risk of: premature death, heart disease, stroke, high blood pressure, certain types of cancer, type 2 diabetes, osteoporosis, overweight and obesity. Physical activity can also lead to improved fitness, strength, mental health (morale and self-esteem), stress management, sleep, relief from depression, anxiety reduction, and resistance to mental fatigue. When you are studying, it helps to take a break and exercise because it helps you learn more. Atp generation can be aerobic or anaerobic. Aerobic metabolism is far more efficient, but it takes time to deliver oxygen to muscles.
