Recommended levels of physical activity for adults aged 65 and above
Older adults should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity.
Aerobic activity should be performed in bouts of at least 10 minutes duration.
For additional health benefits, older adults should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate-and vigorous-intensity activity.
Older adults, with poor mobility, should perform physical activity to enhance balance and prevent falls on 3 or more days per week.
Muscle-strengthening activities, involving major muscle groups, should be done on 2 or more days a week.
When older adults cannot do the recommended amounts of physical activity due to health conditions, they should be as physically active as their abilities and conditions allow.
Strength training may lead to modest increase aerobic capacity in older adults (Liu and Latham 2009)
Note: training should be at least 55-65% of maximum heart rate for 20-60 minutes for 3-5 days per week to increase cardiorespiratory fitness (ACSM 1998)
