Exercise, however modest, found progressively beneficial to the elderly

Even exercise of short duration and low intensity has life expectancy benefits for the elderly. Such conclusions have been well examined in the general population, where a recommended exercise program of 30 minutes at least five days a week (or 150 minutes per week) has been shown to reduce the average risk of death by 30%. However, such a correlation between the level of physical activity and risk of death has not been so clearly determined in the elderly. Indeed, most physical activity guidelines are the same for the middle-aged adults as for the elderly, even though it is estimated that over 60% of the elderly are unable to achieve this same level of exercise.
