30 minutes for exercise daily lowers death risk

LONDON: Just 30 minutes of physical activity six days a week is linked to a 40 per cent lower risk of death from any cause among the elderly, a new research shows.

Boosting physical activity levels among the seniors seems to be as good for health as giving up smoking, the findings suggest.

Based on the analysis of 15,000 men, it indicated that less than an hour a week of light physical activity was not associated with any meaningful reduction in risk of death from any cause.

But more than an hour was linked to a 32 per cent to 56 per cent lower risk.

Less than an hour of vigorous physical activity, on the other hand, was linked to a reduction in risk of between 23 per cent and 37 per cent for cardiovascular disease and death from any cause.

The more time spent doing vigorous exercise the lower the risk seemed to be, falling by between 36 per cent and 49 per cent.

"Men who are regularly engaged in moderate to vigorous physical activity during their leisure time lived five years longer, on average, than those who were classified as sedentary (watching TV or reading)," the authors wrote.

More effort should go into encouraging elderly men to become more physically active, the researchers emphasised in the paper appeared in the British Journal of Sports Medicine.
