The Zoomer Report: Mice and Exercise
It works for mice, and researchers at McMaster University figure it will work for humans too. Their study in the Proceedings of the National Academy of Sciences found that exercising on a treadmill for 45 minutes three times a week warded off the effects of premature aging. The mice in the study were genetically engineered to age faster. But those who had the exercise training looked as young as healthy mice, and had almost 100 per cent protection from brain and muscle atrophy, anemia, heart enlargement, hair loss and greying of the fur. On the other hand, the sedentary mice were balding, greying, physically inactive, socially isolated and less fertile.
The researchers say the exercise worked better than other attempts to stop aging in mice through drugs and caloric reduction. They believe this shows that exercise truly is the fountain of youth and the recipe for healthy aging. The problem is that it is most people find it difficult. The researchers hope these findings will give them an extra push to get off the couch.
