Exercise to Protect Aging Bodies — and Brains
Posted by: | CommentsWe all know that exercise is good for you. Staying physically active helps keep your heart healthy and your muscles strong, and in cancer patients it has even been shown to ward off relapse.
Now a series of independently conducted studies on the effects of exercise in healthy older adults, published on Monday in the Archives of Internal Medicine, confirms that logging time at the gym not only helps maintain good health but may even prevent the onset of chronic diseases, such as heart disease, osteoarthritis and dementia.
In one surprising trial, researchers led by Dr. Teresa Liu-Ambrose at the University of British Columbia randomly assigned 155 aging women to three separate groups and directly compared the cognitive effects of two types of exercise: resistance training, done once or twice weekly, in which participants worked out with free weights and weight machines and did squats and lunges, versus toning and balance exercises, which participants did twice a week.

To Get The Most Out Of Exercise, Eat Fewer Carbs
Posted by: | CommentsWriting in the Journal of Applied Physiology, researchers say that Many of the health benefits of aerobic exercise are due to the most recent exercise session, and the nature of these benefits can be greatly affected by the food we eat afterwards .
Specifically, the study found that exercise enhanced insulin sensitivity, particularly when meals eaten after the exercise session contained relatively low carbohydrate content. Enhanced insulin sensitivity means that it is easier for the body to take up sugar from the blood stream into tissues like muscles, where it can be stored or used as fuel. Impaired insulin sensitivity (i.e., “insulin resistance”) is a hallmark of Type II diabetes, as well as being a major risk factor for other chronic diseases, such as heart disease.
