  1. The Effect of Exercise on Glycemic Control in Diabetics

    Type 2 diabetes is a growing problem not only in the United States, but worldwide. A Spanish study published in Nutrición Hospitalaria searched the literature looking for studies on exercise and diabetes. They found that aerobic exercise, resistance exercise, a combination of the two, and high intensity interval training all resulted in improving glycemic control. While the combination of aerobic and resistance offered the most benefit, they found that having a structured format that included a prescribed frequency, volume and intensity was essential. Consistently swimming with a masters swimming club would offer all of these benefits. Swimming on your own will as well, if you're consistent and give yourself a structured workout.
  2. Distribution of Body Fat

    A new study looked at how exercise affects the distribution of body fat. The study in Obesity examined data from 10,500 healthy US men in the Health Professionals Follow-up Study. Moderate to vigorous aerobic activity was most strongly associated with body weight change. Interestingly, only weight training at 20 minutes a day resulted in a significant decrease in waist circumference. Both an increased waist to hip ratio and an increased waist circumference are associated with an increased risk for cardiovascular disease and diabetes. Men should have a waist to hip ratio no larger than .90 and women no larger than .85. Waist circumference should be under 40 inches in men and 35 inches in females. Belly fat or abdominal fat is "angry" or inflammatory fat.
  3. Staying Young

    The New York Times reported on an article that appeared recently in The Journal of Physiology that looked at the influence that being physically active has on aging. The researchers evaluated 85 men and 41 women between the ages of 55 and 79 who bicycled regularly. The men had to be able to ride at least 62 miles in 6.5 hours and women 37 miles in 5.5 hours. The researchers compared the testing results against the data from previous studies on older people and against each other. Not surprisingly to Masters swimmers, the cyclists did not show their age in many parameters: level of balance, reflexes, metabolic health, and memory ability. Many of these are measures that reflect how well an individual will function in the world. With all this good news there are still some facets of aging that are inevitable: a decrease in aerobic capacity, endurance and strength with advancing age. However, the athletes still showed less decline than their sedentary counterparts.
