Discuss how aerobic exercise and strength training help prevent and treat diabetes?
What will be an ideal response?
ANSWER: Aerobic exercise helps prevent type 2 diabetes. The preventive effect is attributed to less body fat and to better sugar and fat metabolism resulting from the regular exercise program. At 3,500 calories of energy expenditure per week through exercise, the risk is cut in half versus that of a sedentary lifestyle.
Strength training is also increasingly used to help prevent and treat diabetes. During strength training, muscles use glucose exclusively to perform their work. Following a good strength-training workout, muscles will use more glucose during the next 48 hours. And as muscle mass increases with training, so does the body's ability to utilize blood glucose. The key to increase and maintain proper insulin sensitivity is regularity of the aerobic and strength-training programs. Failure to maintain habitual physical activity voids the benefits.
