All physical activity is good for people with diabetes, but different types of exercise can present different benefits. The two main types of exercise are aerobic exercise and resistance exercise.In this article we will answer the question, what is resistance exercise.
Aerobic exercise works your lungs and heart, and helps carry oxygen around the body. Resistance exercise works to build muscle strength, together with bone strength and bone density. It has also been shown to be a valuable tool in maintaining blood glucose targets, by improving glucose regulation. Studies also show regular resistance exercise can help to increase levels of lipoprotein – the ‘good’ and desirable cholesterol.
Resistance exercise may also provide the necessary emotional boost for those who need to see results quickly in order to remain motivated. Results are usually seen more quickly than with aerobic exercise, with muscles often become visibly more toned within a short time.
What exactly is resistance exercise?
Resistance exercise forces the muscles to work repeatedly to overcome a resistance force. Weight lifting is a common resistance exercise, but it is not the only one.
Some exercises like weight lifting may use external resistance force from dumbbells, weight machines or resistance bands. Other exercises use the body’s own weight as the force. You may know this last form of resistance exercise as ‘calisthenics’. Exercises that fall in this group, using the body’s own weight, include push-ups, sit-ups, and abdominal curls.
Resistance exercise recommendations
The Canadian Physical Activity Guidelines recommend resistance exercise at least two days a week for all individuals. For people with diabetes, Diabetes Canada suggests a goal of three times a week.
Diabetes Canada stresses the need to first get instruction from a qualified exercise specialist. If your family member or friend has type 1 diabetes or has type 2 diabetes and uses insulin, it is also very important to check with the diabetes team before starting any new form of physical activity. Insulin adjustments may be required.
When it comes to specific exercises, Diabetes Canada recommends that at each resistance exercise session, most of the body’s major muscles should be worked with 8 to 10 different exercises. Each exercise should be repeated 10 to 15 times at light to moderate intensity. As your body becomes used to this exercise routine, the routine can be repeated two or three times a session.
As always, people with diabetes should put safety first and stop exercising if there is excessive shortness of breath or any chest pain. If this occurs, a doctor should be consulted.
Your family member or friend with diabetes should also remember to monitor blood glucose before, during and after exercising. This can be a great motivator, since levels are often immediately improved by the exercise.
And finally, people with diabetes who exercise in a gym should wear a MedicAlert® bracelet or necklace.
