Recommendations for aerobic exercise in patients with type 2 diabetes
- to improve glycemic control, assist with weight maintenance, and reduce risk of CVD:
- at least 150 min/week of moderate intensity aerobic physical activity (40-60% of VO2max or 50-70% of maximum heart rate)
- and/or at least 90 minutes per week of vigorous aerobic exercise (>60% VO2max or >70% maximum heart rate)
- the physical activity should be distributed over at least 3 days/week and with no more than 2 consecutive days without physical activity
- performing at least 4 or more hours per week of moderate to vigorous aerobic and/or reisistance exercise is associated with greater CVD risk reduction than lower volumes of activity
- for long-term maintenance of major weight loss (30 lb) larger volumes of exercise (7 hours of moderate or vigorous aerobic physical activity may be helpful
- levels of evidence according to American Diabetes Association standards
- A for improved glycemic control
- B for CVD prevention and B for long-term maintenance of major weight loss
Recommendations for resistance exercise for patients with type 2 diabetes
- in the absence of contraindications, people with type 2 diabetes should be encouraged to perform resistance exercise three times per week
- workouts should include all major muscle groups
- prgress to 3 sets of 8-10 repetitions at a weight that cannot be lifted more than 8-10 times
- level of evidence: A
Recommendations for flexibility exercise: Insufficient evidence to recommend for or against flexibility exercise as a routine part of the exercise prescription.
- Recommendations for flexibility exercise
