Older women with type 2 diabetes who combined vitamin D supplementation with circuit training saw greater benefits than those who simply exercised in a recent study. The 52 women were recruited by researchers at Korea's Kyung Hee University. Each was assigned to one of four groups: circuit training, which involves moving between exercises in a defined sequence, alone; vitamin D supplementation alone; training and supplementation combined; and neither (control group). All the participants were deficient in vitamin D at the beginning of the study. After 12 weeks, women in the training/supplementation group showed the greatest improvements in insulin resistance (in which cells don't respond to insulin properly), body composition, especially reduced abdominal fat, and blood lipids, including total LDL and HDL cholesterol as well as triglycerides. Results were published in the Journal of Exercise Nutrition and Biochemistry. Vitamin D May Enhance Exercise Effects in Diabetics Abby's Magazine - May/June 2015 | Page 43
