effects of eccentric and concentric exercises on some functional activity indexes of patients with diabetes type 2

background around 7% of the world population have diabetes and suffer from its extensive complications. many studies are conducted on the positive effects of aerobic and resistance exercises on the reduction of body performances, but considering the available references, no specific study is conducted on the effect of eccentric exercises on patients with diabetes. objectives the current study aimed to evaluate and compare the effects of eccentric and concentric exercises on some functional activity indexes in patients with diabetes type 2. patients and methods twenty eight patients with diabetes type 2 were randomly divided into two groups of eccentric and concentric exercises using treadmill. six minute walking and time up and go tests were performed before and after control and intervention periods. results results of the current study showed that eccentric and concentric exercises significantly improved the two mentioned functional indexes. however, eccentric exercises in comparison with concentric exercises significantly improved the results of six minute walking test (p < 0.0001). also, in the time up and go test, no significant difference was observed between the groups. conclusions results of the current study showed that the eccentric exercises improve the functional activity of patients with diabetes.
