The Effects of Six Weeks Strengthening exercise on Some Biomechanical Properties of Knee Joint in Type 2 Diabetic Patients

Decreased muscle strength in the lower extremities is one of the disorders caused by type 2 diabetes. The purpose of this study was to investigate the effect of six weeks strengthening training on some biomechanical parameters of knee joint in type 2 diabetic patients. 24 patients with type 2 diabetes participated in the study and were divided in control group (N=12) and exercise group (N=12). Before and after six weeks of strengthening exercise program, research variables were measured by isokinetic dynamometer. The results showed that there were significant differences in concentric peak torque of knee flexion and extension and time to concentric peak torque of knee flexion and extension between two groups. It seems that strengthening exercise can improve the power generation capacity and neuromuscular function in patients with type 2 diabetes by increasing knee concentric peak torque and decreasing time to concentric peak torque.
