The purpose of this study is to investigate the risk factors of metabolic syndrome, cardiorespiratory fitness, knee isokinetic function, and osteoarthritis index inpatients with knee osteoarthritis women. Subjects were divided into the exercise group (n=9, aged 60.89±5.06), and the control groups (n=8, aged 61.25±1.91). Aquatic exercise was performed for 12 weeks, 3 times a week, 60 min a day. The changes of metabolic syndrome risk factors, cardiorespiratory fitness, knee isokinetic function, and WOMAC index (Western Ontario and McMaster University osteoarthritis index) were measured and analyzed at pre- and postex-ercise program for verifying exercise effectiveness. As a result, fasting blood glucose (P<0.05), glycosylated hemoglobin (P<0.01), and triglyceride (P<0.05) were significantly decreased in the risk factors of metabolic syndrome. The maximum oxygen uptake in cardiorespiratory fitness was not significantly different. The left and right extensor muscles of knee isokinetic function increased significantly (P<0.01, P<0.01, respectively). There was no significant difference in flexor muscles. Osteoarthritis index was significantly improved in stiffness (P<0.01) and physical function (P<0.05). In conclusion, aquatic exercise can be regarded as an effective exercise program for managing metabolic syndrome risk factors, increasing muscle function, and improving osteoarthritis index in patients with osteoarthritis of the knee
