Short-term Effect of Crossfit on Cardiovascular Disease Risk Factors and Fitness Components in Obese Middle-aged Men. The Journal of Kinesiology, 2017, 19(3): 15-25. [PURPOSE] The purpose of this study was to com-pared cardiovascular disease risk factors and fitness components in obese middle aged men after Crossfit exercise in 2 weeks. [METHODS] All subjects were obese and middle aged men. Cardiovascular disease risk factors (body fat percent, waist cir-cumference, body mass index, blood pressure, total-cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, fasting glucose), and fitness components (muscle strength, muscle endurance, agility, flexibility) were measured and compared before and after 2 weeks. [RESULTS] First, waist circumference was significantly improved and diastolic blood pressure was significantly dif-ferent after 2 weeks. Second, muscle endurance, agility, and flexibility were significantly improved after 2 weeks. [CONCLUSIONS] These results implies that short term participant of Crossfit exercise is time-efficient exercise to improve health and fitness in obese middle aged men.
