The purpose of this study was to compare and analyse cardiovascular risk factors and cardiorespiratory capacity in the elderly by exercise career in badminton. Total more than sixty-year-old twenty seven female subjects(nine with no experience in exercise in latest five years; nine experienced in less than three years of regular badminton exercise; nine experienced in more than five years of regular badminton exercise) were participated in this study. Blood collection and Graded Exercise Test(GXT) were conducted to measure the variables above. 1. In cardiorespiratory capacity, Resting Systolic Blood Pressure(RSBP) is significantly lower in long period exercise group than in control group(p<.05). There is no significant difference in Resting Diastole Blood Pressure(RDBP). VO2max is significantly higher in long period exercise group than in control group(p<.05). MET is significantly higher in long period exercise group than in control group and in short period exercise group(p<.01, p<.01). Heart Rate Recovery(HRR) on 1 minute and 2 minute is significantly higher in long period exercise group than in control group and in short period exercise group(p<.01, p<.01). 2. In body composition, there is no significant difference in Body Mass Index(BMI). Waist Hip Ratio(WHR) is significantly lower in long period exercise group than in control group than(p<.01). There is no significant difference in Body Fat(BF). 3. In lipid profile and hs-CRP, there is no significant difference in TC, TG, HDL-C, LDL-C and hs-CRP. In conclusion, the result revealed that cardiorespiratory capacity is enhanced and cardiovascular risk factors were reduced by badminton exercise. Therefore, it is suggested that the badminton exercise could prevent cardiovascular disease of the elderly. In addition, the study showed that it is necessary to start to exercise earlier than the period when the cardiovascular disease is easy to appear.
