In general, aerobic exercise decreases arterial stiffness and blood pressure, but resistance training increases them. We tested the hypothesis that combined exercise(aerobic and resistance training) may alter the cardiovascular risk factors and arterial stiffness(PWV). A total of thirty healthy women(age, 44.4±5.2yr) arranged into exercise group(n=15) and control group(n=15). Combined exercise program composited by two part, which aerobic training walk and jog during about 30min on treadmill, and resistance training consist of 5 machine exercise(squat, bench press, sit up, lat pull down,knee extension) performing 10 reps, 3sets, respectively. After combined training during 8 weeks, left and right baPWVs were decreased from 1279.2±211.0 cm/sec to 1229.8±168.2 cm/sec and from 1284.6±203.2 cm/sec to 1249.9±171.8 cm/sec, respectively, although statistically not significant. In conclusion, these results suggested that combined exercise during 8 weeks can reduce the decrease or at least no increasement of arterial stiffness in the middled-aged women. Further studies using larger sample size will be required to clarify the precise relationship between combined exercise and arterial stiffness
