Method: The participants, including 30 college students (age 19.87 ± 1.68 yrs, height 167.45 ± 7.20 cm, weight 63.16 ± 11.60 kg), received incremental maximal exercise to exhaustion to obtain the heart rate maximal. According to the balance way of order, the participants accepted three kinds of aerobic exercise (70% HRR HRC with treadmill, 70% HRR HRC fixed frequency 50rpm with elliptical machine and 40rpm fixed frequency with Core X) respectively for 30 minutes. After 30 minutes of rest after exercise, Ultrasonic Doppler Flow Detector was used to measure pulse wave velocity. Data was progressed by One-way ANOVA to compare the difference among the effects of 3 aerobic exercise on the carotid-femoral (cf), brachial-ankle (ba) and femoral-ankle (fa) PWV. The significant level was set at α=.05. Result: There were no significant differences on pulse wave velocity of resting and after aerobic exercise from cfPWV, baPWV and faPWV cfPWV after elliptical machines and Core X aerobic exercise were significant different (p<.05). Both baPWV and faPWV after aerobic exercise of treadmills, elliptical machines and Core X had no significant difference. Conclusion: Central arterial compliance was indices with elliptical aerobic training. The effect of arterial compliance with Core X and treadmill aerobic exercise that no difference.
