This study is in order to observe the changes of arterial and muscle stiffness after iso-kinetic single leg exercise and whole body vibration application. In a cross-over design, 9 young (19.5±1.4years) healthy males were assigned to whole body vibration (WBV) treatment group and control (complete rest) group with a week interval. Each Subject conducted iso-kinetic knee flexion and extension exercise by dominant leg at180°/sec, 10 bouts, and 10 sets (Biodex system 4, Medical System Inc, USA). The WBV session consisted of 10 sets of vibration (frequency, 26 Hz) for 60s with 60s of rest between sets. Cardio-ankle vascular index (CAVI) and ankle-brachial index (ABI), as index of arterial stiffness, were measured by VaSera CAVI instrument (Fukuda Denshi Co., Ltd., Tokyo, Japan) before, right after exercise and recovery 20min. In order to measure the mechanical properties like muscle stiffness and elasticity, MyotonPro (Myoton AS, Tallinn, Estonia) was applied to muscle belly of rectus femoris at the same time point. From the Myoton measurement, Three indexes (Frequency, Logarithmic Decrement and Dynamic Stiffness) were obtained. The results are as follows: 1. No significant difference in rectus femoris muscle and arterial stiffness index were found between WBV and control group at all the time point. 2. ABI was significantly lower in exercised leg than non-exercised leg immediately after exercise (p<.05), although ABI decreased significantly in both legs after exercise (p<.05). 3. CAVI showed no significant difference between exercised leg and the non-exercised leg. 4. The muscle tension, stiffness increased significantly in exercised leg than non-exercised leg (p<.05) while elasticity decreased significantly in exercised leg than non-exercised leg immediately after exercise (p<.05). These results suggest that iso-kinetic-leg exercise may have effect on the changes of both arterial and muscle stiffness index of non-exercised leg as well as exercised leg.
