The purpose of the study is to invastigate the effects of myofascaial release on heart rate variability and stiffness of rectus femoris after ergometer exercise. In a cross-over design, 9 young(22.75±1.89years) healthy males performed two incremental 70% HRR cycling bouts, and the neither 10 min of myofascial release or passive rest. The parameters of heart rate variability were obtained from both time-and frequency domain analysis of 5min ECG recording at rest, immediately after exercise and recovery 10min. Standard deviation of the node to node interval(SDNN) and root mean square of successive differences(RMSSD) and the low and high frequency components were calculated as normalized units. 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 muscle at rest, immediately after exercise and recovery 10min. From the Myoton measurement, Five indexes (Frequency, Logarithmic Decrement, Dynamic Stiffness, Creep and Mechanical Stress Relaxation) were obtained. The results are as follows: 1. Analysis of HRV revealed a significant increase in sympathetic activity and a significant decrease in parasympathetic activity following ergometer exercise with no significant difference between both groups. 2. The muscle tension and stiffness increased significantly while the elasticity decreased immediately after exercise while no significant effect of myofascial release on mechanical properties indexes was found during recovery period. The results represent that these application of MR technique might influence personal feeling and none-specific recovery from muscle fatigue without any statistically significant change of muscle mechanical properties and heart rate variability.
