The study was designed to evaluate the effect of self-myofascial release(SMR) technique on elasticity and stiffness of rectus femoris muscle which experienced the exhaustive fatigue induced by isokinetic endurance exercise. Total 25 college students(male: 14, female: 11) conducted two isokinetic endurance exercise(Biodex System 4, USA) with a week interval. In this cross-over study, each subject were asked to perform 6 sets of muscular endurance exercise(60°/sec, 10 times of maximal knee flexion and extension/each set) with 10seconds of resting interval. Each subject was asked to conduct SMR treatment on rectus femoris(experimental group) or take a complete resting(control group) for 5 minutes after 6 sets of isokinetic endurance exercise at each separated day with a week interval. In order to measure eth mechanical properties like muscle stiffness and elasticity, MyotonPro(Myoton AS, Tallinn, Estonia) was applied to muscle belly of rectus femoris muscle at pre-exercise, right after exercise, 5min. and 20min. after exercise. From the Myoton measurement, Five indexes(Frequency, Logarithmic Decrement, Dynamic Stiffness, Creep, Mechanical Stress Relaxation) were obtained. Electromyograph(EMG) on rectus fermoris m. was also measured during first set and 6th set of isokinetic exercise in order to obtained the muscle activity index and compare it with Myoton measurement indexes. The results were as follows:
1. The muscle tension and stiffness were significantly increased while the elasticity was decreased immediately and at 5 minutes after exercise. All mechanical properties of fatigued muscle were recovered to pre-exercise level at 20 minutes after exercise. 2. No significant effect of SMR on mechanical properties indexes of fatigued muscle was found at every time point after endurance exercise. 3. The changes of mechanical properties(tension, stiffness and elasticity) between pre-and post-exercise which were measured by Myoton-measurement had significant corelation with the changed muscle activities estimated by EMG.
