초록

Thirty healthy adults aged 20 to 29 with no history of musculoskeletal or neurogenic disorder volunteered for this study. The contract-relax with agonist contration(CRAC) was applied to the right hamstring muscles with the subject in the supine position. Each hamstring group was stretched on three sucessive days with several repetitions of the technique lasting 1min, 3min, and 5min. respectively. Hamstring extensibility at the knee(ROM) was measured before and after stretching using on electronic digital inclinometer(EDI). The results, namely the increase in ROM, were analysed using one-way repeated ANOVA at p<0.05. The differences were not significant. Possible factors influencing the results are excessive sensitibility of the measuring instrument, the psychological and physical status of the subjects, and the level of muscle fatigue. The mean increases in ROM were 3.0 at 1min., 2.6 at 3min, and 2.1 at 5min. Inclusion of a control group would have further defined the effects of the stretching technique.
