| Summary: | 碩士 === 國立體育大學 === 運動與健康科學學院 === 106 === The combination of Blood flow restriction (BFR) and low-intensity training breaks the traditional belief that resistance training can induce muscle growth when exercise intensity must greater than 65% of the one maximum repetition (RM). And can quickly mobilize muscle recruitment, to enhance athlete sports performance. The purpose of the study is to combine the BFR in the warm-up process for the short-term improvement of the athlete's performance after the warm-up. Research Methods: Eight healthy athletes (age 19.125±3.090 years, height 164.625±9.395 cm, weight 64.587±10.510 kg) were used as objects, and repeated experimental designs were conducted to receive BFR pressure strengths of 0%, 20%, and 40%, respectively. 60% femoral arterial blood pressure intensity, resting two days between each experiment. Before each experiment, the resting heart rate and the femoral artery blood pressure were measured, and the heart rate change per minute was measured during the warm-up period, and the one-minute jumping ability after the warm-up (height, maximum strength, and interest rate) was measured. The comparison between the heart rate changes and the exercise performance at different pressure was analyzed by the method of One-Way ANOVA. RESULTS: The differences in heart rate changes per minute and pressure-time were noted during the warm-up period was noted significantly. However, the performance of the exercise did not reach a significant level. Conclusion: 20%, 40%, 60% pressure with time prolonged, compared with 0% pressure blood flow restriction, heart rate reached significantly, As time prolonged, compared with 0% pressure blood flow restriction, the heart rate of 20%, 40%, and 60% pressure blood flow restriction reached significantly.
With greater the pressure, the heart rate changes was prominent, however the level of jumping ability cannot be improved in a short period of time
