| Summary: | 碩士 === 國立臺南大學 === 體育學系碩士班 === 99 === Purpose：The Purpose of this study is to explore the effect of different heart rate recovery after warm-up on VO2max performance. Methods：First find nine track and field team members who major in the department of physical education as research object. They are 22 (1.5) years old, 174.0(4.6)cm high, and 64.7(6.8)kg on average. Then ask them to warm up for 5 to 10 minutes until the heartbeat rate reach 160 beats/min. Next do the VO2max test while their heart rates descend to 140 beats/min, 100 beats/min, and 80 beats/min. In addition to the VO2max test, measuring the accumulation of blood lactate as well as the heart rate and RPE of the 1st, 3rd, 5th,7th minute while doing the experiment. Finally analyze the statistics through three dimensions: (1) Comparison of the accumulation of blood lactate by one-way ANOVA. (2) The sport performance of three kinds of heart rate recovery & RPE by one-way ANOVA, repeated measures. (3) The variation of heart rate under three kinds of heart rate recovery by Two-way ANOVA. Results: According to the statistics, the heart rate, the heart rate in exercise, blood lactate, and RPE have no obvious differences (P>.05) under three heart rate recovery(from 160beats/min to 140 beats/min, 100 beats/min, and 80 beats/min). However; on Maximal Aerobic Power Performance, the heart rate recovery from 160 beats/min to 100 beats/min is better than the others (P<.05). Conclusion: As a result, the experiment shows that the heart rate recovery from 160 beats/min to 100 beats/min facilitates the the sport performance of VO2max.
