| Summary: | 碩士 === 國立中正大學 === 運動與休閒教育所 === 96 === Purpose: Conferred the difference of oxygen uptake (VO2) and exercise velocity between high-intensity interval exercise (HIIE) with heart rate control (HRC) and HIIE with 90% maximal oxygen uptake (VO2max) to set the target heart rate in HIIE of HRC intensity. Method: There were seven males and five females students team of track and field in senior high school as subjects [age 17.33 (0.89) yrs, height 168.58 (7.33) cm, weight 61.05 (7.13) kg]. Every subject took the exercise test of gradual increasing load to measure VO2max and 24 hours later took HIIE test of 90% VO2max six stages (4 minutes per stage and 2 minutes break in each stage) and recorded every 10 seconds during exercise and break. Then they took HIIE of HRC intensity test twice with six stages (4 minutes per stage and 2 minutes break in each stage) and using 85%, 85%, 90%, 90%, 90% and 90% maximal heart rate (HRmax). Two-way split-plot ANOVA was employed to determine the difference of VO2 and velocity in the last 30 seconds of each stage in HIIE of 90% VO2max test and HIIE of HRC intensity test. Intraclass correlation coefficient was employed to determine the retest reliability in two HIIE of HRC intensity test. Result: There were significant differences (p<.05) in VO2 (p=.002) and velocity (p=.001) during every stage by HIIE of 90% VO2max test and HIIE of HRC intensity test. The retest reliability were significant correlation (p<.05) of two HIIE of HRC intensity test in VO2 (r=0.94~0.97) and velocity (r=0.92~0.95). Conclusion: Designing the HIIE of HRC intensity test protocol according to heart rate responses in HIIE of 90% VO2max test is a well method in HIIE training with high repetitious exercise physiology responses.
