不同強度心跳率控制1600 公尺跑走評量高中男生心肺適能之研究

Purpose: Cmpare the correlation of the different intensity 1600m run/walk elapsed run time by heart rate control (HRC) and the maximal oxygen uptake (VO2max). Method: The subjects were twenty-three healthy high school male students (age 17.09±0.90 years, height 171.83±5.31 cm, and weight 63.30±7.16 kg). Each subject had to take VO2max test followed by three different intensities 〔utmost efforts, 90% maximal heart rate (HRmax) (220-age), 80% HRmax〕 on 1600m run/walk tests by random order in the track and field within two weeks. During 90% and 80% HRmax tests, subjects had to wear polar heart rate monitor with HRCand based on 90% HRmax±5 bpm and 80% HRmax±5 bpm, self-adjusted running speed to go to complete 1600 m run/walk. In statistical analysis, we used the Pearson product-moment correlation to find the criterion-related validity of VO2max and different intensity 1600m run/walk elapsed run time. Result: The 1600m run/walk elapsed run time (utmost effort: 0.17±33.11 sec, 90%: 9.04±48.01 sec, 80%: 2.43±71.70 sec) significantly correlate to VO2max (48.89±5.92 ml/kg/min) in -0.59 (p＜.05), -0.51 (p＜.05), -0.36 (p＞.05). Conclusions: The 1600m run/walk tests with utmost efforts and 90% HRmax HRC could effectively evaluate cardio-respiratory fitness of high school male students. To consider the request on the security in school while proceeding to the test, we suggested that could use 90% HRmax HRC especially with those who were fat and who were not suit for intense exercise.
