目的：比較不同強度心跳率控制(heart rate control, HRC)1600公尺跑走成績，與最大攝氧量(maximal oxygen uptake, VO2O max)的相關性，藉以確認不同強度HRC跑走測驗對於評量心肺適能的效度。方法：受試對象為健康的高中男學生23位（年齡17.09±0.90歲、身高171.83±5.31公分、體重63.30±7.16公斤）。每位受試者依據平衡次序原則，先進行實驗室內跑步機漸增強度的VO2 max測驗後，再於兩週內進行三種不同強度〔最大努力、90%最大心跳率（maximal heart rate, HRmax，以220-年齡來代表）、80%HRmax〕的田徑場1600公尺跑走測驗，每項測驗之間至少需間隔24小時以上。當進行90%與80%HRmax測驗時，需讓受試者配戴Polar心跳監測器進行心跳率控制，即以90%HRmax±5bpm與80%HRmax±5bpm，自行調整跑步速度至完成1600公尺。統計分析以皮爾森積差相關統計法，針對不同強度1600公尺跑走成績與VO2 max進行效標關聯效度考驗。結果：最大努力1600公尺跑走(410.17±33.11sec)、90%HRmax的HRC1600公尺跑走(459.04±48.01sec)、80%HRmax的HRC1600公尺跑走(552.43±71.70sec)與VO2 max (48.89±5.92ml/kg/min)的相關分別為-0.59(p<.05)、-0.51(p<.05)、-0.36(p>.05)。結論：最大努力與90%HRmax的HRC1600公尺跑走測驗皆有評估高中男生心肺適能的效果。學校在實施心肺適能的1600公尺檢測時，若考量測驗的安全性，尤其是對於肥胖或不適合激烈運動者，建議可用非最大努力的90% HRmax HRC方式進行施測。

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.
