登階測驗與身體組成預測最大攝氧量

V02max Predicted by Step Test and Body Composition

本研究主要目的在探討身體組成、登階測驗等相關生理參數與最大攝氧量之相關趨勢，並建立預測最大攝氧量迴歸模式。有效樣本共121名年齡為18至50歲的志願男性。所有受試者皆接受問卷調查、一般生理測驗及身體組成測驗，包括以皮脂夾法、BIA電阻法及BMI等評估身體組成，並各接受三分鐘登階測驗及漸增負荷強度的原地腳踏車最大攝氧量測驗，以了解相關生理參數情形，實測所得最大攝氧量為37.764±7.213ml/kg/min。經由逐步迴歸分析獲得四個不同的預測最大攝氧量迴歸模式，可解釋最大攝氧量66.1%以上的變異量，並且不具多元共線性以及實際可解釋變異量大幅縮減之現象，可提供預測一般男性健康成人之最大攝氧量。迴歸模式適用於相同背景之男性健康族群，應用者僅需蒐集一般性生理參數即可有效預測個體最大攝氧量水準，可避免科學儀器取得之不便性以及具危險性的高強度運動測驗流程，為深具實際應用價值之簡便有效的預測模式，可作為臨床評估心肺耐力與擬定運動訓練強度之參考。預測最大攝氧量迴歸模式：最大攝氧量= 76.402－.184（HR1）－.236（年齡）－.172（體重） R =.814 R=.663 SEE= ±3.5842 p<.01 最大攝氧量= 67.271－.175（HR1）－.189（年齡）－.327（電阻法Fat%） R =.813，R=.661 SEE= ±3.5958 p<.01 最大攝氧量= 98.936－.174（HR1）－.418（皮脂夾法Fat%）－.158（年齡）－.190（身高） R =.827 R=.684 SEE= ±3.4903 p<.01 最大攝氧量= 64.903－.160（HR1）－.165（年齡）－.155（腹部皮下脂肪厚）－.229（肱三頭肌皮下脂肪厚） R =.818 R=.670 SEE= ±3.5685 p<.01 單位說明：最大攝氧量（ml/kg/min）、年齡（歲）、體重（公斤）、腹部皮下脂肪厚（mm）、肱三頭肌皮下脂肪厚（mm）、電阻法Fat%（%）、皮脂夾法Fat%（%）、HR1登階後恢復期第一分鐘心跳率（次/分）。

The purpose of this study was to establish the predicted models of maximal oxygen intake (VO2max) with using body composition and step test. The effective samples were 121 voluntary healthy males. All subjects performed three minutes step test, maximal oxygen intake cycling test and body composition measurements, including height, weight, BMI, percentage body fat, and percentage body fat drawn from bioelectric insistence analysis (BIA) and subcutaneous skinfolds. The average VO2max was 37.764±7.213ml/kg/min. By stepwise regression analysis, the regression models of predicted VO2max was established as following. The contribution of this study was to apply to estimate the cardiorespiratory endurance and the reference of planning exercise prescription for healthy males. VO2max = 76.402－.184(HR1)－.236(age)－.172(weight) R =.814 R=.663 SEE= ±3.5842 p<.01 VO2max = 67.271－.175(HR1)－.189(age)－.327(BIA-Fat%) R =.813，R=.661 SEE= ±3.5958 p<.01 VO2max = 98.936－.174(HR1)－.418(skinfold Fat%)－.158(age)－.190(height) R =.827 R=.684 SEE= ±3.4903 p<.01 VO2max = 64.903－.160(HR1)－.165(age)－.155(abdominal skinfold)－.229(triceps skinfold) R =.818 R=.670 SEE= ±3.5685 p<.01 Units: VO2max(ml/kg/min), age(year), height(cm), weight(kg) , BIA-Fat%(%), abdominal skinfold(mm), triceps skinfold(mm), skinfold Fat%(%), HR1(bts/min).
