Borg 6~20量表和OMNI量表之自覺強度與各生理反應之相關比較

Abstract

目的：本研究目的在比較Borg 6~20量表和OMNI量表於腳踏車衰竭性運動中，所得之RPE值與各生理反應的相關。方法：本研究以三十位體育系之健康男性（年齡：20.03 ± 2.22歲；身高：175.37 ± 4.57公分；體重：70.57 ± 7.33公斤；身體質量指數：22.91 ± 1.85公斤/公尺2）為受試對象，每位受試者以平衡次序方式，分別使用Borg 6~20量表和OMNI量表，在原地腳踏車測功儀上各進行一次衰竭性運動測驗。測驗過程中記錄受試者各階段的心跳率、換氣量、攝氧量、呼吸交換率、RPE值等人體生理反應值。實驗所得之資料以皮爾遜積差相關進行分析，以得到各生理反應和兩種量表之相關係數；再以相依樣本t考驗比較相關係數間之差異顯著情形。結果：兩種量表所得之RPE值與心跳率、換氣量、攝氧量、呼吸交換率反應等生理變項有顯著相關 ( p< .05)；Borg 6~20和OMNI兩種量表所得RPE值與各生理反應之相關係數間無顯著差異。結論：在原地腳踏車上進行漸增式運動測驗時，使用Borg 6~20量表或OMNI量表，皆能準確反應成人在運動過程中各項生理指標。Purpose: The purpose of this study was to investigate the RPE value and the relationship of physiological responses in comparing Borg 6~20 scale and OMNI scale during the exhaustive exercise on bicycle ergometer. Methods: 30 healthy males students (age: 20.03 ± 2.22 years; height: 175.37 ± 4.57 cm; weight: 70.57 ± 7.33 kg; BMI: 22.91 ± 1.85 kg/m2) of the Department of Physical Education were tested in this study. Each testing subject used Borg 6~20 scale and OMNI scale respectively by counter-balance design, and did the testing of the exhaustive exercise on bicycle ergometer. Heart rate, ventilation, oxygen consumption, respiratory exchange rate, and RPE value of every subject during each stage were measured when exercising. Pearson’s correlation was applied to get the correlation between RPE value of two kinds of scales and physiological responses. Dependent t-test was applied to compare the correlation between two kinds of scales. Results: The RPE value of the two scales were significantly correlated with heart rate, ventilation, oxygen consumption and respiratory exchange rate ( p<.05). And the correlation coefficients were not significantly different between the two kinds of scales. Conclusion: The Borg 6~20 scale and OMNI scale are all good for identifying exercise intensity for adults during incremental exercise testing.
