目的：本研究探討在三種不同橢圓機中，坡度、阻力及步頻對使用者生理指標的綜合影響。方法：以18名健康男學生（21.6±2.6歲、173.4±5.0公分、70.8±10.6公斤）為對象，受試者依據平衡次序原則，分別進行3種運動參數組合的不同橢圓機（型號：WT100、C7.5e、C8.5e）運動測驗（各含9種運動參數組合、測驗次序依據田口直交表順序進行、測驗時間為4分鐘、測驗間隔休息5分鐘），每種橢圓機測驗至少間隔24小時以上。記錄每種運動參數組合測驗第4分鐘時的RPE、平均V.O2、平均HR。資料處理以重複量數單因子變異數分析，顯著水準定為p＜.05。結果：相同運動參數組合下，使用WT100的RPE、V.O2、HR顯著大於使用C7.5e與C8.5e，使用C7.5e的RPE、V.O2、HR顯著大於使用C8.5e。使用3種橢圓機的阻力因子對RPE、V.O2及HR的影響最大，其次為步頻因子，最小為坡度因子。結論：無論以RPE、V.O2或HR做為運動強度指標，影響橢圓機運動強度的運動參數以阻力最大，其次為步頻，最小為坡度。

Purpose: This study was to investigate the combined effects of grade, resistance, and step frequency on users' physiological indicators among three different types of elliptical trainers. Methods: The participants were 18 healthy male students (21.6 ± 2.6 yrs, 173.4 ± 5.0 cm, and 70.8 ± 10.6 kg). Each participant had to take a combination test of 3 motion parameters in different elliptical trainer (Types: WT100, C7.5e, C8.5e) with a counterbalanced order. Each test includes 9 combinations and the order was based on Taguchi orthogonal array. Each combination lasted for 4 minutes and followed by a 5-minute break. There must be a 24-hour break between each different elliptical trainer test. The RPE, average VO2 and average HR were recorded at the end of the 4th minute in each combination. Data was processed by repeated measures of one-way ANOVA and a significant level was set at p ＜ .05. Results: In the same motion parameter, the RPE, VO2 and HR in WT100 were significantly higher than in C8.5e and C7.5e, and the all three indicators in C7.5e were significantly higher than in C8.5e. Resistance was the most effective motion parameter for RPE, VO2, and HR, the second was step frequency, and the last was gradient. Conclusions: Using RPE, VO2 and HR as physiological indicators to compare combined effects of 3 different types of elliptical trainers, the finding concludes that resistance may be the most effective factor, followed by step frequency and then gradient.
