摘要


目的:探討在相同運動時間與平均強度下,比較固定強度與變動強度運動在能量消耗上的差異。方法:以12名大學健康男生為受試對象(年齡23.8±0.7歲、身高174.1±4.5公分、體重70.4±8.9公斤、最大攝氧量58.0±4.4 ml/kg/min、最大心跳率196.1±7.9 beats/min),本研究採重複量數設計,以平衡次序法先後進行平均運動強度為65% VO2max的固定強度(CON)、高變低強度 (H-L)與低變高強度運動(L-H),每次運動測驗至少間隔2天。最後資料再以單因子變異數分析進行統計分析。結果:CON、H-L與L-H在運動中的平均攝氧量、換氣量、心跳率、呼吸交換率與自覺努力程度皆無差異(p > .05)。在恢復期的能量消耗,H-L顯著高於CON與L-H (p < .05),但在總能量消耗上,三組卻無顯著差異(p > .05)。結論:(1)當運動時間相同且平均強度一致時,固定強度與變動強度在運動中的生理反應是相同。(2)運動結束的強度會直接影響恢復期的攝氧量。因此,變動強度運動可以影響恢復期的能量消耗,但對於總能量消耗的影響不大。

Purpose: The study aims at finding out the difference between constant and variable intensity (high to low, H-L ; low to high, L-H) exercises on energy consumption, provided the duration and the average intensity are the same. Methods: The subjects of the study are all healthy male college students (age: 23.8±0.7, height 174.1±4.5 cm, weight: 70.4±8.9 kg, VO2max: 58.0±4.4 ml/kg/min and HRmax:196.1±7.9 beats/min). Subjects performed 30 minutes of treadmill running at 65% VO2max with CON, L-H and H-L. Tests were all carried out two days away from the previous ones. The collected data was analyzed with one-way ANOVA. Results: The results show that in terms of VO2, VE, HR, RER and RPE, the differences between CON, H-L and L-H are insignificant (p > .05). In terms of energy consumption during recovery, L-H is significantly higher than CON and H-L (p < .05). However, in terms of total energy consumption, no significant difference has been found among the three groups (p > .05). Conclusions: (1) With the same duration and average intensity, no significant difference on energy consumption is found between constant intensity exercise and the variable counterparts (H-L & L-H). (2) The ending intensity of the exercise has a direct impact on VO2 during recovery. As a result, variable intensity exercise may influence the energy consumption during recovery, but in terms of the total energy consumption, the influence is only moderate.
