中文摘要 | 緒論:阻力運動 (resistance exercise, RE) 可以提升運動後之過攝氧量 (excess post - exercise oxygen consumption, EPOC),而 EPOC的大小受到強度、組間休息 (rest interval, RI) 與訓練負荷量之影響。先前的研究分別證實高強度與短 RI可以顯著提升運動中之能量消耗與 EPOC。但強度與 RI對於阻力運動能量代謝反應之交互作用影響仍不清楚。研究目的:在探討阻力運動強度高低與組間休息期長短對於等訓練負荷量之阻力運動中與運動後能量代謝反應之影響。方法:本研究以 8名有規律阻力訓練的男性大專生為受試對象,所有受試者在進行 RE前皆進行最大肌力測驗 (1 repetition maximum, 1RM),隨後以重複量數與平衡次序設計分別進行高強度長 RI (5組、75% 1RM進行 10次反覆、組間休息時間為 2分鐘, HL)、高強度短 RI (5組、75% 1RM進行 10次反覆、組間休息時間為 1分鐘, HS)、低強度長 RI (5組、50% 1RM進行 15次反覆、組間休息時間為 2分鐘, LL) 與低強度短 RI (5組、50% 1RM進行 15次反覆、組間休息時間為 1分鐘, LS) 之阻力運動 [動作包含直立划船與半蹲舉;本研究之阻力運動是在史密斯訓練架 (smith machine) 上進行] 等 4次實驗處理。在安靜休息 (Rest)、運動中 (Exe1, Exe2) 與運動後 120分鐘 (R30, R60, R90, R120) 全程分析受試者之攝氧量 (oxygen consumption, VO2)、心跳率 (heart rate, HR)、換氣量 (ventilation volume, VE) 與呼吸交換率 (respiratory exchange ratio, RER)。本研究以相依樣本 2因子變異數分析 (ANOVA)分析參與者之能量消耗 (energy expenditure, EE)、運動後過攝氧量與 RER是否有顯著差異,顯著水準α訂為 .05。結果: HS在運動中與恢復期之 VO2, EE與 EPOC 皆顯著高於 HL, LS與 LL,此外, HL與 LS亦顯著高於 LL (p < .05),但 HL與 LS間卻無顯著差異存在 (p > .05)。各處理在運動後 60-120分鐘 (R60, R90, R120) 之 RER皆顯著低於安靜休息值 (Rest) (p < .05) 且各處理之 EPOC皆持續至 120分鐘。在生理指標方面, HR在 Eex2 (HS > LS, LL)、R30 (HL > LL)與 R60 (HS > LS) 達顯著差異。此外, VE在 Eex1、Eex2 (HS > HL, LS, LL; HL > LL; LS > LL) 與 R30 (HS > HL, LS, LL; LS > LL) 達顯著差異 (p < .05)。結論:本研究發現阻力運動強度越高,組間休息期越短,運動中的能量消耗與運動後過攝氧量越多。但進行低強度短組間休息期的阻力運動一樣能達到高強度長組間休息期在能量消耗上的效益。 |
英文摘要 | INTRODUCTION: Resistance exercise (RE) can significantly increase the magnitude of excess post-exercise oxygen consumption (EPOC), and which was affected by intensity, rest interval (RI) and training volume. Previous studies have demonstrated that high intensity and short RI could significantly increase the energy expenditure (EE) and EPOC following RE, but the interaction between intensity and RI on metabolic responses to RE is not clear yet. To investigate the effects of equal work resistance exercise with different intensity and rest interval (RI) on metabolic response during and after RE. METHODS: Eight university males who regularly performed RE participated in this study. After completing one repetition maximum (1RM) test, subjects performed 4 treatments in a counterbalanced order: high intensity and long rest (HL: 75% 1RM, 10rep; RI: 2min); high intensity and short rest (HS: 75% 1RM, 10rep; RI: 1min); low intensity and long rest. (LL: 50% 1RM, 15rep; RI: 2min) and low intensity and short rest (LS: 50% 1RM, 15rep; RI: 1min) RE (upright row and half squat which were performed on smith machine). The oxygen consumption (VO2), respiratory exchange ratio (RER), ventilation volume, (VE) and heart rate (HR) were measured during (Exe1 and Exe2) and after RE (R30, R60, R60 and R120). Statistical analysis of two-way analyze of variance with repeated measures was applied to analyze the differences of EE, EPOC and RER. Statistical significance was set at α = .05. RESULTS: VO2, EE, and EPOC during and after RE were significantly higher in HS than in HL, LS, and LL. In addition, HL and LS were significantly higher than LL (p < .05), but no difference was observed between HL and LS (p > .05). The RER at R60, R90 and R120 were significantly lower than Rest (p < .05). Moreover, the EPOC of HS, HL, LS and LL lasted for 120 min after RE. At other physiological index, there were significant differences in HR at Eex2 (HS > LS, LL), R30 (HL > LL) and R60 (HS > LS) among treatments. In addition, there were significant differences in V‧E at Eex1, Exe2 (HS > HL, LS, LL; HL > LL; LS > LL) and R30 (HS > HL, LS, LL; LS > LL) among treatments (p < .05). CONCLUSION: The results indicated that equal work RE with higher intensity or shorter RI produce higher EE and EPOC. However, the EE and EPOC levels of LS were no differences with HL. |
