中文摘要 | 目的:觀測最大脂肪代謝(maximal fat oxidation, FATmax)運動強度的呈現情形,以及FATmax運動強度和最大攝氧量(maximal oxygen uptake, VO(下标 2max))之相關,以便建立更完整的FATmax理論依據。方法:受試對象為12位經常運動的大學男性(年齡21.25±1.83歲、身高175.75±6.38公分、體重為71.42±9.33公斤、BMI為23.08±2.34)。本實驗採用受試者內設計,參考Achten, Venables, and Jeukendrup(2003)之跑步機FATmax運動強度測驗流程,以速度5.5km/h與6.5km/h、坡度1%各進行三分鐘的熱身後,以速度7.5km/h、坡度1%、每三分鐘增加坡度2%的方式進行FATmax跑步測驗,直到RER達到0.9後,進行速度10km/h坡度10%、每三分鐘增加速度2km/h之VO(下标 2max)測驗至衰竭。受試者同時在一次跑步測驗流程中檢測出FATmax運動強度與VO(下标 2max),並將所得之資料以皮爾遜積差相關方法比較FATmax運動強度與VO(下标 2max)之相關情形。結果:FATmax運動強度(35.49±8.13ml/kg/min)為VO(下标 2max)(57.59±6.69ml/kg/min)的68.43±10.46%。在FATmax運動強度與VO(下标 2max)之間呈現顯著的相關(r=.77),顯示出FATmax運動強度會受到個體最大有氧能力的影響;從FATmax運動強度的分布,可發現其仍呈現一個廣泛的區域(wide range zone)的現象。結論:漸增負荷運動的檢測流程為檢測FATmax運動強度的有效方式。為了增加運動時的脂肪代謝量,具備較佳有氧運動能力的運動參與者應選擇較高的運動強度。 |
英文摘要 | Purpose: The purpose of this study was to investigate the distribution of maximal fat oxidation (FATmax), and the correlation between FATmax and maximal oxygen uptake VO(subscript 2max) in order to establish a more complete theory model of FATmax. Method: Twelve moderately trained male college students (age 21.25±1.83 yr, height 175.5±6.38 cm, weight 71.42±9.33 kg, BMI 23.08±2.34) This is a within-subjects design experiment based on Achten, Venables, and Jeukendrup (2003) FATmax treadmill protocol. It started with a three-minute warming up at 5.5 km/h and 6.5 km/h, at a gradient of 1% respectively, follows the running exercise test started at 7.5 km/h, at 1% and the gradient of the treadmill was increased with 2% until an RER of 0.9 was reached. The subjects then started running at a speed of 10 km/h at 10% and speed was further increased by 2 km/h every 3 minutes until exhaustion. Gas exchange measurements were performed throughout exercise. Fat oxidation rates were calculated using stoichiometic equations. The results of FATmax and VO(subscript 2max) are derived from the above protocol at the same time and compared the correlation with each other with Pearson's product-moment Correlation method. Results: FATmax was located between 35.49±7.78 ml/kg/min; 68.43±10.46% VO(subscript 2max) (51.59±6.69 ml/kg/min). The FATmax and VO(subscript 2max) have a significant correlation with each other (r=0.77). It represents that FATmax will be influenced by VO(subscript 2max) significantly. And FATmax presents a wide range zone phenomenon, which corresponds to previous literature. Conclusion: Graded exercise is an efficient protocol to determine the FATmax. In order to increase fat oxidation rate, participants with better aerobic ability should choose higher exercise intensity. |
