最大脂肪氧化强度研究进展

Research Progress on Maximum Fat Oxidation Exercise Intensity

阐述了最大脂肪氧化运动强度(Fat_(max))进行减脂、促进健康的研究进展,为进行科学运动减脂提供了理论依据。Fat_(max)受最大脂肪氧化率(MFO)制约,而MFO随个体年龄增加而降低,训练有素的人MFO较高,且Fat_(max)较低,性别与肥胖程度对MFO的影响仍存有争议。药物(营养物)不同程度影响个体脂肪氧化;参与运动做功的肌肉量影响个体脂肪氧化。MIIT、HIIT、SIT有着与中等强度或Fat_(max)持续运动相比拟的减脂效果和健康促进作用;并阐述了不同强度运动的脂肪氧化机制。目前研究仍有4大问题亟待解决:(1)Fat_(max)的标准测试协议;(2)Fat_(max)是否是最佳减脂强度?(3)MIIT、HIIT、SIT运动的最佳减脂方案问题;(4)间歇运动减脂的机制:刺激的间歇性或脉动性对机体适应性反应起到怎样的作用?

This paper introduces the research progress of Fatmax in reducing fat and promoting health, which provides a theoretical basis for scientific exercise in reducing fat. Fatmax is restricted by MFO, and MFO decreases with the increase of individual age. The well-trained person has higher MFO and lower Fatmax. The influence of gender and obesity on MFO is still controversial. Drugs (nutrients) affect individual fat oxidation to varying degrees;muscle mass involved in exercise work affects individual fat oxidation. MIIT, HIIT and SIT have the same effect of reducing fat and promoting health as moderate intensity or Fatmax continuous exercise, and the mechanism of fat oxidation in different intensity exercise is expounded. At present, there are still four major problems to be solved urgently:1) Fatmax Standard Test protocol;2) Is Fatmax the best fat-reducing strength?3) MIIT, HIIT, SIT exercise the best program of reducing fat;4) Intermittent exercise mechanism of reducing fat: what effect does intermittent or pulsating stimulation have on the body’s adaptive response?
