如何在運動的過程中充分的利用脂肪、代謝脂肪為能量來源,讓運動達到減脂,又能同時增進心肺適能,是近年來許多學者研究的重心,因此最大脂肪氧化之運動強度(Fat(下標 max)、最大脂肪氧化速率點(maximal fat oxidation rate point, LIPOX(下標 max)的觀念被提出。目的:本文旨在介紹Fat(下標 max)與LIPOX(下標 max)的定義、測量方法、判定方法,以及探討影響Fat(下標 max)或LIPOX(下標 max)的因子。方法:以文獻探討的方式,探討與Fat(下標 max)或LIPOX(下標 max)相關之文獻,作綜合評論。結果:Fat(下標 max)與LIPOX(下標 max)有集中在中、低強度上的現象。VO(下標 2max)、受試者特質(受訓練與否、肥胖、年齡、性別等特質)等因素會影響Fat(下標 max)與LIPOX(下標 max)。
It is an important subject how increase fat oxidation during exercise. Recently many studies emphasized on exercise intensity that promote cardiorespiratory fitness and fat oxidation simultaneously. A new concept of Fat(subscript max) (the exercise intensity at which maximal fat oxidation was observed) and LIPOX(subscript max) (maximal fat oxidation rate point) were presented in many studies. Purpose: This research aims were introduced the definitions, the measurement methods, the judging methods, the influencing factors of Fat(subscript max) and LIPOX(subscript max). Method: We reviewed many studies about Fat(subscript max) and LIPOX(subscript max). Results: Fat(subscript max) or LIPOX(subscript max) have a phenomenon concentrating on the low to moderate intensity. VO2(subscript max), subject's characteristics (trained or untrained, obesity, age, gender, etc.) will influence Fat(subscript max) or LIPOX(subscript max).
