Intake of the catechin epigallocatechin gallate and caffeine has been shown to enhance exercise-induced fat oxidation. Matcha green tea powder contains catechins and caffeine and is consumed as a drink. We examined the effect of Matcha green tea drinks on metabolic, physiological, and perceived intensity responses during brisk walking. A total of 13 females (age: 27 ± 8 years, body mass: 65 ± 7 kg, height: 166 ± 6 cm) volunteered to participate in the study. Resting metabolic equivalent (1-MET) was measured using Douglas bags (1-MET: 3.4 ± 0.3 ml·kg-1·min-1). Participants completed an incremental walking protocol to establish the relationship between walking speed and oxygen uptake and individualize the walking speed at 5- or 6-MET. A randomized, crossover design was used with participants tested between Days 9 and 11 of the menstrual cycle (follicular phase). Participants consumed three drinks (each drink made with 1 g of Matcha premium grade; OMGTea Ltd., Brighton, UK) the day before and one drink 2 hr before the 30-min walk at 5- (n = 10) or 6-MET (walking speed: 5.8 ± 0.4 km/hr) with responses measured at 8-10, 18-20, and 28-30 min. Matcha had no effect on physiological and perceived intensity responses. Matcha resulted in lower respiratory exchange ratio (control: 0.84 ± 0.04; Matcha: 0.82 ± 0.04; p < .01) and enhanced fat oxidation during a 30-min brisk walk (control: 0.31 ± 0.10; Matcha: 0.35 ± 0.11 g/min; p < .01). Matcha green tea drinking can enhance exercise-induced fat oxidation in females. However, when regular brisk walking with 30-min bouts is being undertaken as part of a weight loss program, the metabolic effects of Matcha should not be overstated.

抹茶绿茶饮料可增强女性在轻快行走过程中的脂肪氧化。

已证明摄入儿茶素表没食子儿茶素没食子酸酯和咖啡因可增强运动引起的脂肪氧化。抹茶绿茶粉含有儿茶素和咖啡因，可作为饮料食用。我们检查了快走时抹茶绿茶饮料对代谢，生理和感知强度反应的影响。共有13位女性（年龄：27±8岁，体重：65±7 kg，身高：166±6 cm）自愿参加研究。使用道格拉斯袋（1-MET：3.4±0.3ml·kg-1·min-1）测量静止代谢当量（1-MET）。参与者完成了增量步行方案，以建立步行速度与氧气摄入量之间的关系，并在5或6-MET下个性化步行速度。随机的 在月经周期的第9天至第11天（卵泡期）之间对参加者进行了交叉设计。参与者前一天喝了3杯饮料（每种饮料都是用1克的Matcha高档咖啡制成的；英国布莱顿的OMGTea Ltd.），在5分钟（n = 10）或6-MET行走30分钟之前的2小时喝了一杯（步行速度：5.8±0.4 km / hr），并在8-10、18-20和28-30分钟时测得响应。抹茶对生理和感知强度反应没有影响。抹茶导致较低的呼吸交换率（对照：0.84±0.04;抹茶：0.82±0.04; p <.01），并在30分钟的轻快步行中增强了脂肪氧化（对照：0.31±0.10;抹茶：0.35±0.11 g / ； p <.01）。喝抹茶绿茶可以增强女性运动引起的脂肪氧化。然而，
