Matcha Green Tea Drinks Enhance Fat Oxidation During Brisk Walking in Females

Abstract

19Intake of the catechin epigallocatechin gallate and caffeine has been shown to enhance 20 exercise-induced fat oxidation. Matcha green tea powder contains catechins and caffeine and 21 is consumed as a drink. We examined the effect of Matcha green tea drinks on metabolic,

Three Weeks Daily Intake of Matcha Green Tea Powder Affects Substrate Oxidation during Moderate-Intensity Exercise in Females

“…A study by Willems et al (2018) observed an increase in exercise-induced fat oxidation by 18% following short term intake consisting of 3 cups of Matcha on the day before and one cup of Matcha on the day of testing. In the present study, the exercise-induced fat oxidation after 3-weeks intake of Matcha green tea capsules was almost double, by 35%.…”

“…Observations from in-vivo studies in humans on the effects of Matcha are limited (e.g. Dietz et al 2017, Willems et al 2018. Dietz et al (2017) reported acute effects of Matcha green tea powder (4 grams) on specific attentional tasks.…”

“…Dietz et al (2017) reported acute effects of Matcha green tea powder (4 grams) on specific attentional tasks. As far as we know, Willems et al (2018) is the only study that examined the effects of Matcha consumption and exercise-induced metabolic responses. It was observed that the drinking of four cups of Matcha (3 cups the day before and 1 cup on the day of testing, each cup made up with 1 gram of Matcha) enhanced fat oxidation by 18% during brisk walking in females and lowered the respiratory exchange ratio (Willems et al 2018).…”

The respiratory exchange ratio provides the relative contribution of carbohydrate and fat oxidation to total energy expenditure, and a lower value by an intervention is considered to be beneficial as there is more reliance of fat as a substrate.…”

“…decaffeinated green tea extract, Roberts et al 2015). While the study by Willems et al (2018) demonstrated short term benefits, the mechanisms for enhanced fat oxidation by green tea extract may differ between short-and long-term intake (Hodgson et al 2013). In addition, for individuals to respond to supplement-induced fat oxidation during exercise may affect their metabolic flexibility (see Hogdson et al 2013).…”
