The Effects of Green Tea Consumption and Resistance Training on Body Composition and Resting Metabolic Rate in Overweight or Obese Women

Abstract

Green tea has been shown to have thermogenic and antiobesity properties. Therefore, it is important to investigate its effect on weight loss in humans, especially in women. We investigated the effects of green tea consumption combined with resistance training on the body composition and the resting metabolic rate (RMR) in women who were overweight or obese (grade I). After 4 weeks on an adaptive diet, 36 women were divided into four groups (group 1 green tea; group 2 placebo; group 3 green tea plus resistance training; group 4 placebo plus resistance training). The study was double-blinded and placebo-controlled. The RMR and body composition were ascertained for each volunteer, blood tests were performed, and subjects in groups 3 and 4 were tested for their one repetition maximum. Each subject followed the protocol and continued the diet for eight additional weeks, and periodic evaluations were administered. The mean RMR of group 1 decreased significantly and was accompanied by weight loss, maintenance of lean body mass, and decreases in both waist circumference and body mass index. Group 2 showed no variations in anthropometric or blood variables and significantly decreased their mean RMR. Group 3 showed significant increases in RMR, lean body mass, and muscle strength, and significant decreases in body fat, triglycerides, and waist circumference as compared to group 4. Green tea combined with resistance training its potential is increased with decreasing body fat, waist circumference, and triacylglyceride levels and by increasing lean body mass and muscle strength.

A Systematic Review and Meta-Analysis of the Effects of Flavanol-Containing Tea, Cocoa and Apple Products on Body Composition and Blood Lipids: Exploring the Factors Responsible for Variability in Their Efficacy

“…After detailed analysis of the full text, 71 articles were excluded, due to lack of relevant outcomes, aspects of study design or publication language. The final number of articles selected for meta-analysis was selected from a total of 117 articles published between 1997 and July 2015 (included) [21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,…”

Effects of Hemp (Cannabis sativa L.) Seed Oil Press‐Cake and Decaffeinated Green Tea Leaves (Camellia sinensis) on Functional Characteristics of Gluten‐Free Crackers

“…It contains polyphenols, which include flavanols (catechins), flavandiols, flavonoids, and phenolic acids (Chow and Hakim ). Tea catechins have been shown to have health benefits including cancer prevention of many types (Cabrera and others ), decreasing LDL cholesterol level (Kim and others ), and antiobesity effects (Cardoso and others ). Green tea extract was used to stabilize the lipid oxidation rate of omega‐3 oils incorporated into table spreads (O'Dwyer and others ).…”

The Effect of Continues Aerobic Training with Green Tea Supplementation on Lipid Profiles of Inactive Obese Females

“…Consumption of foods contain flavonoides may lead to decrease in mortality due to disease (13). As food that is Profuse of flavonoide may referred to tea and cola (14). These Substances mainly contain Catechins such as epigallocatechin-3-gallate (EGCG), epigallocatechin (EGC) and epicatechin (EC).…”

“…Although, there is evidences that indicated that EGCG has metabolic role and may be effective in body fat reduction (16). Also, EGCG causes to reduction in food intake and decreases levels of blood triglycerides and cholesterol and increases HDL (14). Some studies showed that catechins of green tea lead to clearing risk factors related to atherosclerosis and hypertension through reduction of LDL oxidation, cholesterol absorption and decreases systolic and diastolic pressure (17,18).…”
