Abstract

Aim: Metabolic syndrome (MetS) is one of the leading causes of disability and mortality worldwide, characterized by a cluster of multiple cardiometabolic risk factors. Physical activity and green tea consumption appear to have similar effects on various diseases, particularly on the components of MetS.

Method: In this study, 32 sedentary women (age: 23 ± 3.2 years, BMI: 28.6 ± 1.8 kg/m²) were randomly assigned to one of four groups: control [CO], exercise [EX], green tea [GT], and exercise + green tea [EX+GT]. Participants in the EX and EX+GT groups engaged in a supervised exercise program for six weeks, three sessions per week. The aerobic training program consisted of a series of aerobic exercises and jogging at 65–80% of maximum heart rate (MHR), and resistance training at 45–60% of one-repetition maximum (1RM).

Results: The EX+GT group showed a significant reduction in total cholesterol (TC), triglycerides (TG), glucose, and hs-CRP, along with a significant increase in HDL and albumin levels compared to the control group (p<0.05). In the GT group, significant reductions in TC and hs-CRP levels and an increase in HDL were observed compared to the control group (p<0.05).

Conclusion: This study on healthy women revealed no significant differences in most variables among the groups, except for the concomitant use of green tea with exercise training, highlighting the additive beneficial effects of green tea consumption.
