The Effect of Three Weeks Green Tea Extract Consumption on Blood Pressure, Heart Rate Responses to a Single Bout Resistance Exercise in Hypertensive Women

High Blood Pressure & Cardiovascular Prevention Aims and scope Submit manuscript

Abstract

Introduction

Resistance exercise (RE) may lead to a post-exercise hypotension (PEH) response. Previous studies showed that green tea (GT) and its polyphenols, especially Epigallocatechin-3-gallate (EGCG) may have a favorable effect on blood pressure (BP).

Aim

We investigated the green tea extract (GTE) effects on BP, heart rate (HR), and rate pressure product (RPP) responses to a low-intensity RE in hypertensive women.

Methods

Middle-aged women (n = 24, 46.4 ± 6.3 years old; 66.6 ± 9.2 kg; 166.3 ± 4.2 cm) were randomly assigned into three groups of eight persons. GTE consumption group (T) and RE group (R), respectively, ingested GTE (~75 mg EGCG) and placebo (PL; maltodextrin) capsules two times a day for three weeks and then completed 2 circuits of six RE using 50% one repetition maximum (1RM). Patients of control group (C) just ingested PL and rested in a non-exercise control trial. BP, HR and RPP were measured prior and post-exercise at 0, 15, 30, 45, and 60 min.

Results

The repeated measures analysis of variance (ANOVA) revealed that there were no significant alterations for arterial BP, HR and RPP of C group. HR of T and R groups was increased immediately after RE. A significant fall of systolic BP (SBP) and diastolic BP (DBP) occurred in both T and R groups for 60 min post-exercise compared to resting values. Mean arterial BP (MAP) and RPP decreased significantly after RE in both exercise groups from 15 to 60 min. During 45 and 60 time points, T group had a lower RPP values than C group. The differences between T and R groups were only MAP at 0 and 15 time points.

Conclusions

Three weeks of GTE ingestion did not influenced SBP, DBP and HR but may be have a favorable effect on MAP and RPP responses to an acute RE during 1 h recovery of exercise.
