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).


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.


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.


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.


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.
