Combined impact of green coffee bean extract consumption and concurrent training on arterial blood pressure in overweight and obese women

Context: Green coffee ingestion improves blood pressure in healthy humans, but the interactive effect of green coffee and exercise is unknown.Aims: The purpose was to determine the combined effect of green coffee bean extract (GCE) consumption and concurrent training (CT) on arterial blood pressure in overweight and obese women.Setting and Design: This study was an experimental pilot study, which was conducted in 2017.Materials and Methods: Among overweight and obese women of the Rasht city, 30 participants were allocated to three groups via simple randomization to receive treatment with GCE (125 mg, twice/day, before lunch and dinner), CT (four sessions aerobic-resistance training/week), or both. Systole blood pressure (SBP), diastole blood pressure (DBP), heart rate, and mean arterial pressure (MAP) were measured before and 48 h after interventions.Statistical Analysis Used: Mean and standard deviation, analysis of covariance, and paired sample t-test were used.Results: Heart rate decreased in all intervention groups (P < 0.01). GCE-CT treatment showed significantly decreased SBP (P = 0.04). CT group indicated significant reduction for DBP and MAP (P = 0.03 and P = 0.02, respectively). However, there were no significant difference between study groups for SBP, DBP, and MAP (P > 0.05).Conclusion: It seems that GCE, CT, or combination of both had a little effect for improving arterial blood pressure, and therefore, simultaneous effect of CT-GCE was not more effective than CT or GCE for improving the blood pressure in women with normal blood pressure.
