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

Abstract

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 0.05). 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.
