The effects of caffeine ingestion on blood pressure levels in athletic and non-athletic women

Daniyah K. Al-Shebel, Noorah S Al-Sowayan

Abstract

Caffeine is one of the most widely consumed pharmacological substances globally, and is known for its potential ergogenic effects. This study examined the impact of caffeine on the blood pressure in athletic and non-athletic women. Caffeine, a CNS stimulant, enhances athletic performance by boosting stamina, alertness, and cognitive speed. The aim of this study was to assess the impact of caffeine on heart rate and blood pressure in both athletic and non-athletic women, and to inform both groups about its effects. The study was conducted in the Kingdom of Saudi Arabia and involved 30 volunteers aged 18–30 years. Participants were equally divided into three groups: athletes who consumed caffeine, non-athletes who consumed caffeine, and a control group (given a placebo). After caffeine ingestion, there were no significant differences in diastolic blood pressure (DBP), systolic blood pressure (SBP), or heart rate between athletes and non-athletes. These findings suggest that caffeine consumption does not significantly affect blood pressure in either athletic or non-athletic women. However, if it raises blood pressure in both groups, it could pose risks, prompting athletes to consider alternative hydration options such as Gatorade. (Afr J Reprod Health 2024; 28 [5]: 84-89)
