The Claim
Caffeine at a dosage of 0.003 g/kg body weight significantly increases diastolic blood pressure by approximately 4.7 mmHg compared to placebo or sodium bicarbonate in young, resistance-trained adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In young adults who regularly lift weights, consuming caffeine at a dose of 0.003 grams per kilogram of body weight raises diastolic blood pressure by about 4.7 mmHg compared to taking a placebo or sodium bicarbonate.
See the scientific wording
Caffeine at 0.003 g/kg body weight significantly increases diastolic blood pressure by approximately 4.7 mmHg compared to placebo or sodium bicarbonate in young, resistance-trained adults, indicating a measurable cardiovascular response despite lack of ergogenic effect.
Caffeine blocks natural calming signals in the body, causing nerves to release more adrenaline-like chemicals that tighten blood vessels, which raises the lower number in blood pressure readings.
What the research says
1 studyEven though a tiny amount of caffeine didn’t help people lift more weights, it did slightly raise their bottom blood pressure number by about 5 points — just like the claim said.
