The Claim
Resistance exercise to failure on squat and bench press induces transient increases in arterial stiffness and sympathetic autonomic activity in resistance-trained women, and acute caffeine ingestion does not amplify these changes.
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 resistance-trained women, performing squat and bench press exercises to muscular failure causes temporary increases in arterial stiffness and sympathetic nervous system activity, and consuming caffeine before the workout does not make these increases larger.
See the scientific wording
Resistance exercise to failure on squat and bench press induces transient increases in arterial stiffness and sympathetic autonomic activity in resistance-trained women, but these changes are not amplified by acute caffeine ingestion.
When someone lifts heavy weights until they can't do another rep, the muscles squeeze hard and build up waste products, which triggers the nervous system to speed up the heart and tighten the arteries. Drinking caffeine before the workout doesn't change this process.
What the research says
1 studyThis study found that when women who regularly lift weights do heavy squats and bench presses until they can't do more, their arteries get stiffer and their heart stress signals go up — but drinking caffeine beforehand doesn’t make any of that worse.
