If you’re taking beta blockers, it must be disclosed on your VO₂ max intake form. 🫀
These medications lower heart rate and blunt your HR response to exercise — meaning your test results can look very different if we don’t account for it. Research shows that clinical doses of beta blockers can reduce VO₂ max by 5–15% in both healthy and trained individuals.
That’s why transparency = accurate data — so we can properly interpret your aerobic capacity, training zones, and cardiovascular efficiency. ✔️
