They do not significantly impair exercise capacity. Gordon NF(1), Duncan JJ. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. 5 Beta-blockers are a class of medication used to block the effects of stress hormones such as adrenaline on the heart.

Namely, they act on the beta receptors found in smooth muscle tissue. Exercise performance and beta-blockade.
Beta Blockers and Exercise In case of heart patients, beta blockers put a cap on the maximum heart rate and therefore, it does put restrictions on their exercise and stamina. As exercise has been shown to have psychological benefits, a team of researchers at University of Birmingham Medical School decided to investigate whether physical activity would help to offset B-blockers’ adverse effects on mood (‘Acute effects of B-blockade and exercise on mood and anxiety’, A.
