Please explain how taking a beta-blocker can have serious implications for someone beginning a new workout regimen?
Beta-blockers action is to block the effects of the hormone epinephrine on the myocardium of the heart. This stunts the rate at which the heart can pump per minute, which reduces cardiac output. A decrease in cardiac output reduces blood flow, which reduces tissue perfusion, resulting in poor tissue performance at the cellular level, where oxygen is converted into ATP, used to contract muscles.
