Cardiac output‐mediated regulation of cerebral blood flow during exercise: Clinical perspectives on the indirect impact of muscle metaboreflex

Experimental Physiology, EarlyView.
Abstract The muscle metaboreflex stimulates the elevation of arterial blood pressure, aiming to rectify the oxygen deficit by enhancing oxygen delivery to support muscle activity. Moreover, activating the muscle metaboreflex significantly increases cardiac output (CO) by increasing factors such as heart rate, ventricular contractility, preload, stroke ...

Cardiac output limits maximal oxygen consumption, but what limits maximal cardiac output?

Experimental Physiology, EarlyView.
Abstract Maximal oxygen uptake/consumption is an important variable determining exercise performance. It is generally considered to be limited largely, but not exclusively, by maximal cardiac output (CO), which limits the ability of heart to pump oxygen‐rich arterial blood to working muscles. Cardiac output is a product of heart rate and stroke volume,

Intensified training augments cardiac function, but not blood volume, in male youth elite ice hockey team players

Experimental Physiology, EarlyView.
Abstract While it is well‐established that a period of interval training performed at near maximal effort, such as speed endurance training (SET), enhances intense exercise performance in well‐trained individuals, less is known about its effect on cardiac morphology and function as well as blood volume.

Mechanisms mediating muscle metaboreflex control of cardiac output during exercise: Impaired regulation in heart failure

Experimental Physiology, EarlyView.
Abstract The ability to increase cardiac output during dynamic exercise is paramount for the ability to maintain workload performance. Reflex control of the cardiovascular system during exercise is complex and multifaceted involving multiple feedforward and feedback systems.
