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

open access: yesExperimental 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.

Running on empty: Factors underpinning impaired cardiac output reserve in heart failure with preserved ejection fraction

open access: yesExperimental Physiology, EarlyView.
Abstract Heart failure with preserved ejection fraction (HFpEF) is frequently attributed etiologically to an underlying left ventricular (LV) diastolic dysfunction, although its pathophysiology is far more complex and can exhibit significant variations among patients. This review endeavours to systematically unravel the pathophysiological heterogeneity

Exercise echocardiography for improved assessment of diastolic filling dynamics

open access: yesExperimental Physiology, EarlyView.
Abstract During exercise stress, heart rate (HR) increases to support cardiac output, which also reduces ventricular filling time. Although echocardiography is widely used to assess cardiac function, studies display conflicting data on the dynamic changes in the healthy trained and untrained heart during rest and acute exercise stress. To address these

Effects of noradrenaline and phenylephrine on cerebral oxygen saturation during cardiopulmonary bypass in cardiac surgery

open access: yesExperimental Physiology, EarlyView.
Abstract Cardiopulmonary bypass (CPB) in cardiac surgery is associated with a high risk of postoperative neurological complications. Perioperative use of vasopressors is common to counteract arterial hypotension in this setting. However, use of α‐agonist vasopressors has been associated with cerebral desaturations.
