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

Experimental Physiology
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 ...

Validity of aerobic capacity indicators derived from the progressive specific taekwondo test for prescribing sport-specific interval training

Frontiers in Physiology
BackgroundThe Progressive Specific Taekwondo Test (PSTT) is used to determine indicators of aerobic capacity (heart rate deflection point [HRDP] and kick frequency at the HRDP [KFDP]) useful for prescribing sport-specific training.

Mitochondrial transplantation combined with coenzyme Q10 induces cardioprotection and mitochondrial improvement in aged male rats with reperfusion injury

Experimental Physiology
Ischaemic heart diseases (IHD) are among the major causes of mortality in the elderly population. Although timely reperfusion is a common treatment for IHD, it causes additional damage to the ischaemic myocardium known as ischaemia–reperfusion (IR ...

Adaptation of thoracic and lumbar curvature and spinal muscle activity under changing gravity

Frontiers in Physiology
IntroductionThe effect of micro-gravity on the lumbar and in particular thoracic regions is poorly understood. The aim of this study was to evaluate spinal curvature across the lumbar and thoracic region, and extensor muscle activity during acute micro ...
