Corticospinal, reticulospinal and motoneuronal contributions to fatigability during a sustained contraction of the elbow flexors

Experimental Physiology, EarlyView.
Abstract Synaptic input to the motoneuron pool is altered during fatiguing muscle contractions. In humans, the corticospinal tract is often studied, with equivocal findings regarding its role in the reduction of force. To date, the involvement of the reticulospinal tract during states of fatigue has not been explored.

Effects of a high‐sugar mixed meal on cerebrovascular haemodynamics in young, healthy versus middle‐aged adults with cardiometabolic risk factors

Experimental Physiology, EarlyView.
Abstract Consumption of a high‐sugar mixed meal (HSMM) increases both glucose and insulin and elicits mixed vascular effects, with reduced microvascular blood flow but increased conduit artery diameter and blood flow. In this study, we sought to examine: (1) whether an HSMM elicits vascular segment‐specific effects within cerebrovasculature; and (2 ...

CARE‐ing for concussions: Development of the Calgary Adapted aRm Ergometer (CARE) exertion test: A physiological alternative to the Calgary Concussion Cycle Test

Experimental Physiology, EarlyView.
Abstract Aerobic exercise testing helps facilitate recovery post‐concussion. Current protocols (Calgary Concussion Cycling Test: CCCT) are inaccessible for athletes with lower‐body impairments (i.e. Para athletes). This study compared physiological parameters for a novel arm crank test, the Calgary Adapted aRm Ergometer (CARE) test, with the CCCT ...

Effect of hypoxia on muscle activation at equivalent absolute and relative intensity during incremental and constant load exercise to task failure

Experimental Physiology, EarlyView.
Abstract We examined the impact of moderate hypoxia (HYPO) on muscle activation during incremental exercise matched for both absolute and equivalent relative intensity. Fifteen active subjects (10 males, 5 females) completed two ramp incremental test and two step tests in normoxia (NORM; FiO2${F_{{\mathrm{i}}{{\mathrm{O}}_2}}}$ = 0.209) and HYPO (FiO2${

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.
