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 ...

Performance, cardioventilatory and perceptual responses to perceived opponent ability during head‐to‐head cycling competition

Experimental Physiology, EarlyView.
Abstract We aimed to investigate whether cycling competition influences performance and pacing compared to an individual time trial. The second aim was to determine whether performance is further influenced by deceptive or accurate augmented feedback, delivered as an opponent riding at 2% higher power outputs than a previous competitive time trial ...

The Five Factor Model of personality and evaluation of drug consumption risk

, 2017
The problem of evaluating an individual's risk of drug consumption and misuse is highly important. An online survey methodology was employed to collect data including Big Five personality traits (NEO-FFI-R), impulsivity (BIS-11), sensation seeking (ImpSS)

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 ...

Nicotine Dependence and Mental Health Among Syrian University Students: The Role of E-Cigarette Use: A Cross-Sectional Study. [PDF]

Health Sci Rep
ABSTRACT Background and Aims Nicotine dependence is a growing concern, particularly among young adults. While e‐cigarettes are marketed as smoking cessation tools, evidence suggests they may contribute to increased dependence and dual use. Additionally, nicotine use has been linked to mental health disorders, yet research exploring these associations ...

Coupling between global brain blood oxygen level‐dependent activity and cerebrospinal fluid dynamics in young endurance athletes

Experimental Physiology, EarlyView.
Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes

Evidence for early endothelial dysfunction associated with the ALDH2 rs671 gene variant: A preliminary investigation with young East Asians

Experimental Physiology, EarlyView.
Abstract Aldehyde dehydrogenase 2 (ALDH2) is a mitochondrial enzyme that plays an important role in aldehyde detoxification. A large percentage (30–50%) of the East Asian population carry a single point mutation in the ALDH2 gene (ALDH2*2 variant) that causes a severe reduction or lack of ALDH2 enzyme activity, and leads to disrupted cellular ...
