Creatine Supplementation Improves Phosphagen Energy Pathway During Supramaximal Effort, but Does Not Improve Anaerobic Capacity or Performance

Frontiers in Physiology, 2019
This study aimed to investigate the effects of short-duration creatine monohydrate supplementation on anaerobic capacity (AC), anaerobic energy pathways, and time-to-exhaustion during high-intensity running.

Supramaximal Eccentric Training for Alpine Ski Racing—Strength Training with the Lifter

Applied Sciences, 2020
Eccentric muscular work plays a large role in alpine ski racing. Training with supramaximal eccentric loads (SME) is highly effective to improve eccentric strength but potentially dangerous.

Serendipitous compound action potential oscillations reveal glycolytic astrocyte and oxidative axon interstitial K+ buffering in central white matter

Experimental Physiology, EarlyView.
Abstract The principal processes that govern interstitial K+ ([K+]o) buffering in mouse optic nerve (MON), a central white matter tract, either directly consume energy (Na+–K+‐ATPase) or use transmembrane ion gradients created by energy‐dependent pumps to enable the K+ fluxes that maintain a stable [K+]o, and thus ready availability of utilisable ...

The effect of previous wingate performance using one body region on subsequent wingate performance using a different body region [PDF]

, 2017
The 30 second Wingate Anaerobic Test (WAnT) is the gold standard measure of anaerobic performance. The present investigation aimed to determine if a previous WAnT using one body region significantly affected a subsequent WAnT using a different body ...

Impaired nitric oxide‐dependent endothelial function in young male individuals with obesity before the onset of symptoms and complications

Experimental Physiology, EarlyView.
Abstract Endothelial dysfunction drives obesity‐related complications. Doppler ultrasound measurement of blood flow during 1‐min passive leg movements (PLM) is a valuable non‐invasive tool for assessing endothelial function and nitric oxide (NO)‐mediated vasodilation.

Sex and performance‐level differences in aerobic and haematological parameters among elite ski mountaineering athletes

Experimental Physiology, EarlyView.
Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...

Blood lactate clearance during active recovery after an intense running bout depends on the intensity of the active recovery [PDF]

, 2010
High-intensity exercise training contributes to the production and accumulation of blood lactate, which is cleared by active recovery. However, there is no commonly agreed intensity or mode for clearing accumulated blood lactate.

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.

The Effect of Exercise Intensity on Total PYY and GLP-1 in Healthy Females: A Pilot Study

Journal of Nutrition and Metabolism, 2017
We compared the acute response of anorexigenic signals (total PYY and GLP-1) in response to submaximal and supramaximal exercise. Nine females completed three sessions: (1) moderate-intensity continuous training (MICT; 30 min; 65%  VO2max); (2) sprint ...

Mechanisms for the Age-related Increase in Fatigability of the Knee Extensors in Old and Very Old Adults [PDF]

, 2018
The mechanisms for the age-related increase in fatigability during high-velocity contractions in old and very old adults ({greater than or equal to}80 yrs) are unresolved. Moreover, whether the increased fatigability with advancing age and the underlying
