Experimental validation of the 3-parameter critical power model in cycling.

Eur J Appl Physiol 2019 Jan 29. Epub 2019 Jan 29.

Department of Molecular and Translational Medicine, University of Brescia, Viale Europa 11, 25123, Brescia, Italy.

Purpose: The three-parameter model of critical power (3-p) implies that in the severe exercise intensity domain time to exhaustion (T) decreases hyperbolically with power output starting from the power asymptote (critical power, ẇ) and reaching 0 s at a finite power limit (ẇ) thanks to a negative time asymptote (k). We aimed to validate 3-p for short T and to test the hypothesis that ẇ represents the maximal instantaneous muscular power.

Methods: Ten subjects performed an incremental test and nine constant-power trials to exhaustion on an electronically braked cycle ergometer. Read More

The skeletal muscle fiber: a mechanically sensitive cell.

Eur J Appl Physiol 2019 Feb 5;119(2):333-349. Epub 2019 Jan 5.

Department of Health, Sport, and Exercise Sciences, University of Kansas, Lawrence, KS, 66045, USA.

The plasticity of skeletal muscle, whether an increase in size, change in metabolism, or alteration in structural properties, is in a continuous state of flux largely dependent upon physical activity. Much of the past research has expounded upon these ever-changing aspects of the muscle fiber following exercise. Specifically, endocrine and paracrine signaling have been heavily investigated lending to much of the past literature comprised of such endocrinological dynamics following muscle activity. Read More

Ramp and step increases in shear stress result in a similar magnitude of brachial artery flow-mediated dilation.

Eur J Appl Physiol 2019 Jan 2. Epub 2019 Jan 2.

Cardiovascular Stress Response Laboratory, School of Kinesiology and Health Studies, Queen's University, 28 Division Street, Kingston, ON, K7L 3N6, Canada.

Purpose: There is evidence that the endothelium is responsive to both the rate and magnitude of increases in shear stress. However, whether flow-mediated dilation stimulated by sustained increases in shear stress (SS-FMD) is rate sensitive in humans is unknown. The purpose of this investigation was to test whether ramp (gradual) and step (instantaneous) increases in shear stress elicit disparate SS-FMD. Read More

Intermittent sprint performance in the heat is not altered by augmenting thermal perception via L-menthol or capsaicin mouth rinses.

Eur J Appl Physiol 2018 Dec 22. Epub 2018 Dec 22.

Environmental Extremes Laboratory, University of Brighton, Eastbourne, UK.

Purpose: Cooling sensations elicited by mouth rinsing with L-menthol have been reported as ergogenic. Presently, responses to L-menthol mouth rinsing during intermittent sprint performance (ISP) in the heat are unknown and the impact of increased thermal perception on ISP via capsaicin has also not been quantified. This experiment aimed to identify whether eliciting cooling/warming sensations via L-menthol/capsaicin would alter ISP in the heat. Read More
