Effects of poling camber angle on the biomechanics of cross-country sit-skiing

open access: yesScientific Reports, 2023
Cross-country sit-skiers use double poling (DP) technique to drive the slide. The aim of this study is to analyze how poling camber angle affect the capacity of power output and biomechanical parameters of the DP process. Twenty-four non-disabled college

Poled polymers for frequency doubling of diode lasers [PDF]

open access: yesApplied Physics Letters, 1990
We report on the design and characterization of methylmethacrylate copolymers with nonlinear optical 4-alkoxy-4′-alkylsulfone stilbene sidechains, which are transparent down to 410 nm. A fairly stable, polar orientation has been obtained by means of electric field poling, resulting in a reasonably high nonlinearity (d33≤9 pm/V).

Assessment of Heart Rate Variability Thresholds from Incremental Treadmill Tests in Five Cross-Country Skiing Techniques. [PDF]

open access: yesPLoS ONE, 2016
The assessment of heart rate variability (HRV) thresholds (HRVTs) as an alternative of Ventilatory thresholds (VTs) is a relatively new approach with increasing popularity which has not been conducted in cross-country (XC) skiing yet. The main purpose of

On the Double Pole Structure of the Λ(1405) [PDF]

open access: yesProceedings of the 12th International Conference on Hypernuclear and Strange Particle Physics (HYP2015), 2017
In the last decade there have been increased theoretical and experimental evidences about the existence of two poles associated to the Λ(1405). In this contribution we summarize several recent works presenting a successful strategy to extract the position of the two Λ(1405) poles from experimental photoproduction data on the γp → KπΣ reaction at ...

Maximal Lactate Steady State and Lactate Thresholds in the Cross-Country Skiing Sub-Technique Double Poling. [PDF]

open access: yesInt J Exerc Sci, 2019
The response of blood lactate concentration (BLC) to exercise is a commonly used approach to set training intensities and to determine the anaerobic threshold, which are important in evaluation of endurance exercise performance.

Exercise economy in skiing and running

open access: yesFrontiers in Physiology, 2014
Substantial inter-individual variations in exercise economy exist even in highly trained endurance athletes. The variation is believed to be determined partly by intrinsic factors.
