Accelerometry-based variables in professional soccer players: comparisons between periods of the season and playing positions
(TERMEDIA PUBLISHING HOUSE LTD., 2020)
The aim of this study was to provide reference data of variation in external training loads for weekly periods within the annual season. Specifically, we aimed to compare the weekly acute load, monotony, and training strain ...
Baroreflex Modulation During Acute High-Altitude Exposure in Rats
(Frontiers Media, 2020)
Baroreflex (BR) control is critically dependent of sympathetic and parasympathetic modulation. It has been documented that during acute hypobaric hypoxia there is a BR control impairment, however, the effect of a natural ...
Physical fitness profile in elite beach handball players of different age categories
(Edizioni Minerva Medica S.p.A., 2020-12)
BACKGROUND: The aims of this study were to compare anthropometric and fitness variables of high-level beach handball players across Under-19 (U-19), Under-21 (U-21) and senior male categories, and between male and female ...
Psychobiological Changes during National Futsal Team Training Camps and Their Relationship with Training Load
(MDPI, 2020-03-02)
The aim of this study was two-fold: (1) to analyze the within-week variations of heart rate, session-rated of perceived exertion (sRPE), total distance, distance in 8.0-11.99 km/h(-1), recovery distance in 12.0-17.99 ...
Peaking for the World Para Athletics Championships: Case study of a World Champion female Paralympic shot putter
(España. Universidad de Alicante, 2020-06)
Tapering is used to maximize performance and reduce fatigue levels before athletic competitions. However, scientific evidence regarding Paralympic athletes is scarce. Moreover, no study has assessed the effects of tapering ...
PT-symmetric phonon laser under gain saturation effect
(The Optical Society, 2020-07-20)
As an analog of optical laser, phonon laser has potential applications in various areas. We study a type of phonon laser implemented by two coupled micro-cavities, one of which carries optical gain medium. The phonon laser ...
Mechanical oscillations frozen on discrete levels by two optical driving fields
(American Physical Society, 2020-07-20)
We report a synchronization phenomenon which is simulated with an optomechanical system driven by two equally strong fields with different frequencies. Once the frequencies of the driving fields are properly matched, the ...
Phonon maser stimulated by spin postselection
(American Physical Society, 2020-06-09)
In a sequence of single spins interacting longitudinally with a mechanical oscillator, and using the micromaser model with random injection, we show that after an appropriate postselection of each spin, a phonon laser ...
Cardiac remodeling and arrhythmogenesis are ameliorated by administration of Cx43 mimetic peptide Gap27 in heart failure rats
(Springer Nature, 2020)
Alterations in connexins and specifically in 43 isoform (Cx43) in the heart have been associated with a high incidence of arrhythmogenesis and sudden death in several cardiac diseases. We propose to determine salutary ...
Methodological characteristics and future directions for plyometric jump training research: A scoping review update
(WILEY, 2020)
The aim of this scoping review was a) to update a previous review on the main methodological characteristics and shortcomings in the plyometric jump training (PJT) literature, and b) to recommend, in light of the identified ...
