Spinal excitability is increased in the torque-depressed isometric steady state following active muscle shortening [PDF]

open access: yesRoyal Society Open Science, 2017
Torque depression (TD) is the reduction in steady-state isometric torque following active muscle shortening when compared with a purely isometric contraction at the same muscle length and level of activation.

Elliptical concentrators [PDF]

open access: yesApplied Optics, 2006
Nonimaging optics is a field devoted to the design of optical components for applications such as solar concentration or illumination. In this field, many different techniques have been used to produce optical devices, including the use of reflective and refractive components or inverse engineering techniques.

Muscle fiber conduction velocity is more affected after eccentric than concentric exercise [PDF]

open access: yes, 2010
It has been shown that mean muscle fiber conduction velocity (CV) can be acutely impaired after eccentric exercise. However, it is not known whether this applies to other exercise modes.

THE INVESTIGATION OF THE EFFECTS OF ECCENTRIC EXERCISES ON SOME MOTORIC CHARACTERISTICS OF YOUTH SOCCER PLAYERS

open access: yesSpormetre Beden Eğitimi ve Spor Bilimleri Dergisi, 2019
There are various training programs to improve sportive performance so that soccer-specific technical skills can be realized more easily. The aim of the EG is to examine the effect of the training program that including eccentric and concentric ...

Relationship between sprint and vertical jump force-time metrics in elite male professional futsal players [PDF]

open access: yesJournal of Applied Sports Sciences
While sprinting capabilities are crucial for success in futsal, there is a lack of research on how they relate to countermovement vertical jump (CMJ) force-time metrics during both the eccentric and concentric phases of the movement. Thus, the purpose of

Hyperbolic Concentration, Anti-concentration, and Discrepancy

open access: yes, 2020
Chernoff bound is a fundamental tool in theoretical computer science. It has been extensively used in randomized algorithm design and stochastic type analysis. Discrepancy theory, which deals with finding a bi-coloring of a set system such that the coloring of each set is balanced, has a huge number of applications in approximation algorithms design ...

Concentration of Herpesviruses [PDF]

open access: yesJournal of Virology, 1973
A method has been developed for the concentration of herpesviruses by negative pressure ultrafiltration through dialysis tubing. The procedure results in high titer concentrates of unaggregated, morphologically intact viral particles with a virtually quantitative recovery of infectivity.

Modifiability of residual force depression in single muscle fibers following uphill and downhill training in rats

open access: yesPhysiological Reports, 2021
Following active muscle shortening, steady‐state isometric force is less than a purely isometric contraction at the same muscle length and level of activation; this is known as residual force depression (rFD).

The Eccentric Phase in Unilateral Resistance Training Enhances and Preserves the Contralateral Knee Extensors Strength Gains After Detraining in Women: A Randomized Controlled Trial

open access: yesFrontiers in Physiology, 2022
The current randomized controlled study investigated whether or not the inclusion of the eccentric phase in resistance training favors the contralateral strength gains after different unilateral protocols, and whether such gains are retained after ...
