Maximum Strength Benchmarks for Difficult Static Elements on Rings in Male Elite Gymnastics

open access: yesSports, 2021
On rings, in men’s artistic gymnastics, the general strength requirements for important static elements remain elusive. Therefore, the aim was to describe the relationship between a new conditioning strength test and a maximum strength test of static ...

Relationships between Unilateral Muscle Strength Qualities and Change of Direction in Adolescent Team-Sport Athletes

open access: yesSports, 2018
Previous studies have reported an association between global measures of bilateral strength and change of direction (COD) ability. Yet, little is known about the association between unilateral muscle strength qualities and COD ability.

Gravitational radiation reaction in compact binary systems: Contribution of the quadrupole-monopole interaction [PDF]

open access: yes, 2002
The radiation reaction in compact spinning binaries on eccentric orbits due to the quadrupole-monopole interaction is studied. This contribution is of second post-Newtonian order.

The Role of Extracellular Signal-Regulated Kinase Pathways in Different Models of Cardiac Hypertrophy in Rats

open access: yesBiomedicines, 2023
Cardiac hypertrophy develops following different triggers of pressure or volume overload. In several previous studies, different hypertrophy types were demonstrated following alterations in extracellular signal-regulated kinase (ERK) pathway activation ...

Chaos in the Outer Solar System [PDF]

open access: yes, 2010
We study the effect of a perturber on the energy and angular momentum of a test particle on a highly eccentric orbit. We find that both the energy and angular momentum of the test particle are adiabatic invariants when the perturber is on a circular ...

Assessment of Eccentric-Concentric Exercises Applied in Different Resistances in Terms of Strength

open access: yesTürk Spor ve Egzersiz Dergisi, 2022
The purpose of this study was to examine the effects of eccentric-concentric exercises applied at different resistances on strength parameters. Thirty-five sedentary volunteers participating in the study were divided into 4 groups by the stratified ...

A New Paradigm for Muscle Contraction

open access: yesFrontiers in Physiology, 2015
For the past 60 years, muscle contraction had been thought to be governed exclusively by the contractile filaments, actin and myosin. This thinking explained most observations for concentric and isometric, but not for eccentric muscle contractions.

Gravitational waves from eccentric compact binaries: Reduction in signal-to-noise ratio due to nonoptimal signal processing [PDF]

open access: yes, 1999
Inspiraling compact binaries have been identified as one of the most promising sources of gravitational waves for interferometric detectors. Most of these binaries are expected to have circularized by the time their gravitational waves enter the ...

Effect of Plyometric Training on Speed and Change of Direction Ability in Elite Field Hockey Players

open access: yesSports, 2018
This study investigated the effects of two plyometric training protocols on sprint and change of direction (COD) performance in elite hockey players. A parallel-group randomized controlled trial design was used and seventeen elite male and female field ...
