Assessment of Countermovement Jump: What Should We Report?

Life, 2023
The purpose of the present study was (i) to explore the reliability of the most commonly used countermovement jump (CMJ) metrics, and (ii) to reduce a large pool of metrics with acceptable levels of reliability via principal component analysis to the significant factors capable of providing distinctive aspects of CMJ performance.

Acute Effects of Sleep Extension on Fatigue, Inhibitory Control, Short‐Term Vigilance and Neuromuscular Function in Youth Elite Ice Hockey Players: A Randomised Crossover Trial

Journal of Sleep Research, EarlyView.
Scheduling a 10‐h sleep opportunity (sleep extension) in elite youth athletes increased total sleep time by approximately 1 h compared to normal sleep. Cognitive performance on an inhibitory control task (20‐min colour multisource interference task; cMSIT) improved after sleep extension, and this was accompanied by an overall lower perception of ...

Contribution of biological maturation and power of upper and lower limbs to crawl swim performance in adolescent athletes

Human Movement, 2022
Purpose There is no consensus in literature data about the influence of biological maturation (BM) on swim performance in young athletes. We analysed the relationship of BM, upper-limb power (ULP), and lower-limb power (LLP) with adolescent athletes ...

The Effect of Concurrent Activation Potentiation During Fast Stretch Shortening Cycle Activity [PDF]

, 2010
This study evaluated the effect of remote voluntary contractions (RVC) on depth jump performance. Subjects performed the depth jump in a RVC condition and a condition without RVC (NO-RVC).

Nationalist–Feminine Bifurcation: The Construction of National Morality Through Gender Regimes

Nations and Nationalism, EarlyView.
ABSTRACT This article introduces the concept of nationalist–feminine bifurcation to analyse how nationalist–populist regimes construct moral orders through gendered representations. It explores how women are simultaneously portrayed as the idealized ‘national woman’ and the excluded ‘moral threat’. Through a comparative discourse analysis of four cases—

Biomechanical Determinants of the Reactive Strength Index During Drop Jumps [PDF]

, 2018
The Reactive Strength Index (RSI) is often used to quantify drop-jump (DJ) performance; however, not much is known about its biomechanical determinants.

Spaceflight and sport science: Physiological monitoring and countermeasures for the astronaut–athlete on Mars exploration missions

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight impacts essentially every system in the human body, resulting in multisystem deconditioning that might impair the health and performance of crewmembers, particularly on long‐duration exploration missions to Mars. In this review, we apply the sport science model of athlete monitoring, testing and training to astronauts;
