Improving the measurement of TMS-assessed voluntary activation in the knee extensors

The present study was designed to test the accuracy, validity, reliability and sensitivity of the main outcomes of alternative methods for the measure of TMS-assessed voluntary activation (VATMS) in the knee extensors. Ten healthy recreationally active males (24 ± 5 years) completed a neuromuscular assessment protocol (NMA) before and immediately after a fatiguing isometric exercise, …

The AccuKick football passing test: Reliability, discriminate ability, and correlations with athletic capabilities

AccuKick is a new football passing test that measures passing accuracy and time to ball release (TTR) under time constrains. We examined AccuKick’s test-retest reliability, discriminate ability, and its relationships with jumping, sprinting, change-of-direction and intermittent running tests, among adolescent football players. Forty-seven players of different age groups participated in this study: U19 (n = …

Perceived Impact: A Mechanism Underpinning the End-Spurt and U-Shape Pacing Patterns

The end-spurt and U-shape reflect common pacing patterns across numerous fields. To date, however, the literature lacks a parsimonious, applicable account for these effects. Here, I propose a novel causal explanation for these effects – perceived impact. As one perceives his/her actions to better affect progress within a task, the higher one’s motivation. The higher …

The Effect of Narcissistic Admiration and Rivalry on Mental Toughness in Thai Athletes

Objective. Are narcissistic athletes mentally tough? Despite the existing literature supporting the view that narcissistic grandiosity is positively related to mental toughness, no efforts have been made to understand how the agentic and antagonistic sides of narcissism are associated with mental toughness. Here we examine the effect of narcissistic admiration and rivalry on self-reported and …

Dose response association of objective physical activity with mental health in a representative national sample of adults: a cross-sectional study

Although higher physical activity (PA) levels are associated with better mental health, previous findings about the shape of the dose–response relationship between PA and mental health are inconsistent. Furthermore, this association may differ according to sedentary levels. We investigated the cross-sectional dose-response associations between objectively measured PA and mental health in a representative national sample …

Exercise practice associates with different brain rhythmic patterns during vigilance

Purpose: To investigate brain oscillatory patterns underlying prolonged attentional performance as a function of cardiorespiratory fitness in healthy young adults. Design: Cross-sectional study. Method: Two groups of participants (25 higher-fit and 25 lower-fit) were compared in terms of reaction time (RT) performance, tonic electroencephalographic (EEG) overall dynamics, and event-related spectral perturbation (ERSP) in a 60’ …

Mechanical Misconceptions: Have we lost the “mechanics” in “biomechanics”?

In theory, everything in biomechanics stems from two disciplines, physics and biology. While a number of papers, editorials, letters to the editor, and even a review have addressed the misapplication of mechanical principles, the misapplication of the basic principles of physics in the field of biomechanics continues. There are three principles, specifically, that have been …

Objectively measured physical activity and sedentary behaviors in a representative sample of Canadian adults with chronic disease(s) : a cross-sectional study

Background: Physical activity and sedentary behaviors are major determinants of quality of life in adults with one or more chronic disease(s). However, there are no Canadian representative population-based studies investigating objectively measured physical activity and sedentary behaviors in adults with and without chronic disease(s). Objective: To compare objectively measured physical activity and sedentary behaviors in …

Examining the influence of skin tone on playing position in the Premier and English Football Leagues

Within the present manuscript we explore the role of skin tone on playing position within English football’s top four professional leagues. Player data (N = 4,515) was collected across five seasons (2010-2015). Results indicate that in general, darker skin toned players are more likely to operate within peripheral rather than central positions. Using both one …

Daily objective physical activity and sedentary time in adults with COPD using spirometry data from Canadian Measures Health Survey

Chronic obstructive pulmonary disease (COPD) is expected to be the third leading cause of premature death and disability in Canada and around the world by the year 2020. The study aims to compare objective physical activity (PA) and sedentary time in a population-based sample of adults with chronic obstructive pulmonary disease (COPD) and comparison a …
