Segmental sequencing of the upper body segments in unconstrained maximum overarm throws: An implication for coaching.

Overarm throwing is an essential fundamental movement skill (FMS). Competency in throwing is critical to encourage physical activity throughout lifespan. However, the segmental sequencing characteristics of skilled throwing to achieve maximum ball release speed are unclear.

Associations between Perceptual Fatigue and Accuracy of Estimated Repetitions to Failure during Resistance Exercises.

The ability to accurately identify proximity to momentary failure during a set of resistance exercise might be important to maximise training adaptations. This study examined the association between perceptual fatigue and the accuracy of the estimated repetitions to failure (ERF). Twenty-seven males and eleven females performed sets of 10 repetitions at specific loads for the chest press and leg-press.

Estimation of Repetitions to Failure for Monitoring Resistance Exercise Intensity: Building a Case for Application.

Hackett, DA, Cobley, SP, and Halaki, M. Estimation of repetitions to failure for monitoring resistance exercise intensity: Building a case for application. J Strength Cond Res 32(5): 1352-1359, 2018-The purpose of this study was to (a) examine the accuracy of Estimated Repetitions to Failure (ERF) during resistance exercise between 2 sessions and (b) compare ERF to rating of perceived exertion (RPE) for determining proximity to momentary failure.

Accuracy in Estimating Repetitions to Failure During Resistance Exercise.

Hackett, DA, Cobley, SP, Davies, TB, Michael, SW, and Halaki, M. Accuracy in estimating repetitions to failure during resistance exercise. J Strength Cond Res 31(8): 2162-2168, 2017-The primary aim of this study was to assess the accuracy in estimation of repetitions to failure (ERF) during resistance exercise.

Variable and changing trajectories in youth athlete development: further verification in advocating a long-term inclusive tracking approach.

Athlete development through adolescence can vary greatly because of maturational processes. For example, variation can be observed in anthropometric and fitness measures with later maturing individuals "catching up" their earlier maturing peers at later time points. This study examined a methodological issue concerning how best to assess anthropometric and fitness change (i.

Constituent year: a new consideration for injury risk in Canadian youth ice hockey.

Objective: To examine if chronological age within Canadian youth ice hockey's 2-year age bands influences the proportion of injury.

Design: Retrospective secondary data analyses.

Participants: Information on 4736 injured youth ice hockey players (10-15 years old) reported by the Canadian Hospitals Injury Reporting Prevention Program (CHIRPP) and 4959 (12-15 years old) injured players reported by the Hockey Canada Insurance Database (HCID).

Relative age effects in professional German soccer: a historical analysis.

Relative age effects (RAEs) refer to the specific selection, participation and attainment (dis)advantages which occur as a result of physical and cognitive differences within annual age-grouped cohorts. The present study tracked the existence of RAEs in professional German soccer by examining RAEs in players, head coaches and referees who represented professional soccer clubs or officiated in the Bundesliga from 1963/64 to 2006/07. An additional objective was to consider the social-cultural mechanisms responsible for RAEs, so for a similar period, population and soccer participation information was also obtained.
