Force Plate Methodologies Applied To Injury Profiling And Rehabilitation In Sport: A Scoping Review Protocol, Francisco J. Robles-Palazón, Paul Comfort, Nicholas J. Ripley, Lee Herrington, Christopher Bramah, John J. Mcmahon

Research outputs 2022 to 2026

Musculoskeletal injuries are a common health problem among sporting populations. Such injuries come with a high financial burden to the involved organisations and can have a detrimental impact on the career attainment of injured individuals. Force plates are now a common tool available to sport and exercise science and medicine professionals to enable them to profile injury risk predisposition and modulate the rehabilitation process within sporting environments. This is because contemporary force plate technology is portable and affordable and often comes with software that enables the automatic and immediate feedback of test variables to key stakeholders. However, to our knowledge, …

Proposal Of A Selection Protocol For Replication Of Studies In Sports And Exercise Science, Jennifer Murphy, Christian Mesquida, Aaron R. Caldwell, Brian D. Earp, Joe P. Warne

Articles

To improve the rigor of science, experimental evidence for scientific claims ideally needs to be replicated repeatedly with comparable analyses and new data to increase the collective confidence in the veracity of those claims. Large replication projects in psychology and cancer biology have evaluated the replicability of their fields but no collaborative effort has been undertaken in sports and exercise science. We propose to undertake such an effort here. As this is the first large replication project in this field, there is no agreed-upon protocol for selecting studies to replicate. Criticism of previous selection protocols include claims they were non-randomised …

The Impact Of Acute Calcium Intake On Bone Turnover Markers During A Training Day In Elite Male Rowers, Bronwen Lundy, Alannah K. A. Mckay, Nikita C. Fensham, Fensham, Nicolin Tee, Bryce Anderson, Aimee Morabito, Megan L. R. Ross, Marc Sim, Kathryn Ackerman, Louise M. Burke

Research outputs 2022 to 2026

Introduction: While an acute exercise session typically increases bone turnover markers (BTM), the impact of subsequent sessions and the interaction with pre-exercise calcium intake remains unclear despite the application to the ‘real life’ training of many competitive athletes. Methods: Using a randomized crossover design, elite male rowers (n = 16) completed two trials, a week apart, consisting of two 90-minute rowing ergometer sessions (Ex1, Ex2) separated by 150 minutes. Prior to each trial, participants consumed a high (CAL: ~1000 mg) or isocaloric low (CON: < 10 mg) calcium meal. Biochemical markers including parathyroid hormone: PTH; serum ionised calcium (iCa) and bone turnover markers (C-terminal telopeptide of type I collagen: β-CTX-I; osteocalcin: OC) were monitored from baseline to 3 hours post Ex2. Results: While each session caused perturbances of serum iCa, CAL maintained calcium concentrations above those of CON for most time points, 4.5 and 2.4 % higher post EX1 and EX2 respectively. The decrease in iCa in CON was associated with an elevation of blood PTH (p < 0.05) and β-CTX-I (p < 0.0001) over this period of repeated training sessions and their recovery, particularly during and after Ex2. Pre-exercise intake of calcium-rich foods lowered BTM over the course of a day with several training sessions. Conclusions: Pre-exercise intake of a calcium-rich meal prior to training sessions undertaken within the same day had a cumulative and prolonged effect on the stabilisation of blood iCa during exercise. In turn, this reduced the post-exercise PTH response, potentially attenuating the increase in markers of bone resorption. Such practical strategies may be integrated into the athlete’s overall sports nutrition plan, with the potential to safeguard long term bone health and reduce the risk of bone stress injuries.

Sport In The Face Of The Covid-19 Pandemic: Towards An Agenda For Research In The Sociology Of Sport, Adam B. Evans, Joanna Blackwell, Paddy Dolan, Josef Fahlén, Remco Hoekma, Verena Lenneis, Gareth Mcnarry

Articles

These are extraordinary times. Less because we are currently in the midst of a global pandemic; humanity has been here multiple times in the past, sometimes with even more devastating results (the ‘Black Death’ of 1346–1353, or Cocolitzli Epidemics in the 16th Century, for example). Rather, these are extraordinary times due to both the huge shutting down of industry, travel and borders, and the enormous level of coverage and discussion of the crisis through both traditional and social media formats (Stevens & Prins, 2020). Moreover, global, regional and national comparisons and discussions have become commonplace with regards to everything …

Older Athletes' Perceived Benefits Of Competition, Rylee A. Dionigi, Joseph Baker, Sean Horton

Human Kinetics Publications

Intense sport competition is typically associated with young people. Also, much of the literature on exercise for older adults focuses on benefits derived from regular physical activity, such as walking, dancing and fitness classes, and suggests that one should avoid extremely strenuous exercise. The rising phenomenon of older people competing in sport presents a challenge to these assumptions. In 2009, approximately 28,000 athletes from 95 countries gathered in Sydney, Australia to compete across 28 different sports at the World Masters Games. We interviewed 44 competitors (23 females, 21 males; aged 56-90 years; M=72) about what they gained from competing in …
