Velocity-Based Training: Monitoring, Implementation And Effects On Strength And Power, Henry G. Banyard

Theses: Doctorates and Masters

Traditionally, resistance training has been prescribed using percent-based training (PBT) methods that use the loads relative to a maximal load lifted for one repetition (1RM). However, PBT does not take into account possible day-to-day fluctuations in performance that may occur from physical or psychological stressors. One approach to address this limitation is to monitor velocity changes during resistance training, based on research showing that declines in velocity are highly correlated with fatigue. Therefore, velocity-based training (VBT) methods are proposed to provide a more objective method to modify resistance training sessions based on individual differences in day-to-day performance and the rate …

Time-To-Event Analysis For Sports Injury Research Part 1: Time-Varying Exposures, Rasmus Oestergaard Nielsen, Michael Lejbach Bertelsen, Daniel Ramskov, Merete Møller, Adam Hulme, Daniel Theisen, Caroline F. Finch, Lauren Victoria Fortington, Mohammad Ali Mansournia, Erik Thorlund Parner

Research outputs 2014 to 2021

BACKGROUND: ‘How much change in training load is too much before injury is sustained, among different athletes?’ is a key question in sports medicine and sports science. To address this question the investigator/practitioner must analyse exposure variables that change over time, such as change in training load. Very few studies have included time-varying exposures (eg, training load) and time-varying effect-measure modifiers (eg, previous injury, biomechanics, sleep/stress) when studying sports injury aetiology.

AIM: To discuss advanced statistical methods suitable for the complex analysis of time-varying exposures such as changes in training load and injury-related outcomes.

CONTENT: Time-varying exposures and time-varying effect-measure …

Time-To-Event Analysis For Sports Injury Research Part 2: Time-Varying Outcomes, Rasmus Oestergaard Nielsen, Michael Lejbach Bertelsen, Daniel Ramskov, Merete Møller, Adam Hulme, Daniel Theisen, Caroline F. Finch, Lauren Victoria Fortington, Mohammad Ali Mansournia, Erik Thorlund Parner

Research outputs 2014 to 2021

BACKGROUND: Time-to-event modelling is underutilised in sports injury research. Still, sports injury researchers have been encouraged to consider time-to-event analyses as a powerful alternative to other statistical methods. Therefore, it is important to shed light on statistical approaches suitable for analysing training load related key-questions within the sports injury domain.

CONTENT: In the present article, we illuminate: (i) the possibilities of including time-varying outcomes in time-to-event analyses, (ii) how to deal with a situation where different types of sports injuries are included in the analyses (ie, competing risks), and (iii) how to deal with the situation where multiple subsequent injuries …

Considerations When Assessing Endurance In Combat Sport Athletes, Oliver R. Barley, Dale W. Chapman, Stuart N. Guppy, Chris R. Abbiss

Research outputs 2014 to 2021

Combat sports encompass a range of sports, each involving physical combat between participants. Such sports are unique, with competitive success influenced by a diverse range of physical characteristics. Effectively identifying and evaluating each characteristic is essential for athletes and support staff alike. Previous research investigating the relationship between combat sports performance and measures of strength and power is robust. However, research investigating the relationship between combat sports performance and assessments of endurance is less conclusive. As a physical characteristic, endurance is complex and influenced by multiple factors including mechanical efficiency, maximal aerobic capacity, metabolic thresholds, and anaerobic capacities. To assess …

Role Of Lactic Acidosis As A Mediator Of Sprint-Mediated Nausea, Robert J. Merrells, Ashely J. Cripps, Paola T. Chivers, Paul A. Fournier

Research outputs 2014 to 2021

This study aims to determine whether there is a relationship between nausea level and lactic acidosis during recovery from sprinting. In all, 13 recreationally active males completed a 60 s bout of maximal intensity cycling. Prior to and for 45 min following exercise, blood pH, pCO₂, and lactate levels were measured together with nausea. In response to sprinting, nausea, lactate, and H⁺ concentrations increased and remained elevated for at least 10 min (p < .001), whereas pCO₂ increased only transiently (p < .001) before falling below pre‐exercise levels (p < .001), with all these variables returning toward pre‐exercise levels during recovery. Both measures of nausea adopted for analyses (nausea profile, NP; visual analogue scale, VAS), demonstrated significant repeated measures correlation (rmcorr) post‐exercise between nausea and plasma lactate (VAS and NPr_rm> 0.595, p < .0001) and H⁺ concentrations (VAS and NPr_rm> 0.689, p < .0001), but an inconsistent relationship with pCO₂ (VAS r_rm = …

Finding Your Balance: An Investigation Of Recovery–Stress Balance In Vocational Dance Training, Peta Blevins, Shona Erskine, Luke Hopper, Gene Moyle

Research outputs 2014 to 2021

Professional dance careers require years of intensive training. Stress experienced during training must be balanced with adequate recovery to prevent overtraining and burnout. Little is known, however, about how dancers achieve recovery–stress balance. This study examined dancers’ recollection of stress and recovery during their vocational dance training to identify potential stressors and recovery behaviors in vocational dance training. Twelve current and ex-professional ballet (n=4) and contemporary dancers (n=8) participated in the study. Four general dimensions, based on the extant overtraining literature in athletes, were identified: dance culture, intrapersonal, interpersonal, and situational factors. Cultural norms, health factors related to injury and …

Analysis Of Perceptual-Motor Calibration Processes In Indoor Climbing, Andrew Stephen Walsh

Theses: Doctorates and Masters

This research programme examines how people perceive maximal reach-and grasp-ness in climbing, and as such these questions will be limited to climbing.

Is experienced gained from performing daily submaximal reaching sufficient for the accurate perception of maximal horizontal reaching affordances in rock climbing?

How is perception of maximal horizontal boundary of reach-and grasp-ness affected by: hold size, body position, additional load, or fatigue.

How will inducing fatigue affect how a participant calibrates distance and their movement economy?

The Influence Of Barbell And Body Position On Force-Time Characteristics In The Isometric Mid-Thigh Pull, Stuart Nathan Guppy

Theses: Doctorates and Masters

Publication 1: The Isometric Mid-Thigh Pull: A Review and Methodology – Part 1 Isometric tests are commonly used to monitor physical qualities that underpin athletic performance. As single-joint laboratory-based tests display poor relationships to the multi-joint movements found in sport, multi-joint isometric tests like the isometric midthigh pull (IMTP) are commonly used instead. Force-time characteristics in these multijoint tests typically display stronger relationships to dynamic performance, particularly in the case of the isometric mid-thigh pull. As such this review focuses on the relationships between force-time characteristics in the IMTP and dynamic athletic performance.

The Application Of Maximal Mean And Critical Speed And Metabolic Powers For The Quantification Of External Load In Soccer, Cameron Nicholas Lord

Theses: Doctorates and Masters

In Association football, often referred to as “soccer”, competitive match play is typically known to represent the greatest physical demand that players experience. The demands associated with match running performance may impact training outcomes and injury risk. As a result, practitioners evaluate these demands to ensure that performance is optimised. To assist in this process, global positioning systems (GPS) are typically used to quantify displacement variables and, more recently, the interaction between running speed and acceleration. However, traditional player monitoring methods tend to apply identical and somewhat arbitrary displacement, velocity and acceleration bands to describe movement “intensity”, and thus to …

Comparison Of Subsequent Injury Categorisation (Sic) Models And Their Application In A Sporting Population, Liam A. Toohey, Michael K. Drew, Lauren V. Fortington, Miranda J. Menaspa, Caroline F. Finch, Jill L. Cook

Hart, Daniel A. Galvão, Christobel Saunders, Dennis R. Taaffe, Kynan T. Feeney, Nigel A. Spry, Daphne Tsoi, Hilary Martin, Raphael Chee, Tim Clay, Andrew D. Redfern, Robert U. Newton

Research outputs 2014 to 2021

BACKGROUND: Skeletal metastases present a major challenge for clinicians, representing an advanced and typically incurable stage of cancer. Bone is also the most common location for metastatic breast carcinoma, with skeletal lesions identified in over 80% of patients with advanced breast cancer. Preclinical models have demonstrated the ability of mechanical stimulation to suppress tumour formation and promote skeletal preservation at bone sites with osteolytic lesions, generating modulatory interference of tumour-driven bone remodelling. Preclinical studies have also demonstrated anti-cancer effects through exercise by minimising tumour hypoxia, normalising tumour vasculature and increasing tumoural blood perfusion. This study proposes to explore the promising …

The Current State Of Subjective Training Load Monitoring—A Practical Perspective And Call To Action, Joseph O. C. Coyne, G. Gregory Haff, Aaron J Coutts, Robert U. Newton, Sophia Nimphius

Research outputs 2014 to 2021

This commentary delivers a practical perspective on the current state of subjective training load (TL) monitoring, and in particular sessional ratings of perceived exertion, for performance enhancement and injury prevention. Subjective measures may be able to reflect mental fatigue, effort, stress, and motivation. These factors appear to be important moderators of the relationship TL has with performance and injury, and they also seem to differ between open and closed skill sports. As such, mental factors may affect the interaction between TL, performance, and injury in different sports. Further, modeling these interactions may be limited due to the assumption that an …

Research outputs 2014 to 2021

The aim of this study was to evaluate the effect of a repeated sprint ability (RSA) test on the contractile properties of the muscles in elite futsal players. A total of 20 elite players completed the RSA test (7 × 30 m), and the contractile response from the rectus femoris (RF) and biceps femoris (BF) of both legs were analysed pre and post through tensiomyography. There was a significant increment in 30-m times from the third sprint onwards (p < 0.05). The percent decrement in sprint ability (RSA) with respect to the first sprint was significantly higher in the last sprint. The players did not show evidence of lateral asymmetry in any of the muscle groups analysed after the RSA test (p > 0.05). Following the RSA test there was a significant reduction in the delay time (Td) in RF, a significant decrement …

Hif Prolyl Hydroxylase Inhibition Protects Skeletal Muscle From Eccentric Contraction-Induced Injury, Andrew N Billin, Samuel E Honeycutt, Alan V Mcdougal, Jaclyn P Kerr, Zhe Chen, Johannes M Freudenberg, Deepak K Rajpal, Guizhen Luo, Henning Fritz Kramer, Robert S Geske, Frank Fang, Bert Yao, Richard V Clark, John Lepore, Alex Cobitz, Ram Miller, Kazunori Nosaka, Aaron C Hinken, Alan J Russell

Research outputs 2014 to 2021

BACKGROUND: In muscular dystrophy and old age, skeletal muscle repair is compromised leading to fibrosis and fatty tissue accumulation. Therefore, therapies that protect skeletal muscle or enhance repair would be valuable medical treatments. Hypoxia-inducible factors (HIFs) regulate gene transcription under conditions of low oxygen, and HIF target genes EPO and VEGF have been associated with muscle protection and repair. We tested the importance of HIF activation following skeletal muscle injury, in both a murine model and human volunteers, using prolyl hydroxylase inhibitors that stabilize and activate HIF.

METHODS: Using a mouse eccentric limb injury model, we characterized the protective effects …

The Constituent Year Effect: Relative Age Disparities In Australian Masters Track And Field Athletic Participation, Nikola Medic, Jasmine Lares, Bradley W. Young

Research outputs 2014 to 2021

The constituent year effect, a source of relative age disparities, in masters sport has been demonstrated mainly amongst North American samples. Thus, the purpose of this study was to examine whether a participation-related constituent year effect exists among athletes (n = 6492) competing in Australian Masters Athletics competitions between 2000 and 2014. The results indicated that a participation-related constituent year effect was observed as the likelihood of participating was significantly higher for masters athletes in their first and second constituent year of any five-year age category (p < 0.0001) and was lower when they were in the fourth or fifth constituent year. The results also indicated this effect is influenced by gender and age. Specifically, the effect was significant for both male (p < 0.0001) and female (p < 0.001) masters athletes; as well during the third, sixth, seventh, and eighth + decades of life (all ps < 0.001). These data demonstrate that despite masters sport being an avenue for promotion of participation and overall health, there is potential for improving how competitive organizational strategies are implemented given the recurring intermittent patterns of participation associated with five-year age brackets which are likely to compromise benefits.

The Mechanics Of Front Leg Loading During Cricket Fast Bowling: Delivery Variations, Spell Demands, And The Effects Of Strength Training, Samuel J. Callaghan

Theses: Doctorates and Masters

The goal of fast bowling in cricket is to dismiss a batsman for as few runs as possible. To assist this goal, fast bowlers will attempt to maximise ball release velocity (BRV) to decrease the decision-making and stroke execution time of the opposing batsmen. Fast bowlers will also employ various delivery lengths (i.e. short, good and full) to assist in affecting a batsman’s stroke execution.

Several issues remain to be addressed with regards to the biomechanical assessment of fast bowling. This is particularly evident when analysing fast bowling performance (i.e. BRV), the implications of front foot loading (i.e. vertical and …
