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 = …

Anxious Or Empowered? A Cross-Sectional Study Exploring How Wearable Activity Trackers Make Their Owners Feel, Jillian Ryan, Sarah Edney, Carol Maher

Research outputs 2014 to 2021

Background The market for wearable activity trackers has grown prolifically in recent years, with increasing numbers of consumers using them to track, measure, and ideally improve their health and wellbeing. Empirical evidence tends to support wearables as valid, reliable, and effective health behaviour change tools, however little research has been conducted to understand experiential aspects of the devices, particularly thier effects on users’ psychological wellbeing and affect. This study addresses this literature gap by exploring wearable users’ affective responses to their devices and how these relate to personality traits and individual differences.

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 …

Mechanical Suppression Of Osteolytic Bone Metastases In Advanced Breast Cancer Patients: A Randomised Controlled Study Protocol Evaluating Safety, Feasibility And Preliminary Efficacy Of Exercise As A Targeted Medicine, Nicolas H. 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 …

The Relationship Of Force-Time Variables Between The Loaded Squat Jump And The Midthigh Block Clean Pull, Hannah Marie Macke

Theses and Dissertations from 2018

Loaded squat jumps and midthigh block clean pulls are exercises that can be used in a strength and conditioning program to increase lower-body power. Lower-body power is critical in jumping, sprinting, and other sport specific movements. Intensities of 45-pound barbell, 20%, 40%, and 60% of a high-force, low-velocity movement were used to assess the force-time variables of the loaded squat jump and midthigh block clean pull. The current study compared peak power output as well as peak barbell velocity to find which exercise and intensity combination would be most beneficial for an athlete to increase lower-body power. A linear position …

Creating Change In Intercollegiate Athletics: The Sexual Assault Prevention Paradigm For Athletic Departments, Kristy Mccray, Sue Sutherland, Donna L. Pastore

Health and Sport Sciences Faculty Scholarship

In 2011, the Office for Civil Rights issued a “Dear Colleague Letter” instructing universities to take action regarding sexual assault on college campuses. Specifically, universities must better educate students on the prevention of sexual assault, in the hope of reducing violence against women. Previous research is inconclusive on the involvement of intercollegiate student-athletes in incidences of sexual assault; however, recent high-profile cases of sexual misconduct at universities indicate that student-athletes are not immune to this issue. The purpose of this study was to explore how sexual assault is viewed within the culture of intercollegiate athletics, including education, occurrence, and prevention. …

Friedman test compared perceptual variables across baseline, FR, and PR. Wilcoxon matched-pairs signed-ranks test evaluated EP RPE and post-EP and post-recovery RMP between FR and PR. RESULTS: Although …

Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer

International Journal of Aquatic Research and Education

According to the World Health Organization, drowning fatalities are a neglected public health issue ranked as the third most frequent cause of unintentional death by injury. Data used to record drowning incidents are acknowledged as inaccurate. Recommendations on drowning prevention based on these data are currently not informed by accurate, detailed and reliable evidence. Two modifications to current practice are proposed: 1) an Aquatic Incident Report needs to be developed as an extension of the current workplace incident report to prompt for information commonly not included in current drowning reports; and 2) National Water Safety Plans should be modified to …

Comparisons Between Movement Onset Identification Methods Used In Isometric Mid-Thigh Pull Test, Junshi Liu

Electronic Theses and Dissertations

This dissertation aimed to explore the usefulness of using force derivatives for onset detection in the isometric mid-thigh pull test. First, we examined applications of three differential calculus principles, first and second derivative, and curvature using visual detection as a reference under different baseline conditions. Second, we compared the best derivative method to a threshold-based method using visual detection as a reference. Results of our first investigation showed trivial differences between many differential calculus methods and visual detection. However, statistical differences exceeding a trivial effect was observed when instantaneous force and rate of force develop were examined. Through the first …

Femoroacetabular Impingement As A Complication Of Acetabular Fracture Fixation, David A. Zuelzer, Christopher B. Hayes, Raymond D. Wright, Stephen T. Duncan

Orthopaedic Surgery and Sports Medicine Faculty Publications

Case

We present the case of a thirteen-year-old female who sustained a posterior wall acetabular fracture dislocation. She underwent urgent closed reduction and subsequent uncomplicated open reduction and internal fixation. Post reduction computed tomography demonstrated a concentrically reduced hip joint with no evidence of femoroacetabular impingement (FAI). She subsequently healed her fracture and returned to running activities; however, one year later presented with aching pain in her thigh. Radiographs demonstrated the development of a large osseous prominence on her anterolateral femoral neck consistent with femoroacetabular impingement. Based on these findings she was evaluated by a hip preservation specialist. She subsequently …
