Reliability and validity of wearable microtechnology devices in team sports

This project looks at the validity and reliability of global navigation satellite systems throughout movements commonplace to field-based team sports. Specifically, we are looking to discover if the validity and reliability is consistent over time eg multiple sessions.

Understanding the adolescent athlete

This program of research will investigate factors that impact adolescent athletes' performance and injury rates. Studies will look to quantify the psychological and physical loads that adolescent athletes experience and the impact of these loads on performance and injury. Further, factors that may build resilience to these loads will be investigated. Ultimately, this program of research will assist practitioners in knowing what loading factors may affect performance and injury, and how to best manage these loads in adolescent athletes.

Can we use wearable microtechnology devices to monitor neurological changes and injury risk post-concussion in team sport players?

Sports-related concussion, a transient trauma induced alteration in mental status, accounts for approximately 1.6 to 3.8 million reported cases annually in the United States alone.

Current protocols used to diagnose and determine return to play typically rely on subjective interpretation, with poor sensitivity one week post-injury. Due to the issues with these assessments, it is suggested that players return to their respective sports with lingering neuromuscular deficits.

Indeed, lab assessments have highlighted poorer neuromuscular control in previously concussed athletes that persist for months following a concussive event. However, these assessments are time consuming and require access to specialised equipment that make them redundant for many practitioners. It has been proposed that the use of microtechnology, specifically inertial measurement units (IMUs) may aid in objectively assessing alterations in gait parameters upon return to play. The studies in this PhD aim to assess validity and reliability of thoracic placed IMUs and their place in assessing motor deficits post-concussion.

The use of triaxial accelerometry for measuring stride parameters and vertical stiffness in team sport athletes

Inertial measurement units (IMUs) are used for running gait analysis in a variety of sports. These sensors have been attached at various locations to capture stride data. However, it is unclear if different placement sites affect the derived outcome measures. These studies will examine the validity and reliability of accelerometers placed at various sites for the measurement of discrete stride parameters in addition to the impact of fatigue on vertical stiffness and stride variables.

Acute responses and chronic adaptations to high-intensity interval training methods used during team-sport conditioning

This program of research will investigate the acute and chronic effects of high-intensity interval training methods used during team-sport conditioning on physiological, neuro-muscular, and musculoskeletal responses. It will demonstrate how different methods can influence the responses to training, and how exercise variables can be manipulated to enhance performance and mitigate fatigue.

Application of an instantaneous work-rate measure using external load in elite football players

This project will examine the measurements collected using wearable microtechnology including GPS and heart rate metrics and the relationship to measurements of oxygen uptake. This will be investigated during a football drill designed to simulate movements which occur during training and competition. The research will investigate which metrics commonly used in training load monitoring have the strongest relationship to oxygen uptake and how this varies at different exercise intensities. The research will then examine these metrics within regular training and competition in elite football players. These metrics will be examined across different training drills and in relation to contextual variables which occur during competition.

The use of blood flow restriction training in high performance athletes

Blood Flow Restriction (BFR) Training has been a popular training method used within the hypertrophy and rehabilitation setting since the initial idea was developed by Dr Yoshiaki Sato, the creator of KAATSU. However, in recent years it has started to be involved within High Performance Sport settings, as an alternative method for athletes who are unable to perform traditional resistance training methods due to an injury, or athletes who are wishing to gain an alternative stimulus. However, recent research in BFR has shifted towards the use of BFR within athlete preparation and recovery. This program of research aims to demonstrate the use of BFR training in High Performance Athletes, with this project being based at the Tasmanian Institute of Sport (TIS).

Quantifying the effect of mental fatigue on physical performance in elite Australian Rules Football athletes

Mental fatigue negatively affects endurance exercise performance and skill execution, two key components of Australian Rules football performance. This project aims to understand if athletes experience mental fatigue and if it does affect physical performance in matches and training.
