Mining For Sleep Data: An Investigation Into The Sleep Of Fly-In Fly-Out Shift Workers In The Mining Industry And Potential Solutions, Gemma Maisey
Theses: Doctorates and Masters
Shift work in the mining industry is a risk factor for sleep loss leading to impaired alertness, which may adversely impact health and safety risks. This risk is being increasingly recognised by leaders and shift workers in the mining industry, however, there is limited knowledge available on the extent of sleep loss and other potential contributing factors. Furthermore, knowledge of the efficacy of individual interventions to assist shift workers to improve their sleep, and the management of risk at an organisational level is scarce. This PhD thesis involved three studies. The first two studies involved the recruitment of 88 shift …
Exploring Demographic, Clinical And Exercise Prescription Moderators Of Resistance Exercise Effects On Objectively Measured And Patient-Reported Outcomes In Men With Prostate Cancer, Pedro Lopez Da Cruz
Exploring Demographic, Clinical And Exercise Prescription Moderators Of Resistance Exercise Effects On Objectively Measured And Patient-Reported Outcomes In Men With Prostate Cancer, Pedro Lopez Da Cruz
Theses: Doctorates and Masters
Information on specific prognostic factors such as the association of body composition with survival and tailored strategies considering demographic and clinical factors as well as the influence of exercise tolerance and compliance are required to establish targeted exercise prescription in men with prostate cancer. As a result, the purpose of this doctoral research is to: (i) investigate the role of body composition on overall survival in men with prostate cancer; (ii) determine which type of exercise/physical activity and/or dietary intervention is most effective for improving body composition outcomes in this population; (iii) examine the demographic and clinical characteristics of resistance …
Mechanisms Underpinning An Improvement In Dynamic Muscle Force Production Following A High-Intensity Warm-Up, Cody J. Wilson
Mechanisms Underpinning An Improvement In Dynamic Muscle Force Production Following A High-Intensity Warm-Up, Cody J. Wilson
Theses: Doctorates and Masters
The present research explored the mechanisms underpinning the enhancement of voluntary knee extensor torque after (1) extensive task-specific practice, and then (2) brief, intense warm-up exercise (conditioning activity; CA) as part of a complete warm-up routine. The same warm-up was completed in two Experiments (detailed below). In Experiment 1, voluntary (180⁰·s-1; T180) and electrically-evoked (isometric) knee extensor torques and electromyogram (EMG) and muscle temperature (Tm) data were recorded before and after (1) extensive task-specific practice where peak voluntary knee extensor performance was achieved, and (2) two isokinetic CAs matched for total concentric contraction time (CA60: 5 repetitions at 60⁰·s-1 vs. …
Neuromuscular Factors Contributing To Reductions In Muscle Force After Repeated, High-Intensity Muscular Efforts, Benjamin J. C. Kirk
Neuromuscular Factors Contributing To Reductions In Muscle Force After Repeated, High-Intensity Muscular Efforts, Benjamin J. C. Kirk
Theses: Doctorates and Masters
Fatigue can accumulate sufficiently to limit muscular force production during repeated, forceful muscle contractions, including those that occur in the occupational, clinical and athletic settings. Fatigue during such efforts is likely to result from disturbances to multiple processes in the nervous system and muscle. However, previous research examining the mechanisms underpinning fatigue have typically required subjects to perform low-level constant-force contractions or to repeat maximal efforts in a single set format. Such tasks do not translate well to occupational, daily living or athletic situations where high-intensity, yet submaximal, repeated efforts may be performed in work bouts (or sets) with brief …
Lower Limb Fatigue Asymmetry Of Preferred And Non-Preferred Legs After A Repeated-Sprint Test In Football Players With Previous Hamstring Injury, Cameron Lord
Theses: Doctorates and Masters
Football is the most widely played sport in the world and is thus associated with the highest total number of injuries of all sports. 12% of all football injuries are to the hamstrings, as this muscle group is subjected to constant stress during training and match play performance (Ekstrand, Hägglund, Waldén, 2011; Woods, Hawkins, Maltby, Hulse, Thomas & Hodson, 2004). While the influence of limb dominance has been extensively examined as a risk factor for injury in upper limb-dominant sports (e.g. badminton, tennis and baseball), little research has focussed on the dominance in the lower limbs. Since almost all footballers …
Monitoring Neuromuscular Fatigue In High Performance Athletes, Kristie-Lee Taylor
Monitoring Neuromuscular Fatigue In High Performance Athletes, Kristie-Lee Taylor
Theses: Doctorates and Masters
With improving professionalism of sports around the world, the volume and frequency of training required for competitive performances at the elite level has increased concurrently. With this amplification in training load comes an increased need to closely monitor the associated fatigue responses, since maximising the adaptive response to training is also reliant on avoiding the negative consequences of excessive fatigue. The rationale for the experimental chapters in this thesis was established after considering survey responses regarding current best practice for monitoring fatigue in high performance sporting environments (Chapter 3). On the basis of the results, vertical jump assessments were selected …
Fatigue, Ambulance Perspectives In A Comparative Study Between Air And Road Transports, Wayne J. Mckenna
Fatigue, Ambulance Perspectives In A Comparative Study Between Air And Road Transports, Wayne J. Mckenna
Theses: Doctorates and Masters
The study of fatigue in the health and transport sectors has predominantly been focused on night shift or day shift operations. This study has been applied to the hours of operation of Ambulance Officers who perform both night and day shifts, while also being required for on-call. The Officer on-call is on stand-by between shifts, to be available to respond for duties from the completion of one shift until the commencement of the next, usually a ten-hour shift. Studies of a similar focus have not been identified so a comparison of these specific findings has not been possible. However trends …
