Holland, Justin J. "The role of hydration in motorsport performance." Thesis, University of Queensland, 2018.

Find full text

Abstract:

Motorsport is a physically and cognitively demanding sport, where driver-athletes compete in compensable environments. The term ‘driver-athlete’ acknowledges that drivers possess certain unique skills that have been developed through training and practice that allows them to compete for a prize, recognition and admiration from peers and the public. Hydration and physical fitness are two important variables that may assist in a driver’s preparation for a race and subsequent health, safety and performance. This thesis has three main research studies that aim to understand the associated demands

Abstract:

Many problems related to balance, strength and physical training for the elderly population remain unresolved. The purpose of this work was to investigate the influence of knee strength on static balance in the elderly and to determine specific physical training programs which could affect strength and balance. The correlation between balance and strength for the elderly population was studied and compared with that of the young population. The contribution of appropriately designed physical exercises to improve balance and strength for the elderly was also evaluated.

McCoy, Michael. "Determinants of ventilation during exercise." Thesis, 1990. https://vuir.vu.edu.au/15752/.

Full text

Abstract:

The anaerobic threshold hypothesis suggests a causal link between the ventilatory and lactate responses to exercise. If such a causal link exists, it should be evident in all subjects, regardless of fitness levels. There is also evidence to support a role of potassium in the regulation of ventilation. Further, numerous authors have suggested that submaximal threshold indices can accurately predict performance. The following conclusions were drawn from the results of this thesis:(1) changes in ventilation during exercise are regulated by a number of inputs including La- and K+, both of which ar

Abstract:

The increased time-demands imposed on modern society means that many people don’t meet nightly sleep recommendations. However, despite the obvious importance of sleep for the maintenance of good health, the effects of sleep loss are remarkably understudied. The consequences of sleep loss on aspects of metabolic health are becoming more apparent, with detrimental changes to glucose tolerance, insulin sensitivity, and an increased risk of numerous metabolic conditions being reported. Comparatively, the underlying mechanisms that lead to these changes are not well characterised, but may include c

Abstract:

Chronic heart failure (CHF) patients are limited in functional capacity by muscle fatigue and breathlessness. The effects of resistance training on muscle strength and endurance and functional aerobic capacity were evaluated in 9 men (63 ± 11 years; mean ± s.d) with CHF (LVEF 26 ± 6%). Training comprised bilateral upper and lower body resistance exercises for 3 sessions per week for 11 weeks on hydraulic equipment. Before and after training, patients underwent assessment of strength and endurance (Merac isokinetic system), functional 6-minute walk and peak aerobic (V02peak) capacity. Ba

Abstract:

Prolonged exhaustive submaximal exercise in humans induces marked metabolic changes, but little is known about effects on muscle Na+, K+ATPase activity and sarcoplasmic reticulum (SR) Ca2+ regulation. We therefore investigated whether these processes were impaired during cycling exercise at 74.3±1.2% v02 peak (mean±SEM) continued until fatigue, in eight healthy subjects (v02 peak 3.93±0.69 l.min-1). A vastus lateralis muscle biopsy was taken at rest, at 10 and 45 min of exercise and at fatigue. Muscle was analysed for in-vitro Na+,K+ ATPase activity (maximal K+ -stimulated 3-0-methylflu

Abstract:

It is well documented that regular endurance exercise induces skeletal muscle mitochondrial biogenesis. However, the optimal training stimulus and nutritional intervention for which to maximize mitochondrial adaptations to endurance exercise is not well known. Developments in molecular techniques now permit the examination of the cell signalling responses to acute exercise therefore increasing our understanding of how manipulation of the training protocol and nutrient availability may enhance the training stimulus to a given bout of exercise. The primary aim of this thesis is to therefore char

Medved, Ivan. "The effects of N-acetylcysteine infusion on performance, glutathione and ion regulation during voluntary exercise in humans." Thesis, 2005. https://vuir.vu.edu.au/15641/.

Full text

Abstract:

The production of reactive oxygen species in skeletal muscle has been linked with muscle fatigue. Infusion of the antioxidant compound 7V-acetylcysteine (NAC) reduced fatigability in electrically evoked human muscle contractions, but numerous adverse reactions were reported. No studies have investigated NAC infusion effects during voluntary exercise in humans. This thesis investigated whether an NAC infusion protocol that was modified to minimise these adverse reactions, would augment time to fatigue, enhance glutathione availability and enhance potassium (K+) regulation during voluntary fati

Abstract:

Childhood and adolescence are time periods characterised by the rapid growth and development of the skeletal system. The timing and magnitude of skeletal development varies considerably between individuals however, environmental factors may make significant contributions to the variance in bone mass. To optimise the development of bone it is important to identify and promote factors that may have a positive effect on bone mass accrual. Two lifestyle factors that may enhance bone mass accural are calcium and exercise. The focus of this thesis was to investigate bone mass accural in children and

Abstract:

This study developed a multi-stage step test for the prediction of VO2peak in people with low tolerance to exercise. The aim was to develop a simple and safe protocol, that accounted for differences in statute height and is suitable for use in exercise rehabilitation. The step height (Hstep) was determined as 0.125 x the subject's height (Hsubject. People undergoing physical and psychological rehabilitation (n=23) were compared to a normal group (n=28), not undergoing rehabilitation. The symptom-limited step test began at a low cadence (14 cycles per minute, c.min-1) and increased by 4 c.min-1

Abstract:

The sarcoplasmic reticulum (SR) regulates intracellular calcium and therefore largely determines the rates of contraction and relaxation in skeletal muscle. However, little is known about SR function in human skeletal muscle. This thesis therefore investigated several factors that could potentially influence SR function in human skeletal muscle, including the effects of acute exercise, training status, chronic inactivity and the influence of muscle fibre type. A final study investigated the effects of an immunosuppressive drug on SR function in rat skeletal muscle.

Abstract:

Muscle contractions and exercise have been shown to potently stimulate muscle glucose uptake via molecular mechanisms that are different to insulin-stimulated glucose uptake. Importantly, although insulin-stimulated glucose uptake is diminished in people with type 2 diabetes, the ability for contractions or exercise to stimulate muscle glucose uptake appears to be preserved. Activating this exercise signalling pathway with novel drugs could theoretically bypass the defective insulin-signalling pathway and lower blood glucose levels in insulin-resistant individuals.

Abstract:

This thesis investigated the role respiratory muscle work has on locomotor and respiratory muscle oxygen (O2) utilisation during multiple sprint work. To measure O2 delivery and uptake in real time, near-infrared spectroscopy (NIRS) can be used. However, there are inconsistent methods of smoothing and determining peaks and nadirs from the NIRS signal. Therefore, the aim of study 1 was to examine the effects of different methodologies commonly used in the literature on the determination of peaks and nadirs in the vastus lateralis deoxyhaemoglobin (HHbVL) signal.

Abstract:

Lung transplant (LTx) recipients have poor exercise tolerance, which persists in spite of the restoration of near normal lung function. This suggests that the exercise limitation is related to defects in skeletal muscle. Firstly, mitochondrial function and metabolism in resting skeletal muscle were examined for 7 LTx recipients, 3-24 months post operation. Secondly, exercise performance for patients with lung transplantation was investigated. Resistance training is an effective exercise mode for improving muscle bulk and strength in sports and medical rehabilitation. Recently, resistance t

The biomechanical role of the sacroiliac joint during gait is to absorb both ground reaction forces and shear forces during movement. Analysing the gait of patients with sacroiliac joint dysfunction is vital if there is to be an increase in the understanding of its role in low back and pelvic pain and related dysfunctions. The diagnoses of somatic dysfunction utilised by the osteopathic profession have not been validated by experimental data, and the aim of the study was to investigate whether ground reaction forces during gait might be associated with these dysfunctions.

Abstract:

Mitochondrial adaptation in skeletal muscle is promoted by a diverse array of stimuli, and changes in mitochondrial plasticity have been noted as a result of a many exercise modalities. High-intensity interval training is one such modality that promotes mitochondrial adaptation in response to repeated short-duration bouts of intense effort. Another result of intense muscular effort is a decrease in muscle pH, resulting in intracellular acidosis. The effect of this acidosis on oxygen consumption in muscle has received attention previously, with mixed findings. An aspect of skeletal muscle mitoc

Abstract:

Team-sport competition is intermittent in nature, with large amounts of low to moderate intensity activity interspersed with periods of repeated high intensity efforts. As well as the locomotor distance, there are game involvements that require excellent strength and power with a high metabolic cost. Therefore, team-sport athletes need a unique mixture of strength, power, speed, endurance, and intermittent running ability. Altitude training can improve endurance and repeat sprint performance. There is also the potential to increase strength and hypertrophy when resistance training is per

Abstract:

The regulation of glucose uptake and mass in skeletal muscle are essential for the maintenance of functional capacity, general health, and quality of life. Skeletal muscle can be categorised into two major types, glycolytic and oxidative muscles. The regulation of muscle glucose uptake varies between the two muscle types, dependent on specific conditions, such as whether or not insulin is present, and whether the muscle is at rest or following exercise. Furthermore, muscle atrophy in response to disuse, disease or aging also occurs in a muscle type-specific manner. However, the exact mechanism
