Abstract:

Fatigue is a universal phenomenon with functional and perceptual consequences. The study of fatigue in the exercise sciences has historically focussed on factors that limit performance during exercise. More recent proposals have shifted the focus of this understanding to examine how intensity is regulated during exercise through the study of the pacing strategy, which has both physiological and practical consequences. The aim of this thesis was to investigate the biological basis of self-pacing and the optimum pacing strategy for endurance time-trial events. Study 1 assessed the reproducibilit

Abstract:

DNA methylation, an epigenetic modification which can regulate gene transcription independently from alterations to the nucleotide sequence, can be manipulated by lifestyle factors such as diet and exercise, hypothetically reversing aberrant DNA methylation associated with disease pathogenesis. The underlying mechanisms by which these changes occur are currently poorly characterised, however, in vitro data suggest that inflammatory mediators are involved. Furthermore, regular exercise appears to reduce inactivity-associated systemic inflammation, possibly by alterations to the methylome, there

Abstract:

Athletes and practitioners are continually looking for new strategies that could minimise the negative effects of exercise-induced muscle damage (EIMD) and hasten the recovery process. One strategy that has shown promise in recent years is the use of functional foods rich in phytonutrients. A functional food that has attracted a lot of attention recently, although primarily for its performance enhancing effects, is beetroot (Beta Vulgaris L.). In addition to displaying a range of physiological effects that may benefit athletic performance, beetroot also exhibits antioxidant (AOX) and anti-infl

This thesis comprises three main chapters-each comprising one relatively standalone paper.

In Chapter 1, I provide a formal development of alethic pluralism. Pluralism is the view that there are distinct truth properties associated with distinct domains of subject matter, where a truth property satisfies certain truth-characterizing principles. On behalf of pluralists, I propose an account of logic and semantics that shows how they ca

Introduction: A cluster of studies in the sport science literature employ interval training (alternating bouts of recovery and rest periods) interventions for the purpose of identifying optimal training intensities for endurance performance. There has been evidence to support the likelihood that among the most optimal training stimuli are two specific intensities: the velocity associated with the maximal rate of oxygen uptake (v 2max); and the intermediate velocity between v 2max and the velocity associated with the lactate threshold (vΔ50). It has not been shown to date, which of the two inte

Abstract:

Field hockey is a popular sport played worldwide. Due to the demands of the game, injuries are common, restricting participation. Injuries occur due to a single traumatic event or are due to repetitive loading. Injuries caused by repetitive loading, known as overuse injuries, have been linked to various measureable kinetic and kinematic variables. The magnitude, direction and distribution of the applied loads have all been identified as factors influencing the onset of an injury. Furthermore, footwear, surface and speed of locomotion have also been identified as factors which will influence in

Strength training using free weights is performed by athletes in many sports as a means of enhancing performance. However, there is a dearth of research investigating the acute impact of bouts of this form of strength training on muscle function, which closely mimics the athletes’ sport or event. High forces are produced during a rowing race and subsequently strength training forms an integral part of the overall training programme for rowers.

Athletes can approach competition positively, as a challenge, or negatively, as a threat. The theory of challenge and threat states in athletes (TCTSA) outlines that a challenge state, contrary to a threat state, is characterised by high levels of self-efficacy and perceived control, approach goals, positive emotions, a helpful interpretation of emotional state and a cardiovascular reactivity pattern of increased cardiac output and decreased total peripheral resistance.

Behaviour change interventions to increase children‘s physical activity have demonstrated limited impact which is not maintained over the longer-term.

Abstract:

Interleukin-6 (IL-6) is a pluripotent cytokine which has inflammatory properties. It is suggested to mediate a variety of processes including increased perception of fatigue during inflammatory states. In addition, prolonged exercise can cause a marked increase in circulating IL-6, and although there is a widely reported association between plasma IL-6 and fatigue in disease and inflammatory conditions, this relationship has remained relatively unexplored in healthy individuals during exercise.

Yet, on the other hand, this is bound up with continuous examples of little progress in work. For instance, while there are more opportunities for women across work than at any other point in the 20th Century, they continue to be segregated from men in a large number of jobs. Similar gendered patterns of progress are reflected in s

Abstract:

The central nervous system is highly sensitive to reductions in oxygen availability but the neurophysiological responses in healthy human lowlanders are not well understood. In severe hypoxia, whole-body exercise tolerance is impaired and neuromuscular fatigue, defined as any exercise-induced reduction in the ability of a muscle to generate force or power, reversible by rest, may be largely due to cerebral perturbations. The primary aim of this thesis was to determine the mechanisms of exercise-induced neuromuscular fatigue and the related neurophysiological responses to acute, chronic and int

Abstract:

The development of talent is a complex process mediated by a host of psychology, social, physical, and environmental variables. Unfortunately, the multiple processes involved in talent development (Gagne, 2004; Simonton, 2001) are frequently ignored by the systems and protocols employed in sport. Modem approaches to talent development are beginning to stress the initial possession, then subsequent development, of Psychological Characteristics of Developing Excellence (PCDEs; MacNamara, Button, & Collins, 2010) as the best way to realize latent potential. Accordingly, the aim of this thesis was

Abstract:

Prolonged moderate intensity cycle exercise is associated with a gradual and progressive reduction in gross efficiency (GE). It was speculated that this loss of GE might reflect a reduction in maximal muscle function and result in a parallel decline in aerobic performance. The effect of prolonged moderate intensity cycle exercise on maximal muscle function and anaerobic performance has not been clearly established. This thesis examined the impact of 1-2 h of cycling exercise at 60-65% maximal aerobic power in well-trained cyclists on subsequent changes in aerobic and anaerobic performance, GE

Abstract:

The current work is novel in that it investigated in vivo analysis of glucose metabolism during and following hypoxic exposure in type 2 diabetics. Using moderate levels of hypoxia, study one found that 60 min of resting hypoxic (Hy Rest) exposure reduced blood glucose concentrations in type 2 diabetics. Insulin sensitivity was also found to be significantly greater following hypoxic exposure when compared to the normoxic control. The second study showed that exercise under hypoxic (Hy Ex) conditions acutely reduced arterialised blood glucose concentrations. The total area under the curve for

This thesis investigates the England Visually Impaired Cricket Team, whose squad members comprise sixteen men aged 18-54, and their lived experiences' of playing visually impaired cricket. This is the first piece of research to examine elite visually impaired cricket and the first to explicitly analyse the social dynamics of any visually impaired sports team. Through an embodied theoretical approach, that accounts for the corporeal experience of impairment alongside the role of social institutions and discourse in the high performance culture of modern disability sport, this thesis establishes

Abstract:

Prefrontal cortex is frequently linked to dual-task gait performance; however, its precise role is unknown. The purpose of this thesis was to examine the role of prefrontal cortex in the control of dual-task gait. Using transcranial direct stimulation (tDCS) to alter prefrontal cortex activity, the influence of prefrontal cortex on dual-task gait performance and the corticospinal system was examined across four experiential studies using the guided activation framework of prefrontal cortex function (Miller and Cohen, 2001). The first study examined the role of cognitive task type and walking s
