- ItemOpen AccessThe application of clinical gait analysis to running injuries(2005) Arendse, Regan Emile; Schwellnus, Martin; Gibson, Alan St ClairClinical evaluation of the injured runner requires identification and correction of the multiple factors commonly implicated in running injury. Effective management of running injuries requires that the concerned health professional identify all implicated factors. In this regard it is essential that the relationship between running style and injury he determined, because if there is an association between the gait analysis variables descriptive of running style and injury, these would be important in the management of the injured runner. The Gait Analysis Laboratory at the Sports Science institute of South Africa and the University of Cape Town with its three-dimensional Vicon 370 motion analysis system and Advanced Medical Technology industry® strain gauge force platform is appropriate for collecting data to study running style. These data include the movement patterns and estimated mechanical power and work required to effect the observed movement of the ankle and knee. The forces applied by the supporting surfaces on the runners were collected. The data captured with the Workstation® programme (Oxford Metric, Oxford, England), was processed with GaitLab® (Kiboho Publishers, Cape Town, South Africa), collated in Excel ® (Microsoft Corporation, Redmond, USA) and statistically analysed (StatSoft, Inc. (2000). STATISTICA for Windows [Computer program manual]. Tulsa, OK, USA). In this thesis a series of studies are presented with the aim of determining the relevance of running style to the assessment of the injured runner and the conventional treatment methods used to treat common running injuries.
- ItemOpen AccessThe effect of shoulder pain on the neuromuscular activity of the scapular stabilizing muscles(2005) Oliver, Delphine; Gibson, Alan St Clair; Gray, Janine; John, Lester; Taliep, SharhiddNeuromuscular activity of the scapular stabilizing muscles in subjects with and and without chronic shoulder impingement syndrome. To examine differences in neuromuscular activity of the scapular stabilizing muscles in subjects with and without chronic shoulder impingement syndrome during an abduction movement of the shoulder.
- ItemOpen AccessEffects of antecedent exposures and physiological perturbations on perceived exertion, muscle activation and performance during open and closed loop exercise(2006) West, Sacha Jane; Gibson, Alan St ClairThe aim of this thesis was to examine the effect of various antecedent exposures and physiological pertubations on the relationship between the perceptual (perceived exertion), the physiological (metabolic milieu), and the performance (overall exercise performance) during both open and closed loop exercise at either a self-placed or constant workload.
- ItemOpen AccessEndurance performance : the integrative physiology of resisting fatigue(2004) Harley, Yolande Xanthe Rocille; Gibson, Alan St Clair; Collins, MalcolmIncludes bibliographical references.
- ItemOpen AccessExercise induced neuroprotection in spontaneuosly running rats(2007) Mabandla, Musa Vuyisile; Gibson, Alan St Clair; Russell, Vivienue AWe investigated the effects of voluntary exercise on neuroprotection after unilateral lesions with 6-hydroxydopamine. Rats were divided into runners (had access to running wheel) and non-runners (their running wheels were immobilised). Two weeks after injection of the neurotoxin, the rats were injected with apomorphine and the number of ipsilateral and contralateral rotations was counted with contralateral rotations of greater than 150 considered to represent striatal dopamine neuron destruction of 70% or above.
- ItemOpen AccessIn every given moment : the affective, cognitive and physiological concomitants of mindfulness(2005) Ives-Deliperi, Victoria; Louw, Johann; Gibson, Alan St ClairAn impressive collection of research has shown that mindfulness - described as a heightened awareness of the present moment - nurtures inner resources for reducing stress, and improving well-being. The aim of this study was to further validate, and add to these findings by illustrating the relationship between mindfulness and affect, cognition and physiological reactivity to stress.
- ItemOpen AccessThe investigation of phase synchronization in the cortex during a fatiguing muscle contraction using EEG(2005) Bosanquet, Devin Roy; Gibson, Alan St Clair; Sreenivasan, RIncludes bibliographical references (leaves 140-157).
- ItemOpen AccessNeuromuscular control and physical performance following anterior cruciate ligament reconstruction using a semitendinosus(2006) De Villiers, Elsje; Gray, Janine; Gibson, Alan St ClairIncludes bibliographical references.
