The results were based upon subjective and objective clinical findings, as well as effect on running performance.

Dissertation submitted in partial compliance with the requirements for a Masters Degree in Technology, in the Department of Chiropractic at the Durban University of Technology, 2008 / Introduction: One of the most important responsibilities of a rugby coach towards players is that of injury prevention and advice. Often these responsibilities fall solely on the coach, but sometimes he has the benefit of sports medical personnel at his service. Therefore in order for the coach to best service this sport and industry, his/her knowledge and perception of Chiropractic and other sports medical personnel is critical. Objective: To establish an understanding of Durban rugby coaches’ perceptions and knowledge of Chiropractic to formulate initiatives aimed at bridging gaps and building co-operation between coaches and various medical personnel that they have at their disposal. Methods: A survey was distributed to 149 rugby coaches within 23 high schools and 67 rugby coaches within 24 rugby clubs, resulting in a total of 219 rugby coaches in the greater Durban area received a questionnaire for completion and return. Results: Of the 85 coaches that participated (38.8% response rate), the majority were White (95%), male (99%), with a mean age of 37.36 years and coached at the amateur level (65.1%). School coaches dominated the participants with 67.1% with 61 (71.8%) having obtained a rugby coaching qualification and 26 (30.6%) having another professional sport, fitness or medical qualification besides that of rugby coaching. Most (94.9%) participants referred players to a health professional for examination and / or treatment. This included Physiotherapists, 80% of the time, GPs 70.6% of the time and Chiropractors, 60% of the time. Twenty-nine (34.1%) had a Chiropractor on their medical management team and 28 (96.6%) said it was a positive experience. Of those who did not have a Chiropractor on the team, 82.4% said they would consider it in the future. Over half (65.5%) had personally been treated by a Chiropractor. The 3 most frequent conditions associated with Chiropractic included: Disc herniation (42.6%), low back pain (36.1%) and whiplash (32.8%). Notwithstanding this outcome, the level of knowledge was low with the mean knowledge score (an aggregate knowledge score derived statistically from all questions relating to the knowledge of Chiropractic) of the group was 55.8% (SD 21.9%), even though the range varied from 0 to 96%. Although the coaches’ knowledge of Chiropractic was low, most participants (76.2%) had a favourable view of the Chiropractic profession. Furthermore the coaches perception of Chiropractic related significantly to their knowledge (p = 0.037). In addition the higher their knowledge scores the more positive their view. Conclusion: This study established what knowledge base is available that could promote rugby coaches greater understanding of the Chiropractic profession and related medical personnel. There was a positive association between increased knowledge and a better perception of Chiropractic, suggesting that if knowledge were improved, then perception and attitude towards Chiropractic and related medical personnel would further improve. This increased awareness may improve knowledge, understanding, communication and utilization with the Chiropractic profession and related medical personnel and ultimately these professions within rugby may gain a greater level of acceptance.

Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic at Durban University of Technology, 2008. / Objectives: To investigate the International Sports Federations’ (IFS) perception and utilization of chiropractors and other sports medical personnel, and to compare results between the executive committees and medical commissions within federations. Methods: A specially designed, quantitative questionnaire was used to collect data from the 65 federations belonging to the General Assembly of International Federations of Sport (GAIFS). The questionnaire distribution took place via e-mail, with the secretary of each federation being requested to forward a copy of the questionnaire to a member of the federation’s executive committee and medical commission respectively. Follow-up telephone calls were also made to further encourage a response from participants. After an 8-week period, returned questionnaires were collected and data was analyzed. Results: From the results obtained (30% response rate), it would seem that perceptions vary greatly. This is most evident when one compares the perceptions of the medical commission members to those of the executive committee members. The medical commission on a whole, appears to favour the more traditional medical professions, while the executive committee seems to be more holistic in their approach to treatment options. In terms of current utilization, chiropractors are currently represented on 16% of medical teams, although chiropractors are able, within their scope of practice, to provide 70% of the federations’ most requested techniques / modalities for competitions. There appears to be little / no criteria governing the selection of medical personnel, however most of the federations agreed that a chiropractor with a post-graduate diploma in sports injuries, would be seen in a more favourable light for selection. Conclusions: The perceptions and utilization of chiropractors and other sports medical personnel varies greatly between federations, which may be due to a number of factors related to the formulation of perception itself. In addition, there appears to be a discrepancy between the opinions of the executive committees and medical commission of the participating federations.

Background: The homeopathic preparation, Traumeel S, has been used as a valuable alternative to conventional non-steroidal anti-inflammatory drugs (NSAIDS) for over 30 years. This antihomotoxic, anti-phlogistic drug has been widely used by sportsmen and women in the treatment of lesions and inflammatory processes which result from exercise-induced skeletal muscle microtrauma. Although numerous randomised, double-blind placebo-controlled trials have confirmed the efficacy of Traumeel S as an anti-inflammatory agent, there are few in vivo studies which have specifically investigated the mechanism by which Traumeel S is effective in reducing inflammatory response to exercise-induced muscle cell damage. Aim: To establish whether the administration of Traumeel S during the five days before participation and three days following participation, significantly attenuates the systemic markers of the inflammatory response, following a 90-minute downhill running trial. Method: Twenty-four healthy athletes (14 men and 10 women), aged 20-50 years, were recruited for this study. Following baseline laboratory testing and familiarisation with the treadmill as well as a field test, subjects were matched according to gender, BMI, training age, training status, peak performance and foot strike patterns and randomised into Traumeel (TRS) and Control (PLAC) groups in a placebo-controlled, double-blind design. One Traumeel S or Placebo tablet was ingested three times per day for five days prior to and three days following a 90-minute exercise trial on a downhill (-6% gradient) at 75% V02 max- Blood samples were collected prior to the 90-minute trial (PRE), immediately after the trial (IPE) and 24 hours (24 PE), 48 hours (48 PE) and 72 hours (72 PE) following the trial. Each subject was also requested to complete a training record prior to the trial and keep a record of the daily symptoms of delayed onset muscle soreness (DOMS) both at rest (general pain) and during walking (daily living). Full blood counts (FBC), serum creatine kinase (CK), lactate dehydrogenase (LDH) and Cortisol concentrations were measured using standard haematological laboratory procedures and serum C-Reactive Protein (CRP) was determined by immunoturbidimetric assay. Sandwich ELISA's were used to determine myeloperoxidase (MPO) and plasma interleukin-6 (IL-6) concentrations. All results obtained were adjusted for changes in plasma volume as calculated from the red blood cell indices. Results: Mean ± SD characteristics of the gender-matched subjects in the experimental (TRS) and placebo-control (PLAC) groups did not differ significantly in terms of BMI, age, % body fat, FVC, FEVi, training age and status, foot strike pattern or peak running performance, maximal Heart Rate, VE, V02peak> RER, RPE during the maximal exercise test (p > 0.05). This indicated that the randomised pairs were well matched. The 90-minute downhill running protocol resulted in significant elevations in total circulating white blood cell count (WBC), neutrophil, CK, LDH, Cortisol, CPR, MPO and IL-6 concentrations (p < 0.001). When comparing the TRS and PLAC groups, mean ± SD total and differential WBC count, neutrophil count, CK, LDH, Cortisol, CPR, MPO and IL-6 concentrations did not differ (p > 0.05) over the 5 time points. At 24 PE, MPO concentrations were significantly higher in the TRS group than in the PLAC group (p = 0.03). The lower mean ± SD post-trial DOMS scores reported by the TRS group were not significantly different from those reported by the PLAC group (p > 0.05). Conclusion: Although the findings of this study did not identify differences in circulating CK, LDH, Cortisol, CPR and IL-6 concentrations between the TRS and PLAC groups, the elevated MPO concentration at 24 PE did provide preliminary novel evidence of enhanced activation of neutrophil oxidative burst activity following exercise-induced muscle damage which is hypothesized to accelerate the recovery process. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, 2008.

Cross-sectional studies have shown that well trained endurance athletes frequently have a lower peripheral and central chemoreceptor response (pRc and cRc) and a lower minute ventilation (Ve) during exercise compared to untrained individuals. Some recent prospective studies support these observations. We speculated that the reductions in chemoreceptor response and Ve may be the specific result of the high rates of ventilation occurring during endurance training. To test this idea, subjects performed voluntary eucapnic hyperpnea to simulate exercise hyperpnea while avoiding the metabolic consequences of physical exercise. We therefore examined the effects of respiratory muscle training (RMT: 20x30min sessions of voluntary eucapnic hyperpnea) on the pRc, cR, cycling performance, and Ve. Twenty endurance trained cyclists were randomized into RMT or control-groups. To indicate cRc both the hypercapnic ventilatory response at rest (HCVRr) and during light exercise (HCVRex) were measured in a background of 50% O2. The pRc was assessed by measuring the ventilatory response to a modified Dejours O2 test (4-6 trials of 10-12 breaths of 100% O2) during light exercise. Endurance performance and Ve were measured during a fixed-rate cycling endurance test, performed at 85% of the maximal workload until exhaustion. The RMT-group's cycling endurance improved significantly compared to controls (+3.26±4.98min versus -1.46±3.67min. p=0.027) but Ve was unchanged at all times analyzed. The pRc was significantly reduced in the RMT-group but unchanged in controls (-5.8±6.0% versus +O.1±4.6%, p=O.032). The cRc, both at rest and during exercise, was not significantly altered following RMT in either group. However, the X-intercept of HCVRex exhibited a significant shift to the left (-5.83±10.68mmHg, +O.38±2.48mmHg, p=O.047, RMT-group and controls respectively). The importance of this leftward shift and the reduced pRc, though statistically significant, is unclear because there were no significant changes in Ve during any test nor were there correlations between Ve or performance or the altered chemoreceptor responses. We conclude that exercise hyperpnea, as simulated by RMT in this study, is accompanied by a reduction in pRc and a leftward shift in the HCVRex, and improves cycling endurance; however, the altered chemoreceptor responses had little impact on Ve suggesting that their role in the control of ventilation during exercise is minor.

This autoethnographic study investigates the emotional and social dimensions of a coaching relationship from the athlete�s perspective. Autoethnography is an approach that draws on highly personalised biographical accounts in which authors tell stories about their lived experiences (Ellis & Bochner, 2000; Richardson, 2000) in order to place the "self within a social context" (Reed-Danahay, 1997, p. 9). Consequently, through the analysis of my memories and ethnographic notes, I analyse my experiences as an Olympic marathon runner and, in particular, the challenges I faced with my coach. In the process of investigating the emotional and social dimensions of the coaching process (which I have divided into three phases), I focus specifically on the creation of (1) my 'athletic identity', (2) the power relationship that developed between my coach and myself and, (3) my early retirement from running. In order to make sense of my experiences, I draw upon theories of identity (e.g. Bradley, 1996), Foucauldian concepts on 'power' (e.g. Foucault, 1980), and the literature addressing 'premature retirement' (e.g. Sparkes 1996; 2000). Finally, a conclusion summarises the main points made in addition to outlining their implications for further coaching research and practice.
