WHAT L.C de Villiers is the official sports-grounds of the University of Pretoria and hosts the High Performance Centre (HPC). This world class sports clinic was designed as a rugby training facility, but is currently used as a training and accommodation centre catering for various sport codes. The HPC has enjoyed great success; to such an extent that the facility is overcrowded and expansion plans are in the pipeline. WHY A twin HPC facility is planned on the Groenkloof campus. This campus has developed sportsfields, existing infrastructure,ample space for development, cultural significance and forms part of the southern gateway of Pretoria. HOW This study investigates how a HPC integrates with Groenkloof campus. Furthermore, stormwater management will be investigated. Lastly a material selection referenced from relevant history will be put together for detail design. / Dissertation (ML(Prof))--University of Pretoria, 2009. / Architecture / unrestricted

Background: Injuries are common in professional football, especially during matches, and they cause suffering for players, in both the short and the long term. It is therefore important to try to prevent these injuries. One of the most important steps in injury prevention is to fully understand the different risk factors that contribute to these injuries. Aim: The aim of this thesis was therefore to investigate several match-related factors that have been suggested to be important for the risk of sustaining injuries during professional football matches. Methods: The thesis consists of four papers, and all analyses are based on data gathered during a large-scale prospective cohort study that has been running since 2001: the UEFA Elite Club Injury Study. Medical teams from 61 clubs have been involved in this study, and they have prospectively gathered data about football exposure and injuries for their first team players. Associations between the following factors and injuries have been analysed: • Match characteristics in terms of match venue, match result, and competition • Match congestion, both short and long term, and at team and individual player level • Number of completed training sessions between return to sport after an injury and the first match exposure Results: All match characteristics studied were shown to be associated with injury rates, with higher injury rates during home matches compared with away matches, in matches that were lost or drawn compared with matches won, and in domestic league and Champions League matches compared with Europa League and other cup matches. It was also shown that injury rates, muscle injury rates in particular, were higher if the recovery time between matches was short. This association between match congestion and injury rates was shown when match congestion was considered at both team and individual player level. Finally, the odds of injury during the first match exposure after a period of absence due to injury was found to be higher if players had completed few training sessions between return to sport and their first match. Conclusion: There are several match-related risk factors that contribute to the injury rate during professional football matches. A better understanding of these risk factors will help teams to make better estimations of the injury risks to which players are exposed in different situations (e.g. during periods of match congestion and when players return to sport after an injury). Knowledge about risk factors will also offer the possibility of reducing the number of injuries for football teams by addressing them with appropriate measures.

Stress in sport is complex and can lead to a number of undesirable consequences such as burnout, performance difficulties, interpersonal problems, and injury. Lazarus’s (1991, 1999) Cognitive-Motivational-Relational model holds that stress is best understood as a transactional relationship between a person and their environment. Stress is a process which is influenced by appraisals and coping. Appraisals are influenced by personal factors as well as environmental demands and the availability of external resources. Coping involves constantly changing cognitive and behavioral efforts to manage the perceived external and internal demands of a stressful situation (Lazarus & Folkman, 1984). The present study examined how appraisal processes mediated (or were possibly moderated by) the effects of social anxiety and perceptions of teammate social support on how high school female soccer players thought they would cope with a hypothetical interpersonal stressor. The study also examined simple relationships among variables. The participants were 181 female high school soccer players from Greater Vancouver. The athletes first completed two questionnaires designed to measure social anxiety (Interaction Anxiousness Scale; Leary, 1983a) and perceived social support from teammates (modified Social Provisions Scale; Weiss, 1974). After reading the scenario, the athletes indicated their appraisal of threat and challenge (Stress Appraisal Measure; Peacock & Wong, 1990) and how they thought they would cope (Coping Functions Questionnaire; Kowalski & Crocker, 2001). . The initial findings indicated that challenge appraisals were moderately correlated with both emotion-focused (r = .41) and problem-focused coping (r = .51), whereas threat had a weak association with avoidance coping (r = .19). Using mediation analysis, the results indicated that challenge fully mediated the relationship between social support and emotion-focused coping, and partially mediated the relationship between social support and problem-focused coping. Threat appraisals mediated the relationship between social anxiety and avoidance coping. Contrary to hypotheses, there was no evidence that social anxiety or threat were related to emotion-focused coping. There was also no support that person variables (social anxiety, social support) moderated the effects of appraisal on coping. The findings suggest that challenge appraisals and social support were key predictors of coping with interpersonal stress in this population. / Education, Faculty of / Kinesiology, School of / Graduate

The primary aim of this project was to both investigate injury epidemiology and create methods to potentially reduce injuries within elite ice hockey athletes. Chapter Four assessed the injury problem within ice hockey by retrospectively collecting data from two National Collegiate Athletic Association (NCAA) division III teams across a four year period investigating the prevalence, location, severity and type of injuries sustained. Findings showed that contact injuries were more prevalent (58%) than non-contact injuries (42%), with the knee (15%), shoulder (12%) and hip (13%) being the most frequently injured locations when both contact and non-contact injuries were combined. When investigating only non- contact injuries the hip complex (hip, groin and thigh) (50%) was by far the most injured location with similar frequencies, in terms of injury severity, observed. Chapter Five analysed intrinsic risk factors of the ice hockey athlete by investigating differences of hip range of motion (ROM), strength and functional tests between ice hockey athletes, soccer athletes and control participants. Results demonstrated that ice hockey athletes had significantly weaker hip adduction (p = 0.023) and flexion in sitting (p = 0.001) strength compared to soccer athletes and less external rotation strength compared to control participants (p = 0.010). Ice hockey athletes also displayed greater strength than control participants in flexion in sitting (p = 0.005). Ice hockey athletes exhibited greater ROM in abduction (p = 0.001) than control participants and greater adduction than both soccer athletes (p = 0.003) and control participants (p = 0.004). Ice hockey athletes exhibited less hip flexion in lying (p = 0.001) and external rotation (p < 0.001) when compared to control participants. Ice hockey athletes also presented with an increased number of positive flexion, abduction and external rotation (FABER) tests compared to both soccer athletes and control participants. Chapter Six investigated the effectiveness of the newly created hip screen by comparing ice hockey athletes with and without a previous non-contact hip injury and their performance during the hip screen. Findings demonstrated that athletes who had no previous hip injury had greater internal (p = 0.004) and external rotation ROM (p = 0.022) on the dominant (Dom) limb and greater flexion in sitting (p = 0.031) and internal rotation ROM (p = 0.050) on the non-dominant (Ndom) limb. Although non-significant, previously injured athletes also displayed less ROM in all hip movements compared to previously uninjured athletes. Similar trends were found in strength measures with previously uninjured athletes showing significantly stronger abduction (p = 0.012) on the Dom limb and flexion in lying on both the Dom (p = 0.008) and Ndom limb (p < 0.001). Previously injured athletes displayed more positive FABER (Dom; 13% vs. 0%, Ndom; 13% vs. 5%), Trendelenburg (Dom; 75% vs. 58%, Ndom; 50% vs. 5%) and Ober’s (Dom; 13% vs. 5%, Ndom; 75% vs. 68%) tests with higher scores on the overall screen than uninjured athletes. Chapter Seven investigated the intra and inter-tester reliability of the hip screen finding that intra-class correlation coefficients (ICC) of intra-tester reliability of the ROM (0.49), strength (0.80) and overall screen (0.76) was moderate to near perfect. Inter-tester reliability again showed very large ICCs for ROM (0.71), strength (0.77) and overall screen scores (0.81). The minimum criterion change (MCC) (3.78 points) was also found to be small for the screen score change needed to be viewed as clinically worthwhile. These findings demonstrate that the screening procedure developed is useful, reliable and repeatable when assessing the ice hockey athlete’s hip. Chapter Eight demonstrated that all participants regardless of group improved their ROM and strength measures following the intervention period. However, it was demonstrated that the ice hockey intervention (IHI) group saw a decrease in the amount of positive FABER tests following the intervention compared to ice hockey control (IHC) and intervention control (IC) group (IHI: pre 15 vs. post 6; IHC: pre 15 vs. post 14; IC: pre 10 vs. post 9). It was also demonstrated that the IHI group improved above the MCC value presented within Chapter Seven with regards to the overall hip injury screen score (pre 48 vs. post 52) indicating that ice hockey athletes who participated in the intervention programme may be at a decreased risk of sustaining a non-contact hip injury due to the intervention exercises targeting weaknesses highlighted in the hip injury screen. In summary, the current project achieved the stated aims by demonstrating that the hip complex was the most common location for injuries of a non-contact nature and the creation of a reliable and repeatable hip injury screen that allows clinicians to potentially highlight athletes considered as ‘at risk’. To complete the injury prevention sequence, future work would be necessary to track athletes who scored low on the hip injury screen over time either following the intervention or as a control to assess if they were more or less likely to sustain a non-contact hip injury. Future work should also continue to optimise the intervention strategy to further develop and enhance its effectiveness in the prevention of non-contact hip injuries. This could be achieved either through a longer protocol that is incorporated into routine training or individualisation of the programme and as such provide a valuable tool for clinicians and medical teams wishing to reduce the risk of ice hockey athletes sustaining a non-contact hip injury.

The Munich Air Disaster claimed the lives of 23 people in a plane crash in Munich in 1958. It is a significant event within modern England’s cultural history as a number of Manchester United footballers, known as the Busby Babes were amongst the dead. The players who died have continued to be extensively commemorated, especially Duncan Edwards. This research considers the commemorative activity associated with Edwards since his death and was initiated when the researcher pondered the extensive commemorative activity by strangers that she encountered at the family grave of her cousin Edwards. The commemoration of the Disaster and of Edwards has been persistent and various with new acts of commemoration continuing conspicuously even after fifty years since the event. Such unique activity particularly demonstrated at Edwards’ grave was considered worthy of further investigation to ascertain why such activity was occurring at such a volume. Although general historical and biographical accounts of the Disaster and Edwards are apparent, specific research concerning the commemoration of the event was not evident. The researcher set out to identify who the commemorators were, why they were undertaking dedicatory acts and what those acts manifest as. At Edwards’ grave the offerings left upon it were regularly documented from 2010-2014 and analysed. Interviews with identified significant commemorators were undertaken including Edwards’ family members and fans. A comprehensive literature review was undertaken and relevant online sources and data were also examined in order to inform a distinct social and cultural analysis of the event within the context of its commemoration. The study focussed upon the researcher’s connection to the subject, commemorators, memorials, commemorative objects and sites. Although there was a distinct personal element to the research, the data collected was analysed in the wider context of commemoration, the perception of heroes and attitudes towards the dead, death and dying. This research specifically considers the commemoration of Disaster victim Duncan Edwards as a local sporting hero. The unique contribution to the knowledge and understanding of this research topic is principally through the generation and interrogation of new research data, created from fieldwork undertaken at Edwards’ grave and from interviews with significant commemorators. The interview-generated research data from certain Edwards’ family members was only possible to attain because of the researcher’s particular ancestral link to the interviewees.
