The purpose of the study was to explore the psychosocial factors involved in the susceptibility, experience and rehabilitation of injuries sustained in long-distance running in order to develop a biopsychosocial theoretical model that will help explain the experience of injury and the successful rehabilitation thereof in long-distance running. The study was approached from a biopsychosocial theoretical perspective. A mixed methods research design with the purpose of expansion and using 15 case studies was employed. Purposive sampling with a snowballing effect was used to select the 15 long-distance runners who were injured or had recently recovered from injury. Semi-structured interviews were conducted with each of the participants. Furthermore, each participant completed the Myers-Briggs Type Indicator. An examination of the participants’ experiences of injury reveals that injury has an effect on and is affected by the following factors: running history and training program; perceived benefits and disadvantages of running; personal understanding of injury; personality factors; psychological responses to injury; perceived causes of injury; approach to rehabilitation; and coping mechanisms. Furthermore, there is an inherent interplay of biological or physical, psychological and social processes involved in the experience of injuries sustained in long-distance running. Based on the findings of the study, the biopsychosocial model of long-distance running injuries is proposed. Although the model emanates from the experiences of the 15 participants in the study, it may be applied to long-distance runners in general. A long-distance runner’s experience of running is the core of the model. The model depicts how each of the factors noted previously has an effect on and is affected by injury; thus, showing the integral relationship between injury and each of the factors. Furthermore, the biopsychosocial nature of the model is also portrayed in the model. Cognizance is also taken that all long-distance runners are individuals and may respond to injury in a unique manner. / Thesis (PhD)--University of Pretoria, 2012. / Psychology / unrestricted

Text in English / Regular exercise has significant physical and psychological health benefits yet, paradoxically, may also have harmful effects. The purpose of this study was to investigate the physical and psychological health risks of distance running, a popular participation sport in South Africa. Structural equation modelling was employed to examine the personality and motivational antecedents of running addiction and its influence, in turn, on self-reported overuse injuries and upper respiratory tract infections in 220 athletic club members. The predictors and physical health effects of customary training load were also assessed. It was found that perfectionistic concerns, Type A behaviour pattern, and task goal orientation had a direct, positive impact on running addiction, which predicted higher running injury scores. In contrast, training workload (Volume × Intensity) was inversely related to injury risk. Neither running addiction nor any training load variables influenced infectious illness susceptibility. The findings of this study indicate that maladaptive perfectionism, Type A behaviour, and achievement goal orientation may be risk factors for running addiction, which may, in turn, contribute to increased injury incidence in South African distance runners. Conversely, heavier training loads may be protective against injury occurrences in this population. The results of this research may help to enhance current understanding of the possible health hazards of distance running. This knowledge may have practical implications for the health and well-being of runners of diverse levels of ability and experience. / Psychology / D.Litt. et Phil. (Psychology)
