    Jet lag and environmental conditions that may influence exercise performance during the 2010 FIFA World Cup in South Africa
    (2010) Schwellnus, Martin; Derman, Elton
    The 2010 FIFA World Cup will be held in South Africa in June/July 2010. This is the largest international sports event ever to be held in this country. At this time 32 international football teams, with their management and supporters, will travel to South Africa. These players and visitors will be exposed to changes in time zones (those travelling from continents in the East and West) as well as different environmental conditions. In particular, for the players, the achievement of peak sporting performance during this event is most important. It is well established that, in order to achieve peak exercise performance, many variables need to be optimised. These variables include physical and mental training, rest, nutrition, team dynamics and tactics. However, adjustments to differences in time zones as well as environmental factors on and around the playing field can also have a significant impact on exercise performance. In this review, the potential effects of “jet lag”, as well as several important environmental conditions, on exercise performance will be discussed. The climatic, atmospheric and weather conditions that are likely to be prevalent in each of the South African host cities at the time of the 2010 FIFA World Cup will be reviewed. Finally, practical recommendations to deal with the effects of jet lag, as well as guidelines to optimise performance under different environmental conditions that are expected during the 2010 FIFA World Cup, will be provided.

    Pain management in sports medicine: Use and abuse of anti-inflammatory and other agents
    (2010) Derman, Elton; Schwellnus, Martin
    Over the last two decades, the health benefits associated with increased physical activity have been established.1 However, with increased participation in physical activity comes a subsequent increase in sports and exercise related injury. It is estimated that there are over 4.2 million visits to the emergency rooms for sport and exercise related acute injury in the United States alone, and at least that number of visits due to chronic sport and exercise related injury.2,3 This article will focus on the use of pharmacological agents in the acute management of these injuries.

    Psychological factors and physical outcomes in patients with chronic diseases of lifestyle
    (2016) Skowno, Philippa; Derman, Elton; Stein, Dan J; Draper, Catherine E
    INTRODUCTION: Chronic diseases of lifestyle (CDL) are a major cause of global morbidity and mortality. Although CDL are largely preventable and treatable through adopting and maintaining healthy lifestyle behaviours, CDL rehabilitation programmes remain an underutilised resource. Behaviour modification is thus complex, and requires a collaborative approach between psychologists and medical clinicians involved in the management of CDL. This thesis examined the role of psychological factors in the management of patients with CDL who participated in a comprehensive lifestyle intervention (CLI) programme. METHODS: An explanatory mixed methods design was used to describe the CLI experience. These included an initial clinical audit of 308 patients commencing and completing a twelve week CLI programme to test associations of psychological, demographic, medical and diagnostic factors with physical outcomes. Two qualitative studies were subsequently conducted to further understand patient experiences of CDL and CLI programmes. The first involved interviews of 14 patients at programme commencement and completion. The second consisted of a case study of a patient participating in the programme using human centred design principles as well as ethnography.
