Epidemiological studies have reported that while undergoing intensive training or following long-duration competitive events athletes may have an increased susceptibility to infection. Various studies involving nutritional supplements have been done attempting to reduce either the immunosuppression following prolonged exercise and/or the subsequent risk of developing upper respiratory tract infections. It is the aim of this review to examine the evidence as to whether carbohydrate (CHO) feeding (supplementation or dietary) would provide a means of attenuating some of the immuno-suppression associated with prolonged exercise, and ultimately reduce the risk of upper respiratory tract infection.
The South African Institute for Drug-Free Sport was established in 1977 through an act of Parliament, with one of its key focus areas being 'The promotion of sport participation free from prohibited substances or methods intended to artificially enhance performance by implementing an anti-doping programme, incorporating public education, athlete testing and scientific research'. Arising from this key focus area, the institute surveyed the use or abuse and knowledge of ergogenic aids used by the South African team at the 1998 Commonwealth Games.
The 7th All Africa Games were held from 9 to 19 September 1999 in Johannesburg, South Africa. The objective of this study was to summarise the results of the doping control obtained in the laboratory. The Medical Commission of the Games asked the International Olympic Committee (IOC)-accredited laboratory in Bloemfontein to be responsible for the doping analyses during the Games.
To investigate the illness and infection rate following the 1996 Dusi Canoe Marathon, held under flood conditions, and to investigate the relationship between illness and water contact, canoeing experience and water pollution. Retrospective study by post-race questionnaire mailed to all participants asking for information on illness and infection during and after the race, water contact, canoeing experience and previous race-associated illness. Data relating to river pollution were supplied by Umgeni Water.
The object of this study is to determine whether the ingestion of stimulants (fencamfamine) enhances the accuracy and consistency of shot reproduction in cricket batting. Thirteen young elite or potentially elite cricket players were recruited for the study. An instrumented cricket bat measured the exact impact locations of 60 deliveries for each of the players in the randomised cross-over design under the experimental and control conditions. In addition, the coach subjectively rated each stroke as ï¿½goodï¿½ or ï¿½badï¿½.
An investigation was undertaken to ascertain the link between sensation seeking as a personality trait and the incidence of injury among rugby players. Four hundred questionnaires were given to the managers of 20 provincial high school rugby teams to be distributed among their players. In addition to demographic and injury information, the questionnaires included Zuckermanï¿½s Sensation Seeking Scale.
