In the spectrum of underwater activity in South Africa, research into underwater physiological aspects of diving safety occupies a low priority, being made secondary to prevention, treatment and training. The aim of the underwater scientist is, among others, to discover procedures that would enhance diving safety for both the sportsman, who often dives pnoeically, and the industrial diver, who dives mostly with selfcontained underwater breathing apparatus (scuba).
The objective is to provide a recommendation for outpatient treatment of acute symptomatic pulmonary histoplasmosis in cavers, that is safe and effective. Published literature on the management of acute symptomatic pulmonary histoplasmosis is reviewed. Clinical experience involving 50 cases with acute symptomatic pulmonary histoplasmosis is presented, and provides the basis for the recommendations for treatment.
Tennis elbow was first descriptionbed in 1873. It is interesting to note that this was the same year that lawn tennis was invented. Medically, the correct terminology is that of epicondylitis of the elbow. This is a very common injury seen in tennis players. It has been estimated that almost half of all tennis players over the age of 30years suffer from tennis elbow at some stage in their playing career.
The objective is to investigate areas of concern, and subsequent anxiety levels, of canoeists before the 1997 Dusi Canoe Marathon. Subjects are the two hundred and fifty-one consecutive entrants at the Dusi registration in Pietermaritzburg and Durban.
The electromagnetic radiation which reaches the earth from the sun extends from 290 to 4,000 nm, from the ultrashort invisible radiation through the visible spectrum to the infra-red spectrum. Sunburn is the unpleasant result of exposure to sunlight of 290 to 320 nm in the ultraviolet spectrum and varies from mild erythema to a fiery redness with oedema and blistering.
The purpose of the study was to monitor the mood states of the members of the medical team in an international sports setting (the Olympic Games), with particular reference to indications of burnout. In addition a mood profile was ascertained for an individual athlete participating in the Games.
Rugby can be regarded as a collision sport and injuries, as in other collision sports such as rugby league, grid-iron football, Australian rules football and soccer, are unfortunately part of the game.
In distance running, the struggle is not man against woman. And not even man against man. It is a personal battle. At her sport, Isavel, a world-class female athlete will always beat me and 99% of the other males on this planet.
The anterior cruciate ligament (ACL) is a primary knee joint stabiliser preventing anterior tibial translation. Disruption of the ACL leads to an increased incidence of episodes of giving way of the affected limb, knee joint instability, and chronic quadriceps muscle atrophy. It was previously thought that this quadriceps muscle atrophy was a consequence of a relative disuse atrophy caused by post-injury immobilisation. However, recent work has shown that changes in activity in the muscles around the knee joint are regulated by neural mechanisms which are altered after disruption of the ACL.
Extensive research exists on the skating sports of ice hockey and speed skating. This research shows that these sports are physically demanding and stressful activities. Figure skating and ice-dance skating are Winter Olympic sports, yet little is known about the level of physiological stress in these sports.
