The readmission of South Africa to international sport has given many in the sports medicine community, the opportunity to work and travel with both national and provincial teams representing a very wide variety of sporting disciplines. When those sports enjoy a high profile with the South African public, there will be heightened press interest in whatever happens either on or off die field, including the medical problems that die team encounter.
The body may fail to thermoregulate because either the rate of heat production exceeds the rate of heat loss leading to heat retention or because the rate of heat loss exceeds that of heat production leading to hypothermia. The greater interest in the exercise sciences and in clinical sports medicine has been in the disorders considered to be due to heat retention. Only more recently has it been realised that hypothermia, first recognised in Channel swimmers and mountain climbers and hikers, can also occur in marathon and ultramarathon runners competing in cold, wet and windy conditions.
There are two distinct forms of underwater activity which need to be differentiated, namely breath-holding diving and SCUBA (self-contained breathing apparatus) diving. Each of these share the challenge of the raised environmental pressure, but the physiological responses and their possible sequelae may differ substantially.
The objectives of this paper is to descriptionbe the general anthropometric characteristics, and trunk and upper limb patterns of flexibility, and forearm muscle strength of male competitive sport rock climbers in a descriptionptive survey.
