Abstract
Strong wind, low temperature, intense current and poor visibility under water are the most common stress inducing factors in individuals practising water sports. Stress is a state of agitation, which can be caused both by external and internal factors. Its objective is to mobilise one’s physical and psychological capabilities, thus it is a favourable reaction especially in crisis situations when such full mobilisation enables one to cope. Psychological stress is usually evoked by the occurrence of an atypical situation, exceeding one’s handling capacity. It can be induced by seeing real or imagined danger in the surroundings, as well as by external pressure related to a task interpreted as too difficult or exceeding one’s capabilities. Internal pressure appears when a person feels insecure in a given situation, when they cannot solve a problem or they feel discomfort due to their inability to meet the expectations of others, for instance, to perform a particular dive, or because of the money spent on this purpose or the invested time. Physical stress is usually an organism’s response to the environmental impacts. This article presents and discusses factors which have an effect on stress intensification, as well as providing a characterisation of selected psychological and medical theories of stress.
