Swimming Efficiency

Cold water swimming (winter or ice swimming) has a long tradition in northern countries. Until a few years ago, ice swimming was practiced by very few extreme athletes. For some years now, ice swimming has been held as competitions in ice-cold water (colder than 5 °C). The aim of this overview is to present the current status of benefits and risks for swimming in cold water. When cold water swimming is practiced by experienced people with good health in a regular, graded and adjusted mode, it appears to bring health benefits. However, there is a risk of death in unfamiliar people, either due to the initial neurogenic cold shock response or due to a progressive decrease in swimming efficiency or hypothermia.

Shock Response

AbstractThe protection provided by three clothing assemblies against the cold shock response was investigated. Nine healthy male volunteers each undertook three two minute head-out immersions into stirred water at 10°C. The subjects wore a different clothing assembly for each immersion, these were: (a)Swimming trunks only;(b)Conventional clothing (equivalent to RN No 8s);(c)Conventional clothing plus windproof/showerproof clothing (RN foul-weather clothing Mk III).The cardiac, ventilatory and thermal responses of the subjects were examined before and during the immersions.No significant differences were found between the magnitude of the responses recorded on immersion when conventional clothing or foul-weather clothing were worn. Mean skin temperature was lower (P<0.05) and respiratory frequency and minute ventilation were higher (P<0.05) on immersion in swimming trunks compared to the other two conditions.It is concluded that when policies for the use of immersion protective clothing are being formulated, consideration should be given to all of the potentially hazardous responses associated with cold water immersion.

Shock Response

ABSTRACTWhen subjected to rapid drops of temperature (cold shock), Neurospora responds with a dramatic, but temporary shift in its branching pattern. While the cold shock response has been described morphologically, it has yet to be examined genetically. This project aims to begin the genetic characterization of the cold shock response and the associated acclimatization to cold environments. We report here the results of a screen of mutants from the Neurospora knockout library for alterations in their morphological response to cold shock and thus, their ability to acclimatize to the cold. Three groups of knockouts were selected to be subject to this screen: genes previously suspected to be involved in hyphal development as well as knockouts resulting in morphological changes; transcription factors; and genes homologous to E. coli genes known to alter their expression in response to cold shock. Several strains were identified with altered responses. The genes impacted in these mutants are listed and discussed. A significant percentage (81%) of the knockouts of genes homologous to those previously identified in E. coli showed altered cold shock responses in Neurospora – suggesting that the response in these two organisms is largely shared in common.
