PURPOSE This study aimed to investigate the effectiveness (speed of cooling and survival rates) of cold water immersion (CWI) in the treatment of patients with exertional heat stroke (EHS). Secondly, this study aimed to compare cooling rates on the basis of gender, age, and initial rectal temperature (Tr). METHODS Eighteen years of finish line medical tent patient records were obtained from t...

A child's heatstroke is an unexpected accident; however, we are able to prevent it analyzing the situation which occurred, and its cause. The large-scale research about a child's heatstroke had not been carried out to the past in Japan. According to Heatstroke STUDY, more than 90% of a child's heatstroke were aged 6 and over; furthermore, 70% of those children were doing sports. I expect that t...

The preoptic-anterior hypothalamus (POAH) controls body temperature, and thermoregulatory responses are impaired during hypercapnia. If increased CO(2) or its accompanying acidosis inhibits warm-sensitive POAH neurons, this could provide an explanation for thermoregulatory impairment during hypercapnia. To test this possibility, extracellular electrophysiological recordings determined the effec...

Does the action system contribute to action perception? Recent evidence suggests that actions are simulated while being observed. Given that the planning and simulating system are the same only when one observes one's own actions, it might be easier to predict the future outcomes of actions when one has carried them out oneself earlier on. In order to test this hypothesis, three experiments wer...

30 It is likely that the pathophysiology of exertional heat stroke (EHS) differs from passive heat stroke 31 (PHS), but this has been difficult to verify experimentally. C57Bl/6 mice were instrumented with 32 temperature transponders and underwent 3 weeks of training using voluntary and forced running 33 wheels. An EHS group was exposed to environmental temperatures (Tenv) of 37.5, 38.5 or 39.5...
