The diets contained either 125 or 8 meq potassium\/kg, respectively. Rats fed the low-K diet gained weight at only one-third the rate of controls (1.7 vs. 5.2 g\/day), and their skeletal muscle and plasma potassium levels were reduced by 28 and 47%, respectively. When run to exhaustion at either 15 or 20 degrees C, low K+-fed rats accomplished less than one-half of the work done by the controls (26 vs. 53 kg. m) but exhibited a markedly greater rate of heat gain per kilogram-meter of work than controls (0.12 vs. 0.05 degrees C)ambient temperature of 20 degrees C, the rats of the low-K+ group despite large differences in body weight (-25%), run time temperature and twice (33 vs 17%) the mortality rate of the controls. Postexercise increases in circulating potassium (less than 90%) of heat-injured rats raised the plasma levels of low K+-fed rats to normal (5.9 +\/- 2.2 meq\/l). These results appear to characterize the existence of an insidious and, therefore, undocumented form of fatal exertion-induced heat illness. <\/jats:p>","DOI":"10.1152\/jappl.1981.51.1.8","type":"journal-article","created":{"date-parts":[[2017,12,25]],"date-time":"2017-12-25T02:39:38Z","timestamp":1514169578000},"page":"8-13","source":"Crossref","is-referenced-by-count":14,"title":["Effect of low-potassium diet on rat exercise hyperthermia and heatstroke mortality"],"prefix":"10.1152","volume":"51","author":[{"given":"R.
