Both currents used a pulse rate of 50 Hz. The perceived discomfort experienced with each type of electrical stimulation was quantified by the use of a visual analogue scale. An isokinetic dynamometer (Cybex) was used to assess peak torque. Paired t-test demonstrated that inferential stimulation was perceived to be significantly less uncomfortable than low-frequency stimulation and that inferential stimulation produced a significantly greater peak torque of muscle contraction than low-frequency stimulation. This study indicates that inferential stimulation can produce an electrically induced muscle contraction which is stronger and less unpleasant than low-frequency stimulation.</p>","PeriodicalId":76534,"journal":{"name":"Schweizerische Zeitschrift fur Sportmedizin","volume":"41 1","pages":"15-9"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19453370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of 57 mountaineers ascending from 1170 m to 4559 m within 22 to 77 hours, 24 developed acute mountain sickness (AMS) and 16 developed high altitude pulmonary edema (HAPE). In 14 cases HAPE was preceded by symptoms of AMS. Independently of the amount of fluid intake, which varied from 2 to 4 l/24 h in these studies, subjects developing AMS showed decreased diuresis and natriuresis compared to healthy controls with similar fluid intake. Higher fluid intake resulted in greater urine output but did not prevent AMS. Higher plasma levels of aldosterone at rest and greater exercise-induced rises of plasma aldosterone and vasopressine may explain the increased water and salt retention in subjects with AMS. Whether these hormonal changes are secondary to a more severe hypoxemic stress or present a primary cause of AMS remains to be determined.</p>","PeriodicalId":76534,"journal":{"name":"Schweizerische Zeitschrift fur Sportmedizin","volume":"41 1","pages":"7-13"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19453373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
