Prior to and following supplementation, subjects performed three 100-m freestyle sprint swims (long course) with 60 s rest/recovery between heats. In addition, subjects performed three 20-s arm ergometer maximal-effort sprint tests in the prone position with 60 s rest/recovery between sprint tests. Significant differences were observed among swim times, with Cr subjects swimming significantly faster than P subjects following supplementation in Heat 1 and significantly decreasing swim time in the second 100-m sprint. There was also some evidence that cumulative time to perform the three 100-m swims was decreased in the Cr group. Results indicate that 9 days of Cr supplementation during swim training may provide some ergogenic value to competitive junior swimmers during repetitive sprint performance.","PeriodicalId":14321,"journal":{"name":"International journal of sport nutrition","volume":"7 4","pages":"330-46"},"PeriodicalIF":0.0,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1123/ijsn.7.4.330","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20335246","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}

The level of carbonation in a 6% carbohydrate (CHO) electrolyte drink was systematically varied (0, 1.1, 2.3, and 3.0 volumes of CO2), and its impact was assessed in 52 adults following 30 min of exercise. The perception of carbonation intensity closely tracked the differences in physical carbonation levels presented, with all perceived intensities significantly different from each other (p < .01). Overall sensory acceptability, perceived thirst quenching, and perceived sweetness were significantly lower for 2.3-vol CO2 and 3.0-vol CO2 than for 0-vol CO2 and 1.1-vol CO2 (p < .01). Perceived throatburn was significantly higher for 2.3-vol CO2 and 3.0-vol CO2 than for 0-vol CO2 and 1.1-vol CO2 (p < .01). Total fluid intake for 0-vol CO2 and 1.1-vol CO2 was significantly higher than for 2.3-vol CO2 (p < .05), which was significantly higher than for 3.0-vol CO2 (p < .05). It was concluded that levels of carbonation equal to or in excess of 2.3-vol CO2 negatively impact drink acceptability and voluntary fluid intake.","PeriodicalId":14321,"journal":{"name":"International journal of sport nutrition","volume":"7 4","pages":"286-97"},"PeriodicalIF":0.0,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1123/ijsn.7.4.286","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20335242","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}

Eleven resistance-trained males performed cycle ergometry to deplete quadriceps muscle glycogen stores, followed by 48 hr of a high (HICHO) or a low (LOCHO) CHO diet. Subjects then performed five sets each of squats, leg presses, and knee extensions (resistance = 15 RM) to failure. Blood samples were taken before and during exercise for determination of glucose and lactate (LA). No differences in performance (repetitions x weight lifted) were observed (HICHO = 15,975 +/- 1,381 and LOCHO = 15,723 +/- 1,231 kg). Blood glucose was significantly higher after exercise for HICHO compared to LOCHO (HICHO = 4.8 +/- 0.2 vs. LOCHO = 3.9 +/- 0.2 mmol.L-1). No differences in LA accumulation were observed. The data indicated that preexercise CHO status did not affect resistance exercise performance. Further, the differences in blood glucose and the similarity in LA responses suggest that glycolysis was maintained in the LOCHO condition, and there may have been an increased reliance on blood glucose when preexercise CHO status was low.","PeriodicalId":14321,"journal":{"name":"International journal of sport nutrition","volume":"7 3","pages":"185-96"},"PeriodicalIF":0.0,"publicationDate":"1997-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1123/ijsn.7.3.185","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20228367","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}

They used a variety of nutrition resources, but only 36% had attended nutrition workshops. Almost all coaches were interested in learning more about specific nutrition topics. More experienced coaches attended nutrition workshops and felt more informed about weight loss and sport nutrition. The mean percentage of correct responses to questions about weight loss was 64%, training diets 59%, dehydration 57%, body composition 52%, and eating disorders 80%; the mean score for healthy attitudes about weight loss was 69%, training diets 34%, dehydration 29%, body composition 70%, and eating disorders 69%.
