All animals were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The DE group was exercised on treadmill for 1 hour just before being sacrificed. Animals in the AE group were allowed to take a rest for 2 hours after being exercised like the DE group. Glucose and free fatty acids were compared in plasma. Glycogen and triglyceride were compared in liver and skeletal muscle. Protein levels were compared in plasma, liver, and skeletal muscle. Compared with the B<jats:sub>6<\/jats:sub>+ group, plasma glucose levels of the B<jats:sub>6<\/jats:sub>\u2013 group were significantly lower before and after exercise. Muscle glycogen levels of the B<jats:sub>6<\/jats:sub>\u2013 group were significantly lower than those of the B<jats:sub>6<\/jats:sub>+ group regardless of exercise. The liver glycogen level of the B<jats:sub>6<\/jats:sub>\u2013 group was also significantly lower than that of B<jats:sub>6<\/jats:sub>+ group during and after exercise. Before exercise, plasma free fatty acid levels were not significantly different between the B<jats:sub>6<\/jats:sub>+ and B<jats:sub>6<\/jats:sub>\u2013 groups, and plasma free fatty acid levels of the B<jats:sub>6<\/jats:sub>\u2013 group were significantly lower during and after exercise. The muscle triglyceride level of the B<jats:sub>6<\/jats:sub>\u2013 group was significantly lower than that of the B<jats:sub>6<\/jats:sub>+ group before exercise, and there were no differences between B<jats:sub>6<\/jats:sub>+ and B<jats:sub>6<\/jats:sub>\u2013 groups during and after exercise. Liver triglyceride levels were not significantly different between B<jats:sub>6<\/jats:sub>+ and B<jats:sub>6<\/jats:sub>\u2013 groups. Plasma protein levels of the B<jats:sub>6<\/jats:sub>\u2013 group were lower than those of B<jats:sub>6<\/jats:sub>+ before and after exercise. Muscle protein levels of the B<jats:sub>6<\/jats:sub>\u2013 group were not significantly different from those of the B<jats:sub>6<\/jats:sub>+ group. Liver protein levels of the B<jats:sub>6<\/jats:sub>\u2013 group were significantly lower than that of the B<jats:sub>6<\/jats:sub>+ group after exercise. Liver protein levels of both B<jats:sub>6<\/jats:sub>+ and B<jats:sub>6<\/jats:sub>\u2013 groups were not significantly changed, regardless of exercise. Thus, it is suggested that vitamin B<jats:sub>6<\/jats:sub> deficiency may reduce fuel storage and utilization with exercise in physically trained rats. <\/jats:p>","DOI":"10.1024\/0300-9831.78.2.64","type":"journal-article","created":{"date-parts":[[2008,9,11]],"date-time":"2008-09-11T02:30:35Z","timestamp":1221100235000},"page":"64-69","source":"Crossref","is-referenced-by-count":1,"title":["Vitamin B<sub>6<\/sub> Deficiency can Reduce Fuel Storage and Utilization in Physically Trained Rats"],"prefix":"10.31083","volume":"78","author":[{"family":"Choi","sequence":"first","affiliation":[{"name":"Dept. of Food & Nutrition, Duksung Women\u2019s University, Seoul 132-714, Korea This study was supported by 2007 Research fund of Institute of Natural Science Research, Duksung Women\u2019s University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Cho","sequence":"additional","affiliation":[{"name":"Dept. of Food & Nutrition, Duksung Women\u2019s University, Seoul 132-714, Korea This study was supported by 2007 Research fund of Institute of Natural Science Research, Duksung Women\u2019s University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","container-title":["International Journal for Vitamin and Nutrition Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0300-9831.78.2.64","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T02:11:13Z","timestamp":1723169473000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/IJVNR\/78\/2\/10.1024\/0300-9831.78.2.64"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,3,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2008,3,1]]}},"alternative-id":["10.1024\/0300-9831.78.2.64"],"URL":"https:\/\/doi.org\/10.1024\/0300-9831.78.2.64","relation":{},"ISSN":["0300-9831","1664-2821"],"issn-type":[{"type":"print","value":"0300-9831"},{"type":"electronic","value":"1664-2821"}],"subject":[],"published":{"date-parts":[[2008,3,1]]}}}
