A study on Cardiovascular function and blood lactate of the Dance Major students

&nbsp;&nbsp;The purpose of this study is to investigate the cardiovascular function and blood lactate of female by part of dance major in university.<BR>&nbsp;&nbsp;For this purpose a total of 32 female students, attending university K in Seoul participated in the study.
