This study was intended to manifest how female adults` regular swimming could exercise effect on the cardiovascular function, The measurement was taken at the Seoul YMCA Physical Strength Center over 7 months, centering around 1992. female members who had participated in the center`s Swimming Program The One-way ANOVA was adopted as a methodology in order to find out any difference among the different groups of people. For this purpose, at first, the 1992. volunteers were grouped into 8 different divisions(between 29 year olds and 60 years olds) according to their ages and 4 different divisions(under one year, 1~2 years, 2~3 years, and 3 years or more) according to years of involvement in exercise Besides, ANCOVA was used with exclusion of age division in order to ascertain the effects that pure swimming participation had on those variables concerned, The conclusion drawn on the basis of the results of the study through the methodology and data analysis procedure stated above were as follows. 1. The study indicated that swimming participation exerted a very significance(p＜.05) effect upon the change or the heart rate, as it was conducted with the exclusion of age variables so as to certify whether pure swimming participation affected anything upon the change of the heart rate in a normal situation or not 2. As a result of verifying what effects swimming participation had on the change of the vital capacity, through the exclusion of age variables, it was made clear that the participation had no effect upon the change of the vital capacity. 3. We could not found reliable difference of maximal oxygen uptake of among groups. As a result of verifying what effects swimming participation had on the change of the maximal oxygen uptake, through the exclusion or age variables, it was made clear that the participation had no effect upon the change of the maximal oxygen uptake.
