The purpose of this study is in proving basic fundamental materials for sports aerobic players to improve one`s competitive ability and provide continuous materials to help these athletes by studying the self-esteem level and body-consciousness of the athletes through their career record, prize winning records and subjective health conditions. Total subject for this study was a total of 107 athletes, who were all chosen at random in Seoul and Busan area, where 72 athletes were middle school or high school students and the other 35 athletes were either college or Self-Esteen Scale (SES) survey examination, which was originally designed by Rosenberg (1965), but was later adapted and generalized by Kim, Gwi-bong, Kim, Young-su, Kang, Sung-gu, Park, Joo-young, and Kim Young-ho in the year 2000. We also conducted a Body-Consciousness survey testing, which was originally designed by Miller, Murphy and Buss in 1981, and translated into Korean by Kang, Myung-ok in 1991. We used the SPSS Windows 10.0 program to process the materials from the experiment of this study and practiced statistical techniques like the examination of the mean figure, standard differentials, reliance analysis, frequency analysis, t-testing and variable analysis to obtain the results of the experiments. The results and the conclusion of the study are as follows. First, there was a difference in the level of self-esteem and body-consciousness according to aerobic athletes various career experiences. Also, athletes with longer career experience showed high-level readings in self-esteem(p<.05) and in physical capability(p<.05), a minor factor in body-consciousness level, and showed similar difference in the statistical readings. Second, there was a difference in the level of self-esteem and body-consciousness according to aerobic athletes various prize-winning records. But, the athletes with winning experience, compared with the athletes with no winning experience, only showed slight difference in the level of self esteem(p<.05), and showed similar differences in the statistical readings. Third, there was a significant difference in the level of self-esteem and body-consciousness according to aerobic players various subjective health conditions. Also, a group of athletes who thought their subjective health condition was good showed high level readings in self-esteem(p<.05) and in physical capability(p<.001), a minor factor in body-consciousness level, compared to the group of players who thought their subjective health was bad, and showed similar differences in the statistical readings as well. If we generalize the results from the study, sports aerobic athletes professional life has a meaningful effect on the level of self-esteem and body-consciousness, and we found out that, players with longer career experience, abundance of playing experience, and people with high awareness of self-physical fitness, tend to show high level of self-esteem and physical awareness. This will elevate the confidence level of the aerobic sports players and shows us that the increase in the physical activity through sports aerobics has a positive effect on the physical status, satisfaction and awareness of each individual aerobic athletes.
