The purpose of this study was to analyze the effect of the short-term core concentration exercise on body balance of male university students. The NO(normal eye open), NC(normal eye close), PO(pillow with eye open), PC(pillow with close eye), HR(head right), HL(head left), HB(head back), and HF(head forward) were measured using TETRAX as a body balance test. The exercise program was conducted 30 rep for 4 weeks, 3 times a week. The significance level was set at p<.05. For statistical analysis, we used SPSS 25 to calculate the mean and standard deviation, and the paired sample t-test was performed in order to verify the mean difference by group. The result is Significant differences were found in NC(p<.05), PC(p<.01), HR(p<.01), HL(p<.01), HB(p<.05) and HF(p<.01) among WDI items. Through this study, core exercise will bring about positive changes in the body balance and physical fitness of the Adults, and can provide specific data for core exercise programs.
