This study is purposed to provide the basic data necessary for developing the efficient exercise program for participants in the dance sports, by comparing the Health-related Fitness, the range of joint motion(ROM) and different results of electromyogram during balancing of participants in the dance sports whose levels are categorized for the analysis. Participants of this study were chosen from females of 20s to 30s in Busan; 78 from the player group of dance sports, 66 from the experienced group ,and 72 from the general group. Dependent variables are followings: variables of the physical strength are back muscle strength, Sit-Ups, flexibility, %Fat and Harvard step test; variables of the ROM are plantar flexion and dorsi flexion of ankle, and hip abduction; variables of lower extremity muscle’iEMG are iEMGs of tibialis anterior muscle, soleus muscle, inside gastrocnemius, and outside gastocnemius. Variables are measures by levels of participantion in the dance sports . The ROM and balancing. Results are analyzed by SPSS 12.0, using repetition t-test and one-way ANOVA. If any significance is shown, the post-test was conducted by the Scheffe method. The level of significance in denial of statistical hypothesis is p<.05. Statistical analysis shows the following results. 1) A characteristic of Health-related Fitness by participants of the dance sports is the player group shows statistically higher in muscular strength(p<.05), muscular endurance(p<.001), flexibility(p<.001) and fat percentage(p<.05) that the experienced group and the general group. However, cardiovascular endurance shows no difference among groups. 2) The ROM of participants of the dance sports tells that the player group is statistically higher in plantar flexion(p<.05) and right/left hip abduction(p<.01) that the experienced group and the general group. For dorsi flexion, the general group has a higher statistics than the experienced group. For left and right hip abduction by participants of the dance sports, right hip abduction is statistically higher than the left(p<.01) in the player and experienced group. However, the general group shows no statistical significance. while the experienced group is higher than the general group. However, outside gastrocnemius does not show any statistical significance.dance sports In conclusion, for the Health-related Fitness by levels of participation in the dance sports, the player group has better back muscle strength, Sit-Ups and flexibility, and lowest fat percentage. For the ROM, the player group has the highest plantar flexion, while the general group has the highest dorsi flexion. The player group has the highest hip abduction. In comparison of left and right hip abduction, right hip abduction is higher than the left on in the player and experienced group.
