Purpose The purpose of this study was to effect of balance ability and the low trunk strength when application the low extremity strength exercise with abdominal respiration exercises. Methods It was conducted for six weeks with 44 healthy persons(male: 25, female: 19) and they were divided 3 groups; control group(n=15), the lower extremity exercise group(n=14), combined the lower extremity exercise with abdominal respiration(n=15). The exercise program consists of warming up, main exercises and cool down. For each change of motion in the exercise, the experimental group A proceeded to natural breathing group B for 40 seconds. To see the effect of intervention, using Functional Reaching Test for dynamic balance, One Leg Standing for static balance and Primus RS for the low trunk strength. Results Compared before and after the intervention, control group didn't show any differences but group A and group B were improved static balance, dynamic balance and strength of low trunk. There was no differences in the balance and strength between two groups. Conclusion The effect of balance and strength of low trunk were similar to that of the group with abdominal respiration group and did not perform abdominal respiration group. Therefore the combination of abdominal breathing during strength training did not affect muscle strength and balance.
