초록

PURPOSE: This study was to determine the changes of abdominal muscles activation according to the heel contact methods of stair ascent in healthy young adults. METHODS: 33 healthy young subjects (mean age: $26.37{\pm}9.72$ years, age range: 20-32 years) volunteered under two conditions. They were performed stair ascent with heel contact and without heel contact. The effects of heel contact methods were assessed using the surface electromyography (sEMG) analysis during stair ascent for activation of abdominal muscles (internal oblique; IO, transverse abdominis; TrA, external oblique; EO rectus abdominis; RA). The interventions were conducted over three trials in each method, and measurements were performed on each subject by one examiner in three trials. RESULTS: Our results revealed that there were significantly greater increase in the EMG activation of IO and TrA muscles in the performance of stair ascent with heel contact (p<.05) compared to those of stair ascent without heel contact. The results also showed that there were greater decrease in the ratio of abdominal muscle activation in those of stair ascent with heel contact compared with stair ascent without heel contact. CONCLUSION: These findings demonstrated that the method of stair ascent with heel contact would suggest positive evidence for improving activation of abdominal muscles.
