초록

PURPOSE: The purpose of this study was to investigate the effects of supplementary verbal encouragement according to the gender on the activation of abdominal muscles during performance of crunch exercise in healthy subjects. METHODS: A Total of 32 healthy subjects (15 male and 17 female) were randomly allocated to two conditions, crunch exercise with Ki-hap and verbal encouragement with same gender (CKVS) and crunch exercise with Ki-hap and verbal encouragement with different gender (CKVD). The interventions were conducted over three trials in each condition, and measurements were performed on each subject by one examiner in three trials. The activation of rectus abdominis, external oblique, internal oblique, and transverse abdominis muscles were evaluated using electromyography (EMG) during performance of crunch exercise with Ki-hap and verbal encouragement with same gender or different gender, respectively. RESULTS: The results showed that there were no significantly difference in the activation of all abdominal muscles in those of the CKVS compared with the CKVD (p>.05). The results also showed that there were no significantly difference in the ratio of muscle activation at global muscle to that at local muscle between two conditions (p>.05). CONCLUSION: These findings demonstrated that application of the supplementary verbal encouragement by gender does not affect to activate the abdominal muscles of subject to perform a movement, at the same time, it would suggest positive evidence for improving activation of abdominal muscles.
