Eight elite college gymnasts were served as the subjects of this study.

The EMG signals of latissmius dorsi and erectorspinae muscles were collected by BIOPAC Myo-electrical signal system and the kinematics data was recorded by FASTEC IMAGING High-speed camera The Friedman and Wilcoxon Nonparametric statistical test were used to compare all the variables at a .05 significant level. The results are as follows: There were significant different in latissmius dorsi and erectorspinae muscle EMG signals among the different back hyperextensions. By the results of the experiment, we found that back hyperextension exercise on the bed was the best movement among the different movements. When we performed the back hyperextension exercise, the strength of the latissmius dorsi and erectorspinae were influenced by the posture of body and training equipments.

碩士 === 國立臺灣師範大學 === 體育學系在職進修碩士班 === 97 === Abstract
The purpose of this study was to compare the EMG signal among different back hyperextension movements of all stages. Eight elite college gymnasts were served as the subjects of this study. The latissmius dorsi and erectorspinae muscles groups were monitored in this study when the gymnasts worked in three different back hyperextension movements (face down on the bed and face down on the Roman chair gestures). The EMG signals of latissmius dorsi and erectorspinae muscles were collected by BIOPAC Myo-electrical signal system and the kinematics data was recorded by FASTEC IMAGING High-speed camera The Friedman and Wilcoxon Nonparametric statistical test were used to compare all the variables at a .05 significant level. The results are as follows: There were significant different in latissmius dorsi and erectorspinae muscle EMG signals among the different back hyperextensions. By the results of the experiment, we found that back hyperextension exercise on the bed was the best movement among the different movements. When we performed the back hyperextension exercise, the strength of the latissmius dorsi and erectorspinae were influenced by the posture of body and training equipments.
