Comparison of two abdominal training devices with an abdominal crunch using strength and EMG measurements

摘要

Background. The purpose of this study was to compare the training effects of the Ab-Flex(F), Ab-Roller (R) and standard crunch (C) on EMG production, isometric maximum voluntary contraction (MVC), and isokinetic average peak torque at 30 deg/sec (ISO) of the abdominal muscles. It was hypothesized that the training devices would have similar value in a strength training program. Methods. Experimental design: this was a prospective study Involving 18 training sessions of progressively increasing rep- Etitions.
