Abstract
Although measurement of abdominal strength is important for evaluating trunk myofunction, adequate devices for these measurements have not been developed. As a consequence, the relationships between abdominal strength and abdominal muscle thickness have also not been determined. This study aimed to develop a new device for measuring abdominal strength and to examine the relationship between abdominal muscle strength and thickness. The subjects in the study included 50 young males (age, 19.1 ± 0.32 years; height, 171.0 ± 6.55 cm; weight, 69.5 ± 12.15 kg). The measurement of abdominal flexion strength had high reliability with an intra-class correlation coefficient (ICC) >0.9. The thickness of the rectus abdominis muscle was measured under two conditions using an ultrasound imaging method; relaxation and strength exertion. Abdominal muscle thickness was significantly thicker during exertion than during relaxation. Abdominal flexion strength showed a significant correlation with muscle thickness during both relaxation (r = 0.69) and strength exertion (r = 0.71). No significant difference was found between these correlation coefficients. In conclusion, the values of abdominal strength determined by our newly-developed measuring device had high reliability, with abdominal flexion strength showing a relatively close relationship with the thickness of the rectus abdominis during strength exertion and relaxation.

Maintaining posture (Michael, Erik, & Udo, 2010). Their development is important, for athletes, and for the general population. It is absolutely necessary to maintain and increase abdominal strength in order for the rectus abdominis muscle to function properly during the activities of daily living. It is difficult to measure abdominal flexion strength of the rectus abdominis muscle, and useful devices to measure parameters such as grip or leg strength have not been developed. It is necessary to develop reliable devices for measuring abdominal strength
