Abstract
The objective of this study was to clarify the effects of men's swimsuits on swimming position and muscle activity of body trunk in gliding motion. For this objective, a swimming experiment to measure electromyogram and gliding position in sagittal plane simultaneously was conducted for 3 types of men's swimsuit (A, B and C). Next, we compared experimental results one-on-one between the swimsuits by ANOVA. The results of the experiment and ANOVA showed that in wearing Swimsuit C, compared to Swimsuits A and B, hip became lower to shoulder (p<0.05), the hip joint became more extended (p<0.05), and the muscle activity of ES (Erector Spinae) and drag coefficient had tendency to decrease. In addition, we established a new index for the effect of body trunk support, which corresponds to the muscle activity of ES considering the change in the hip joint angle. We confirmed statistically that Swimsuit C had effects of extending hip joint and/or reducing the muscle activity of ES (p<0.05). The reason for this was considered to be that the Swimsuit C helped the hip extensor muscles.
