Relationship Between Extension Recoverability of Sportswear Materials and Human Electro-encephalogram

【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.22 Vol.22】

　Electro-encephalogram of young women was measured after flexing exercise (bending and stretching) of elbows with attached fabrics to find out the difference between strechable, recoverable fabric and unstrechable, unrecoverable fabric. Integrated percentage of α wave was analysed by FFT method, and following conclusions were obtained. There was no significant difference between strechable, recoverable fabric and unstrechable, unrecoverable fabric in the α wave attenuation at the state of eye closing. However, it was recognized that α wave attenuation occurred in more subject after flexing exercise of elbows attached with unstrechable, unrecoverable fabric.
