A New Method to Increase in Sex Steroids Hormone in Old Aged Men, Focusing on BUDO.
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.38 Vol.38】
ABSTRACT
The aim of this study was to investigate the effects of Nihon Kendo kata on the secretion of sex steroid hormone in older and young kendo athletes. The subjects perfumed the 10 sets of Uchitachi and Shitachi each in Nihon Kendo kata. Measurement of rated perceived exertion (RPE) and heart rate and collection of blood sample were undergone before, immediately, 15, 30 and 60 minutes after kata. Blood glucose, lactate, ACTH, DHEA and free testosterone levels were measured. The Kata significantly increased (p<0.05) RPE, heart rate and glucose. Furthermore, the kata increased the metabolism of ACTH and DHEA. There was no change in the concentration of free testosterone after kata. Aging did not affect the hormonal response to the kata. These results suggest that Nihon kendo kata could stimulate ACTH-DHEA systems.
