Development of multifunctional lower body pressure device

本课题的目的是：1）研制一种能对人体下体施加正、负压力，同时能自动调节人体角度的新型下体加压仪; 2）探索该仪器在未来运动科学中应用的可能性，研制新型多功能下体加压仪。其特点是：1）施加50 mmHg的正负压，2）用电动机驱动，使角度从-10 °变为+90 °，3）装有电磁制动的自行车测力计。我们研究了8名受试者在中心血容量为降低结果表明，上下肢的血管收缩反应不同，这一结果已在日本体能与运动医学学会年会上发表，并将在2002年美国《实验生物学》上发表。

The purpose of this project was 1) to develop the new instrument by which we can apply the positive and negative pressure on lower body in humans and simultaneously change the body angle by automatic regulation, 2) to explore the possibility of the application by using this instrument for the future exercise science.New multifunctional lower body pressure device was made. The feature of this was 1) to apply 50mmHg positive and negative pressure, 2) to change the angle form -10 degree to +90 degree by electric motor driven, 3) to be equipped with electric-magnetic braked bicycle ergometer.By using this device, we investigate the differences of blood flow regulation between upper limb and lower limb in the situation in which the central blood volume of 8 subjects was reduced. It was found that the responses of the vasoconstriction were different between upper and lower limbs.The results were presented in annual meeting of Japanese society of physical fitness and sports medicine and will be presented in Experimental Biology 2002 in USA.
