Development of multifunctional lower body pressure device

这个项目的目的是：1)开发一种新的仪器，可以对人体下半身施加正负压，同时通过自动调节改变身体角度，2)探索利用这种仪器在未来运动科学中的应用可能性。研制了一种新型多功能下身压力装置。其特点是：1)施加50mmHg的正负压；2)通过电动机驱动使角度从-10度变为+90度；3)配备电磁制动自行车测力仪。通过该装置，我们研究了8名受试者在中心血容量减少的情况下，上肢和下肢血流调节的差异。结果发现，上肢和下肢对血管收缩的反应不同。该研究结果已在日本体能与运动医学学会年会上发表，并将在美国《实验生物学2002》杂志上发表。

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.
