We describe a new support structure for respiratory gas valves for use in exercise studies. Use of this structure largely avoids problems of large inertial reactions and feelings of confinement on the part of the subject which have characterized previous systems. The support mechanism consists of a spring-reacted, pivoted boom carried on the end of a counterbalanced swinging beam. This device was designed for use on an adjustable slope motor-driven treadmill, but may be adapted to a variety of other experimental arrangements.
我们描述了一种用于运动研究的呼吸气体阀的新型支撑结构。使用这种结构在很大程度上避免了以往系统所具有的主体部分的大惯性反应和受限感问题。支撑机构由一个弹簧反作用的、枢转的吊杆组成，该吊杆安装在一个平衡摆动梁的端部。该装置设计用于可调坡度的电动跑步机，但也可适用于各种其他实验装置。
