A bicycle ergometer was constructed which, for the first time, allows the universal application of modern dynamic test procedures for the analysis of the regulatory behaviour and the physical working capacity in man. Different programs with impulse, step, ramp or sinusoidal test signals as well as with optimal multifrequent binary test signal sequences can be generated by a programmable automatic control system or by a function generator. In the automatic control system the signals are stored on punched papers and transformed into a voltage variation by a paper-tape reader. The voltage fluctuation is changed into the required brake horsepower of the ergometer by a special transducer. The actual pedalling speed is measured by a tachometer and the supplied voltage simultaneously is used for the adjustment of the work load independent of this speed. The new equipment can be used both for dynamic and static ergometric investigations with the advantage of rational and exact test procedures and the extended possibilities of application for the use in clinics, sports medicine, applied physiology and research in general.
制造了一种自行车测力计，它首次允许将现代动态测试程序普遍应用于分析人体的调节行为和体力工作能力。可编程自动控制系统或函数发生器可以生成具有脉冲、阶跃、斜坡或正弦测试信号以及最佳多频二进制测试信号序列的不同程序。在自动控制系统中，信号存储在穿孔纸上，并通过纸带读取器转换为电压变化。通过特殊的传感器，电压波动被转换为测力计所需的制动马力。实际蹬踏速度由转速计测量，并且所提供的电压同时用于独立于该速度的工作负荷调节。这种新设备可用于动态和静态测力计研究，具有合理、精确的测试程序以及在临床、运动医学、应用生理学和一般研究中的广泛应用可能性等优点。
