説明

A complex work load generator for use in cycle ergometry was computerized in order to obtain information with respect to the interaction of cardiopulmonary variables during exercise and to evaluate muscular work in practical activities. A new constant current circuit was developed to modify changes of both load resistance and internal resistance of alternator, due to the heat accumulation from energy discharge. Prior to the circuit design, the alternator output voltage, field current and the internal resistance were determined. The electric circuit was designed for both manual and computer operation, distributing the load watts to 8 channel load resistors which were arranged for binary output of computer. The TTL circuit selects the signal data of work load instruction and transfer them into each load channel. An ergometer controller data acquisition program was developed to determine the load level and program complex variation of work loads such as ramp, impulse, sinusoidal and random work load. Some applications of the ergometer system are reported and discussed for the analysis of complex physiological systems during work. obtained by both constant and progressive loads
