Acquisition -control sequence diagram for controlling the cycle ergometer through the wearable unit with the help of an exter-nal computerFigure 2 Acquisition -control sequence diagram for controlling ... Results: We tested the wearable unit in nine people to assess its suitability to control cycle ergometer exercise. The results confirmed that the unit could successfully control the ergometer workload ... exer- cise. To implement such units, the workload control func- tion must be embedded into the wearable units, and consequently the units can output control signals to the exercise machines to set
