Abstract
A cyclic power monitor measures a cyclically applied force applied by animal muscle power to a device and calculates the work done by the application of the force. The time between cyclic applications of the force is calculated to produce a value which may be used to divide the calculated work to calculate applied power. An indicating device may be employed to indicate departure in applied power from a predetermined value. A cadence alarm may be employed by itself or in combination with the cyclic power monitor to indicate departures in cadence of the pedalling effort from a predetermined value of cadence. In addition, departures in the force applied to the device from a predetermined force may also produce an indication for the operator.
Claims7
Apparatus for measuring athletic performance of a bicycle rider comprising:
- means for sensing a force on a pedal of a bicycle effective to produce a force signal related to a force applied to said pedal by said bicycle rider;
- means responsive to said force signal for detecting a predetermined event in each rotation of a pedal crank of said bicycle and for producing an output signal in response;
- means responsive to said output signal for calculating a period between said events;
- and
- means responsive at least to said period for calculating at least one parameter of said athletic performance.
