US 2018/0321096 A1 · EVALUATING PEDALING EFFICIENCY

Abstract

A method and apparatus for measuring and evaluating pedaling efficiency of a cyclist. Instantaneous measurements of torque exerted through crank pedal arms are correlated with crank pedal arm positions through one or more complete crank rotations. Average torque exertion on the crank arms is determined for specific sectors of the entire crank rotation and the resulting values are compared. For example, the average torque through the top half of a crank rotation is compared with the average torque for an entire crank rotation, with a comparison expressed, for example, as a ratio. A numerical result of certain comparisons is thus obtained as guidance for future training of the cyclist to improve performance.

Dependent claims

A method for evaluating pedaling efficiency of a cyclist, comprising:

(a) collecting crank torque and position data at a plurality of crank arm positions during a complete revolution of a crank arm while the cyclist is pedaling;
(b) from the collected crank torque and position data computing a first average torque produced through a top half of a pedal crank arm revolution;
(c) from the collected crank torque and position data computing a second average torque produced through a bottom half of the pedal crank arm revolution;
and
(d) comparing the first average torque to the second average torque and thus deriving a resulting number representative of the difference between the first and second average torques.
