Abstract:
1. A measurement apparatus that measures force being applied to a man-powered machine, comprising: a strain detecting part that detects strain of a crank of the man-powered machine configured to transmit force being applied from a user through the crank and one gear selected among one or more gears; a sensor that detects the crank passing through a predetermined position; and a control part, wherein: the control part calculates a rotation angle of the crank based on an elapsed time from a time the crank passes through the predetermined position that the sensor has detected; the control part calculates force applied to the crank based on a strain amount of the crank that the strain detecting part has detected; the control part associates the rotation angle with the force applied to the crank to calculate distribution of the force applied from the user; the crank connects a pedal and a crankshaft; and the strain detecting part is disposed on the crank.
