Method of obtaining optimum load value for a user of an exercise device.

摘要

The method of using an ergometer enables a user to select a physical strength program and a weight reduction program with the selected program reflecting the age, sex and the present physical condition of the user. The method may be implemented with an ergometer including an eddy current brake having a rotor assembly (5,6) including an iron material having a carbon content of 0.12% or less and a silicon content of 0.35% or less, a stator (7) provided in the rotor assembly, a plurality of exciting coils (8) provided on the stator, and a power source (9) for energizing the exciting coils (8). The ergometer may include an input panel (11) for inputting physical attributes of the user, e.g. age and sex, a pulse sensor for measuring the heart rate of the user at rest and during exercise on the ergometer, an arithmetic control circuit for calculating a training program and heart rate range and for controlling the eddy current brake to present a load to the user which will maintain the user's heart rate in a predetermined range.
