Patent ID: 7643873

Claim:
An exercise data apparatus for use on the body of a user during exercise, comprising: an electrocardiogram detector for detecting electrocardiogram data of a user during exercise; attachment means for attaching the electrocardiogram detector onto the chest of the user; a motion detector for detecting body motion data indicative of steps of the user during exercise; a processor for calculating exercise data based on the electrocardiogram data detected by the electrocardiogram detector and the body motion data detected by the motion detector, the exercise data comprising at least one of heart rate, speed and distance, and calorie consumption of the user, wherein the processor is programmed to calculate the calorie consumption based on weight, fitness level, and heart rate of the user; and an output device for informing the user of the exercise data calculated, wherein the calorie consumption is calculated according to the formula: Calorie consumption = TI * Weight * ( instant ⁢ ⁢ HR / maximum ⁢ ⁢ HR ) - AF , wherein HR is the heart rate of the user, TI and AF are Training Index and Activity Factor, respectively, and are related to VO 2 percentage, VO 2 is oxygen consumption of the user, VO 2 max is maximum rate of oxygen consumption by the user, and VO 2 percentage is the percentage of VO 2 max being consumed by the user, and when VO 2 percentage is 50% to 60%, TI=6 and AF=400, when VO 2 percentage is 60% to 70%, TI=8 and AF=580, when VO 2 percentage is 70% to 80%, TI=12 and AF=1,000, when VO 2 percentage is 80% to 90%, TI=18 and AF=1,720, and when VO 2 percentage is 90% to 100%, TI=22 and AF=2,260.
