Abstract

A method for predicting athletic performance for a subject, the method comprising: obtaining first heart rate data for varying speed, constant incline running; obtaining second heart rate data for varying incline, constant speed running; determining a first power per change in speed at the constant incline; determining a second power per change in incline at the constant speed incline; predicting athletic performance in response to the first power and the second power.

Claims

1. A method for predicting athletic performance for a subject, the method comprising:

obtaining first heart rate data for varying speed, constant incline running;

obtaining second heart rate data for varying incline, constant speed running;

determining a first power per change in speed at the constant incline;

determining a second power per change in incline at the constant speed incline;

predicting athletic performance in response to the first power and the second power.

2. The method of claim 1 wherein determining the second power per change in incline includes computing:

P/dV_y=G*Mr*0.3238e−

3.

3. The method of claim 2 wherein determining a first power per change in speed includes computing:

power per change in heart rates as;

P/dHR=(P/dV_y)/(dHR/dV_y)

where dHR/dV_y is determined from the second heart rate data for varying incline.

4. The method of claim 3 wherein determining a first power per change in speed includes computing:

P/dVx=(dHR/dVx)*(P/dHR)

where dHR/dVx is determined from the first heart rate data for varying speed.

5. The method of claim 1 further comprising determining athletic efficiency for the subject, the predicting athletic performance being in response to the athletic efficiency.

6. The method of claim 5 wherein the athletic efficiency is aerobic efficiency computed as:

Effa=((Pideal/dVdotO2)/((dHR/dVdotO2))/(Papplied/dHR)

where (Pideal/dVdotO2) is aerobic power per rate of oxygen consumed a constant for human aerobic power conversion;

(Δ

HR/dVdotO2) is measured for the subject; and

(Papplied/dHR) is measured for the subject as applied power used to change elevation.

7. The method of claim 5 wherein the athletic efficiency is stride efficiency computed as:

Effs=1−

((P/dVx)/(P/dVy))

where (P/dVx) is power to run on flat ground and (P/dVy) is power to run in a vertical direction.

8. The method of claim 1 wherein:

predicting athletic performance includes receiving a desired heart rate from the subject and a desired course;

and computing a speed at which the subject runs the course to maintain the desired heart rate.

9. The method of claim 8 wherein:

the speed is computed for multiple sections of the course.

10. The method of claim 8 wherein:

the speed is calculated as

(Vx(i+1))=(HR_in(i+1)−

HR_rest)/(P/dV_y)−

((P/dV_y)/(P/dV_x))*(Alt(i+1)−

Alt(i))/(Dist(i+1)−

Dist(i)).

11. The method of claim 1 wherein predicting athletic performance in response to the first power and the second power includes predicting athletic performance for multiple courses.

12. The method of claim 1 further comprising:

for a second subject;

obtaining first heart rate data for varying speed, constant incline running;

obtaining second heart rate data for varying incline, constant speed running;

determining a first power per change in speed at the constant incline;

determining a second power per change in incline at the constant speed incline;

predicting athletic performance of the second subject in response to the first power and the second power;

comparing athletic performance of the subject and the second subject.
