Abstract

Disclosed are various approaches for determining the maximum oxygen consumption of a person, also known as maximum aerobic capacity or VO2 Max. A person is positioned on a treadmill. Attached to the person is a harness configured to apply a horizontal force to the person. A work rate for the person can be calculated based at least in part on the magnitude of the horizontal force applied by the harness and the velocity of the belt. The maximum oxygen consumption for the person can then be calculated based at least in part on the previously calculated work rate.

First claim

Therefore, the following is claimed:

1. A system, comprising:
a treadmill;
a harness configured to transfer a constant horizontal force to a person on the treadmill, the harness being configured to prevent the person from falling onto a belt of the treadmill and the harness is connected to a lever arm, wherein a weight is suspended from the lever, or the harness is connected to an elastic line configured to develop the constant horizontal force as the elastic line is stretched;
a computing device in data communication with the treadmill and the harness, wherein the computing device is configured to at least:
identify a velocity of a belt of the treadmill;
identify a mass of the person; and
calculate a work rate for the person on the treadmill based at least in part on the velocity of the belt and the mass of the person.

2. The system of claim 1 , wherein the computing device is further configured to at least calculate oxygen consumption of the person on the treadmill based at least in part on the work rate.

3. The system of claim 1 , wherein the treadmill further comprises an apparatus configured to permit the person to select the velocity of the belt.

4. The system of claim 1 , wherein the harness is connected to a motor that applies a constant force by a traction line.

5. The system of claim 1 , wherein the elastic line is threaded around a pulley mounted to a frame of the treadmill.

6. An apparatus, comprising:
a treadmill;
a frame connected to a rear portion of the treadmill;
a lever connected to the frame;
a weight suspended from the lever arm, wherein the weight is configured to be slid along the lever;
a harness configured to prevent a person from falling onto a belt of the treadmill; and
a line extending from the frame, the line being coupled to a rear portion of the harness and the line being further coupled to the lever, wherein the line is configured to develop a horizontal force on the harness.

7. The apparatus of claim 6 , further comprising:
a motor connected to the frame, wherein the motor is configured to apply a constant force to the line; and
wherein the line is further coupled to the motor that applies the constant force.

8. The apparatus of claim 6 , further comprising:
a processor;
a memory; and
machine-readable instructions stored in the memory, that, when executed by the processor, cause the processor to at least:
identify a velocity of a belt of the treadmill;
identify a mass of the person; and
calculate a work rate for the person on the treadmill based at least in part on the velocity of the belt and the mass of the person.

9. An apparatus, comprising:
a treadmill;
a frame connected to a rear portion of the treadmill;
a harness configured to prevent a person from falling onto a belt of the treadmill; and
a line extending from the frame, the line being coupled to a rear portion of the harness and the line being anchored to the base of the treadmill, wherein the line is configured to develop a horizontal force on the harness and the line is elastic, such that as the line is stretched, additional force is applied to the harness.

10. The apparatus of claim 9 , further comprising:
a motor connected to the frame, wherein the motor is configured to apply a constant force to the line; and
wherein the line is further coupled to the motor that applies the constant force.

11. The apparatus of claim 9 , further comprising:
a processor;
a memory; and
machine-readable instructions stored in the memory, that, when executed by the processor, cause the processor to at least:
identify a velocity of a belt of the treadmill;
identify a mass of the person; and
calculate a work rate for the person on the treadmill based at least in part on the velocity of the belt and the mass of the person.
