DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS The present invention is directed to a method and apparatus for increasing muscle size and strength, as well as lung capacity, at low training intensities utilizing eccentric ergometry.
The apparatus of the present invention comprises means for applying a torque transfer to the human muscular system.
The apparatus is directed to an eccentric ergometer device 10, shown in FIGS.
1 2 , which includes a motor 12, a turning or pedal crank 14, at least one flywheel 16, and an adjustable seat 18.
The motor 12, turning crank 14, and seat 18 are all coupled to a frame 20 which is preferably comprised of steel, or a similar type of strong, durable material.
The motor 12 is mechanically coupled to the turning crank 14 by one or more chains 22 which may also take the form of toothed belts or cardan shafts.
The device 10 further comprises display means 24, such as a monitor, for displaying deceleration power data produced by a user's muscular system in resisting torque transfer as well as other data including, but not limited to, time elapsed, heart rate, pedal revolutions per minute, intensity level, speed, and measurement of work performed.
A magnetic sensor 26 monitors pedal speed.
In constructing the embodiment of the eccentric ergometer of the present invention which is depicted as device 10, the power train of a standard Monarch cycle ergometer may be used.
The adjustable seat 18 may comprise a recumbent seat and the device 10 may be driven, for example, by a three-horsepower direct current (DC) motor with one or more idlers between the motor 12 and the flywheel 16.
The gear ratio from the flywheel 16 to the turning or pedal crank 14 is preferably about 1:3.
75.
As previously stated, all components are mounted to a steel frame 20 for stability.
A motor controller 28 controls the motor speed and preferably has a 0 to 10 Volt output for both motor speed and load.
The magnetic sensor 26 monitors pedal revolutions per minute (rpm) which is preferably displayed to the rider/user during the training session The voltage and amperage outputs from the controller 28 are monitored through an analog-to-digital board and dedicated computer
