High efficiency strength training apparatus

Abstract

In one preferred embodiment, the present invention provides an exercise apparatus in which an impingement member is driven between a selectable start point and a selectable endpoint. When coupled with suitable instrumentation and electronic circuitry, the inventive strength training device allows the measurement, tracking, and computation of force exerted, repetitions performed, measurement and display of position, velocity, acceleration, work, impulse, etc. In addition, archived data can be used to show improvement or problem areas as well as provide an indication of the quality of each repetition and the quality of the workout in general. Such an exercise apparatus comprises: a frame including a base; a linear actuator supported from the frame; an impingement member movable relative to the frame and driven by the actuator; and a controller for controlling the actuator.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an efficient system and method for exercise testing and prescription. More particularly, but not by way of limitation, the invention provides an exercise apparatus such that the performance of a user can be precisely monitored or controlled.[0003]2. Background of the Invention[0004]People exercise for any number of reasons, such as to improve performance in a sport, to lose weight, general conditioning, to feel better, or even as a social activity. Since many people find it difficult, if not impossible, to maintain an exercise regimen for any meaningful period of time, measuring performance and producing noticeable gains in the shortest period of time are an important part of motivating an individual to maintain an exercise program.[0005]Exercise machines for aerobic conditioning have provided measurements of a user's performance for many years. Even if such machines have historically in...

AI Technical Summary

Benefits of technology

"The present invention provides an exercise apparatus that can measure and track the force exerted, repetitions performed, and position, velocity, acceleration, work, and impulse during exercise. This allows for real-time or near real-time feedback and customization of the user's exercise program. The apparatus uses an impingement member driven by a linear actuator and a controller to control the actuator. The invention also draws user information from a database to customize workout sessions for each user. The use of load sensors and robotic control of the linear actuator ensures consistent and repeatable measurements. The technical effects of the invention include improved strength training, testing, and prescription."

Problems solved by technology

Traditionally strength training devices have not provided users the same benefit.

Unfortunately, tracking a strength training regimen by only weight and repetitions is very likely misleading and may actually de-motivate a user rather than encourage.

Further, simply adjusting the weight and counting repetitions do not readily allow an individual to identify day-to-day factors which can effect the number of times the user can lift a given weight.

Further still, merely counting repetitions does not reflect intra-rep performance factors, i.e., power, inertia, relative concentric / eccentric speeds, etc.

However, a primary reason many people abandon an exercise program is the lack of discernible improvement.

Disadvantages of the Noffsinger device include: the horsepower of the motor required for high-end users is substantial; the device is relatively heavy; the range of motion is limited because it is mechanically set; and sinusoidal movement of the impingement member is inherent in the device.

Finally, Noffsinger does not suggest or utilize the use of real-time feedback to control the exercise motion during its execution.
