Benefits of technology

[0006] Therefore, the object of the present invention is to provide a method and apparatus for providing a dynamically variable resistive load during exercise that can overcome the aforesaid drawback of the prior art.

Problems solved by technology

While the aforesaid known apparatus provides a variable resistive load during exercise, it does not take into account the actual physical condition of the user during exercise.
As a result, when the resistive load is too heavy, the user is likely to get injured due to over-exertion.

Abstract

An apparatus for providing a dynamically variable resistive load during exercise includes a wheel unit, a resistance generator, a torque transfer device, an angle measuring device, and a control unit. The wheel unit rotates in response to exertion of a user-applied force during an exercise stroke. The resistance generator generates a resistive torque for resisting rotation of the wheel unit when the user-applied force is exerted. The torque transfer device transfers a fraction of the resistive torque from the resistance generator to the wheel unit. The angle measuring device detects angular rotation of the wheel unit during each exercise stroke. The control unit, in accordance with the angular rotation of the wheel unit during a current exercise stroke, controls the torque transfer device to adjust the fraction of the resistive torque that is transferred to the wheel unit.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a load for exercise equipment, more particularly to a method and apparatus for providing a dynamically variable resistive load during exercise. [0003] 2. Description of the Related Art [0004] A known apparatus for providing a resistive load during exercise includes a wheel unit, a resistance generator, an electrically controlled torque transfer device, and a control unit. The wheel unit is operable so as to rotate in response to exertion of a user-applied force during an exercise stroke. The resistance generator, such as an electric motor, is operable so as to generate a resistive torque for resisting rotation of the wheel unit when the user-applied force is exerted. The torque transfer device, such as an electromagnetic mechanical particle clutch, couples the resistance generator to the wheel unit, and is operable so as to transfer a fraction of the resistive torque from the resistance gene...
