A Strength Training Machine with a Dynamic Resistance Control Function Based on Muscle Activity Level

Abstract

A unique machine for strength training is introduced in this chapter. This training machine dynamically controls the amount of electronically generated resistance to provide a varying resistance force that follows a desired pattern during the exercise. This pattern or trajectory of desired muscle activity levels can be easily set prior to exercise through an interactive panel on the computer screen. It is predicted that this technology could facilitate more safe and effective strength training. The methodology for the muscle activity-based resistance control and the mechanism of the proposed system are detailed using a leg press prototype machine. The unique training features offered by the prototype are presented with data recorded from demonstrations and experiments.
