ROTATOR MUSCLE EXERCISE APPARATUS

摘要

This invention relates to a new rotator muscle exercise apparatus. The apparatus comprises a pair of rotatable foot rests, each foot rest operably connected to a separate air cylinder whereby the pressure of the air within the cylinder is controlled by the rotation of the foot rests. The apparatus allows for development of rotator muscles with particular reference to resistance exercise, including for example strength training, specificity of training, rehabilitation, and preventive conditioning programmes. The apparatus will produce muscle contractions of varying intensities through a full range of motion, yet is simple in design, light-weight and portable. It uses no auxiliary fluid supply source and is completely selfcontained and easy to operate.
