DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device which enables the achievement of extending various muscles of the human body, through all of the means known for muscular elongation, as follows: STATIC (without movement), DYNAMIC or BALLISTIC (with motion), and the 3s or PNF METHOD.
At the present time, the devices existing for muscular elongation do not satisfy the requirements of the user, inasmuch as they only operate on isolated groups of muscles, using only one type of elongation, namely the STATIC, thus making further progress impossible. In addition to the face that they require excessive and onerous effort, inasmuch as they generally are activated by a cranking mechanism, they limit the movements of the user, so that the latter, not having any point of support or place of attachment, to maintain his balance or to extend his other muscles, has no options with regard to other types of exercise. This being so, outside help is almost always required to assist the user in achieving the range of motion.
The present invention has been developed with the aim in mind of solving all of the problems mentioned above, the main objective being to make it possible for the user to fully use and apply to all parts of his body exercises for muscular elongation and muscular flexion, through gentle, safe, and smooth movements. When appropriately positioned, the user will obtain perfect harmony of the leg and thigh muscles, the spinal column being unhindered and protected, without risk of muscular twisting or strains. Moreover, the device is able to block the internal leg muscles, once having been extended to the limits of their flexibility, thus inducing relaxation of other muscles used in executing movements; thus they are not unduly stretched, and most importantly, avoid stress on the spinal column. In addition to providing for the harmonious functioning and easement of the body, the device is easily operated, providing support for the hands in all positions of operation. Thus the device allows for harmonious and progressive exercises, facilitating conditions for rhythmic and controlled breathing, which are so necessary in elongation exercises.
The device consists of a structure upon which a movable car operates. When this is pulled it activates two leg supports, which open to form an angle of 180 degrees, the effort required being sufficiently diminished by a load reducing mechanism. The device makes possible gentle and rhythmic movements of the body. These result in the simultaneous elongation of the inside thigh muscles, as well as those of the back, shoulders, arms and hands, by means of all the types of muscular elongation heretofore specified. When the car is pulled the inside muscles of the legs (thighs, knees, calves and feet) and when the legs are drawn together all of the muscles of the back, trunk, shoulders, arms and hands are extended, the latter gripping the parallel bars of the car. The effort required to move the car is greatly reduced by the load reducing mechanism, both in the case when the car is being pulled, as well as when the leg supports are being pulled together, thus protecting the spinal column. The simultaneous elongation of the leg and back muscles, as well as those of the back, arms, and hands may also be effected using the 3S or PNF method, which consists of a three-mode operation: 1) simple elongation, 2) contraction without muscle motion, and 3) relaxation, yielding greater results than those hitherto described. This method is most effective with respect to the development of flexibility, which is defined as the range of voluntary movement of a joint, or combination of joints in any determined direction. It helps muscular elasticity and permits a more ample range of motion for the different parts of the body. Muscular elongation, on the contrary, is characterized by half the range of muscle motion. The 3S or PNF method is widely used in physiotherapy exercises in cases of distension and contraction of the muscles.
The invention may better be described by the following detailed explanation t
