The Research Of Frequency Conversion Type Of Strength Training Equipment

Raising national's strength quality level, the advanced strength training equipment is playing the important foundation role. Strength training equipment has experienced several innovations from natural heavy item to barbell, now to all kinds of high tech strength training equipment. With using the vibration stimulation, the vibration strength training equipment can enhance the muscle biggest strength ,the explosive force , the contracture of the muscle, strengthening the coordination between the central nervous systems, enhancing the muscle reaction capacity and the coordinated ability; The vibration strength training is also advantageous to the enhancement muscle elasticity and the flexibility, also may affect indirectly the skin blood stream quantity, thus is advantageous to the weary fast restoration.The strength quality is the important constituent in the physical quality of human body, and important foundation of humanity's livelihood. With the implementation of the "Fitness Plan Summary"and "Olympic Games honor Plan Summary" , the national physical quality and athletics sports level enhancement has became two mainstream directions, what is more, the strength quality enhancement will be a key factor between the directions. In order to adapt to this kind of demand at the moment. Improve the tradition training and rating measure, Start with resolving the difficulty and key spot of the movement training practice, using the idea and measure of contemporary science and technology. Integrate the well-developed and scientific knowledge training means. Improve the scientific training and movement athletics level of Chinese athletes. Moreover positively answer the appeal about"Science and technology Olympic Games"proposed by our country. Stress to launch the research of scientific supervision about training and collect training message and research of the analytic system. With the only idea of making high science and technology produce. In order to serves well for the Olympic Games attack project, fitness for all the people, we should the better display new instrument in sports enterprise function, but the vibration strength training equipment is expensive as a result of the overseas import, we must have to research and develop our vibration strength training independently. This design concept of the body strength training appliance is as follows:a. Vibration frequency is adjustable, frequency range are from1 to 50Hz, each 1Hz of the frequency may adjust.b. The oscillation amplitude is 3mm, and the load-carrying capacity is big enough, load-bearing 300 kilograms.c. The vibration direction are determined, determines the longitudinal oscillation direction with the additional guide slot.d. The endeavour operation is simple, the cost is inexpensive, the carryhome is convenient, is advantageous for the trainer, the athlete, the scientific researcher and the promotion.This research innovation and technical key:Difficulty: Vibrates the instrument the frequency adjustable, the vibration direction is the vertical vibration, the oscillation amplitude is 3mm.Keystone: Because is the mechanical vibrations source, the noise question is this research difficulty.Innovate: The domestic independent design uses in the strength training the shake table, the vibration direction determined, vibration frequency adjustable.
