Description
Technical field:
The present invention relates to mechanical field, relate in particular to load work against resistance devices such as athletic training and muscular training device, particularly a kind of whole range.
Background technology:
At sports field; The training muscular strength is mainly realized through multi-form barbell, dumbbell, kettle-bell, gymnasium apparatus and various anti-deadweight exercise (run, jump, throw); In the prior art; It is that master's the world vigorous and graceful associating association carries out with various different Multi Role Aircrafts and the single function machine that physical efficiency association is created with U.S. Mr. Wei De that exercise for power develops into utilization, and its principle all is that the mode of utilizing gravity block to increase weight is trained muscle strength.But when tendon spurred limbs around joint motions, the angle between flesh line of pull and moving point and the articulation center line constantly changed, and moment of muscle power also constantly changes in the contraction of muscle process, and corresponding, the moment of resistance changes thereupon.Concrete, tendon pulling limbs around joint motions in each angle of process, the drag loading that movable limbs bore is different, the contraction train on that muscle obtains in the whole range of movement is different.Can training aids and lack the anti-resistance body of weight (load) such as whole range in the prior art, not the moment of resistance such as applications and etc. the mode of weight reach the maximum efficiency of muscular training.At 20 beginning of the eighties in the end of the century, Germany has invented the detection that " waiting tester " dropped into medical diagnosis patient muscle function at first.Its principle is to make muscle under the constant relatively situation of speed, carry out the contraction that length is elongated or shorten by instrument; Even the flesh angle of pull changes; In whole range of movement, under the moment of resistance situation that equates, endure the resistance of equal load all the time to the fullest extent around the center of circle; Observe the condition of the injury of muscle under certain angle, diagnose, speed can be regulated fixing; So claim the constant speed tester again, comprise etc. that the trend heart shrinks and waits and move the variation that two kinds of instruments of centrifugal contraction (CYBEX & BIODEX) are diagnosed limbs power in the joint rotation process.Patient can show through computer through unit head transmission data if pain or strength decline occur in certain angle at once again, reaches the purpose of the diagnosis state of an illness.But dark tested person environmental condition restriction, cost of equipment is expensive, and the sportsman freely trains muscle but can't realize.
Summary of the invention:
