Study On The Movement Effect Of Two Kinds Of Upper Limb Traction Devices

The national fitness path is a set of sports facilities,which is laid in the environment of more intensive living and suitable for leisure and fitness,which is not much occupied,economical and practical,and can be used free of charge.With the popularity of the nationwide fitness path in recent years,it has been recognized by the broad masses of the people.The literature shows that more than half of the people who participate in the national fitness path are hoping to strengthen the body through the national fitness path,while the rest are mainly leisure and entertainment.But the most important purpose of the national fitness path is fitness.However,at present,a small study on the fitness effect of the national fitness path to its audience has found that the effect of the national fitness path is not significant for the improvement of the physical function of the elderly,so the existing fitness path is necessary to improve the design..Taking the upper limb tractor developed by the National Key Laboratory of Wuhan Sports Institute and Haokang without additional drag upper limb tractor as the research object,this paper contrasts and analyzes the method of joint analysis of 10 ordinary college students using two different kinds of upper limb tractor for muscle strength and motion intensity,surface muscle electricity and heart rate synchronization test.The data of the original electromyography and heart rate of the subjects who used two kinds of upper limb tractor were collected and analyzed to analyze the data collected,and to explore the situation of the muscle force and movement intensity of the new generation of active upper limb tractive and no additional drag upper limb traction apparatus,and to design and develop a generation of mass fitness path.Promote the reference.The results showed that the traction movement of the upper limbs of the two kinds of upper extremity tractive devices could effectively move the trapezius,biceps,triceps,brachial radial muscle and ulnar carpal extensor,among which the percentage of work performed by the triceps was the least.At every frequency,the muscle discharge of each muscle in the active upper limb tractor is greater than that of the upper limb tractor without additional resistance source.The percentage of the brachial and radial muscles of the subjects using the active upper limb tractor and the muscle of the biceps increase,and it is more effective for the training of the forearm strength of the trainer.The active upper limb tractor can achieve different motion intensity by changing the frequency of motion,while the heart rate of the upper limb tractor without additional resistance source increases in the three frequency,the heart rate is basically the same level,and the change of motion intensity is not great.
