The Research About Fitness Reverse Walking And Running On Foot Pressure In Zhe Different Slop And Speed

Reverse walk is opposite direction, with positive walk with a foot of the forepaws ground first again transition to heel legs alternating cyclical movement, two arms natural to and fro, cooperate with even breath. Compared with the positive walk, reverse walk has its own advantages, andtherefore to reverse walk in the research of fitness guidance significance. Due to the positive walk and walk in the touchdown reverse way and exercise patterns of different, two feet on the ground motion mode of force is different, so the ground reaction to foot the force will also vary, the positive walk and reverse walking foot pressure difference, whether to take a lead to positive and negative effect of different gymnastical cause, By reverse walk transition to reverse when running, reverse run appear foot pressure characteristic whether will bring our athletics sports training bring theoretical guidance, When external load namely speed and gradient change and walking and running to reverse the foot pressure change?Using Footscan foot pressure testing system, in order to Beijing sport university graduate school five students for subjects, respectively with speed 1.2 m/s,1.8 m/s in 0°respectively, and 3°on the slope towards walk and reverse walk; With speed 2.5 m/s,3m/s at 0°and 3°slope on the positive run and reverse ran motion, at the same time every name be try acquisition foot pressure data, analyzes different slope and pace of fitness reverse walk under the influence of foot pressure, Different slope and pace of fitness reverse ran under the influence of foot pressure. Meanwhile fixed-point filming 2-d image, have gathered a positive walk, reverse walk, and positive run, run the kinematics of reverse comparison and analysis data, for the same speed when motion positively walk and reverse the difference, the same walking gait velocity positive run and reverse when running gait differences. Through the analysis of the results obtained as follows:1,the fitness reverse affectionately through increasing reverse walk speed and slope can change a foot in different parts of the stress and load increases make body corresponding participate in various organs and joint action of the activity enhanced, thenar impulse decreases, and such ankle and knee, by the impact of the relative reduced, visible load appropriately increase won't give the wallop increase, so, in the fitness reverse when you can add proper difficulty of movement. Using fitness reverse when running pace to increase foot pressure influenced, accordingly, in using reverse run undertakes fitness should choose suitable pace undertakes fitness.2,through the analyses indicate that the foot pressure difference is probably lead to positive and negative to run with different value of exercise and rehabilitation the reason of the effect. Due to reverse when running to face a foot impulse is positive run when small and foot maximum pressure value than positive run to small, reverse run with positive run with different exercise the effect. Reverse ran can enhance the knee extensor muscles, muscle strength, improve human's equilibrium, therefore, fitness reverse running can be extended to exercise.3,reverse running can be applied to the teaching of track and field training, as a sprint, hurdles high support lift heel a practice methods. Reverse when running the increase of slope can achieve better training effect. Suggestions in track and field training enhances the thigh extensor muscles, power, may be appropriately adopting three degrees slope reverse run.
