Specific Research On Dynamic Plantar Pressure Of 13～15 Years Old Over-weight And Obesity Boys

Use a foot-scan plate insole system to abtain the plantar pressure of the left single-step of 13 to 15 years old boys,who is the students of the junior middle school attached to Northeast Normal University .The purpose is to reveal the impact of different obesity on plantar pressure. To find out the damage of obesity do to the different area of the foot.To provide the reference of particular shoes design for different obesity people, and also to provide consult and contrast for similar research. The main conclusion from research:First, all the plantar force-time curve of the tested boys appeared to be dual-peak ,and the second peak is higher than the second peak. Weight don't influence the gait period of the left single step.Second, weight don't do much contribution to the contact order and leave order of the left foot. The larger the weight is ,the longer the contact time of the middle-foot. Weight can change the present time of every region of max plantar pressure.Third, weight and BMI is very important decision factor of dynamic plantar pressure,load rate and impulse in the boys whose age is between thirteen and fifteen. Weight didn't has much influence in the contribution of the biggest and least plantar pressure.
