Speed Roller Skating Technology And Traditional Technology Of Double-push Plantar Pressure Transmission Characteristics Of Comparative Analysis

Speed roller skating traditional technology and double-push technique for straightwith taxi technology, because skating motion is provided by the speed skating evolved,so the traditional glide technology refers to the speed skating technology with similarglide technology; While double-push technique is by americans Chad Hedrick inventedan embodiment of roller skating movement characteristics of straight glide technology.At present, double-push technique has become a mature speed roller skating straighttaxiing technology, by national player widely adopted by some skating sportspowerhouses has of double-push technique were further research. Our players using theratio of double-push technique is increasing year by year, but because of double-pushtechnique research few, and stay in qualitative stage, so responsible for most coachesand athletes of double-push technique profound understanding of, of double-pushtechnique action principle understanding inaccurate, become our country sports levelwith international skating skating level produce larger gap one reason. Based on jilinsports college courtyard of northeast normal university courtyard accobatic gymnasticaccobatic gymnastic and six NanDuiYuan for experimental object, adopting BelgiumFootscan company produces the foot pressure plate system (Footscan7USB2gaitsystem) acquisition foot kinetics parameters for obtained data by using FootscanSPSS10.0SOFTWARE7.00, Excel SOFTWARE and DPS SOFTWARE, data statisticsand analysis.Results:(1) Traditional technology and a single step, used to a taxi ergometer relativelyshort time, deng to force strong, powerful explosive force; chirp Double-push techniquea single step pedal to twice, used over a long period of time, twice to keep your taxiingergometer. Save fitness favorable.(2) The traditional technology department and foot forsufficient with central first landing transition into the all-sufficient, pedal to end forsufficient with area first carried from the ground area before finally carried from thefoot ground, so sufficient with district to less than full strength ergometer area before.Double-push technique for foot area before the lateral first touchdown, transition to thefoot central to the all-sufficient. The traditional technology department and feet withfoot touchdown security support central first glide smoothly, and double-push techniquefloat foot touchdown reseal the stirrup for the first time, as the first pedal to need tocomplete the blade ergometer, so sufficient area before the lateral first landing directlyinto pedal to stage without rest waste action.(3) Traditional technology and foot themain area that transmit strength for foot before CeZu central area, foot inside the medialpressure value, sufficient lateral pressure value high low; Double-push technique firstpedal with sufficient with area as the main area, the second send force to gawk andtraditional techniques for foot central consistent, medial and feet area before the inside.
