Gansu Province Young People Women's Heel-to-toe Walking Race Athlete Technology Movement Kinematics Research

Gansu Province is situated at the Asian plateau region, the suitable geographical environmentcauses the endurance project to become Gansu Province's traditional superiority project. TheGansu provincially established unabridged book province's actual situation, in line with thecompetitive power and the frugal principle, tries to make the brand project and the project group.Since the 1990s, Gansu Province's heel-to-toe walking race athlete in international, the domestictrack and field big game has made the outstanding progress, but compares with the men's heel-totoewalking race movement, Gansu Province's women's heel-to-toe walking race movementactually has not obtained the very good development. Therefore, it is necessary to strengthen thewomen's heel-to-toe walking race movement the theoretical science research, specially aims at theyoung people women's heel-to-toe walking race athlete's technical movement to carry on thediagnosis, provides the theory support for the Gansu Province women's heel-to-toe walking racemovement's echelon development as well as the scientific training. The heel-to-toe walking racemovement is listed as the technical endurance project, in the contest rule has to its technical normsand the referee method the strict stipulation. Although the home studies to the heel-to-toe walkingrace the direction are many, but limits to the technical research to the technical movement principlediscussion, lacks to the heel-to-toe walking race technology system research. Specially utilizes thethree dimensional photograph method to carry on the quantitative analysis aspect to the heel-to-toewalking race movement technology the research to be few in number, but uses the threedimensional photograph method the research which carries on to the Gansu Province heel-to-toewalking race movement technology not to see until now. In addition, to the heel-to-toe walkingrace movement's research, the object of study concentrates massively in our country top athlete,lacks to the young people heel-to-toe walking race athlete technology movement research.This research takes the object of study by the Gansu Province physical culture work crew's 6young people women's heel-to-toe walking race athletes, through literature collection massivecorrelation data and the empirical datum and so on material law, expert interview law, high speedphotograph photography law, carries on the analysis on the way through the movement imageanalysis law and the mathematical method of average to the athlete straight road heel-to-toewalking race technology movement parameter, unifies the athlete body shape target, the physicalquality target, and the training arrangement, carries on the diagnosis overall to the athletetechnology movement, discovers subject matter which and reason in the athlete technology exists,proposes the corresponding improvement program.The main conclusion is as follows:(1) the Gansu Province young people women's heel-to-toe walking race athlete trains the agelimit to be short (equally is about 3.5 years), the movement technology is not mature, is stable,lacks to the heel-to-toe walking race technology thorough understanding and the understanding.(2) the Gansu Province young people women's heel-to-toe walking race athlete's bodily shapetarget meets the heel-to-toe walking race athlete's special requirement basically, but the muscledensity is small under the same level height condition.(3) the Gansu Province young people women's heel-to-toe walking race athlete's, degree of tiltis suitable, torso angle change not very obvious, will not assign a penalty to the referee soarstechnical foul to have the very tremendous influence.(4) the Gansu Province young people women's heel-to-toe walking race athlete's support legin is well-grounded the phenomenon which the instantaneous knee joint has cannot unbend fully, but the knee joint angle still belonged to the reasonable scope, and the liftoff instant the knee anglepossibly slightly surpasses some home outstanding women's heel-to-toe walking race athlete's level.(5) the Gansu Province young people women's heel-to-toe walking race athlete delivers thehip movement not to be full, possibly is causes its length of stride to be short, the shoulder hipangle of torsion small major technique reason.(6) Gansu Province young people women's heel-to-toe walking race athlete, the pedal angleoversized possibly is causes the Gansu Province young people women's heel-to-toe walking raceathlete soaring time to be excessively long, the bodily center of gravity vertical displacementoversized major technique reason. But the Gansu Province young people women's heel-to-toewalking race athlete lower limb explosive force is bad, the malleolus, the foot joint and the thurlpedal extends ability weakly is also causes after that the pedal angle to be oversized, the supportleg support time is excessively long, the pace to be slow, shoulder hip angle of torsion smallphysical quality aspect primary cause.(7) the Gansu Province young people women's heel-to-toe walking race athlete malleolus jointback bends ability to be weak, possibly is causes it to be well-grounded the instantaneous soleelevation angle too small physical quality aspect primary cause.
