Research On Transformation And Application Of Racewalking For Fitness

Walking and running is to participate in the largest number of fitness programs, research has found that walking is more security than running, but the fitness effect is weaker than running. There are too much injuries associated with running. The running friction and easy to form the iliotibial band syndrome, hamstring injury, patellar pain injury, tibial stress fracture, etc. So if we can have so a kind of sports, it integrated the advantages of walking and running, safe and efficient?So the speed walking in our vision.Research purposes:(1) on the evolution of the iaaf race walking definition and analysis of the definition of speed walking core requirement, the understanding of the broad definition of race walking motion, make the walking motion after renovation is conform to the requirements of the walking motion defined core, at the same time easier to grasp general fitness. (2) of the general population fitness walking, the kinematics of average fitness walking, physiology characteristic analysis, an analysis of the kinetic characteristics of fitness walking and running, to verify that the two research hypotheses,1):race walking for fitness is smaller than the damage possibility of running; 2):fitness race walking benefits than ordinary high.This research mainly use the literature material method and experimental method. Through the literature on the evolution of the iaaf race walking motion definition, summing up the core requirement of speed walking definition, based on the fitness of the reform. After transforming the sports fitness walking, walking for:in the process of walk not visible to the human eye, suspension of support leg knee actions do not make specific demands (can be stretched to knee knees buffer), other techniques (crank arm swing arm, active hip, etc.) is similar to the competitive race walking.In the experiments, subjects complete fitness walking and average fitness walking kinematics, physiology index, complete fitness walking and running the kinematics, dynamics, with the demonstration of the basic principles of fitness fitness walking;Then through 12 weeks of exercise intervention on the effects of fitness walking the actual validation.The results showed that fitness walking at normal speed and rapid movement have a wider range of motion, to be able to get faster speed; In terms of dynamics, fitness walking at normal speed and fast multiple joints of vertical ground reaction force is far less than running, so the possibility of fitness racewalking wounded smaller;On physiological index to 4.8 km/h,5.6 km/h,6.4 km/h speed of three complete unit time fitness walking and average fitness test, fitness racewalking under the same speed on heart rate, oxygen uptake, metabolic equivalent, energy consumption index are higher than average fitness, exercise intensity is greater than the average fitness.After 12 weeks of exercise intervention, fitness racewalking in peak oxygen uptake, vital capacity, weight, waist circumference, hip circumference, balance, have made significant changes in average fitness racewalking group on these indicators have significant positive change, but not, fitness racewalking in these indicators of health effect more than general fitness.The above research results verified the above proposed two hypotheses, that fitness racewalking is a between average fitness walking and running efficiency and security of sports. To promote fitness walking can make fitness means more diversified and fitness effect more efficient.
