Research On Feet Touch The Ground Methods Inlong-distance Race Of The Aged Enthusiast In Changchun City

As China gradually aging society processes, and continuous improvement ofpeople ’s living standards, the health of the elderly are under increasing attention.More and more of the elderly into the fitness team, which, as a typical aerobicsmarathon, with its comprehensive fitness effect, become the first choice of manypeople.Among the many athletic events, there is a foot of ground in the process, it isnot only a necessary step, it is a direct source of power athletes. However, fordifferent sports, about a foot landing approach is different. For a long time,academics for sprinting, walking, long jump feet touch the ground, such as projectsundertaken extensive research methods to obtain scientific training methods, but inthe long run research projects in this area are not many. Marathon is a test of speedand endurance sports, not only for the athletes have higher physical demands, butalso need the right training methods, right foot forward to ways to improveperformance while reducing harm to the body. To fitness for the primary purpose forthe elderly, the latter is particularly important.In this paper, the use of high-speed cameras, three-dimensional dynamometer,EMG sensors and biomechanics, anatomy principle, through access to literature,visited the survey instrument experimental analysis and mathematical statistics,research methods, Changchun City,20parks (7), schools (9), Stadium (2) carried102long-distance running and fitness in the elderly as the research object, their feet touchthe ground during the movement embodied, biology, kinetics for statistical analysis.Identify the relationship between these characteristics and body injury tibia fatigueperiod, to provide scientific and effective guidance to the health of the elderlylong-distance running.
