Research On Sports Technical Characteristics Of Elite Men’s Marathon Runners Based On Sports Video Processing Technology

Research purposes（1）Research the sports technical characteristics of the popular elite men’s marathon runners,and compare the technical parameters of the international elite men’s marathon runners to find out the technical characteristics between the popular elite men’s marathon runners and the international elite men’s marathon runners Differences and make suggestions.（2）Provide clear and intuitive data references for the mass elite men’s marathon runners,and provide valuable data theoretical references for ordinary marathon runners.（3）Provide valuable reference for experts and scholars in the fields related to the technical characteristics of marathon runners in the future.（4）Encourage marathon runners to apply new scientific methods and scientific methods to develop good exercise postures to achieve the purpose of improving performance,reducing sports injuries,and scientific fitness.Research methodDocument method,expert interview method,video image shooting method,video image analysis method and mathematical statistical analysis method.Research conclusions（1）In terms of stride length,stride frequency,and running speed,the step length and running speed of the popular elite men’s marathon runners are smaller than those of the international master class men’s marathon runners,showing fast and frequent steps.The characteristics of the width,and the difference between different runners.（2）In terms of touchdown time,empty time and ground touchdown ratio,the touchdown time and ground touchdown ratio of popular elite men’s marathon runners are greater than those of international master men’s marathon runners.The air-to-air ratio shows the characteristics of too long touch-to-ground time and too large air-to-ground ratio.（3）In terms of the characteristics of landing methods,the majority of elite men’s marathon runners and international master men’s marathon runners touch the ground with their heels first,and then roll their heels forward to form a full-foot landing.（4）In terms of the joint angle characteristics when the left foot is off the ground and the right foot is on the ground during the running phase,the joint angles of the international master men’s marathon runners are better than those of the mass elite men’s marathon runners.（5）Mass elite men’s marathon runners have significant differences in the angle characteristics of the elbow,shoulder,and hip joints at the moments of landing,cushioning,and stretching of their left and right feet,their core ability is not good,and their torso is unstable when they swing their arms.（6）Sports video processing technology has various forms and powerful functions.It displays the sports technology structure in the most intuitive and scientific form,which can well meet the requirements of marathon runners for technical action analysis,and can provide better scientific guidance effect.
