Abstract

INTRODUCTION AND METHODS The method of sports biomechanics and a high speed cinecamera (100fps) were used to analyze and study the full run technique of Man's during the time when she broke 10,000 meters world record (30: 18:66) at the National Games of China in 1994. RESULTS The results showed that her speed during the first 7,000 meters was around 5.6 m/s and later on Man continued to accelerate until her speed reached around 6.2d.s and when sprinting, her speed was 6.30rnJs. Her stride frequency during the full run was steady and kept up around 3.6 strides per second. Her stride length was about, 1.55 m during the first 7,000 m and was 1.68 m and 1.75 m during acceleration and sprinting respectively. Man's stride structure was quite reasonable. The amplitude of her legs was wide and her swinging leg changed over to supporting leg with little horizontal stopping. Man's strong leg drive gave a better forward momentum (the angle of Man's leg drive was about 64 degrees), and the time of her stride in air was short (0.126 s). The undulating movement of her center of gravity was small (only 6.8 cm). During Man's acceleration and sprinting after the first 7,000 m, she greatly improved the amplitude of movement and velocity so as to create technical conditions for effective acceleration.
