This study is to analyze the ground surface resistance according to the positions of the feet on the starting block in 100 meter race using short distance starting block precision sensor. The followings are the results of the study. First, in starting response time, B(type) showed faster response to the starting signal in both directions such as left and right. Second, in the maximum horizontal strength delivered as forwarding power, B(type) showed bigger strength in both direction such as Left (0.02;BW) and Right (0.16;BW). Relatively, in the left side both types (A and B) showed stronger resistance. Third, in the maximum vertical strength value, in both directions B(type) showed bigger value as Left (0.24;BW) and Right (0.14;BW). ). Relatively, both types (A and B) showed larger maximum vertical resistance in the right side. Fourth, in the maximum resistance, B(type) showed bigger values as left (0.13;BW) and right (0.15;BW). Relatively, both types (A and B) showed larger maximum resistance in the left side. The strength added at the starting movement of the player is delivered to the pedal as vertical strength (Fr), which delivers the power to the whole structure of the pedal and the connection hook of the support and cause Horizontal Resistance (Fh) and Vertical Resistance (Fn). To make a long story short, B (type) that place the whole soles of the feet on the starting block pad has better starting power (propelling power) than A(type) which place the feet on the surface of the ground and on the block pad at the same time. It is supposed that if you have larger starting power, you can get initial horizontal speed more quickly. Eventually, it is guessed that the posture or method to make forwarding power bigger will bring the improvement of the initial record.
