Abstract
The purposes of this study were to measure students' game performances and game aspects in basketball during elementary school physical education classes, using 3-dimensional photography analysis with the DLT method. Five physical education classes at two elementary schools (X elementary school and Y elementary school) were taken as the object of investigation in this study. The main results were as follows: 1) the average and standard deviation of the movement distance of all the elementary school children was 397.7±58.5m in a 5-minute game, and the average and standard deviation of the fastest movement speed was 4.70±0.43m/s; 2) the movement speed of all the elementary school children was less than 20% Max-movement- speed (it was moving at the rate of "walking") for about 50% of the game, and they sprinted (more than 80% Max-movement-speed) and stood for about 1% of the game respectively; 3) the game aspect was a three-step model changing between the offense-defense assignment type, the straight line and dumpling type, and the wide area and dumpling type.
