▌Abstract
This study tried to explore the performance of entrance angle of free throw (FT) among three different heights by means of smart basketball. This study were conducted by one male player (height=170cm) by means of standing on field (170cm), 10cm stacked wood blocks (180cm) and 20cm stacked wood blocks (190cm). The player had to complete 50 free throw including 170cm, 180cm and 190cm condition. The result revealed that the entrance angle of FT might varied by the player’s height. When the player’s height is 170cm, the entrance angle was located between 42 degree and 48 degree. In the 180cm condition, the entrance angle of FT was located these two intervals, including 0-37degree and 42-48 degree. Once the player’s height was 190cm, the entrance angle of FT is located between 42 degree and 48 degree. According to one-way ANOVA analysis, it showed that the difference of average entrance angle is significant among three different players’ height. Furthermore, this study also found that the 170cm condition of entrance angle is higher than the 180cm condition significantly in the interval of 42-48 degree. The entrance angle of FT might relate to three throw percentage (FTP). By means of smart basketball, it can provides a real time data feedback the players. These data will assist basketball player to modify or adjust individual’s free throw processing. Moreover, with successive practice to enhance the stability and accuracy, furthermore improves individual’s basketball FTP.
