The purpose of this study is to examine the relationship between anxiety and free throw performance in basketball games played by the four college men's basketball teams during 1998 and 1999 in Taiwan. To determine if anxiety is realted to the players' performance, forty-eight players completed the Sport Competition Anxiety Test (SCAT) and their free throw shooting percentage in the game were also recorded. The results indicated that there was no significant relationship between percentage of free throw shooting and anxiety of high expectation to win the game while the somatic anxiety was highly correlated to percentage of free throw shooting. The reason is that players with high somatic anxiety were not easy to concentrate in basketball games. The results also showed that the relationship between self-confidence and percentage of free throw shooting was not as high as we expected.
