Abstract
The present study examined the influence of shot training with a ring that narrowed the diameter of the basket during the performance of a free throw by 12 college basketball players. The training group attempted 30 shots in one session 5 times per week for 4 weeks. The number of failed attempts was decreased in this group compared with a control group who shot at a regular basket. Moreover, differences in projection angles were decreased by training. It was suggested that the free throw training at a ring with a narrowed diameter helps the player to shoot more into the center of the ring with higher repeatability.
