摘要:The purposes of the current study were: a) to compare the percentage of success of professional basketball athlete’s in a same task (free-throw), executed in different environments (training vs. competition/matches); b) to verify if the percentage of the athletes success differ between themselves in the situations of training and competition. Participated five men, average age of 28,2 years (± 6,06), of a first division club of the National Championship. The McNemar’s test showed that two athletes had gotten inferior performance (p ≤ 0,05) during the training and the KrusKal-Wallis that the athletes had not differed between themselves in the percentage of success. Ability to control the anxiety and the technical level of the athlete’s can be related with these results.
