Objective and self-perceived performance adequacies in collegiate basketball players.

A self-perceived and objective measure of performance adequacy were assessed in 11 male collegiate basketball players. Minor significant relationships between the rating methods were found in only four players. The two procedures indicated that they were primarily measuring two different structures. The conclusion was made that an athlete's perception of his/her performance adequacy was likely to be different to that indicated by an objective performance measure or a coach's perceptions. Implications for coaching and future research were indicated.

[Decision making by intercollegiate basketball players].

The results of several studies suggest that in an event incertitude situation, elite athletes can select the appropriate response faster than the novice. There are at least two possibilities to explain such a difference. First, it could be that the elite athlete has more facility to reduce the amount of information he/she is confronted with, that is he/she is able to identify more easily certain sequences and patterns in the play of his/her opponents. Secondly, it is possible that the athlete uses the available information in a different manner. The purpose of this study was to verify the second hypothesis. 10 subjects (5 novices and 4 intercollegiate basketball players) were submitted to a choice time task where the required response was a total body displacement over 2 meters. The results suggest that elite athletes use their knowledge of probability of events in the same way as the novice subjects.

The relationship between women's basketball performance and will to win.

An analysis of the determinants of athletic performance indicated that "desire" or "Will to Win" was an important factor while an interactionist approach to personality suggested that differences in "Will to Win" might be expected both for different sports and at different levels of performance within a sport. The purpose of this investigation was to determine the relationship between "Will to Win" and performance in an eight-team women's basketball tournament. Players completed a 14-item "Will to Win" questionnaire. Team and individual scores were compared with various indices of performance. Results revealed that between two competing teams, the game was more likely to be won by the team with the higher average "Will to Win". The correlation between the mean "Will to Win" score for a team and its position of finish in a tournament was not significant. An ANOVA and Newman-Keuls comparisons revealed that the last place team had to "Will to Win" score that was significantly lower than five of the seven other competing teams. Data obtained on individual players indicated a significant but low correlation between "Will to Win" and the mean number of points scored by a player.

An en bloc avulsion fracture of tibial tuberosity and Gerdy's tubercle in an adolescent basketball player: a case report.

We report a case of en bloc avulsion fracture of tibial tuberosity and Gerdy's tubercle, which has never been reported. A 14-year-old boy suffered from an acute pain in his left knee during running just before a jump. Simple radiographs showed an avulsion of the tibial tuberosity. On CT scans, the fractured fragment was attached not only to patellar tendon but also to iliotibial band (ITB) via Gerdy's tubercle. MRI evaluation revealed no intra-articular associated pathology. Open reduction and internal fixation with three cannulated screws were performed under lateral parapatellar approach to expose both the tibial tuberosity with patellar tendon and Gerdy's tubercle with ITB. At postoperative 1 year, he could walk, run, squat, and complained of no difficulty in activities on daily living with full range-of-motion of the knee. Radiographs showed well-healed fracture in situ. Gradually, he returned to sports activity. We believe that the injury was caused by the dynamic pull of quadriceps muscle via patellar tendon onto tibial tuberosity and the mostly static pull of ITB onto Gerdy's tubercle, both of which took a part in the fracture of the anterolateral portion of the unfused epiphysis of proximal tibia. The pes anserinus attaching on the anteromedial metaphysis of proximal tibia might exert the opposing deforming force. Preoperative planning including the determination of the extent of fracture and recognition of concomitant injury is a prerequisite for appropriate treatment.

The influence of basketball shoes with increased ankle support on shock attenuation and performance in running and jumping.

The aim of this study was to assess the influence of footwear with increased ankle support on ankle kinematics and on impact loads during landing from a vertical jump using high-speed cinematography, dynamometry and accelerometry in a series of tests in which a rebound action was simulated. To analyse the effect of this increased support on motor performance, two performance tests were designed: a vertical jump test and an obstacle course running test. Two prototype shoes with identical soles but different uppers were used. The first was designed to provide greater ankle support, with such features as a high top, heel counters and a rearfoot lacing system. The second prototype was a less supporting shoe, with low top and no heel counter or any other feature for support. In the shock attenuation test, the use of high-support shoes resulted in higher forefoot impact forces and higher shock transmission to the head, but showed lower shock transmission to the tibia. The use of high support shoes resulted in lower ranges of eversion and higher ranges of inversion of the ankle on landing. In the motor performance tests, the high-support shoes reduced the height jumped and increased the time to complete the running course relative to the low-support shoes. We conclude that increased ankle support reduces ankle eversion range but increases shock transmission, and reduces both jumping and running performance.
