However, the sport science is a broad field, encompassing disciplines such as biomechanics, motor control and learning, exercise physiology, sports medicine, sport psychology to name a few. Rarely are these disciplines applied in an integrated manner. The purpose of this study was to document the effectiveness of an integrated biomechanics and motor control protocol for improving athlete＇s performance in the high jump. Methods： Four elite high jumpers performed baseline jumps under no^mal conditions and then jumps using a specific external focus of attention cue designed to improve their running posture. Three-dimensional biomeehanical analysis was used to quantify the upright posture throughout the approach as well as horizontal velocity at plant and vertical velocity at takeoff. Results： The results showed that when using the external focus of attention cue, the jumpers were significantly more upright during the approach, had significantly higher horizontal velocities at plant, and generated significantly greater vertical velocities during the takeoff. Conclusion： The results of this study lay the foundation for future work examining how integrating sport science disciplines can improve performance of elite level athletes.展开更多

By affecting the student＇s motivation profile, knowledge of these expectations will have an impact on his progress. The study focuses on two ninth grade classes, where both are presented with a contest, a test and a questionnaire at the beginning and at the end of the cycle. We determine their actual and theoretical performances as well as their initial and final levels of self-determination. Only one class has been given knowledge of their theoretical performance. Then, two variables are analyzed： the ＂learning＂ variable linked to the duration of the cycle, and the ＂pedagogic modality＂ variable, whether the student is aware of his theoretical performance or not. The ANOVA （analysis of variance） tests performed have showed no significant impact of these variables on the performance, but their interaction is an important factor over the perceived progress. This significance is also observable on our subjects self-determination levels, intrinsic motivation and their overall skills. By fostering the teacher＇s perception, knowledge of the theoretical performance does not affect directly the student＇s performance but heightens his intrinsic motivation and favors the progress in his skills.展开更多
