The most common method for improving performance in many sports is to improve an athlete’s technique. The application of biomechanics to improve technique may occur in two ways: Teachers and coaches may use their knowledge of mechanics to correct actions of a student or athlete in order to improve the execution of a skill, or a biomechanics researcher may discover a new and more effective technique for performing a sport skill. The second general situation in which biomechanics contributes ...
The normal throwing technique involved more limbs in the throwing action, and you were able to increase the time during which you could exert a force on the ball (and you were probably able to exert a larger average force). What limited your throwing performance with the heavy object—strength (force) or technique (duration of force application)? But in throwing a lighter object, technique (duration of force application) is more important for success, whereas in throwing heavy objects, the ...
The purpose of a qualitative anatomical analysis is to determine the predominant muscular activity during specific phases of a performance and to identify instants when large stresses may occur due to large muscle forces or extremes in joint ranges of motion. The analysis of the elite performance identifies which muscles are involved in performance of the most effective technique, whereas the analysis of the student identifies the muscles used in performing the specific technique. Another ...

Peter Tripp’s experiences are a fairly accurate case study of the consequences of sleep deprivation. A 2005 National Sleep Foundation poll investigated the relationship between sleep and the emotional health of teenagers (National Sleep Foundation, 2005). In a study of 44 college students, where half had 8 hours of sleep and half pulled an “all-nighter,” those without sleep performed statistically worse than those with a full night of sleep.
