Meddelande: <blockquote data-quote="domino" data-source="post: 848623" data-attributes="member: 112497">Isokinetic and isometric assessment bear little or no resemblance to the accelerative/deccelerative motion demonstrated in muscles during resistance training and sporting performance. Isometric/isokinetic dynamometry is generally not available to most athletes that train for power. Power is the product of force and velocity. Power should not be confused with rate of force development, explosive strength (maximum force/ time to achieve maximum force), and impulse. Not clear which characteristic predicts performance the best. Leg power does not generally correlate well with jump height. Impulse, rate of force development or explosive strength may better predict performance than power. It is important to remember that just because a strength or power attribute predicts performance well, training the attribute will not automatically improve performance. The challenge for sport scientist is to develop test batteries that provide insight information of the key mechanisms that make up the performance. Suggests that a regression approach instead of correlation analyses should be used to develop models that predict performance. Will increase systematic (Cronin & Sleivert, 2005)</blockquote>
