103. @PedroE_Alcaraz pedro.e.alcaraz @PedroE_Alcaraz Some authors justify that YES… 1. ... Because there is a high demand for horizontal force in the sprint; 2. ... Because the maximum power production with these methods is given with high loads; 3. ... Because there is a high activation of the biceps femoris and serves as preventive training; 4. ...

130. palcaraz@ucam.edu @PedroE_Alcaraz pedro.e.alcaraz - Applied Force and mechanical power are determinants for performance in force-velocity disciplines. - There is an optimal load where power is maximized. - The training has an effect on the force-velocity curve and therefore on the power. - Care with the use of science. Always broad vision. - The maximum power output will be dependent on the exercise, level of the athlete or muscle group involved. - For the improvement of the maximum power the principle of specificity must be considered. - Resisted methods, complex training, etc. are very suitable ways to improve power.
