Training for improved vertical jump.
Explosive power is a requirement for success in many athletic skills.
This is not to be confused with the common concept of strength. Strength may be talked of frequently and trained commonly but the way it is practiced is not good for many sports. A typical explosive strength action is the vertical jump. Dynamic strength is defined as the maximal ability of a muscle to exert force or torque at a specified velocity . However, tests of 1 RM strength are of limited practical value because this specific type of strength is employed in only a few athletic endeavors, such as power lifting.
