Advantages
The
ability to jump and hang in the air is required for sports
such as basketball, volleyball, track & field and football
and is one of few athletic skills that can instantly raise an athletes
performance to another level. Jumping power is
generated largely by the lower body muscles while the core
and upper body muscle strength support the vertical lift
driving force. The dForce Trainer jumping
systems develops the fast twitch muscles for the vertical jump.
