Just Jump System
The Just Jump system is an excellent entry level jump mat that is being used extensively in Performance Sport.
Hand held computer displays height and hang time for one jump, ground contact time for one jump and average height and flight time for four jumps.
It can also be used for sprint time – the system is started by an audible sound and the subject runs to the mat and the timer is stopped when the athlete touches the mat.
Computes foot quickness (shuttle runs and dashes) and explosive leg power rating. Records 60 jumps, then averages heights, contact times and leg power for first and last 15 jumps, in addition to a fatigue factor rating. (PLYOMETRIC version only)
