ABSTRACT

Drop Height(cm) 15 Mean 30 Mean 45 Mean Height Jumped(mm)

Data in Table 2 demonstrate acceptable jump heights. Average contact times were close to or greater than 250 ms.

While the prevention of training injury was the basic reason for the use of RSI monitoring there was no comparative data from previous seasons with which to compare injury rates. In this pre-season period there were no player injuries that could be attributed to plyometric activity during conditioning.
