Hello Ali! How old are those players and at what level do they compete? You could start by taking a look at the International Olympic Committee consensus statement on youth athletic development available at
Bergeron MF, Mountjoy M, Armstrong N, et al. Onternational Olympic Committee consensus statement on youth athletic development Br J Sports Med 2015;49:843–851.
Hey Ali; Just a few quick thoughts. Depending on the age of your athletes I would be very slow to do any polymeric work with them. I have been testing a theory on my 15 year old son. He is in the process of going through puberty and with that there is an extra amount of testosterone going through his body, and we want to use that to our advantage and build a solid strength base. He is working out but I did not let him do any plyo work. He fought it a little since he wanted to do what his friends are doing. I asked him to just wait a little and trust that all the jumping he was doing in practice was enough. A year later many of his friends are battling over-use injuries because their bodies were not ready for all the jumping. His is getting very strong and may be in a position to do it down the road. But even with our university athletes I do not feel the need to do much plyometric work. They are so hard on the body and I have found that there are many other forms of lifting that can prepare the body for the power they are going to need for the sport. All the best.
