[Music] when people think of the American development model or ADM they often think only of cross-ice games for Mike while Mike development is one critical element the ADM has many pieces which have not been explained completely to the hockey community in this special episode USA hockey's Roger Grillo shares how the ADM windows of trainability concepts and it's training implications means so much more for athletes in all stages of development really far beyond a smaller ice surface for my team the American develop model basically is an opportunity to really stress the need for age appropriate environments for our kids to me the most important message we send is the windows of train ability for parents athletes and coaches to grasp the windows of train ability and understand where those athletes are absolutely critical that's the sports science that everything we do is based on it's all the age appropriate training for example eight-and-under they're in their suppleness window trainability suppleness window is basically your athleticism so if I'm coaching a group of eight hundred kids I just want to build a really strong base of athleticism so that's bad athlete when they do have to reach back at an older age to a base of athleticism it's their the most important thing at eight and under it's a talking about building a strong base of athleticism it's making sure that when I'm on the ice my worth the rest ratio is one to one I'm going to every other time that I'm doing stuff in small spaces I'm doing a lot of jumping spinning turning getting up off the ice short distance change a direction not worrying about anything other than that part of their athleticism and staying as far away as possible as I can from positional play and team play and that's why for us the cross ice game is so critical because not only are those eight-and-under kids in their athleticism window they're also in their first speed window and the first speed window is really the first five to ten feet it's the quick change of direction it's the quick burst it's that explosive start and so putting them in a smaller space where they're forced to do that a lot just helps their development happen that much in the office fees the best thing a parent can do is either have their child involved in some type of programming where they're doing some of that tumbling and agility and coordination and balance work or the hockey association develops a curriculum and this is what we're encouraging strongly they develop a curriculum within their hockey association where those kids once or twice a week when they come to the rink for practice there's an extra 30-minute the 40-minute session that works on that for the athletes our 1200 players are sports and peelings they're in their skill acquisition window absolutely critical that we focus on catches and repetitions that our practices are based on the individual athletes need in skating passing stick handling shooting decision-making so that when they are put into a team and winning becomes highly important at the older ages they have the skills to be successful so the other critical windows the Train ability as kids get older there's the second speed window which is now a little bit more north-south a little bit more open space you've got your strength window which happens a little bit later and each kids a little bit different based on their physical and skeletal growth to us the two most important windows are the athleticism piece from about five to about nine and in that skill acquisition window which starts at about eight to about thirteen those two windows to us are the base of what's going to happen later on when an athlete gets to about 13 14 15 and everybody's a little different the responsibility now transfers to the athlete because the windows that they're in there are really stuff they got to do on their own it's getting stronger it's getting in better shape it's the sacrifices I have to make with nutrition and sleep habits and all the other stuff it takes to kind of take that next step as an athlete it's really now what they do away from the rink that's so critical for their next step as an athlete whereas when they're younger it's all the stuff that's happening in the rink so we've got to make sure that we were as the adults the coaches the administrators the parents we're putting them in the right environment so they can have success when it is their turn to take the responsibility so how we handle the young athlete in a lot of cases is going to determine the success of the old I'm Roger Grillo from USA Hockey you gotta love Connecticut hockey [Music] [Laughter]
