Trunk/Head
This part of the body is one that coaches really don’t focus on but a player must be able to have good head and trunk alignment. Many great players are not able to maximize their athleticism because they have lazy upperbody alignment while playing the game. Players will lean forward or backward too much and look everywhere but where they should. Though it is mentioned earlier that feet, knees and hips affect balance, but the trunk and head determine a players balance.
First of all we have to look at the trunk. Many players will lean forward or backward in their athletic stance. This takes the center of balance from over the balls of the feet over either the heels or toes. To align the trunk over the balls of the toes a player should have their shoulders in line with their knees and the trunk should be erect. Because the hips will be a little further back, the shoulders in line with the knees will engage the core and will bring the center of gravity over the balls of the feet.
The head is also important in the athletic stance. On offense a player should have their head always to the basket, where as on defense a player should try to keep his/her head between the shoulders of the offensive player. Many players tend to look elsewhere and move their head all over the place while moving around the basketball court. Located in the head are the mechanisms which determine the bodies equilibrium, or balance. This means that the more a players head bobs all over the place, the less balance and control they will have. This is why it is important to have the players align their head with the spine and keep in straight between the shoulders to allow for a player to maintain equilibrium and this will give them good balance. Not to mention it will also help when trying to teach players to always play with their head up on offense and defense to always see the floor.
