The following comes Rahel Smith via Crieghton Burns:
Body language can be described as how one uses gestures and body movements to communicate. Body language can give insight into what an individual may be thinking or feeling. On a basketball court players frequently send messages to coaches, teammates, referees, opponents and crowds.
Below are four ways to exhibit positive body language on the court:
1. Look your coaches in the eye when receiving instruction. nod your head to show them that you are paying attention.
2. When your teammate makes a bad play, keep your head up, give them an encouraging look and keep playing hard. The selfish, immature thing to do would be to whine, roll the eyes or pout at a team mate.
3. Look enthused and energetic in practice and game situations even when you don't feel that way.
4. If your team should happen to be losing in a game, keep a stone face. Show a confident demeanor and don't let opponents see you rattled.
