Every sports photographer is guilty of “chimping”. If you’re unfamiliar with the term, this definition will clear everything up.
Essentially, chimping is when you check every photo you take on the LCD. Why is this bad? It takes your eye off the action and puts it on the camera. This is bad for two reasons: (1) you can get hurt more easily, and (2) you may miss a good shot.
When you chimp, you take your eyes off the field and the action. If you’re shooting football, you can easily be run over on the sideline when not paying attention.
While reviewing your pictures is ok, there is a time and a place to do so. In sports, after the shutter clicks there’s no second chance. You must move on to the next play.
