I couldn't get the focus to function well in several modes. I don't know if these are individual camera problems or weaknesses in the design. There were multiple issues I couldn't resolve. Sent it back
This kind of photography is difficult for even very sophisticated DSLRs as there just isn't enough light in a gym to capture fast action unless you invest thousands in an ultra fast lens. A point & shoot isn't up to the task. Try using a higher ISO - 1600 or 3200. Also try prefocusing on a certain spot & anticipating the action that will come into that spot. That way your camera will have time to focus. That takes some practice & luck, though. I wonder if the movie mode would be better to use. You could print an image from the movie (see p. 183 in the manual or your photo editing software's help). Might be sharper, though dark.
