Hi,
Suggestions . . .
1. See if you can get access to the indoor facility before or after normal operations are done, also arranging for your models/subjects to come at these times to do a static photo shoot.
2. Plan the shots you want to shoot, then pose your subjects so they are not moving at all. Set up your camera on the course so you can get shots of the subjects that show their frontal features. This will assure interesting shots and angles, and allow you to really concentrate on composition elements within your frame.
3. Always use a tripod.
Good luck
