Just a few seemingly unrelated observations from looking through your most recent album posted to facebook:

• Select a shooting position that does not place an open door to the much brighter outdoors in the background. Instead, keep that light behind or about 90° to the side so that instead of fighting that light, you are using it to illuminate your subjects.
• Shoot raw. Adjusting white balance and exposure/contrast after the fact is not destructive with raw files the way it is with JPEG images. For a good example of how well done raw processing can transform a less than ideal action shot, please see this answer to Lots of noise in my hockey pictures. What am I doing wrong?
• Don't try to make the inside of a cave look like the middle of a park at midday sun. The camera doesn't know that everything in the image is not supposed to be medium brightness. Use exposure compensation or manual exposure to set exposure to more accurately reflect the actual conditions under which you are shooting. Let dark corners be dark.
• Don't be afraid to kick the ISO up a little. Your images aren't excessively noisy for use on social media and other web viewing. Noise that is noticeable at 100% pixel peeing magnification on your monitor is much less noticeable when someone is viewing a downsized version on facebook.
• Combining the previous two points will allow you to shorten your exposure times, which will help to reduce the amount of motion blur in many of your images.
• Don't expect every frame to be a masterpiece. Shooting sports/action in low light is challenging! Every frame will not be a "keeper". Learn to let go of the ones that don't work and only post the ones that do.
