Indoor photography requires a DSLR with a good ISO capability and you also need fast lenses, i.e. f2.8, f2, f1,8 or faster

You've sort of challenging the camera outside it's comfort zone.
Is this indoors or outside.
P&S and Bridge camera's tend to have great problems with images taken of moving subjects, especially if indoors.
The time it takes to focus the subject then take the image ain't lightning quick, and you subject has moved, hence blurred images. Unfortunately action photography is more in the realms of a DSLR with a fast lens than a bridge camera or P&S.
You could increase the ISO setting on your camera, this will allow more flexibility with the shutter speed, but it also introduces noise. Can you manually set the shutter speed, have a play with those.
Agree with Pete. Low light action is the most challenging situation of all. To make a proper job of it you need high end kit. Think a grand and upwards, plus a fair amount of knowledge and skill.
A canon 50mm f/1.8 and a 1000D isn't going to cost a grand
I know thats not pro kit but it will do low light alright. I was gobsmacked that I could take handheld, non blurred photos of my bedroom last night (which is really poorly lit) on ISO 400, that were actually exposed brighter than the room was, with just a 450D and a 50mm f/1.8
