Canon 50d I have a canon ef-s 55-250 IS lens

Question

I have camera set in ISO @3200, dial at highest +2, set in TV mode in white fluorescent light, need to go higher with shutter in TV mode to get action shots, and in a gymnasium basketball and in a sports dome lacrosse pix come out way to dark, if I go lower shutter speed pix are blurry! I need more light. Is there any way to get more light with equipment I have?????? Ive heard to put camera in ISO H1 but don't know how or if this would solve the problem!! Thank u

THere are a couple of threads in the past couple of days that discuss this same topic, I'd recommend searching for action night photography. 
In summary, what you're trying to do is a very technology dependent type of photography, and it's why sports photogs spend 10s of thousands of dollars on gear.  If you're already at your max ISO, and you can't use a slower shutter speed, and can't use flash, then there isn't any more you can do - with the equipment you have.  However, a couple things to note:
You said that you set it at +2?  Is that exposure compensation?   If that's the case, you can get two free stops of light right there, because you're trying to over expose two stops, which means the shutter is staying open 4 times as long as it needs to.  Dial it back down to 0.  If you actually meant -2, and the photos are darker than you want, then there's not much you can do.
Don't bother using ISO H1, if there even is one on your camera.  It doesn't do anything you couldn't do yourself in post, yet have control over it.  Are you shooting RAW?  If not, I recommend shooting RAW.  This will allow you to boost the exposure slightly in post.  At that high ISO you're not going to get much from it, but it's better than nothing. You can even expose slightly under (as mentioned above) to raise your shutter speeds and then raise the exposure in post, but this will increase the amount of noise.
As far as equipment fixes:  The cheapest is probably to get a faster lens (one with a wider max aperture).  But good long lenses are very expensive.  The 200mm 2.8 would get you 2 stops more light, but you'd lose some reach.  It's also a $700 lens, but you can probably find used ones for cheaper.
The other choice is a better camera.  But to really make a sizable leap via this route you'd want to get a full frame, and then you'd need new lenses for it, so we're talking a lot of cash.  Upgrading a little, to something like a 70D would give you higher ISO options, but only makes for a small increase in high ISO performance.  So the results can be noisy if you max out ISO...  but it doesn't seem to be bothering you on the 50D.
