Simple answer for me is no, I really don't make any in camera changes other than shutter, aperture and ISO. I haven't really noticed any issue with the white balance which I normally have set to Auto as I haven't felt the need to change it. I have shot in a number of gyms that have lights that cycle so an image that is captured at one point in the cycle has a different WB than one shot at other points in the cycle. As near as I have been able to tell from thousands of images in those gyms, the body gets it correct, but it does not change it during a group of images. As an example, the lighting cycles fast enough that your eye doesn't notice it. Without going through and confirming, my experience is that when shooting a group of images in continuous mode, the camera does not adjust the WB with the shutter release pressed so you can see the lighting cycle on some images which won't have the correct WB. That is generally fairly easy to correct in post processing. In general, the tint of the image varies from good WB and on either side depending on where the shutter fired during the light cycle. Some gyms didn't have that issue (depended on the lighting) and some it was more bothersome than others...
I never felt a need to shoot a paper or whatever to fine tune since most of what I deal with has some white that I can use to work with. Either the home or the visiting team is wearing primarily white uniforms (varies with the sport I'm shooting) so no real need to "bring my own". I also prefer as natural a look as I can get on most of my images and I tend to process those images fairly soon after shooting...maybe it is me but I try to adjust things to what I saw than to some specific level of white or whatever. I'm guessing you could probably see that in some of the images I've posted. Another example:
The white balance on that shot is "As Shot" in LightRoom and Auto in camera. There are several of "shades of white" in the image above. Note that other than slight cropping, there are NO edits to this image. The white on the front of the helmet is different than the white on the chin strap and the white of the jersey is different from both as well. The white on the jersey has a variety of shades from white to dark gray depending on the light that is hitting it. Just because I felt it an interesting test, I converted to B&W in LightRoom, with no other changes...
While the jersey looks quite white to me in the color image and a bit gray to me in the B&W, it looks correct based on what I saw on the field. On another forum I have seen people suggest the white balance was off on similar images. Who knows, someone here may tell me that for the image above, but whether or not it is "correct" to me is based on what I saw and not some specific measurement. Hope that helps!
