My shutter speed settings for shooting sports are 1/4000 versus for weddings, 1/125, or 1/250.

If auto ISO sensitivity control is enabled, ISO sensitivity will automatically be adjusted for optimal exposure at the selected shutter speed and aperture. In addition, you can choose an upper limit for auto ISO sensitivity control to prevent ISO sensitivity from being raised too high.
Use the Shooting Menu Bank to save the settings you use for sports in one of the four presets you can even rename. Here are my four banks:
