One additional requirement for fighter pilots is the ability to pass centrifuge training.  Depending on which fighter you are going to fly, you may need to demonstrate that you can properly withstand up to 9 Gs for a sustained period of time.  There is also a FACT (Fighter Aircrew Conditioning Test) that all fighter pilots must complete.  This is strictly a weight lifting test of the major muscle groups.  The weights you are required to lift are based on a percentage of your body weight.  Hope this helps.
