Using Nikkor or Canon glass, AF in rapid situations will be less than advantageous The mechanics involve a lens motor combined with contrast detection (video) Live View. If I am wrong, someone will correct me.
Sony and Panasonic use chip based focus recognition and are able to resolve follow motion more quickly but these are companies which know motion capture from the video engineering side.
N and C aren't to blame because they were, until the D90 arrived, primarily camera centric where stills are the norm.
The best approach for using Nikon glass is shooting manually.
With a follow focus or without it requires excellent skills as Nikon lenses are not built as cinema glass with large wide throw rings and definite stop points when racked.
There are exceptions, older and some current primes, perhaps zooms like the 80-200 f/2.8 which doesn't rotate to infinity and are around $800.
Others may have different advice.
Quick pans, shift in subject's range, movement back and forth, movement of OOF subjects behind the in focus subject, will all (potentially) introduce softness and jell-o especially when transcoded from 1080 to a compression level acceptable for web services.
I had this issue when a label wanted to web publish.
The compression scheme used by the host was so low as to make the film unwatchable. We are negotiating a higher bit rate at this time otherwise, I won't release it for sale on their portal.
Now that is not saying one cannot grab usable footage doing things by hand.
I have considered using face recognition to try and catch Dragonflys over the pool, but fast capture will take practice.
Another way, is shoot two cameras, one static wide shot to cut in or out from while the lens motor is trying to resolve.
Roger and Peter may have much better advice as they combine efforts to shoot equine events, so stay tuned.
The V1 does a better job of focusing on moving objects than other Nikons, especially with the Power Zoom lens. Using FullTime AutoFocus is possible.
I always need to use a TriPod with the D800, because I do not have a big stablilizer rig. I shoot in Manual Mode and AF-C but sometimes use the AF-ON button as I am not good at manually focusing my lens. A high resolution external Monitor helps.
Pete shoots Soccer with his V2 and D800. He has a lot more practice shooting sports. I normally only do the Sunday Morning Service.

I did this for my Neice and would again. By the way she won the Woodside Equestrian Grand Prix Event.
