I have been working with a friend of mine's daughter as she prepares for her college season as a DS/L. I have done a lot of reading about serve MPH in the college women's game and have come up with some pretty interesting data points of my own, with the help of a radar gun.
We set the release point of the serving machine at approx. 7.5 feet, and we set the machine 4 feet behind the serve line. I know there are players that release above this on a jump serve, but here is what I found:
A true float serve with no spin cannot exceed 33 MPH or it will be out. They really need to be in the 31-32 MPH range to be comfortably in.
To get faster MPH than that, the ball will have to have top spin on it, and 38 MPH is as fast as it can go and still be in.
You can set the machine back another 3 feet, 7 feet total from the serve line, and a float serve can reach 36 MPH. Above that, it is out.
Not sure if any of this is helpful. But you hear all sorts of crazy stuff about fast serves. Certainly it's possible in the women's game to exceed 40 MPH, but that's going to be a tall athlete that is launching from 8.5 to 9 feet. There probably aren't many in the country that can do this serve after serve.

Just attended attended junior club team tryouts where they speed gun every playrs jump float top one observed by me was 39mph. But i am unaware if that was top mph. |

Just attended attended junior club team tryouts where they speed gun every playrs jump float top one observed by me was 39mph. But i am unaware if that was top mph. To get above 33 mph, we had to back up 7 feet from the serve line. We got it to 36 MPH but some of those were still going out. There's no doubt if you pushed the release up a foot, to 8'6, you could get it a bit higher. But not much. possibly 2-3 MPH. 39 MPH jump float is crazy good, and I would think practically impossible for a player below big time college ball. It would require: 1) A tall athlete, 2) A high vertical, 3) a release point of around 9 feet, and 4) some luck. More than likely, the serves at 39 weren't true floats - there was rotation on them that drove them down faster. Even slight rotation will bring the ball down quicker (and make it a lot easier to pass in the process). Of course, I'm just going off of a serving machine and a radar gun, and a release point of 7.5. It's physics. At 4 feet behind the net, you can't keep a float in at anything above 33. |

My teams goal is 36 mph float serve standing or jump. We have several between that and 40mph. We radar it often. That's awesome. Do you find that the speed changes whether or not they jump? This particular athlete, there was no gain in the jump. Only a loss of consistency. What level of college are you at? thanks for the feedback. For a standing 36 mph, I'm assuming they are standing 7 feet behind the serve line with a release point of 7.5 feet, or you have a different radar gun than me!  |

Serving machines are a bit odd.
Every college has players who consistently hit float serves 38mph+. You're right that you have to be up off the ground pretty well to hit 40mph+, but athletes who are 6'2"+ and getting off the ground are probably contacting their float serves closer to 8.5 or 9'.
I have radar gunned plenty of sub-6' high school players who hit true float serves 38mph+.

I came here expecting this to be a thread about Micha Hancock.

I prefer soft serve machines.

We radar the servers on our college team regularly. I find that the speed measurement is not always precise as the ball is decelerating as soon as it leaves the servers hand and when the speedgun catches the serve can vary a little. That said, I think we're contacting above 6' almost exclusively and we're pretty close to the end line at contact. High 30s are pretty much the norm with about 10% 40+ and about 10% a 30-32mph.
I'm interested in the impact of float serving (jump or standing) from much further back (10+feet) - has anyone experimented with that?

What level of college are you at? There was a study done a while back that clocked women's serves in college as follows (I converted from kph to mph) Standing serve: 26-38 mph Jump float: 25-35 mph Power jump: 41-55 mph "The characteristics of the serves in women´s volleyball are: the standing serve (45.9% of serves) is carried out with a range of 43.0 – 61.0 km/h, the float jump serve (37.5% of serves) is carried out with a range of 40.0 – 61.0 km/h, and the power jump serve (16.6% of serves) is carried out with a range of 66.0 – 89.0 km/h."thesportjournal.org/article/normative-profiles-for-serve-speed-for-the-training-of-the-serve-and-reception-in-volleyball/ |

My DDs Club regularly uses a radar gun to clock speeds. Her target speeds for a float serve are between 41 and 43 MPH. That is for a jump float serve.

My DDs Club regularly uses a radar gun to clock speeds. Her target speeds for a float serve are between 41 and 43 MPH. That is for a jump float serve. That would be 25-30 percent faster than the upper range of college players. It would be physically impossible to land a float in bounds at 41-43 MPH with a release point anything under 9 feet. You can't bend the laws of physics. I suspect someone needs new batteries in their radar gun, or a new pair of glasses. |

You can't bend the laws of physics. I suspect someone needs new batteries in their radar gun, or a new pair of glasses. You would be incorrect sir. 21 aces at Red Rock. I am certain about the speeds. She is not a machine though, and that might account for your discrepancy =) |

Post a like to a video of those 41 mph jump floats. THIS I am excited to see! |

Is this one of the Red Rock teams that is serving jump floats @ 41 mph?

Feel free to do the math for the contact point =)
