Key resources for volleyball coaches

There’s a list of tools and resources posted up on the USA Volleyball blog. Some of the stuff is the sorts of tools we can use on the court and/or should have in case of emergency. Some of them I’m sure you’ll have in mind. You might already have them in your coaching bag. Some might not have occurred to you before. There’s also a list of computer programs and apps. Here’s the latter.

BAM Video Delay –  show “mirror like” on the face of the tablet whatever the lens is set to show, but by rubbing your finger on the face of the tablet, you can delay longer or shorter up to 2 minutes.  Player does whatever on the court, then before the 15 seconds, or whatever time set amount, goes over to the tablet to see their skill performance. Coach does not need to be present. http://www.orangeqube.com/bustamove/.

Dartfish Express – or Ubersense, or Coaches Eye – fast replay video options for in practice feedback, which includes the ability to draw lines/angles, and more to assist.

Scoreboard  – Simply turns your tablet into a “flip score” device  easy to read from across the court. https://itunes.apple.com/us/app/scoreboard-free-version/id496758984?mt=8

VBStatsHD – Does all the stats/video synching you want and more – not cheap – but not expensive at $30. For those who want a powerful app. – http://peranasports.com/?portfolio=vbstatshd-demonstration

ACE Stats/Tap Recorder – Low cost fast stat software.  http://www.ace4vb.com/smart-device-store.html

I’ve used a couple of these apps myself. I wrote about how I’ve used video delay, and also about TapRecorder. I’d love to hear your experience with any of the above, or whatever other applications you’ve used.

The good and the bad of volleyball statistics

Coach Rey has an interesting post discussing the use of stats in modern volleyball. It includes an idea for his own sort of team scoring metric. I found his comments about how complex and advanced stats are these days to be quite interesting. I’d started having that feeling as well at times. I can imagine how overwhelming the mass of numbers are for some. In particular, Rey brings up how confusing things can be for players. I think that is probably something which varies from player to player. Some don’t care about stats while others get quite into them.Personally, from a player perspective, I like to use stats to help track development and performance over time. I also like to provide points of comparison where appropriate.

I can imagine coaches getting too caught up in the numbers. This is a little bit of the PhD in me talking. The fact of the matter is that as coaches we tend to get only small sample sizes. You need a fairly large number of observations to draw proper conclusions. This is fine in a situation where you can track lots of reps (like serve receive over several training sessions). It’s more problematic when you have to make quick judgements in the middle of a match. For example, when a hitter has 10 swings, 1 kill or 1 hitting error either way has a major impact on their hitting %.

And let’s face it. There’s a lot of stuff that goes on in a volleyball match which doesn’t show up in the stats. Having numbers at hand makes it seem like we can make nice clean assessments. The bottom line, though, is that we’re still dealing with people. People aren’t machines. Inevitably there are things they do (or don’t do) which aren’t so easily converted into neat objective measures. Some coaches seem to get so obsessed with the numbers that they forget this fact.

Don’t get me wrong! Stats are quite handy so long as one doesn’t get carried away.

While coaching in England I was jealous of the stats my coaching peers back in the States got. There is very little in the way of statistics there, and most of what does exist comes from coaches collecting their own. I did a bit of stat-tracking in training to give players progress reports and to do some comparisons. At one point I had an assistant who tracked some things during matches when he was available. That’s about as far as it went, however.

I struggle personally as a head coach to keep stats during matches because I find it distracts me from observing the big picture of what’s going on with my team (different when I was an assistant). I wouldn’t have minded having consistent box score type stats provided to me, though. 🙂

Coaching Log – Nov 25, 2013

This is an entry in my volleyball coaching log.

With matches for everyone coming up, playing 6 v 6 in segregated teams was the main theme of training. The B side focus was on teamwork, calling the ball, staying switched on, and not looking for someone else to play the ball. I told the B side focus was on continuing to be aggressive in attack, but underlying that was also an evaluation of the setter position. This harkens back to my observations from the Student Cup performance.

One of my primary OHs thus far is also a capable setter (sets for her German club team). I haven’t used her there thus far because I saw her value as an attacker as being in the area of greater need. Even had to use her at MB on a couple of occasions when we were thin on bodies. In the last match of the Cup I had her do some setting for the first time and it was an eye-opener just from the warm-ups. With other hitters coming along, I no longer feel so concerned about losing out on her as an OH.

At the same time, our starting setter up to now is only here for this term. As a result, I need to evaluate our setting options moving forward in any case. One of the teams on the schedule for the upcoming matches is currently top of the table, having beat us a couple weeks ago. We need to be at our best for the rematch, so I took a hard look at the setting in training to start evaluating who would give us our best chance at victory.

Following what was basically a pre-match warm-up, we went straight into 6 v 6. It started with a game featuring one side serving 3 times in a row (not counting missed serves). I put the starting setter with the B team (their setter was missing) and the other one with the A team. I used that to gauge a rough baseline point differential I could use to spot the B side in the straight-up games to follow. I came up with 8.

We then played two regular games which started with the B side serving, up 8-0. In the first the starting setter was with the A side. I then flipped setters for the second game. The A team lost the first set 25-20, and the second 25-23.

Stats were kept for all three games to evaluate offensive effectiveness as a way to compare the setters. More of this needs to be done in the next training, but the early results show quite a stark difference. The kill % for the team when the starting setter ran things on the A side was was 21% vs 36% for the former OH, while the hitting efficiency numbers were .063 vs .190. Need to see if that gap holds up.

Volleyball Coaching App Review: TapRecorder

A while back, I looked into apps I could potentially use to help keep track of statistics in practice. I didn’t want to resort to going the old clipboard method. I wanted something that went beyond just match type stats. That’s in terms of being able to cover the whole squad at once rather than just 6 players. I also want to do more than just the standard kills, blocks, digs, etc.

Most of the apps out there are oriented toward match stating. I did find one which seemed to fit the bill, though. That was TapRecorder from Volleyball Ace.

TapRecorder What really attracted me to TapRecorder was its flexibility. It is based on a spreadsheet model, making it highly customizable. Basically, you can keep track of just about anything you like. In my case, I could do something like putting all my players on a single screen and track their passes in a serve receive drill.

The app comes with a set of sample recordings (downloadable from the website). You can use either on their own or as the basis for developing your own templates. Creating new recording sheets is pretty easy. I can be a bit tedious when you need to add in a long list of players, however. There’s a companion application which will allow you to do it on your computer for upload to the tablet. I haven’t used it yet, though.

As with any stating app, there’s going to be a little bit of a learning curve, though designing your own recording sheets helps to at least make things more intuitive for you. And obviously if you’ve only got TapRecorder on one device only one coach at a time can use it, which is no different than working with a clipboard. You’d need multiple versions of the app to have more than one coach stating, but there’s a companion desktop application (Excel-based) which will allow you to aggregate data from multiple recordings. I haven’t used that yet myself, but when I do I’ll add my observations here.
