GPS trial will put players on track

EVER wondered how hard a collision is between two giant props? Now you'll be able to find out after the NRL approved the use of GPS tracking devices.

The monitors, which are attached to the players' vests and sit between the shoulder blades, will measure heart rates, speeds, distances travelled and the force of impacts during matches.
"A number of clubs have been extremely interested in the benefits that GPS data can provide for several years," NRL chief operating officer Graham Annesley said. "We're now at the point where the majority of clubs are using equipment for training purposes.
"Whilst (NRL chief executive) David Gallop and I were visiting all clubs over recent weeks, it became obvious ... they are anxious to use the equipment during competition matches.
"After consultation with club medical officers, our insurers and the players' association we've agreed to a four-week trial."
Manufacturer GP Sports System managing director Adrian Faccioni said the devices, which are used widely in the AFL, could eventually help with injury prevention in rugby league. To illustrate his point, Faccioni said premier Manly had been using the devices at training for several seasons and had the lowest rate of injury among all clubs.
"From a game perspective what this will allow them to do for the first time is to actually get a true understanding of the physical demands in a game," Faccione said. "They'll know every single second how hard a position is working, how far they run, how fast they run, what their heart rate's doing."
So far 11 NRL clubs have signed on to use the devices and Faccioni is in talks with the Nine Network about displaying the technology during games.
"We were hoping to do our first broadcast this weekend but we've had some technical glitches so we'd hope at least once in the next four weeks we'll actually do some live heart rate from some key players in Friday night games," Faccioni said.
"With time we'll add distances, we'll add speeds, we'll even be able to add impact so when two forwards smash into each other we'll be able to tell you how hard they ran into each other."

Other benefits:

They can track a player who is out of position.

They can track a player wandering into a pub toilet. 3 bleeps of the screen going in together = trouble!

They can track a player going into a rivals league club for contract talks.

I wonder what Watmough's head looks like on Google Earth.

I've always wondered what the possibility would be for having this type of stuff used for real-time streaming to the net.

Would be a great little addition to the NRL Live Updates system to have a little field with all the men running around on it :lol:

We trialled this 2 seasons ago in a Dragons V Dogs match.

Patten was actually docked at a certain time going at faster speeds than Ingis and Slater.

They re-checked what point in time it was in the match and it was just the impact of a hit in which he got hammered. He fell back that quickly

Most Pro sports teams that get this data are extremely protective of it.

i'd imagine NRL clubs would be essentially the same, they are with the stats. ie they don't want people knowing that over 10m some big fat guy is the fastest bloke on the team. there'd be a whole bunch of data that they didn't want public. unless the NRL mandate that some data must be made available to the TV networks it's not going to happen.

Didn't Manly use this in the Leeds match?

Be great if it can help with the reffing of a game... maybe speed up the video refs call;-)

Heres a article about the devices being used tonight via Bula at the Baistand.

Melbourne Storm players to wear GPS monitors in match
WELCOME to the computer age. A brave, new era of micro chips and satellite receivers. A freakishly evolved realm where every step and every tackle is measured and quantified from the heavens.


And leading the pack is the Melbourne Storm, whose stars will tonight go where no rugby league player has gone before.

History will be written and the future changed forever at Olympic Park, where the hosts will become the first NRL side to wear GPS tracking vests during a competition game.

If pre-game testing is any guide, the results could be scary, especially if you happen to be a St George Illawarra ball-carrier.

Run into Melbourne lock Dallas Johnson and expect to be greeted with a force four times greater than a space shuttle launch.

A smack almost three times greater than a Formula One car at full speed. A collision to test the physical tolerance of a fighter jet pilot.

When Johnson tackles, he hits you with a G-force of 13. When this was pointed out at training recently, the hard-nosed Queenslander screwed up his nose.

"That wasn't during a game," he said. "I wasn't going 100 miles an hour, flat-out."

He will be tonight, so watch out Dragons. And so will teammates Billy Slater and Greg Inglis.

Both were tracked by GPS during a trial against Brisbane on the Sunshine Coast two weeks ago and returned incredible speeds.

Tipping the scales at 107kg, Inglis would not be disgraced in a 100m Olympic sprint. During a match, he sears 9.5m every second.

Although generally considered to be the fastest man in purple, Slater is actually 0.3m behind.

Quantification of their skills has generated much interest among these competitive beasts.

Melbourne's sports science co-ordinator Troy Thompson says the players are now trying to outdo each other at training sessions with the data suddenly available to measure who is the fastest, strongest and fittest.

Better yet, it measures the results instantaneously.

Recently, Johnson whacked new prop Matt Cross with a bellringer at training while wearing the GPS vest.

"Wow!" Thompson yelled as he saw the tackle's G-force register on his laptop. "That was an 11.8."

Cross struggled to regain his feet.

"But the biggest thing among the players is seeing who runs the fastest," Thompson said.

"The information has been good because it makes them competitive. It makes them strive for better results.

"But the trick for the coaching staff is not to give them too much information. For instance, we don't tell them about how much distance they run at training.

"If they ever found out, they'd probably tell us to ease off."

Melbourne haven't invested in the technology to engender healthy rivalry among their players.

As Thompson points out, the data is generally used retrospectively to measure the strain on an individual during a game or training session.

By collating the data with previous results, the coaching staff can make an educated judgement on how much energy a player has expended and then tailor his recovery program accordingly.

"Last year, we were using the GPS on four players per training sessions, but now it's 20," Thompson said.

"Across the board, we can measure physical characteristics and workload for each player during a session or a game.

"The upshot is to tailor their recovery, so if they've been hit with greater impact or run more metres, we'll go a bit lighter on them the following week."

But the most exciting aspect for fans is the immediacy of the results.

During tonight's game, the Storm's brains trust will have access to all data live, enabling coach Craig Bellamy to take it into account with his use of the interchange.

For viewers at home, however, its real value will emerge when a club gives Channel Nine permission to broadcast the data as a game unfolds.

Given tonight's game is a first, the Storm have denied permission.

But updates on tackle intensity and burst speeds will be as inevitable as the Hawk-Eye and Hot Spot features couch potatoes now take for granted during cricket telecasts.

Btw that 9.5m/sec by Inglis equates to running 10.52 sec in the 100m. You might say he couldnt keep it up, but take into account the time is on grass.....in footy boots and gear :shock:.

And GPS technology still has an error of 5m?

Still remember a fire I went to on Middle Brother Mountain a few years back. Up on top, at 500m asl, we took a GPS reading. Told us we were 6m below sea level at low tide.........

Where at they going to wear these during the game? I wouldn't like to see someone injured from a piece of plastic or metal from one of these things.

No it doesn't. In a 100m race you go from a standing start.

I am interested to see how many kilometres certain players in certain positions travel in the 80 minutes...

I thought maybe they were considering using these in the evenings on the weekends for when they are out "socialising".

they were meant to be worn during 2007 but were banned after most of the club nrl doctors deemed them to dangerous, however they have become smaller and more safer

apparently theyre similiar to a chest protector similiar to the one worn by braith anasta during the 04 finals series so they must have been found to cause no harm

I was just re-watching the QLD Derby and noticed a few guys, including Hunt and Folau, wearing these GPS bras under their jerseys.
