How Belgium apply science to help Hazard and co

THE English influence is unmistakeable whenever Belgium’s superstars reunite for international duty.

Many of them - Eden Hazard, Romelu Lukaku, Vincent Kompany and Kevin de Bruyne to name just a few - ply their trade in the Premier League.

Boss Roberto Martinez spent 21 years in England as both player and coach, usually with Geordie assistant Graeme Jones and Welsh fitness coach Richard Evans by his side. The Red Devils' other assistant manager, Thierry Henry, requires no introduction to English audiences.

And as Martinez and his coaches run the players through their paces at the Tubize training centre near Brussels, an Irishman can usually be seen on the sidelines, looking intently at an iPad.

This is Turlough Hendry, a sport scientist with Newry-based STATSports, who have supplied GPS equipment to the Belgian team since Martinez took over in August 2016.

“We brought our training methodology with us from the Premier League and STATSports were a key part of that," fitness coach Evans tells TGG.

“Although the players are all used to using GPS, none of it was really in place when we arrived - certainly not to the level we’re using it now.”

For their last two training camps, Belgium have upgraded to STATSports’ third-generation GPS system, Apex, which has been described as the most powerful wearable in sport.

“Roberto is a master tactician and loves his technology too,” Evans adds. "The data we get from Apex is extremely accurate, which means we can hopefully find a sweet spot where we're neither overloading nor underloading the players.

“What we want ultimately is to get the most from the players while they are with us but to also hand them back to their clubs in very good condition.”

Evans and Hendry gave TGG an in-depth insight into exactly how Belgium use GPS - before, during and after their international training camps:



PLANNING:



Evans first met Martinez in January 2003, when he was working at Swansea City and carried out the Spaniard's medical. When Martinez became manager, Evans was his Head Physio, and they've been together ever since, at Wigan, Everton and now the Royal Belgium Football Association.

“We’ve been on the other side of the fence, so we understand how the clubs feel,” explains Evans, whose title is Head of Team and Individual Fitness.

“Often, at Swansea, Wigan and Everton, we didn’t have a clue what our players were doing when they were away on international duty. And talk about spikes. I remember situations when players came back having tripled their workload in the 10 days they were away, which has big implications for injury risk.

“Now we try to provide clarity for the clubs and GPS helps us do that.”

Hendry says this is one of the main reasons why so many international teams, including Belgium, who hadn’t really seen the need for GPS, have now become STATSports clients.

“Load is a big thing and being collaborative and transparent with data helps to manage that and build trust,” the sport scientist says.

“So a couple of days before every camp I contact all the clubs who are STATSports clients - Manchester United, Everton, Tottenham, Burnley and so on - and they will send me the two weeks’ of data from their last training session.

“I can then put that directly into my laptop and by the time the players turn up for training on a Monday, Richard can see exactly what they’ve been doing and what condition they’re in.

“He can make a decision on day one about who does what, making it very customised.”

Evans adds: “With that information, we can periodise our eight to 10 days of camp in a way that maintains those who are playing regularly or gives a top-up to those who haven’t been playing, in high-speed running for example.

"We work with the clubs to bespoke the sessions to enhance or maintain what they’re doing. An international squad is made up of between 25 and 28 players and of those you can guarantee that 10 will have been playing at the highest level, Saturday-Wednesday, while others will have been on the bench or not playing at all.

“Roberto will want detailed information on every single player, so I'll tell him, ‘he needs to be protected here, make sure he doesn’t do so much distance,’ and so on. We can tailor each session to the club’s needs and ultimately Roberto’s needs, because he needs to win games.”



TRAINING:



“Everything is set up in the gym, ready for the guys to put on their GPS units when they come in for a little bit of pre-activation," Hendry explains.

“I’ll then go out and set up my live antenna and place the miniature beacons across the pitch. From the time the players run onto the pitch I’ll be running live analysis.

“Richard will conduct his warm-up, lasting 10 to 15 minutes, and he can quickly scan my iPad if he wants to check the physical outputs, to say ‘that’s exactly what I wanted to do.'.

“We're able to monitor a number of players and a number of metrics simultaneously."

After that, the players go off for a session with Martinez and his coaches. The Spaniard uses a version of tactical periodisation, which means work is done within a tactical framework and almost exclusively with the ball. Sessions are filmed and video analysis carried out later on.

If a player is being used in a different role than he is accustomed to, meaning his outputs will change, then, again, Evans will liaise with their club.

“With Roberto’s system with the wing backs, we have sometimes used midfielders in those role,” the Welshman explains.

“We will make the club aware of that, because a player accustomed to doing 1000m high intensity running is suddenly doing 1300m or 1400m, so that has to be taken into account as well.”

Evans says the physical objective of the sessions will be to “gradually increase the outputs in volume and intensity” and that GPS is used to ensure players hit their own individual benchmarks.

The human element is never lost though.

“Objective data is very important, but you also have to talk to the players and understand how they're thinking and feeling. It's a collaborative process.”



REPORTS:



“The biggest benefit of Apex is its ability to sync my drills back to the desktop once training has finished," says Hendry, who has worked as a GPS analyst at every Belgium camp since Martinez took over.

"Running live means I can have a report ready immediately after training if I want to, straight from the app, but what we normally do is download.

"So I print out a PDF report for Richard looking at various metrics. There will be the standard ones, like distance covered, but we can also split that up into high speed running, explosive distance, maximum speed and so on.

“We also conduct the top three heart rate zones, so 80 to 90% of capacity, 90 to 96% and 96% and above. I’ll do a report on the session as a whole and also on each individual drill for each individual player per minute.

“The management team will take a look at that as a group, often after dinner, and talk it over with the video analysts.”

Martinez, Henry and Jones "take an active interest" in the GPS data, "but essentially leave it to me," Evans says. "If there is a problem, they will come back.

“If a player has been below his benchmarks, we can see those sensitivities. In that case I'd probably have a chat with the individual to find out what he thinks happened. It may be he was a bit tired or that other external influences like a problem at home inhibited his performance.”



AFTER CAMP:



This is where Evans and Hendry return the favour that they got from the clubs ahead of the camp.

“If the camp finishes on the Sunday, the clubs will be getting the raw files by the time they get their players back on the Monday via the Exchange. They will all have their own training stress balances and so on and will want to see what their players was doing with us.

"They can pull out the numbers as if they had been doing the sessions themselves, so there is no interruption in the data.”

At the next camp, Evans plans to start using the Apex smartwatch, which will be particularly useful for rehab work.

Despite being a fan of data, the Welshman says you cannot overlook human factors such as friendship and team spirit.

“They players are a talented bunch - some of the best players in the world,” he says, “ but they also get on very well, having played together at youth levels, developing relationships that go back many years.

“You can see the level of friendships that are there, which are great. They’ve been open, welcoming and very professional since we came in, allowing us to implement a few of our things, like the GPS.”

England beware.
