“There’s a lot of talk of marginal gains in sport at the moment, and we’re looking at very small time periods per stroke – tenths of a second,” explained Jamie Thomas, a biomechanist and performance analyst at British Rowing. “But if you’re taking 200 strokes per race, it suddenly becomes quite a significant margin.”Not only that, but the steady stream of data the technology provides can give other interesting insights about the athletes’ physical state, potentially even assisting with injury prevention and aftercare. “If we’re monitoring people for a long time, we can see whether they may be dropping off, and maybe it’s time to back off their training programme a little bit,” explained Jack Mercer, another of British Rowing’s performance analysts. “That’s an area we’re looking to developing a bit further – as a monitoring and a ‘return to performance’ tool, so we can see where athletes were before they were injured, and ensure they’re back at that level before they go into racing.”

So, what are the tools Mercer and Thomas have to work with? “We instrument the boat with force sensors, angle sensors and accelerometry so we can get individual athlete data from the boats, and also overall data from the hull for how the boat’s moving as a whole,” said Mercer. “We look particularly at the angles the rowers are rowing through, so the stroke length, the forces, the power they’re putting down onto the water and the acceleration of the boat.”This data is then collected from the logger and compiled into reports for the coaches, giving the athletes areas they can improve. While Mercer and Thomas have a big role to play in interpreting the raw information, it’s down to the coaches to decide how to relay the data to the athletes. “We see rowing as a set of graphs,” laughed Mercer.

As of May last year, the official analytics partner of British Rowing is SAS. Their portfolio is an interesting mix, covering clients from global banks to the London Fire Brigade, but they also have a sizeable sporting portfolio across the Atlantic with teams such as the New York Mets, the Orlando Magic, the Washington Redskins and the Toronto Maple Leafs all relying on their data tracking. Rowing, as you might imagine, has its own set of unique metrics.Thomas used to work with a number of football clubs before making the jump to rowing analysis, and the change is not without its unique challenges, chief amongst them the fact that a body of water separates the sports scientists from the athletes. “Working in football, you could have a laptop in a fixed position. You could film the game, do all the stats as you go and feed them back to the coach there and then. In rowing, you’re with a coach, the boat is moving over two kilometres, you can’t stay in one spot and collecting the data is a lot more difficult because you have that distance.”

Another difficulty comes from rowing regulations, which don’t allow the telemetry to be used on race day. They get around this with a simple GPS and accelerometer, and then compare the races to training camps for an approximate comparison. This is a far from ideal solution, not just because GPS is far less accurate, but also because moving the sensors is time-consuming. “To set up an eight, you’re looking at around three hours,” said Thomas. “We do spend a lot of time moving kit between boats and collecting data.”Hopefully, we’ll see their effort proved worthwhile when the British team head to the Olympics in Rio de Janeiro next year, but, if nothing else, it’s a timely reminder of how much technology has transformed sport in such a short space of time. “When I was first rowing, the only thing I had access to was stroke rate on the boat, and occasionally speed if you had an impeller on the bottom of the boat,” explained Tom Dyson, lead coach of the British Paralympic rowing team, speaking about the decade he’s been part of the sport.

British Rowing coach Tom Dyson talks about how boat technology helps the team get the most out of their performance. For more, read the full article here: http://www.alphr.com/technology/1002138/how-british-olympic-rowers-use-technology-to-outflank-their-rivals“Sometimes with the biomechanics data that we take off boats, you’ll pick something up that you wouldn’t see with the eye immediately,” Dyson explained.“It really helps with the coaching side of things – you know a lot more about their stroke than you did before. You used to be confined to what you could see, now you can take the data straight off the gates and see what they’re actually doing through the water. All of these small factors add up to bigger gains in your coaching over the course of a year.”

But how much is the data absorbed by the athletes themselves? “In terms of the biomechanics data, the information is there on paper for them, and if the rowers want to look at it, they obviously can. But I think the coach’s job is to make sure they don’t get too much of that data and [ensure that] it doesn’t replace all the simple things they might be used to, such as seeing their own video data or the feel of the boat itself.”“They have some access to the data in the boat: nearly all athletes will have GPS stroke coaches giving them live speed and stroke rate data. A coach’s job is just to make sure that any additional data they get around the edges is well presented to them and doesn’t overawe what they’re achieving in the boat and the technical changes they’re trying to make.”

What do the athletes themselves make of this? Well, four time Boat Race winner and Olympic bronze medallist Constantine Louloudis is a fan. "Now that materials have improved and we’ve made a lot of positive steps in the past few decades, the new way to get better is to be more scientific, being more intelligent with our training and that means monitoring and using data," he explained at an event in March. And what about Dyson himself? Has the day-to-day analysis changed the way he rows? “Probably not, if I’m honest. I only jump in boats now if I’m coaching,” he explained, underlining that the kind of gains we’re talking about here are best embraced by the professionals only. Although undoubtedly niche, the kind of observations that Dyson, Thomas and Mercer are making on a day-to-day basis could make all the difference in Brazil next year.“We’re there to inform the coaches,” concluded Mercer. “We just hope the information and data we provide supports what they’re seeing on the water and they can use that as an extra variable in their decisions.”

I think it was around the time I stripped off while reviewing a drone that it happened. Slowly but surely, the stuff I’ve been sent to test has gone from phones and laptops to the strange and wonderful, and nothing sums that up better than the InteraXon Muse. Partly because, just looking at the box, we couldn’t really figure out what the damned thing was supposed to do.“Muse – the brain sensing headband. Do more with your mind,” the box proudly declares. What exactly? Will it give me the power of telepathy? “See results with as little as three minutes a day,” it says. “Based on a scientific approach,” it adds. Come on, it’s got to be telekinesis, right? Sign me up for some of that.

The truth is more mundane, but still pretty left-field. The Muse is a headset that looks a little bit like an Alice band. It has five sensors: one in the middle of the head, one on each temple and two rubber pads that go over the ears. These combine to measure your thoughts.That’s not as sinister as it sounds. The InteraXon Muse uses electroencephalography (henceforth referred to simply as EEG to save our sub-editor) to detect electric pulses generated by the brain, which sounds pretty science-fiction, but is actually quite old technology.The NHS uses EEG to investigate epilepsy and dementia amongst other things, and the first human trial took place 91 years ago. Nonetheless, it’s unusual to see the technology commercially available in such a small and – comparatively – stylish package. That’s progress for you.

So what you have is a way of testing whether your brain is working hard or resting, which in the case of meditation is quite a useful way of documenting your journey towards serenity. Albeit, a hugely expensive one. You might find it tough to stay calm when you’ve just blown through £235.I said it was a stylish package and that’s true to an extent, as long as you accept that it's just a plastic headband. The band itself is thin and extremely bendy, leaving me a little concerned I’d damage it carrying around in my bag.InteraXon suggests you may want to use it on the train (I certainly didn’t) so it’s definitely intended to be portable, but it feels like it could do with a case – for my own peace of mind aside from anything else. Given peace of mind is exactly what the InteraXon Muse is supposed to provide, you’d have thought that would be high on their list of priorities.
