Big Data and the Internet of Things brings new level of insight to sports medicine
With the 2015-16 European football (soccer) season underway, we are already seeing the impact of the huge pressure to succeed. In some cases, it is boiling over even this early on, with Chelsea manager Jose Mourinho getting involved in a very public row with his medical staff over the treatment of Eden Hazard during a match. As the season builds momentum, all clubs know one of the most vital aspects of winning trophies is keeping the best players fit so they can play at the top of their game as often as possible.
Last season, just like in every season, we saw injuries that affected teams’ results and possibly their final standings at the end of the season, while other teams capitalized. Arsenal manager Arsene Wenger blamed injuries for the team’s failed title bid, while Real Madrid suffered injuries to players like Gareth Bale and Luka Modric at a crucial stage of the season and lost the title to Barcelona.
There’s no doubt that football clubs, especially the bigger teams, employ first-rate medical staff – physiotherapists, doctors, sports scientists, and so on – but they can only do so much to keep players off the treatment table. Players are human, after all, and keeping them injury-free for such long and grueling campaigns is a big ask. This season again will see players on the end of crunching tackles, over-exerting their bodies, and over-stretching.
What’s less talked about than lost games and league titles when discussing injuries is the salaries paid to injured players. The estimated average cost of player injuries in the top four professional football leagues in 2015 was $12.4 million* per team. Remarkably, every year teams lose an equivalent of 15%-30%** of their player payroll to injuries.
As salaries continue to rise, injuries are becoming just as much of an off-the-pitch boardroom issue as they are an on-the-pitch issue. Consider that if Barcelona’s Lionel Messi, the world’s highest-paid player, spends just a week out injured, the club still has to pay his weekly salary of around $1 million. Not only that, but there’s the huge potential for lost revenue from missing out on UEFA Champions League progress or domestic success because key players are out.
Just as winning seems to mean more than ever, so does football as a business. So with the spotlight firmly on “sweating the assets” – extracting maximum value from the entire squad – clubs are looking to Big Data and Internet of Things technology to consider how player injuries can be prevented with new levels of insight.
Prevention is better than cure
In July this year we saw what could be a huge landmark in the potential of monitoring the risk of injuries, when football’s international governing body FIFA announced its approval of wearable electronic performance and tracking systems during matches. As well as collecting data on statistics like distance covered and heart rate to determine decisions like substitution timings, this also paves the way for wearable satellite devices that keep medical staff updated on the likelihood of a player picking up an injury from over-exertion.
Emerging injury-risk monitoring software uses the concepts of Big Data and wearable technology to pull in and apply mathematical formulas to an exhaustive range of relevant data about players: fitness levels, recent levels of exertion, opponents, age, technique, hydration, even weather. This could help medical staff predict the risk of future injuries with much greater accuracy, allowing them to run simulations and take corrective actions in real time. Imagine a seemingly non-injured key player being substituted during a tightly contested match, only to find out afterwards that monitoring software had indicated he was at a high risk of pulling a muscle. This could very much be a part of the future of professional football.
Going back to Jose Mourinho and his reaction to the Chelsea medical staff running onto the pitch to treat Eden Hazard, it’s interesting to consider how in the future this kind of technology could either support or discredit his position in the dispute. It could help managers work more closely with physiotherapists, as they can visualize the data that shows the risk of injury to players. Although the pressure to win will likely keep on rising, the risk of expensive players injuries could see a big reduction.
SAP’s own injury risk monitoring software is currently in the proof-of-concept phase and will be entering development in the near future. The goal is to build IRM on the SAP Sports One platform as an additional component, and to provide integration to the existing modules of SAP Sports One solution. SAP Sports One was launched earlier this year and is the first sports-specific cloud solution powered by the SAP HANA platform, providing a single, unified platform for team management and performance optimization.
