Here are some 5 simple reasons:
1. Player health tracking
In 2012, then only 24 years of age, Fabrice Muamba, a footballer from Bolton Wanderers, suffered a heart attack on live TV during an FA Cup game. This was not the first such incident on live TV; Marc-Vivien Foe, the Cameroonian player, died on June 26 2003 during a confederation cup game against France. Not to mentioned what happens off-pitch, football club have a duty to look after their players and that's including their health.
Let's be clear, I'm not saying that current health wearable devices could have saved them, but they could have played a great role. Read the signs early to avoid the disaster, as prevention will always be better than the cure.
So how can be big data helps us improve the athletes health? You may ask. I will simplify it for illustration purposes. Teams need to put in a place an IoT and Big Data strategy where athlete will wear various devices during training and games. Think about a heart monitoring bracelets that players can wear during training and games for the physiotherapy team to analyse later or in real time. The devices will record the time, number of foot steps (within a period - in order to differentiate between walking and running) and heart rate. Let's say that player John Smith health is changing during the game, the physios will get alerted of the change of condition and can take appropriate actions. Maybe we can add devices to shin pads so that players do not have to wear uncomfortable devices.
