Swim Smarts

In cooperation with Finland's national swimming team and archery association, VTT Technical Research Centre of Finland has developed wearable technology for improving sports performance. Wearable sensors can be attached to, say, a swimmer's hand paddles or an archers' equipment. From there, data is wirelessly transferred to the coach's smartphone or tablet. The sensors embedded in the paddles provide surprisingly precise and varied data on the wearer's swimming technique. This covers stroke length and changes in it during swimming, the relationship between the outward stroke and recovery, the structure of the stroke and the average pull, the hand position and the pressure exerted by the stroke in different directions.
