Performance is key


Performance is crucial to athletes doing competitive sports. We have therefore tested Spraino in a range of different studies to make sure, that performance is not decreased. Actually, it turns out that Spraino tends to increase performance.

In our last study, an advanced badminton model study of twenty-one international elite badminton athletes, the players were quicker on the badminton court (p= 0,08). Full-motion capture, with markers on the court and the players, also recorded data on the movements. The preliminary data has been presented, but more data analysis is being conducted to learn about the foot movements during play and badminton-specific movement patterns.

The conclusion for this study so far was that the reduced friction on the lateral side of the shoe caused by using Spraino did not affect performance under simulated match-play. Similar conclusions have been drawn from biomechanical studies at AAU investigating different movement with and without Spraino© such as 180-degree turning, cutting tasks, etc.

For many years, one of the dilemmas using the prevention methods for sprains, has been decreased performance. It is particularly true with ankle braces and to some extent with taping. These preventative methods act as brakes on the joint. Hence, in some tasks in scientific experiments, players perform worse on top of a decreased comfort. For Spraino, the opposite seems to be true – it does not decrease performance and tends to increase performance in badminton.
