Performance is key


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

In our previous study, an advanced badminton model study of 21 international elite badminton athletes, the players were quicker on the badminton court wearing Spraino (p= 0,08). These results were not signinficant though. Full-motion capture, with markers on the court and the players, also recorded data on the movements and further data analysis is being conducted to learn about the foot movements during play and badminton-specific movement patterns.

Based on preliminary results, the conclusion for this study was that the reduced friction on the lateral side (outside) 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 movements with and without Spraino© such as 180-degree turning, cutting tasks, etc.

For many years, using preventive measures against ankle sprains has decreased performance. This is particularly the case with ankle braces and to some extent with taping. These methods act as brakes on the joint and restrict movement. Hence, in some tasks in scientific experiments, players perform worse wearing traditional preventive products. For Spraino, the opposite seems to be the case – it does not decrease performance and tends to increase performance in badminton.
