Interventions
Mediolateral weight-shift training was performed via a VR wasp game (see Supplementary Fig. The 25-min training was divided into 10 blocks of 2.5 min with a 30 s rest period in between blocks. A longer break of 2 min was provided after five blocks with the opportunity to rest on a chair. Participants were instructed to hit as many wasps as possible, while maintaining their base of support and initial posture. To make the training more challenging, the wasps were randomly placed at positions higher or lower than the midline and were made bigger or smaller. As such, participants had to pay constant attention to the position and size of the wasp. Verbal feedback and encouragement was provided throughout the training. Participants in the CTR were asked to relax for 25 min, while seated.
