Twenty male, regional-level team sports (soccer, handball, basketball) athletes
(age, 24.3 ± 3.4 years; height, 1.84 ± 0.05 m; weight, 81.3 ± 7.4 kg; 16
right-leg dominant, 4 left-leg dominant) participated in the study. Based on an
a priori power analysis, 20 participants was considered sufficient to identify a
difference of 4° in maximal inversion angle between 2 conditions (alpha, .05;
power, 0.8; SD, 6°
1 (link)). Participants were injury-free in the 12 months
preceding data collection and signed written informed consent before their
participation. Only 1 participant had undergone anterior cruciate ligament
reconstruction surgery, approximately 3 years before data collection. The other
participants had not undergone lower extremity surgery. Four participants
reported previous ankle sprain injuries >12 months before data collection
(ranging from 2 to 13 years before data collection; 2 participants sprained
their ankles on the left and 2 on the right side). All methods used in the study
had been approved by the research ethics committee of the university.
