The aim of the study was to assess ankle strength during plantar and dorsal flexion, and the postural stability in slackliners. The slackliners (n=9) were matched according to age, body mass and height to physical education students (n=9) with no slackline experience. The results showed significantly higher relative ankle strength during plantar flexion (angular velocity 30° . s-1) in the slackline group than in the control group (left: 1.51 ± 0.31 vs. 1.20 ± 0.30 N . m . kg-1, p<0.05, ηp2=0.21; right: 1.55 ± 0.34 vs. 1.21 ± 0.34 N . m . kg-1, p<0.05, ηp2=0.22). There were no significant differences between the groups in other tested variables. The results might be considered in the injury prevention and rehabilitation of the ankle joint.
