Abstract
The aim of the study was to assess ankle strength during plantar and dorsal flexion and the postural stability in the slackliners and to compare the results with the active subjects. The slackline group (n=9) has the similar anthropometric characteristics as the control group.
The results show significantly higher relative ankle strength during plantar flexion (at angular velocity 30°/s) in the slackline group than in control group (left: 1,51 ± 0,31 vs. 1,20 ± 0,30 N•m•kg-1, p<0,05, η2=0,21; right: 1,55 ± 0,34 vs. 1,21 ± 0,34 N•m•kg-1, p<0,05, η2=0,22). There were no significant differences between groups in other testing variables (postural stability, ankle strength in angular velocity 120°/s, time to peak).The results indicate, that the activity on slackline could be used as the prevention of injuries, ankle rehabilitation programs and could use as the postural stability exercise.
