Comparison of range on movements in joints among former professional volleyball players and men population not engaged in sport
Abstract
Aim: Aim of our contribution is to point out the differences of joint range of motions in former professional volleyball players (Extra league, 1 League) and men in the same age group who do not perform sports. Methods: Examined group consisted of 40 men ages 50-60 years old. 20 of them were former professional volleyball players and 20 non sportsmen.
Goniometric (planimetric) method used for measurement; the angle that can be reached in the join via active or passive movement is measured. Two-arm mechanic goniometer was used in this research.
The measurement of active range of movements was performed twice by a trained physiotherapist and the better score (bigger range of movement was recorded). Results: The biggest differences were found in the carpal joint, particularly in ulnar duction, where the difference is 25%.
The second biggest difference was found in dorsal flexion of the ankle joint (repeated landings). The third biggest difference was observed in plantar flexion of the ankle joint, the difference was 17%.
Conclusion: From the results can be seen that joint range of motions in former professional players are smaller than in male population not engaged in sports at all, or only on recreational level.
