Özet

This study was conducted to compare muscular strength and balance of athletes with visual and hearing impairment. The study was carried out with 20 athletes of national Olympic level sports goalball team and 20 athletes of national Olympic level sports hearing-impaired karate team. lsokinetic muscular strength was assessed by IsoMed 2000 device as concentric-concentric at 60 degrees/sec and 240 degrees/sec. Balance assessment was carried out with the Human Body Equilibrium 360 device. There was no significant difference between groups regarding age, height, weight and body mass index (P > 0.05). There were no differences between the dominant and nondominant knee flexion and extension peak torque (PT), % of flexion/extension PT ratio, % of dominant/nondominant PT differences at 60 degrees/sec and 240 degrees/sec velocities (P > 0.05). There was no difference between the groups regarding of both leg static balance (P>0.05). However, single leg standing balance was significantly different between groups in favor of athletes with hearing impairment (P<0.001). As a result of our study it was determined that muscular strength and static balance of athletes with visual and hearing impairment were similar, but athletes with visual problems are likely to have lower levels of single leg balance. Strategies to promote single leg balance in athletes with visual impairments are warranted.
