Relationship Between Body Composition and Muscle Strength in Early Adolescence Goal-Ball players with Visual Impairments

Abstract

adolescence goal-ball players with visual impairments. Methods: Thirteen early adolescence goal-ball players with visual impairments that are goal-ball players participated (mean age 13.54±1.27 years, height 155.23±10.86 cm and, body weight 48.23±10.43 kg). Body composition measurements that were assessed included body mass index, body fat percentage and skinfold (abdominal, subscapular, triceps and suprailiac). Participants were also assessed on several strength measurements including standing long jump, the right hand grip, left hand grip, vertical jump, leg strength, sit-up and push up. Results: Positive correlations between ages and height with the standing long jump, the right hand grip, the left hand grip, vertical jump were found in the early adolescence goal-ball players with visual impairments (P < 0.05). Negative correlations were found between body mass index and body fat percentage with standing long jump, vertical jump, sit-up (P < 0.05) and among skinfold (subscapular, triceps and suprailiac) with standing long jump, the right hand grip, left hand grip, vertical jump, push up (P < 0.05) and between abdominal skinfold with standing long jump, the right hand grip, left hand grip, vertical jump, sit-up, push up (P < 0.05). On the other hand, there was not a correlation between body weight with muscle strength and leg strength with body composition (P>0.05). Conclusins: In an assessment of body composition and muscle strength, it was found that body weight did not significantly impact muscle strength in early adolescence goal-ball players with visual impairments. This finding could be of importance for understanding the role of muscle strength and body composition in routine training of goal-ball players.
