Factors Related to Exercise Capacity, Conditioning, and Secondary Disorders with Relation to Classifying in Japanese National Team Wheelchair Basketball Players

Abstract

We investigated the correlation between classifying and secondary disorders (namely, deep tissue injury [DTI] and shoulder pain)， and between classifying and conditioning (namely, sleep status and nutritional status)， in Japanese national team wheelchair basketball players (male: 14-20, female: 18-21)．DTI was evaluated using ultrasonography, and shoulder pain using the Wheelchair User’s Shoulder Pain Index. Sleep status was assessed using the Pittsburgh Sleep Quality Index, and nutritional status using the Food Frequency Questionnaire (version 3.5)．No significant differences were found for the relations of secondary disorders and conditioning with each class. However, athletes with sever disability were more likely to suffer from DTI, and athletes with mild disability were more likely to suffer from insomnia. We therefore concluded it is necessary to periodically and continuously investigate secondary disorders and conditioning.
