[Purpose] This study was conducted to assess the physical fitness of children with
juvenile rheumatoid arthritis (JRA). [Subjects and Methods] In total, 26 children with
juvenile rheumatoid arthritis (JRA) and 25 healthy controls participated in this study.
Using the physical fitness measurement instruments, the Inbody 720 and Quark b2, the
elements of physical fitness that were assessed included muscular strength, muscular
endurance, flexibility, lung capacity, and body composition. [Results] The results
revealed significant differences in muscular strength, muscular endurance, lung capacity,
body composition, functional ability, and health-related quality of life between the
children with juvenile rheumatoid arthritis (JRA) and the control group. [Conclusion]
These results suggested that children with juvenile rheumatoid arthritis (JRA) have
inferior physical fitness when compared to healthy children. The present study was
conducted to develop an accurate evaluation standard to assess the physical fitness of
children with juvenile rheumatoid arthritis (JRA).
