It is necessary to understand the physical functions and motor abilities of children with
developmental disabilities and to create an exercise intervention program to support them based on their
characteristics, to help them acquire motor functions and lead better lives. The purpose of this study
was to clarify the effects of an exercise intervention on the motor skills and life abilities of children
with developmental disabilities. Six children participating in a gymnastics class and a day service were
measured and investigated in terms of motor skills, life skills, and center-of-gravity sway. The results
indicated that the degree of disability may influence the changes in motor abilities. Although it was
difficult to capture the detailed changes in the set measurement items, improvements were observed in
daily activities and daily living behaviors by the instructors.
When an existing classroom is used as the target of this study, the age and disabilities of children
with developmental disabilities vary widely, and even within the same age group, there is variation in
the measurement results among individuals. However, when we focus on individual data, the variation is
not as great as that observed among individuals. Therefore, it may be possible to capture the physical,
physical characteristics, and trends of children with disabilities by recording and accumulating detailed
and continuous data on each child.
