The purpose of this study is to investigate the effects of stretch on
children's flexibility in practicing sit and reach, trunk extension and
flexibility of hip joint. 60 students in group A(first and second graders), 60
students in group B(third and fourth graders) and 60 students in group C(fifth
and sixth graders) in B'elementary school of K province were examined. Each
group was divided into experimental group and controlled group. The effects of
stretch on flexibility in each group were compared. The result of this study can
be summarized as the followings.
1. In case of sit and reach, the records of students in group B were improved
more than other groups after stretch. In case of trunk extension, the records of
students in group A and B were improved more than those of the students in group
C. In case of flexibility of hip joint, there was no difference in records among
each group.
2. The record was improved according to the experimental period. After two
weeks, the records of sit and reach and trunk extension were improved. And after
four weeks, the record of flexibility of hip joint was improved. Stretch can
affect flexibility after Just a short period.
3. In case of sit and reach and trunk extension, the record began to improve
after stretch three times a week but in case of flexibility of hip joint, the
frequency of stretch had no effect on records.
4. The flexibility of experimental group was improved after a few weeks of
continuous stretch. But the flexibil ity of control led group wasn't improved so
much. Therefore the effects of stretch on flexibility have a significant value.
