[Purpose] This study examined the effect of low intensity exercise on bone density by
conducting trunk stabilization exercise on females after menopause for 24 weeks. [Subjects
and Methods] Thirty three female subjects over 47 years old and under the age of 53 were
selected and 16 for experimental group and 17 for control group were randomly selected.
Experimental group had performed spinal and pelvic stabilization exercise 30 minutes a
day, 5times a week, for 24 weeks. Except for the daily life, control group did not
participate in any characteristic movement. Bone density of every member in experimental
group was measured using average value of bone density of 1st–4th lumbar through
quantitative computer tomography. [Results] There was a meaningful difference in only
control group about measured value of bone density within each group, experimental and
control group, but there was no meaningful difference in measured value of bone density
between two groups, experimental group and control group. [Conclusion] Through this
research, we could see the fact that although trunk stability exercise could not change
bone density meaningfully, it could maintain bone density. In the future, it is randomly
necessary to study things related this because results of researches can show different
results according to exercise intensity, exercise period, age, weight, hormone status and
mediation period. It is considered that it will help to prevent and treat patients with
osteoporosis a lot.
