코어운동이 여성노인의 체력, 척추심부근, 하지근기능 및 보행 변화에 미치는 영향

Abstract

This study is aimed at knowing how physical fitness, lumbar deep muscle, low limb muscle function and walking through the core exercise programs for eight weeks affect the old women. Based on the results, we come to the following conclusion.

First, durability, agility, and balance of physical fitness in exercise group showed significant difference before and after the core exercise program indicating that the core exercise has a positive effect on the old women. In the comparison group, there was no change in all variables

Second, by increasing 0°max, 180°max, 45°max, -45°max, 90°max, -90°max in exercise group, examination of lumbar deep muscle and muscle strength before and after the core exercise program has a positive effect on the old women. In the comparison group, there was no change in all variables. Third, examination of low limb muscle function before and after the core exercise program showed not only increasing peak torque of the right leg, left leg in Hip Extension of exercise group but also increasing peak torque of the right leg, left leg of Hip Flexion. There was a peak torque increase of the right leg, left leg in Hip Addction but there wasn't statistically significant difference. besides, there was a peak torque increase of the right leg, left leg in Hip Abduction. There was a peak torque increase of the right leg, left leg in Knee Extension and Knee Flexion. Based on the results, the core exercise program has a positive effect on increasing low limb muscle function. In the comparison group, there was no change in all variables.

Fourth, examination of walking before and after the core exercise program showed an increase of the right leg, left leg on the ratio of forefoot plantar foot pressure in exercise group and showed a decrease of the right leg, left leg on the ratio of rearfoot plantar foot pressure indicating that there was significant difference. The core exercise has a positive effect on changing plantar foot pressure of the old women. In the left and right balance ratio, however, there wasn't significant difference all of them. In the comparison group, there was no change in all variables. also, there was a decrease of the right leg, left leg pressure in Peak pressure. and there was an increase of the right leg, left leg in Step length. The core exercise has a positive effect on improving walking abilities. of the old women.

The study showed that the core exercise has a positive effect on the physical fitness, lumbar deep muscle, low limb muscle function and walking of the old women. However, lumbar stabilization exercise reducing exercise intensity and the limited muscles of lower limb are recommended for the elderly because of weakened muscle endurance and the risk of falls. When a core exercise program was carried, there weren't muscular skeletal system disorder and the injured. therefore, the core exercise are required for the elderly. A detailed analysis and a specific clinical study through a large group of participants will be required in order to use generalized exercise methods for the elderly. Also, it should be focused on developing long-term exercise programs considering individual differences of the elderly.
