초록
본 연구에서는 당 부하를 통한 전기자극강도 차이에 의한 혈당치의 변화와 운동요법과의 비교를 실시하였다. 경산시 D대학에 재학 중이고 당뇨병이력이 없는 남녀 대학생이 연구에 참여하였다. 실험은 당 부하 후에 1) 30분간의 휴식, 2) 30분간 운동강도 40%HRR의 treadmill, 3) 30분간의 EMS 최대강도, 4) 30분간의 EMS 1/2 강도에서 시행하였으며, 이후 2시간 동안 혈당 변화를 측정하였다. 그룹별 시점에 따른 혈당의 변화는 휴식, treadmill, EMS 최대강도, EMS 1/2강도의 시점에 따른 반복측정 결과 통계적으로 유의한 차이가 나타났다. 그룹간 혈당 비교에서는 당 부하 후, 처치 종료 후 휴식과 treadmill에서 유의차가 나타났다. 그룹간 혈당 비교에서는 그룹 간 당 부하 후, 처지 종료 후 treadmill군과 EMS 최대강도군, treadmill군과 EMS 1/2군에서 유의하게 나타났다. treadmill에서 혈당조절효과와 변화폭이 높게 나타났으나, 휴식에서 낮게 나타났다. 이러한 결과는 treadmill이 EMS보다 근 수축에 사용되어지는 근육량이 많고 골격근 수축에 의한 당소비량도 EMS에 비해높게 나타난 것이 원인으로 파악된다. treadmill의 경우 근 수축을 가장 많이 사용한 것으로 추측되어 혈당의 감소를 가장 크게 나타났으며, 이와 관련하여 EMS를 적용하였을 경우에도 근수축이 일어나 근육의 수축 등에 의해 혈당이 조절된 것으로 사료된다. 본 실험결과 treadmill을 통해 직접적 근육의 운동이 효과를 제일 크게 나타내지만, EMS 1/2 등의 전기자극을 통해 근수축 형태를 나타낼 때도 효과를 보일 수 있을 것으로 사료된다. 이상의 결과로부터 EMS를 통한 당 대사 촉진 효과에는 EMS의 강도도 영향을 미치는 것으로 고찰되었으며 향후, EMS의 시행 부위, 강도의 비교나 장기적인 효과에 대해서도 검토가 필요할 것으로 사료된다.
Abstract
In this study, the comparison by the difference in electrical stimulation intensity through glucose load and the comparison with exercise therapy was conducted. This study was conducted after obtaining sufficient understanding and consent for the experiment in male and female college students aged 19 to 26 years old who are enrolled in D University without a history of diabetes. 75g of glucose was used for the glucose load test, and a portable blood glucose meter was used to measure the blood glucose level. The experiment was conducted at 1) 30 minutes rest, 2) 30 minutes exercise intensity 40% HRR treadmill, 3) 30 minutes EMS maximum intensity, 4) 30 minutes EMS 1/2 intensity and blood glucose level over 2 hours change was measured. As a result of the experiment, there was no significant difference in blood glucose level before glucose loading between each group. The change in blood glucose according to the time point of each group was statistically significant according to the time point of rest, treadmill, EMS maximum intensity, and EMS 1/2 intensity. In the comparison of blood glucose levels by time point between groups, there were statistically significant differences between rest and treadmill after glucose load and after treatment. In the comparison of blood glucose levels by time point between groups, there was a statistically significant difference between the treadmill group and the EMS maximum strength group, and the treadmill group and EMS 1/2 group after glucose load between groups and after the end of treatment In the case of treadmill, it was estimated that muscle contraction was used the most, and thus the decrease in blood sugar was the greatest. In this regard, even when EMS was applied, muscle contraction occurred and blood sugar was controlled by muscle contraction. As a result of this experiment, direct muscle exercise through a treadmill shows the greatest effect, but it is thought that it can also show an effect when showing a form of muscle contraction through electrical stimulation such as EMS 1/2. From the results, it was considered that the strength of EMS also affects the effect of promoting sugar metabolism through EMS.
