초록

운동과 식이요법을 병행한 체중감량 프로그램에 참여한 여성 비만인의 체지방량, 안정시대사량, 그리고 갑상선 호르몬 차이를 비교할 목적으로 실험한 결과, 체지방량, 체지방율, 체표면적이 유의하게 감소되었고, 안정시대사량 예측치와 실측치 모두 유의하게 감소되었지만, 갑상선 호르몬의 변화는 나타나지 않았다. 안정시대사량과 신체요인들과의 상관분석 결과, 제지방 체충이 가장 밀접한 관계를 보였으며, 안정시대사량과 갑상선 호르몬들과의 관계에서는 TSH와 가장 밀접한 관계를 나타내었다. 결론적으로 8주간 체중감량 프로그램 참여로 체지방은 효과적으로 감소되었으나, 갑상선 호르몬 차이는 없었고 체중감소에 비해 제지방이 유지됨으로써 안정시대사량의 감소는 최소화되어, 에너지 대사작용에 긍정적인 영향을 준 것으로 사료된다.

The purpose of this study was to examine resting metabolic rate (RMR) and thyroid hormonal (TSH, $T_3$, and $T_4$) changes following weight loss by diet with regular exercise in obese women. The subjects of the present study were 7 women who were above 30% body fat. The subjects arrived into the laboratory in the morning after 12 hour overnight fasting. All subjects measured RMR, % body fat, and fat free mass at weight loss program start time, after 4 weeks and after 8 weeks. All the RMR values were expressed as absolute value (kcal/day), absolute value/FFM (kcal/day/FFM), and absolute value/BSA (kcal/$m^2$/hr), and were calculated predicted RMR value minus actual RMR value. Also, correlation of blood thyroid hormonal (TSH, $T_3$, and $T_4$) secretion and RMR were analyzed. There were significant differences in weight, % body fat, and BSA following diet with exercise (p<0.05). Also, there was a difference between predicted RMR and actual RMR value following weight loss (p<0.05). We also examined the hormonal changes according to weight loss. After weight loss, the level of TSH and $T_4$ were higher than before. But there were no significant differences. Also, the level of $T_3$ was lower than rather before but there was no significant difference. Among the anthropometric factors, FFM was highly correlated (r=0.761) with actual RMR value before weight loss. Also, there was a correlation (r=0.771) with actual RMR value after weight loss. Therefore, actual RMR expressed as FFM increased in weight loss program by diet with exercise. There were no changes in the level of thyroid hormonal TSH and $T_4$.
