운동과 유제품 섭취 유무가 공복과 식후 주관적 식욕 수준과 혈중 acylated ghrelin 및 peptide YY에 미치는 영향
Effects of exercise and dairy consumption on fasting and postprandial subjective appetitive ratings, serum acylated ghrelin, and peptide YY
There is increasing evidence that dairy calcium may play a role in body weight regulation. A potential mechanism has been postulated to explain a possible role of calcium in body weight control, and yet it remains unclear whether there is a weight-loss effect of calcium or diary. The purpose of this study was to investigate the effect of regular exercise and/or dairy consumption on acylated-ghrelin(AG), peptide YY(PYY) and subjective appetitive ratings in university male students. Subjects were assigned into 4 groups according to their exercise and dairy consumption habits. AG, PYY, and insulin were assessed at fasting state and 60 min after consumption of standard test meal. The statistical analysis was evaluated by ANOVA for reapeated measures. Exercise groups showed lower blood glucose level and higher postprandial triacylglycerol level than non-exercise groups(p<.05). Postprandial insulin elevation was lowered in exercise groups than non-exercise groups. AG was decreased in exercise and dairy consumption group, and PYY was increased in non-exercise groups after meal(p<.05). For subjective ratings, postprandial hunger level was decreased in exercise and dairy consumption group(p<.05). Desire to eat was decreased in exercise groups after meal(p<.05). Our finding suggests that chronic exercise and dairy consumption reduces serum acylated ghrelin and subjective hunger level, which is related with postprandial anorexia.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
