운동 강도에 따른 여대학생의 혈중 leptin 농도 = The effects of acute exercise with two different intensities on plasma leptin levels in colleges female students

다국어 초록 (Multilingual Abstract)

Leptin is an adipocyte-derived hormone that has been shown to regulate body weight and thermogenesis in human and animal. The objective of this study was to investigate the effects of exercise on plasma leptin responses. The 7 college female students were participated in acute bout exercise with two different intensities. It was examined the exercise intensity in acute bout exercise affected the plasma leptin response. Resting plasma leptin levels were significantly different 70% from 50% after acute bout exercise with two different intensities (Omin and 15min after exercise). Resting plasma insulin and glucose levels were not reduced as a result of acute bout exercise both intensity (p<0.05). Resting plasma FFA levels of were significantly different 70% from 50% after acute bout exercise (180min after exercise, p<0.05). Resting plasma glycerol levels were significantly increased after acute bout exercise with two different intensities (pre<0min=15min (70%), pre<0min=120min=180min (50%), p<0.05). Resting plasma lactate levels were significantly different 70% from 50% after acute bout exercise with two different intensities (Omin, 15min, 30min and 15min after exercise). In conclusion, reduction in plasma leptin levels were independent of plasma insulin and FFA levels. There are no difference between exercise intensity. These data show that reduction in plasma leptin levels were more associated with negative energy balance reduced by amount of exercise than exercise intensity.
