강도에 따른 남자 대학생의 혈중 leptin 농도 = The effects of acute exercise with two different intensities on plasma leptin levels in college male 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 8 college male 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 reduced after acute bout exercise with two different intensities (pre>30min=18Qmin (75%), pre>60min (50%), p<0.05). Resting plasma insulin levels were not reduced as a result of acute bout exercise both intensity (p<0.05). Resting plasma glucose levels were significantly increased after acute bout exercise only high intensity (pre<post=15min, p<0.05). Resting plasma FFA levels were significantly increased after acute bout exercise only high intensity (pre<12Qmm=18Qmin, p<0.05) Resting plasma glycerol levels were significantly increased after acute bout exercise with two different intensities (pre<post=15min (75%), pre<15min (50%), p<0.05) 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.
