The Effects of Exercise Indensity on plasma leptin concentration in exercise recovery
ABSTRACT
The Effects of Exercise Indensity on plasma leptin concentration in exercise recovery. Exercise Science, 13(1): 35-42, 2004. leptin is an adipocyte-derived hormone that has been shown to regulate body weight and thermogenesis in human and animal (Kraemer et al, 2000). The objective of this study was to investigate the effects of exercise intensity on plasma leptin responses. The 8 college male students were participated in acute bout exercise with two different intensities; 50% (LT) and 75% (HT) of maximal oxygen consumption. The energy expenditure was equal to both intensity (≒ 250 kcal). Plasma leptin levels were significantly reduced after HT (pre > 120 min> 180 min), but there was no significant difference between HT and LT. EPOC were significantly increased after acute bout exercise with two different intensity, and HT was higher than LT. Plasma insulin levels were not significantly changed in two groups. Plasma FFA levels were significantly increased after acute bout exercise only HT (p<.05). Plasma glycerol levels were significantly increased after acute bout exercise with two different intensities (p<.05). Plasma glucose levels were significantly increased after acute bout exercise only HT (pre<post, 15min, p<.05). Plasma lactate levels were significantly increased after acute bout exercise with two intensity group, and HT was higher than LT. These data indicate that high intensity exercise did significantly affect plasma leptin levels during the 3h-recovery.
Key words: Leptin, Exercise Intensity, EPOC.
