Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 12
Abstract
Obestatin is a 23-Amino Acid peptide which secreted from the fundus of stomach and can play an important role in regulation of food receiving and body weight. The aim of the present study was to investigate the Effect of moderate and high intensity aerobic exercise training on plasma levels of obestatin in male wistar rats. Nineteen male Wistar rats (8 weeks old, 200 to 225 g) randomly divided to control and training. After two weeks of familiarization speed and time gradually increased to determined intensity for each group. Aerobic training program included 8 weeks, 5 sessions per week for 60 min. the intensity of the exercise was 80% - 85% VO2max for high intensity training group (HIT group) and 70% - 75% VO2max for moderate intensity training group (MIT group). Rats were anesthetized intraperitoneally fourty-eight hours after the final training session (after 12 h fasting), and Blood samples was collected directly from the right ventricle. The mean weight in HIT group reduced significantly than to control group. Plasma obestatin levels didn’t have any significant differences between these three groups. However the obestatin levels in Exercise training groups were higher than control group.
