Abstract

 
The aim of this study was to investigate the effect of 8 weeks of aerobic exercise with an ergometer and nettle extract supplementation on plasma levels of nesfatin-1 and C-reactive protein in overweight and obese women. A total of 46 overweight and obese women (age range of 25-45 years, BMI>25 kg/m2) were purposively selected and randomly divided into 4 groups: exercise+nettle (n=12), exercise+placebo (n=12), nettle (n=11), placebo (n=11). The nettle and placebo groups daily received 8 ml of nettle extraction and placebo solution respectively after their mail meal for 8 weeks. Aerobic exercises were conducted for 8 weeks, 3 sessions per week with an intensity of 60-75% of reserved heart rate. Blood samples were collected after 12 hours of fasting and also 48 hours after the exercises in experimental conditions. Nesfatin-1 plasma level significantly increased in exercise+nettle, exercise+placebo and nettle groups after 8 weeks of aerobic exercises and nettle supplementation (P<0.05) and exercise+nettle group had the highest increase. Weight changes, BMI and BF% showed a significant difference in all intervention groups compared to the pretest (P<0.01). Also, plasma level of CRP significantly reduced in exercise+nettle, exercise+placebo and nettle groups (P<0.05). In general, it seems that aerobic exercise on an ergometer as an effective training method with nettle extract supplementation can immunize the body against inflammatory diseases related to obesity through a reduction in CRP inflammatory marker and an increase in plasma levels of nesfatin-1.
