Abstract
Introduction: Yoga is an ancient activity designated to both health and unhealthy individuals. It integrates physical, mental, and spiritual components and may improve aspects of health. Yoga regulates various body systems such as the endocrine system. Serotonin is an effective mono-amine neurotransmitter in controlling emotions and Appetite. The purpose of this study was to investigate the effect of eight weeks of selected yoga exercises on plasma levels of serotonin and appetite index in non-athlete obese women.
Methodology: In this quasi-experimental research with pretest-post test design, twenty non-athlete obese women with body mass index (BMI) ≥30 and aged 30-40 years old volunteered to participate in the present study. Before exercise intervention, the subjects were divided randomly into two equal groups of control (regular life) and experimental (yoga exercises). The experimental group did eight-week selected yoga exercises, three sessions per week and each session lasting 60-75 minutes. Before and after intervention, blood samples were collected from all participants from Cubital vein at 12 hours fasting state. Plasma levels of serotonin and appetite index were assayed using ELISA methods and appetite index questionnaire, respectively. Data were analyzed using paired t-test and ANCOVA (P<0.05).
Results: Results showed that eight weeks Yoga exercises lead to significant increases in plasma levels of serotonin (P<0.05) and appetite index improved significantly in non-athlete obese women (P<0.05).
Discussion: In conclusion it seems that doing yoga exercises probably can be effective in improvement of some physiological indices related to appetite in non-athlete obese women. Also, considering some psycho-physiological aspects of obesity may be helpful in achieving an appropriate strategy for treatment of obesity.
