The effect of aerobic exercise in terms of irisin on some physiological variables of weight loss for females aged (40-45) years

Abstract

The middle age stage is one of the difficult stages that women go through as a transitional stage, as they are subject to many hormonal and physiological changes, which makes them more susceptible to diseases. Therefore, the practice of physical effort is a helping factor in mitigation to overcome this stage and the accompanying changes to gain a harmonious body and an ideal body composition. The interest in physical fitness came as a result of inactivity, so it became necessary to practice a type of multiple physical exercises, such as aerobic exercises, as they fall within the therapeutic exercises for many diseases of the heart, joints, and arteries. It is practiced by society groups, especially women at this stage of life, as it is characterized by simplicity, fun, fun and safety, in addition to its main work in helping to lose weight and maintain a fit and graceful body, and it is known that the performance of any physical effort is accompanied by a change in physiological processes as a response For the changes that occurred, among these changes are the levels of hormone secretion, especially the hormone irisin. Moon we can determine the activity of cellular metabolism when there is a rise in the level of the hormone, which is a result of the rise in metabolic processes and thus an increase in the transformation of fat cells, and this in turn leads to weight loss. As for the research problem, it lies through answering the following question: Do women who have an increase in the hormone irisin respond properly Better for aerobic exercises than those with lower levels of activity? The researchers used the experimental method in the one-group method to suit it to solve the research problem. The research community and sample were identified, which are women participating in fitness halls in Al-Diwaniyah Governorate, whose ages range from 40-45 years.
