5. Endocrine System Responses to Exercise
Learners who complete Science of Exercise will have an improved physiological understanding of how your body responds to exercise, and will be able to identify behaviors, choices, and environments that impact your health and training. Active learning assessments will challenge you to apply this new knowledge via nutrition logs, heart rate monitoring, calculations of your total daily caloric expenditure and body mass index BMI. Finally, learners will examine the scientific evidence for the health benefits of exercise including the prevention and treatment of heart disease, diabetes, cancer, obesity weight loss , depression, and dementia. It was an excellent experience and I have learned a lot. It helped me to understand my body even better, especially since I am regularly exercising as well. I can highly recommend it. This course is very well designed.
Glucocorticoids, such as cortisol, are steroid hormones produced by the zona fasciculata of the adrenal cortex in the adrenal gland. Regrettably, misconceptions regarding the physiological actions of these hormones in particular relative to the catabolism have been created within the areas of sports and exercise. For example, cortisol most often is viewed as having a counter-productive role in exercise that can lead to a mal-adaptation to the exercise training process, due to the catabolic nature of this hormone relative to protein turnover. Therefore, the intent of this article is to present an overview and to offer remarks on the necessary and critically important functions of glucocorticoids during exercise, and in the adaptation process associated with exercise training. The emphasis is specifically to correct several of the misconceptions and misunderstandings that are portrayed within some research and popular literature regarding endocrine responses to exercise and exercise training. Stress has been a research topic for over years and historically, the paramount early leader in the study of stress was Hans Selye. This theory proposes an intimate involvement of the adrenal gland, specifically the cortex, in the adaptation and mal-adaptation process to all forms of stress.
Exercise is physical stress applied to the human body. The endocrine system consists of glands that release the chemicals and hormones that control physiological functions in the body. Do you know which hormones are responsible for muscle growth vs. Are you proficient in designing safe and effective exercise programs that maximize muscle growth and fat utilization based on hormonal response to training stimuli? Knowing the answers to these questions is key to your training success with clients. This know-how also greatly enhances your credibility with clients and your employer. Here is a quick overview of the endocrine system: Pituitary Gland During exercise, the pituitary gland releases human growth hormone, which tells the body to increase bone, muscle and tissue production.
This valuable new addition to the Encyclopaedia of Sports Medicine series provides a comprehensive and logical look at the principles and.

The endocrine system is made up of glands that make hormones. Hormones are the body's chemical messengers. They carry information and instructions from one set of cells to another. The endocrine EN-duh-krin system influences almost every cell, organ, and function of our bodies. Too much or too little of any hormone can harm the body. Medicines can treat many of these problems.
