Calcium is certainly one of the most important elements of the human body. Calcium is necessary for the transmission of nerve impulses, blood clotting, secretory activity, cell differentiation and death, the implementation of the immune response, some enzymatic processes, the process of muscle contraction, etc. The concentration of calcium in the blood can vary by no more than 3% and is subject to strict control by the homeostasis system, and is also regulated by the hormonal system.
The level of calcium in the blood is regulated by two hormones, as well as calcitriol. In addition, the level of calcium in the blood can change under the influence of heavy metals. The process of calcium absorption and the processes of its removal from the body are influenced by many factors - the state of the hormonal system, the quality of food, the intensity of the training process, etc. At the same time, uncontrolled consumption of calcium by athletes entails extremely negative consequences.
Keywords
