Study on Cardiovascular Changes in Exercise | Chapter 18 | New Frontiers in Medicine and Medical Research Vol. 11

 Physical activity is the most extreme form of stress that the body is exposed to throughout daily life. The body must make rapid and integrated cellular and organ-system adaptations to fulfil the body's metabolic, thermal, and fluid demands during an acute bout of exercise. Exercise physiology is the study of the physical and chemical processes that allow chemical energy to be converted into mechanical work. Energy is required for both the contraction and relaxation processes in skeletal muscle. Exercise physiology research reveals the regulatory mechanisms that make energy available to skeletal muscles during acute exercise and allow for slower changes during training. The main goal of cardiovascular alterations during exercise is to provide enough oxygenated blood to exercising muscle at a rate that matches their metabolic needs. Cardiovascular reactions help to achieve this. The goal of this study is to see how determinants of heart performance work during exercise.

L-Arginine as a Dietary Supplement and Its Role in Management of Sickle Cell Anaemia and Ischemia | Chapter 2 | Current Research in Agricultural and Food Science Vol.1

Now a day’s problem in health has become more common. So, instead of curing them, prevention
through dietary supplements has proven to be useful. In the case of patients who have already
developed the disease at least relieving pain and suffer is a challenging thing. Arginine reduces the
pain associated by synthesizing NO and causing vasodila-tion of blood vessels in sickle cell anaemia.
Ornithine is converted to citrulline and finally to arginine through certain metabolic reactions like
transamination. Arginine through NO regulates the endothelium of blood vessels and protects against
trauma and ischemia. Arginine supplementation along with antioxidants proved to be useful due to
additional protection offered during ischemia.
