Steroids
Steroids Many people have had their lives ruined by the use of illegal steroids, yet the desired effects are so overwhelming that people tend to overlook the consequences. Steroid users believe taking anabolic steroids will enhance their performance, strength, size,etc. They regard the use of them as legitimate as any other aspect of training. To begin with, the term anabolic means to build tissue, therefore anabolic steroids tend to increase constructive metabolic pathways within the body. Also

Drug Dependence
Drug Dependence
Drug Dependence In order for a chemical to be considered a drug it must have the capacity to affect how the body works--to be biologically active. No substance that has the power to do this is completely safe, and drugs are approved only after they demonstrate that they are relatively safe when used as directed, and when the benefits outweigh their risks. Thus, some very dangerous drugs are approved because they are necessary to treat serious illness. Digitalis, which causes the heart muscle to

Cardiovascular Condition Cardiovascular conditioning can be defined as the efficient transport and utilization of necessary oxygen and nutrients to the tissues of the body. The cardiovascular system needs to be well conditioned to enable the body to deliver adequate oxygenated blood and nutrients to the working muscles, in addition to improving the muscles’ capacity to use extra oxygen. Cardiovascular training is the most important style of training both for general health and for overall athlet

Lung cancer was first described by doctors in the mid 1800\'s. At the turn of the century, it was still considered a rarity; that has changed dramatically. What has not changed is the difficultly of detecting lung cancer in its earliest stages when it has the greatest chance

Cancer I. Cancer is a group of diseases characterized by an uncontrolled growth of abnormal cells. If the spread of these abnormal cells is not controlled, cancer can cause death. Most cancers take the form of tumors, although not all tumors are cancers. A tumor is simply a mass of new tissue that serves no physiological purpose. It can be benign, like a wart, or malignant, like cancer. Benign tumors are made up of cells similar to the surrounding normal cells and are enclosed in a membrane that

The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body\'s ability to provide adequate oxygen to be utili

Arthritis Osteoarthritis is a degenerative arthritis, a condition in which joint cartilage degenerates or breaks down. New tissue, which grows at the ends of bones, now has no cartilage cap to control it. Instead, this new bone forms into strange lips and spurs that grind and grate and get in the way of movement of the joint. Osteoarthritis is common in older people after years of wear-and-tear that thin the cartilage and the bones. Osteoarthritis can also result from diseases in which there is

Fluids and Hydration How important are fluids? Fluid replacement is probably the most important nutritional concern for athletes. Approximately 60% of your body weight is water. As you exercise, fluid is lost through your skin as sweat and through your lungs when you breathe. If this fluid is not replaced at regular intervals during exercise, you can become dehydrated. When you are dehydrated, you have a smaller volume of blood circulating through your body. Consequently, the amount of blood you
