Most types of exercise can be either aerobic or anaerobic. The level of intensity determines whether you are using your aerobic or anaerobic system.
Walking, jogging,running,biking, swimming,dancing etc. can provide either benefit. Lower heart rates make these activities aerobic, and higher heart rates make them anaerobic... Usually, tennis, racquetball, basketball, and similar sports are anaerobic.
Most Americans have a lifestyle that causes them to live in a constantly anaerobic state, inundated with stress and demands, compounding it with the way they choose to exercise. As a result they train their metabolism continuously with anaerobic, i.e. burn glycogen as a primary source of energy. When the levels of glycogen become excessively low, the anerobically trained metabolism turns to blood sugar as its secondary source of fuel. This immediately disrupts your level of health and vitality.
As your anaerobic demands rob your body of blood sugar you could be using for other tasks,you immediately begin to feel negative effects. Since your nervous system demands the use of two-thirds of your blood sugar, the deficit created by anaerobic exercise that cause neuromuscular problems like headaches or disorientation. Here is a list of some telltale symptoms directly related to excessive anaerobic training of your metabolism : fatigue, recurrent exercise injuries, low blood sugar patterns, depression and anxiety, fat metabolism problems, premenstrual syndrome, or circulation problems and stiff joints.
We live in a society that is anaerobic - excessive and aerobic -deficient, and it's negatively impacting the quality of health across the nation. In modern, industrialized society, people become less physically active. Only a few decades ago, most of the people accomplished their daily chores in a physical way. Today, though, we have designed active demands for our bodies to replace the inactivity that our day-to-day life no longer creates. This forced activity we call exercise. Unfortunately, many people with positive intentions, including skilled athletes, are becoming less healthy with exercise. Out of our drive to produce the greatest results in the shortest period of time, most of us create an improper balance between health and fitness, and suffer the consequences....
