Aerobics: What Is It And When Did It Start? by Andy Guides Jr


Aerobics is a combination of physical exercise, strength training and stretching. Thirty to sixty minutes is the amount of exercise recommended by the American College of Sports Medicine.

Not only is aerobic activity important in controlling body weight, there are an abundant health benefits that come with exercise.

Aerobic fitness can help to maintain good blood pressure levels, allows the heart to pump more effectively, decreases bad cholesterol while improving the good, and by reducing the systemic inflammation can lower the chance of having heart disease.

Another benefit of exercise in people with Type 2 diabetes is that it makes the efficiency of the body better by increasing tissue sensitivity to insulin. In addition, more glucose is produced and pressed out of the blood stream. The blood will enter the cells and decrease the amount of glucose in the blood. By allowing glucose to metabolize in the body and letting normal blood sugar levels be maintained, aerobic exercise minimizes the risk of developing diabetes.

Obesity, which is a big concern in the United States is the first noticeable health benefit of exercise. Any amount of increased activity will bring about a change in the body, including a decrease in body fat and an increase in lean muscle.

Aerobics also helps with the over all quality of life by improving sleep, reducing fatigue, increasing energy levels, improving mood, reducing depression, stress and anxiety. It increases endorphins, which make the outlook on life more positive, prevents certain cancers and may help to increase longevity all while being happier.

Reaching a target heart rate is key to benefiting the most from aerobics. Using the age method, age is taken away from 220, then that number is multiplied by 0.7. The American Heart Association recommends a target heart rate range of between 50% and 75%t. Because people exercise at different fitness levels, this method may not be completely accurate but it does give a number to work toward.

In 1968, Dr. Kenneth Cooper developed a series of exercises listed in his book, Aerobics, that he knew would help to prevent coronary artery disease. These exercises were running, bicycling, swimming and walking.

Aerobic dance came about shortly after Dr. Coopers book was published, by a woman named Jackie Sorenson. She developed dance routines that were found to improve cardiovascular fitness.

In 1983, Howard and Karen Schwartz developed sportaerobics. In 1984 the first national aerobic championship was organized, and in 2002 the competition consisted of 6 athletes performing a 1 minute 45 second routine done to music. The judges based their score of up to 10 points each on artistic and technical merit. In 1996 sportaerobics was changed to gymnastique discipline.

Aerobic activity is an important part of maintaining good health and having a happier, fuller and longer life.
