The Need For Aerobics
Aerobics had been a worldwide phenomenon since the 80s, and most of the world knows about it. For the uninitiated, Dr. Kenneth Cooper (its developer) submitted the official definition to the Oxford English Dictionary.
Accordingly, aerobics is defined as “a method of physical exercise for producing beneficial changes in the respiratory and circulatory systems by activities which require meeting a modest increase of oxygen intake and so can be maintained.”
Because of today’s many new illnesses (hypertension, type 2 diabetes, and other cardiovascular conditions) brought about by modern man’s generally inactive physical lifestyle, experts strongly recommend aerobics for everyone.
The common definition of aerobics is simply the activity that consists of low-intensity repetitive motions of mostly the large muscles of the arms and legs for a period of time. This activity increases breathing and heart rate.
Most low-intensity activities you do during the day also fall under this category. It includes such regular activities as walking, jogging, swimming, and cycling.
For individuals who are beginners in exercise programs, or maybe have histories of health conditions, light exercise routines are recommended at first on most days of the week.
Experts advise that these aerobic exercises have to be performed at moderate intensity. This level of activity is safe for almost everyone, and it still provides the desired health benefits.
Recent research brings in additional good news. It is revealed that aerobics performers can still have cardiovascular benefits even if the exercise routine (usually 30 minutes total) is broken into three or four 8-10 minute segments, as long as they are of the same intensity.
Doctors, however, discourage infrequent bouts of high-intensity aerobics routines. It is found that this approach is not very healthy.
In the first place, reduction in risks of hypertension, high cholesterol, type 2 diabetes and other conditions depends on the total volume of the exercise done, rather than on intensity.
Higher intensity exercise activities raise your chances for muscle or joint injury. Worse, it may trigger fatal consequences because of heart rhythm disturbances.
Aerobics instructors always begin their sessions with light stretching and low-intensity movements for about 5 to 10 minutes. This warm-up routine is important to avoid injury. At the end of the routine, a similar cooling-down period for about 5 to 10 minutes is also done.
As had been proven these years, people who engaged in regular aerobics have been known to benefit by way of lower blood cholesterol counts, lower blood pressure, toned body because of fat reduction and beneficial weight loss.
They have been known to have developed muscular and overall body endurance, have a happier disposition and moods, and a medically-certified general lower risk to cardiovascular diseases.
