We can define the Aerobic as a type of exercise that stimulates the cardiovascular and respiratory activity during a certain time in our body to produce a series of achievements. In general terms, is the ability to maintain effective effort as long as possible, not less than three minutes.
The definition of Aerobics in particular, are based on a series of structured and logically sequenced exercise techniques, accompanied by musical rhythms in order to achieve a cardiovascular improvement. The Aerobic increases and develops muscular endurance, speed, flexibility, coordination, agility and relaxation.
Differences between a sedentary person and practicing the Aerobic
- Bigger heart, with more weight, volume and strength in their myocardium, which allows you beat with less effort and frequency, while more blood ejected at each systole.
- More capillaries, up to 45% more than in sedentary
- Increased elasticity of the blood vessels, and thus better blood line
- More red blood cells, which sometimes exceed five million in the clinical counting.
- More hemoglobin. It is noted that often, athletes spend 90% of this compound, which has the important function of transporting oxygen to tissues and remove carbon dioxide from these.
- Increased ability to maintain blood pH within individual limits. as we know, this alkaline substance is responsible for neutralizing acid metabolism during the characteristic means and constant efforts of most sports association. Increased capacity in relation to blood pH allows greater oxygen debt, which enables higher yields in media efforts and constant referrals.
- Less fat and fatty substances in the blood. All this comes together to bring more oxygen and nutrients to cells and remove waste products of metabolism materials, which means more resistance.
Respiratory system of a aerobic body
- Respiratory muscle hypertrophy with increased efficiency in inspiration and expiration.
- More powerful and bulky lungs. More vital capacity. Generally, the vital capacity of a subject sedentary lifestyle is 3.5 liters (maximum capacity of air that can inspire a subject from the maximum expiration), while athletes can exceed 4 liters and sometimes up to 5.
- More working alveoli.
- More capillaries and lung alveoli. All this together results in improved hemostasis more releases carbon dioxide and increased oxygen uptake, which improves the resistance.
Muscular System – Articular
- Thickening of the muscle fiber that strengthens and its membrane and around the muscle. Overall, less fat and muscle hypertrophy.
- Strengthening tendons and ligaments.
- Improving the elasticity of muscles and tendons.
- All this together, improves muscle contraction and joint movement, which results in more force.
Nervous system from a aerobic body
- Increased influence of the parasympathetic nervous system on the heart and circulation, respiration, metabolism, excretory system and depth of sleep.
- Faster central nervous system to receive a perception, transforming it into a motor command, and carry nerve impulses (motor command) to the muscles.
- All this comes together to enhance the reaction rate and displacement and to save energy in automatic gestures.
Metabolism with Aerobic
- Increased metabolism, cheaper with good energy reserves and rapid use of them.
- For these morphological and functional differences product of methodical long-term training, the athlete is stronger, powerful, strong, flexible and fast.
- The differences may vary by training this more oriented development and improvement of quality either. For example, a more oriented strength training increases the differences in one direction, while one that is more focused on endurance, will on another.
Aerobic: Origin and History
The origins of Aerobic as we understand it today, we can put them in 1968. In this year, was published for the first time in America a book entitled “Aerobics“. Its author, Dr. Kenneth H. Cooper, doctor of the US Air Force, work out in the training program that he designed for members of the Air Forces of his country.
The program consisted in carrying out efforts for extended periods of time, in order to increase the performance and endurance of those who performed, thus decreasing the risk of developing heart and circulatory diseases.
From this initial program, created by the one who is regarded as the “Father of Aerobics” appeared first in America and then in other countries, fashion Jogging a more popular way of practicing aerobic endurance training .
Over the years, he thought about the possibility of combining music and elements from different disciplines: jogging, jazz, gymnastics, dancing … and create something new. The result is what we know and call as Aerobic Dance, which is to follow a series of many steps or ballistic movements, which are the delight of those who practice it.
