Do Aerobic Exercise for Top Condition
The heart is a muscular pump, about the size of your fist. It beats non-stop pumping blood throughout the circulatory system. In a typical day, some 2000 gallons of blood will pass through the heart. Like any muscle, the heart needs exercise, or it will deteriorate. So, the reasons for doing aerobic exercise are well-founded.
In the past, bodybuilders built strength and muscle while neglecting the body’s most important muscle: the heart. Conversely, long-distance runners have often concentrated solely on cardiovascular endurance, with little regard for their body strength.
The unprecedented interest in fitness has led athletes in all sports to recognize the value of conditioning. Research and sports physiology have proven the value of all-around training.
If your goal is to be in the best possible condition, why only work on muscular development and neglect the heart and vascular system?
You might look great, but the motor that keeps you alive can be suffering from neglect. A combination of weight and cardiovascular training is ideal.
Do aerobic exercise at least three days a week
Humans can move because of muscular contraction. The muscles use energy to contract in two ways: aerobically and anaerobically.
Aerobic vs. Anaerobic
“with oxygen.” Aerobic exercises are those where the heart can pump blood with enough oxygen to muscles. The heart and lungs supply the oxygen in an amount required by the activity. Typical aerobic exercise is a distance running, cycling, and swimming.
These activities, although strenuous, are rhythmical and performed at less than full intensity. During exercise, there is a brief rest period for the main working muscle group, while another does the work. The blood can bring oxygen and nutrients to the muscle cells and removes metabolic wastes. That allows the movement to continue for an extended period.
“without oxygen.” Anaerobic activities are those where the oxygen demands of the muscles are higher than the circulatory system can supply. The muscles can continue to function for a short time by utilizing a chemical process that free oxygen within the tissue itself. Short duration full in sports like sprinting, and weightlifting are anaerobic exercises.
How does this work?
The oxygen a runner inhales at the start of a 100-meter sprint does not get to the muscle cells until after the race is over. The sprinter uses anaerobic metabolism to run the race. After the dash, the sprinters are gasping for air. They are reloading the oxygen void of the muscles. Oxygen helps remove lactic acid and other products of muscular contraction and replenishes energy stores in the flesh.
Aerobics is a physical exercise made up of a set of rhythmic movements for music with the purpose of improving overall fitness. It improves cardiovascular health, muscular strength, and flexibility. It is usually practiced in groups in a gym and led by an instructor. Although, it can be practiced solitary and without music. The exercise gained worldwide popularity and became trendy after the release of Jane Fonda’s exercise videos in 1982. Masses of people mimicked Jane in front of their TV in the 80′. Aerobics can be divided into two different branches: fitness aerobics and sports aerobics.
