Blood Circulation in Reboundology

How is oxygen transport to working muscles increased in response to the challenge of mild to maximal rebounding aerobics? How is oxygen transport maintained when rebounding is prolonged and demands on the cardiovascular system for heat transport from the muscles are gradually superimposed? These are questions which might be considered when the purchaser of a rebound unit compares his new exercising device to the competition of other ways to exercise.

Once oxygen is absorbed into the red blood cells in the pulmonary circulation, the transport to working muscles is increased by increasing cardiac output and arteriovenous (a-v) oxygen difference. The circulatory response to rebounding is a function of age, sex, posture, and the muscle mass of an individual. The a-v maximum oxygen extraction to nourish the muscle cells is 85 to 90 percent. That's the most oxygen you can get from your blood with the greatest exercise effort, for any exercise movement. This is the exact amount of oxygen extraction achieved with forty minutes of rebounding aerobics performed at the fastest speed by an athlete with very high maximal oxygen uptake (V02).6

Heat transport from the moving muscles is maintained by sacrificing the blood flow to the splanchnic region of the body. The splanchnic takes in the visceraor gut comprising the contents of the abdominal cavity. The splanchnic region normally receives 20 to 25 percent of the total cardiac output at rest, but during exercise the blood flow is shunted away from this area. Up to 400 milliliters of oxygen per minute can be redistributed from the splanchnic region to actively working muscle without any additional increase in cardiac output.7 This is a main reason why you should not ingest food before engaging in rebounding aerobics. There is very little blood flow to nourish the organs of digestion and even less to assist in the process of absorption.

Moreover, blood flow to the skin, as with visceral organs, may be progressively comprised with increasing demands for oxygen transport to the muscles. A person with a weak heart will actually stop the skin blood flow in an effort to supply sufficient blood flow to actively working muscles.

In comparison with other exercises that have a person planting his feet on the ground (except swimming), rebounding aerobics provides a more favorable advantage to the exerciser. That is, the effects of gravity are eliminated and central circulatory changes are less.8 Learn more quickly than others, especially after they come off the rebounding apparatus. They show significantly better results on more difficult puzzles, possibly because of improved memory and learning ability.

Finally, rebounding aerobics offers spiritual inspiration and peace of mind with the universe. You will notice a reduction in your nervousness, aggression, emotional instability, self criticism and self doubt, inhibition, irritability, and depression.

You'll witness an increase in your sense of freedom, self assuredness and self confidence, good humor, positive thinking, staying power and efficiency, sociability, liveliness, tolerance in frustrating situations, harmony with others, respect for others, cordiality, friendliness, effectiveness in persuading others, and an inner contentment.

For those who must confront their addiction to tranquilizers, stimulants, and other drugs, rebounding aerobics provides part of the antidote to removing them from one's lifestyle. It does this by improving the sense of well being, strengthening mental health and thereby directly removing the need for drugs.
