Danish research under microgravity show that it is good for the circuit to travel to Mars, and that sedentary work on Earth causes high blood pressure. But it is difficult to carry out experiments in weightlessness. By Mette Jensen Buck 18 , 2010 at. 10:00
The Danish professor of rumfysiologi University of Copenhagen, Peter Norsk conducted many experiments on the European Space Agency ESA's parabolic flights with a flight where passengers experience weightlessness in 20-22 seconds wic jobs in texas at a time.
With experiments on Dish flights, wic jobs in texas his research team looked at what the acute phase weightless means of how much blood the heart pumps out to the body and how blood pressure is regulated. This is part of a larger project in which the astronauts on the International Space Station measuring the same thing after a long stay in space and thus long-term absence of gravity.
The experiments not only explains how weightlessness affects astronauts' cardiovascular system, but also the daily exposure to gravity - so-called gravitational stress - mean to us on Earth. For the removal of one factor, one can see the effect of it.
"Blood pressure is higher when you are on the ground wic jobs in texas where there is gravity. And when we sit quietly and work, as we do in modern society today, unlike earlier, the gravitational stress on the circuit stronger because hydrostatikken. This means that you get a higher and higher blood pressure over time the more you work sedentary, "says Peter Norwegian. No help to the heart at the desk
Together Pulling muscles terminals namely else along the body's veins and helping to push blood back to the heart. Sitting causes the heart no help and must therefore work harder. And the blood shall even work against gravity up to the heart.
'The results from the experiments in microgravity says that gravitational stress at the sedentary work in modern society is a factor in that we get more and more with high blood pressure. If you go around blood pressure is lower when you are sitting still is higher. And you would really wic jobs in texas have thought that it would be reversed, wic jobs in texas "said Peter Norsk continues:
"If we had not been able to make parabolic flights we would not have seen it that way. Weightless catering Research is in general a control experiment in terms of what is happening wic jobs in texas on Earth. "Weightlessness = lower blood pressure
During the 20-22 seconds each sequence of weightlessness items on Dish flight, measuring research team cardiac output. That is, how much blood the heart pumps out to the body. By comparing this with the blood pressure in the heart level, they can calculate the resistance of the circuit using Ohm's law. It gives a measure of how contracted and stressed blood vessels.
"After three or four months in space, you have significantly lower blood pressure than on Earth - it means that you have taken a blood pressure-lowering medication. It is actually beneficial and I would say that it is good for the circuit to take back and forth to Mars, since it enables the blood pressure down. The low blood pressure because blood flows more easily around the body and the blood vessels is relaxed. It was not known before we performed these experiments. 'Challenges of experiments in microgravity wic jobs in texas
A new project his team is about to send in the air to look at the influence of one's height has on blood pressure during weightlessness. The researchers concerned to reveal that tall people have higher blood pressure than others here on Earth.
Peter Norwegian Professor of Biomedical Sciences, University of Copenhagen, where he conducts research wic jobs in texas into cardiovascular physiology as well as gravity wic jobs in texas and rumfysiologi. He played a significant wic jobs in texas role in the selection of Danish astronaut wic jobs in texas candidates for ESA.
He's from New Year got a new job at NASA Johnson wic jobs in texas Space Center in Houston, wic jobs in texas Texas in the United States, where he will be chief scientist of "the human health and countermeasure" wic jobs in texas program that deals with how to thwart antigravitation negative effects on human bodies. wic jobs in texas Weightless flight
The engineer took part in the European Space Agency wic jobs in texas ESA 53 Dish campaign where a plane diving toward the earth, so are experienced 0 G - weightlessness on board. The campaign was carried out three days in a row in October from Bordeaux airport and took on an Airbus 300 Zero-G, owned by NOVESPACE in charge of the execution wic jobs in texas of the campaign. The engineer took part in the second of the campaign's three flights.
