Rock hard workouts

09.11.2006
Physical activity can help reduce women’s risk of developing osteoporosis. But taking a stroll simply isn’t enough.

Norwegian women top osteoporosis statistics in Europe. They are four times more likely to break their hips than their Italian counterparts, and their risk is double that of American women.

It is a known fact that being physically active reduces the risk of developing osteoporosis. The Norwegian Institute of Public Health recommends 30-minute walks two or three times a week. The idea is that even moderate physical activity will help prevent osteoporosis.

INTENSIVE TRAINING

However, NTNU researchers have data that suggests that a moderate activity level simply isn’t enough to prevent osteoporosis. Researchers have based their conclusions on data from 1400 women who are participants in the Nord-Trøndelag Health Study (HUNT).

“One of the factors we looked into was the relationship between physical activity and a measurement called BMD among healthy women aged 20 to 44”, explains Associate Professor Liv Berit Augestad.

BMD stands for “bone mass density”, and is a measure of the density of skeletal bone cells. Samples were taken from the forearm. Physical activity was measured according to frequency, rate, and intensity of the activity. Unfortunately, the HUNT data did not include information about the nature of the activities.

“We found that the small group of women who reported the highest level of physical activity also had the highest BMD”, Augestad says.

DON’T WALK – RUN!

Physical activity can involve both weight-bearing exercises and conditioning. Augestad stresses that we do not know enough yet to determine which training method gives the best outcome. And we do not know how often and how intense the training should be.

“But what we do know is that casual walks and other light forms of physical activity are not sufficient if you want to prevent osteoporosis. Both intensive aerobic exercise and weight bearing exercise are good methods”, she says.

She adds that Americans have already realised the need for a more intensive exercise regime: the CDC (the Centers for Disease Control and Prevention), the American equivalent of the Norwegian Institute for Public Health, recommends that Americans include daily physical activity in their lives to reduce the risk of different diseases, including osteoporosis.

START AT AN EARLY AGE

The study suggests that the greatest effect of physical activity on developing a strong and healthy skeleton is achieved between the ages 15 and 30.

“But physical activity may also help reduce of the speed of bone cell reduction later in life. Thus it is never too late to start”,Augestad says.

The study was conducted by Augestad with Professor Berit Schei, Siri Forsmo, Arnulf Langhammer, and Professor Dana Flanders.

Im Focus: Frictional Heat Powers Hydrothermal Activity on Enceladus

Computer simulation shows how the icy moon heats water in a porous rock core

Heat from the friction of rocks caused by tidal forces could be the “engine” for the hydrothermal activity on Saturn's moon Enceladus. This presupposes that...

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
