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: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
