Those who exercise when young have stronger bones when they grow old

03.05.2010
The positive effects of exercise while growing up seem to last longer than previously believed. New findings suggest that physical activity when young increases bone density and size, which may mean a reduced risk of osteoporosis later in life, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

For the thesis, around 3,200 men had their bones examined and their exercise habits mapped. Of these, just over 2,300 18-year-olds were selected at random to have their heel bone examined by the researchers. The heel bone is particularly useful to study as it is directly impacted by exercise, being loaded with the full weight of the body.

“In this group, we found that those who actively did sports, and also those who used to do sports, had greater bone density than those who had never done sports,” explains Martin Nilsson, physiotherapist and doctoral student at the Institute of Medicine.

The researchers also looked at bone density and structure in the lower leg in around 360 19-year-old men who had previously done sports but had now stopped training. They found that men who had stopped training more than six years ago still had larger and thicker bones in the lower leg than those who had never done sports.

“This result is particularly important, because we know that a bone with a large circumference is more durable and resistant to fractures than a narrower bone,” says Nilsson.

The researchers also studied bone density throughout the body in around 500 randomly selected 75-year-old men. Those who had done competitive sports three or more times a week at some point between the ages of 10 and 30 had higher bone density in several parts of the body than those who had not. The researchers have therefore established that there is a positive link between exercise while young and bone density and size. The connection is even stronger if account is taken of the type of sports done.

“The bones respond best when you’re young, and if you train and load them with your own bodyweight during these years, it has a stimulating effect on their development,” says Nilsson. “This may be important for bone strength much later in life too, so reducing the risk of brittle bones.”

OSTEOPOROSIS
Osteoporosis, or brittle bone disease, is very common in Sweden. Osteoporotic fractures affect one in two Swedish women and one in five Swedish men at some point in life. Brittle bones cause 70,000 fractures in Sweden annually, costing the health service almost SEK 5 billion a year. These fractures often result in reduced function and considerable suffering for the patients concerned.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
