Chocolate milk could be key to longer, healthier life

03.03.2006


The popular saying goes that 70 is the new 60 and 60 is the new 50, unfortunately for much of New Zealand’s ageing population declining muscle function means it simply isn’t true.



New research however from The University of Auckland’s Faculty of Science aims to develop a non-pharmaceutical means to maintain muscle function and quality of life in older individuals. The good news is the answer could be as simple as taking a stroll followed by a glass of chocolate milk.

Senior lecturer at the Department of Sport and Exercise Science, Dr Benjamin Miller, says the goal of his research is not to make athletes out of the elderly, but to increase our lifespan and quality of life in old age.


"The ability of people to create energy and perform work stems from structures that exist inside our cells called mitochondria. As we grow older the amount of mitochondria we have decreases and with it our respiratory capacity.

"This decline is determined by the turnover of proteins in the mitochondria. We hope to highlight an effective and easy way to maintain the protein content in muscles or at least replace old and damaged proteins with new ones."

With funding assistance from the New Zealand Health Research Council, Dr Miller and PhD student Cheryl Murphy, asked a group of elderly kiwis to perform two identical sessions of aerobic exercise on a stationary bike. After one session the participants were asked to drink a mixture of protein and carbohydrate (e.g. sweetened milk) and after the other just carbohydrates.

It is well known that consuming proteins and sugars after resistance training increases the synthesis of proteins used for force i.e. it builds muscles. Dr Miller’s research will tell us whether doing the same after aerobic exercise can also increase the synthesis of mitochondrial proteins which affect our ability to make energy and play a large role in our mortality.

"We know of course that exercise has a wide variety of health benefits, but our research specifically targets mitochondria since they are a cause of age-related decreases in muscle function.

"If successful, we could prove that our non-pharmaceutical means to increase muscle quality could mean that a practice as simple as drinking a Milo after exercise may help reduce our morbidity and prolong mortality."

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....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
