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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
