”We do not yet know for sure what the causal relationship between physical activity and depression is like. What is clear is that elderly people who are physically active are less depressed, but higher levels of depression can also lead to less exercise, and this suggests there is a mutual influence," says Magnus Lindwall, docent (associate professor) in exercise and health psychology at the University of Gothenburg.
In a recently published study Lindwall, together with research colleagues, has studied 17,500 elderly people with an average age of 64 from 11 European countries who are taking part in the large EU-funded population study Survey of Health, Ageing and Retirement (SHARE). The subjects in the study were followed up over a period of two and a half years, among other things with regard to physical activity and depression.
“This study is one of the first to look at both how physical activity affects future depression and vice-versa, and how change in physical activity is associated with change in depression over time,” says Lindwall.
”An important question for the researchers to answer has been what motivates elderly people to be physically active. Modern motivational theories propose, for example, that individuals who feel that they are competent, that they can take decisions for themselves and have freedom of choice and that they feel social relatedness linked to physical activity experience a more internal and a less controlled form of motivation for exercise. . This form of motivation, unlike a non-self-determining external form of motivation, is also associated with the maintenance of long-term regular physical activity, which also improves the prospects for the positive effects that physical activity can have on both physical and mental health.
"Right now we are developing and testing a structured programme to increase motivation for physical activity among the elderly based on the theories that today has strong support in the research," says Lindwall.
The results support the recommendations to use physical activity as a powerful preventive measure against mental ill-health in the elderly.
”But regular physical activity is required, otherwise there is a great risk of the long-term favourable effects on health being lost. It is therefore important to identify the barriers, for example depression, that prevent the elderly from being physically active and focus on how to increase the motivation of elderly people for physical activity," says Lindwall.Bibliographic data:

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...
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...
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,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
