”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:

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.
The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.
At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.
Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.
If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
