Over 100 healthy but sedentary civil servants between the ages of 40 and 60 took part in the study, which involved adopting an exercise programme for 12 weeks, with no changes in diet.
The group was divided into three, with one group assigned 30 minutes of brisk walking for five days a week, another group 30 minutes of brisk walking for three days a week and the remainder were not asked to change their current lifestyle.
Pedometers were used to help participants monitor their walking and every participant recorded how long they walked for.
Dr Mark Tully, from the Health and Rehabilitation Sciences Research Institute at UU said: “We recorded blood pressure, blood cholesterol, weight, hip and waist girth, and overall fitness at the start and finish of the 12-week study.
“Our findings showed that systolic blood pressure and waist and hip girth fell significantly in both groups of walkers. Overall fitness also increased.
“Falls of a few millimetres in blood pressure and shrinkage of a few centimetres in hip and waist circumference are enough to make a difference to an individual’s risk of dying from a cardiovascular disease.
“Furthermore, the findings show that moderate intensity physical exercise below the recommended levels (30 minutes of moderately strenuous exercise on at least five days of the week), still makes a difference to health.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
