Over the course of seven weeks, runners were able to improve performance on a 1500-metre run by 23 seconds and almost by a minute on a 5-km run – and this despite a 50 per cent reduction in their total amount of training.
These are just some of the results from a research project involving 18 moderately trained runners following the 10-20-30 training concept developed by researchers from the Department of Exercise and Sport Sciences at the University of Copenhagen.
In addition to enhancing running performance, the runners from the project also had a significant decrease in blood pressure and a reduction in cholesterol in the blood.
"We were very surprised to see such an improvement in the health profile considering that the participants have been running for several years," says Professor Jens Bangsbo, Department of Exercise and Sport Sciences, who heads the project.
"The results show that the very intense training has a great potential for improving health status of already trained individuals," says Professor Bangsbo.
PhD student Thomas Gunnarsson adds that the emotional well-being of the participants also improved over the span of the project.
"We found a reduction in emotional stress when compared to control subjects continuing their normal training based on a recovery-stress questionnaire administered before and after the 7-week training period," explains Gunnarsson.
The 10-20-30 training concept
The 10-20-30 training concept consists of a 1-km warm-up at a low intensity followed by 3-4 blocks of 5 minutes running interspersed by 2 minutes of rest. Each block consists of 5 consecutive 1-minute intervals divided into 30, 20 and 10 seconds of running at a low, moderate and near maximal intensity, respectively.
30 minutes is all you need
According to Professor Bangsbo, the 10-20-30 training concept is easily adapted in a busy daily schedule as the time needed for training is low. A total of 20-30 minutes including warm-up is all that is needed. Since the 10-20-30 concept deals with relative speeds and includes low speed running and 2-minute rest periods, individuals with different fitness levels and training backgrounds can perform the 10-20-30 training together.
"The training was very inspiring. I could not wait to get out and run together with the others. Today, I am running much faster than I ever thought possible," says Katrine Dahl, one of the participants in the study.
The study was supported by the Nordea-fonden, Copenhagen, Denmark, and the results are published in the Journal of Applied of Physiology.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
