The software provides instant, in-depth feedback on a swimmer’s glide technique. Swimmers glide following starts and turns, when a swimmer is not moving their arms or legs but is just using their momentum to travel through the water. As well as supplying data on head position, body posture/alignment etc, the software actively suggests ways a swimmer can improve their posture to minimise resistance and pinpoints the optimum moment to begin kicking.
The new system offers two key benefits beyond the capabilities of any other currently used in elite swimming training. First, the feedback it generates is available immediately, so swimmers and coaches can use it at the poolside and implement its recommendations while a training session is still in progress; this will speed up the whole process involved in improving glide technique. Second, it generates data of unprecedented quality in terms of detail and accuracy.
Ultimately, the result will be faster times in races. Gliding more efficiently, with less ‘drag’, can cut vital fractions of a second from a swimmer’s time. The difference between winning an Olympic title and finishing out of the medals is often measured in hundredths of a second, so this innovative software could give British swimmers a valuable edge in their quest for glory.
The software is being developed by sports scientists at the University of Edinburgh’s Centre for Aquatics Research and Education (CARE) with additional input from Sheffield Hallam University, and funding from the Engineering and Physical Sciences Research Council (EPSRC) in collaboration with UKSPORT. Once tested and validated, it should be available to swimmers throughout the UK within around 12 months.
First, the swimmer is marked at their body joints using water-resistant markers. The swimmer is then videoed in action using underwater and poolside cameras, with the images fed into a computer equipped with the software. The software tracks the movements of the markers and runs the digitised position data through an innovative, highly sophisticated mathematical model developed at the University of Edinburgh by Dr Roozbeh Naemi. A replay of the swim then instantly appears on a plasma screen at the poolside, overwritten with graphs and data on different technical aspects of the glide.
“Both the speed and accuracy of the feedback will add to the value of the advice that coaches give their swimmers,” says Professor Ross Sanders, who is leading the project. “Another important benefit is that the alterations to technique suggested by the software are customised exactly to suit each individual swimmer.”
Swimmers from the prestigious City of Edinburgh and Warrender swimming clubs will participate in testing the new system and then in experiments to learn more about the factors relating to gliding performance.
“The software could even help to identify the champions of tomorrow,” Professor Sanders adds. “It will show which young swimmers naturally move easily through the water, which may well equate to outstanding ability or a particular aptitude for the sport.”

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...
