Virtual workout partners spur better results

Researcher analyzes Kohler effect in health video games

Can't find anyone to exercise with? Don't despair: New research from Michigan State University reveals working out with a virtual partner improves motivation during exercise.

The study led by Deborah Feltz, chairperson of MSU's Department of Kinesiology, is the first to investigate the Kohler effect on motivation in health video games; that phenomenon explains why inferior team members perform better in a group than they would by themselves.

The research, to be published in an upcoming edition of the Journal of Sport and Exercise Psychology, was funded by a $150,000 grant from Health Games Research, a national program of the Robert Wood Johnson Foundation's Pioneer Portfolio.

"Our results suggest working out with virtually present, superior partners can improve motivation on exercise game tasks," Feltz said. "These findings provide a starting point to test additional features that have the potential to improve motivational gains in health video games."

By incorporating design features based on the Kohler effect, health video games could motivate vigorous exercise, she added.

"One of the key hurdles people cite in not working out is a lack of motivation," Feltz said. "Research has shown working out with a partner increases motivation, and with a virtual partner, you are removing the social anxiety that some people feel working out in public."

As part of the study, Feltz and her research team used the Eye Toy camera and PlayStation 2 to measure if a virtual partner motivated people to exercise harder, longer or more frequently. A plank exercise (which strengthens a person's core abdominal muscles) was used for nearly all 200 participants.

Participants performed the first series of five exercises alone holding each position for as long as they could. After a rest period, they were told they would do the remaining trials with a same-sex virtual partner whom they could observe during their performance. The partner's performance was manipulated to be always superior to the participant's.

Results showed that task persistence was significantly greater in all experimental conditions; those who exercised with a more-capable virtual partner performed the exercise 24 percent longer than those without.

"The fact that this effect was found with a virtual partner overcomes some of the practical obstacles of finding an optimally-matched partner to exercise with at a particular location," Feltz said.

Also, researchers have found live exercise partners are not always the most helpful.

"Individuals can become discouraged if they believe they can never keep up with their partner, or on the other hand, become bored if their partner is always slower," Feltz said. "With a virtual partner, this can be addressed."

As part of its Health Games Research, Robert Wood Johnson Foundation shares and supports quality, evidence-based research that explores and documents how digitally-delivered games are improving health and heath care. More than $10 million has been awarded.

Founded in 2007, Health Games Research currently funds 21 research studies on entertaining, effective health games and technologies that improve health behaviors and outcomes. For more information, visit www.healthgamesresearch.org.

Michigan State University has been working to advance the common good in uncommon ways for more than 150 years. One of the top research universities in the world, MSU focuses its vast resources on creating solutions to some of the world's most pressing challenges, while providing life-changing opportunities to a diverse and inclusive academic community through more than 200 programs of study in 17 degree-granting colleges.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
