(Press-News.org) Toronto, ON – November 24 – It's never fun riding the bench – but could it also make you less likely to be physically active in the future?
That's one of the questions being explored by Mark Eys, an associate professor of kinesiology and physical education at Wilfrid Laurier University and the Canada Research Chair in Group Dynamics and Physical Activity. Eys is presenting his work as part of this week's Canada Research Chairs conference in Toronto.
Eys, who also teaches out of the university's psychology department, is studying group cohesion – which, in sporting terms, is essentially that sense of camaraderie that often develops between teammates – and how it affects the willingness of teenagers to take part in physical activity long-term.
It's an important connection to study, he says, since it's much more common for people to work out in groups than on their own.
"People playing sports, for instance, are usually part of a group. If they're playing golf, they're in a group. They're often going for runs in a group," says Eys.
"If we understand how those groups work, and take advantage of those situations, we can facilitate physical activity."
For the past two years, Eys and his team of graduate students have been observing teens aged 13-17 in the Sudbury area, tracking them as they take part in high school sports, rec leagues, and non-structured group activities like running and jogging.
Once a year, says Eys, they fill out questionnaires that measure how they feel about the level of cohesion in their groups. The teens taking part in highly-structured sports, particularly at the high school level, are asked specifically about their teams' focus – how it strikes a balance between self-improvement and winning.
While they're still analyzing the first two years of data, Eys points out that, so far, they've found "a really strong relationship between that motivational climate and perceptions of cohesion."
That relationship seems to echo the findings of researchers who've posed the same questions to adults, says Eys.
"If you look at the research on adults, the link between group perceptions and cohesion is pretty clear," he says. "If people are in groups that they enjoy, they're more likely to stick to their exercise regimens."
For Eys, his research isn't purely academic – it's also personal. A decade ago, Eys played basketball at the University of Waterloo, and in his fourth year made it to nationals. While the team didn't win, they managed to strike a near-perfect balance, he says, between competitiveness and camaraderie.
"We still, to this day – and this is ten years after the fact – get together as a group. It was obviously a very cohesive bunch. I don't think we were necessarily the most talented group in the league, but some of these group processes can overcome that."
Eys also has two daughters, aged six and four, who are "taking their first steps into organized activities." Researching what it is that makes a good group activity, he says, will translate into an increased likelihood that physically active kids become physically active adults.
The goal of his research is to "have something to be able to take to coaches, to be able to take to organizations" that would outline all those factors that go into a cohesive group environment. Making kids play better, may help them play longer.
The study will continue for at least one more year and is expected to expand to include kids in the Kitchener-Waterloo area, says Eys.

Bonn, 24th November 2010. Metformin, a drug used in type 2-diabetes might have the potential to also act against Alzheimer's disease. This has been shown in a study from scientists of the German Center for Neurodegenerative Diseases (DZNE), the University of Dundee and the Max-Planck-Institute for Molecular Genetics. The researchers have found out that the diabetes drug metformin counteracts alterations of the cell structure protein Tau in mice nerve cells. These alterations are a main cause of the Alzheimer's disease. Moreover, they uncovered the molecular mechanism of ...
You may think of your love for your mate as the noble emotion of a pure heart, but some primitive parts of your brain are taking a decidedly more pragmatic approach to the subject, according to Stanford biologists.
In experiments with African cichlid fish, the scientists discovered that when a female shows a preference for a particular male, but then witnesses him losing a fight with another male, her feelings toward him change.
Areas of the female's brain associated with anxiety showed increased activity after witnessing an altercation.

An international team of immunologists studying the effects of cannabis have discovered how smoking marijuana can trigger a suppression of the body's immune functions. The research, published in the European Journal of Immunology, reveals why cannabis users are more susceptible to certain types of cancers and infections.
The team, led by Dr Prakash Nagarkatti from the University of South Carolina, focused their research on cannabinoids, a group of compounds found inside the cannabis plant, including THC (delta-9 tetahydrocannabinol) which is already used for medical ...
As the eurozone continues to wobble, new analysis of countries' economic interconnectedness finds that some of the countries with the greatest potential to cause a global crash have surprisingly small gross domestic production.
Using data from Bureau Van Dijk - the company information and business intelligence provider - to assess the reach and size of different countries' economies, and applying the Susceptible-Infected-Recovered (SIR) model, physicists from universities in Greece, Switzerland and Israel have identified the twelve countries with greatest power to spread ...
Fifty-seven laboratories from 29 countries volunteered to put their measuring competence to the test. Each laboratory received a sample without knowing the levels of heavy metals present, and was asked to measure and report the values back to the JRC.
The good results should enhance consumers' confidence, as maximum levels of lead, cadmium and total mercury in seafood are regulated by EU law and it has been proven that most participants are able to correctly measure them. In addition, this comparison has highlighted other issues, such as the apparent dependency of the ...
About 30% of breast cancer patients have tumours that show rapid growth and invasion through the body. A common denominator in all of these cases is the presence of a large number of Her2 proteins in tumour cellular membranes. Consequently, these aggressive tumours are referred to as HER2+. Scientists working in the Metastasis Laboratory (MetLab) at IRB Barcelona headed by ICREA researcher Roger Gomis, have described the molecular mechanism that induces HER2+ tumours to ignore the signals that protect cells from excessive growth. The study is published this week in the ...
In the wake of devastating cholera outbreaks in refugee camps in earthquake-wracked Haiti, a group of leading experts from Harvard Medical School, George Washington University, and the International Vaccine Institute (IVI) have urged the United States to create an emergency stockpile of cholera vaccines for future humanitarian use.
"The costs to the U.S. of creating and maintaining a stockpile of several million doses of cholera vaccine would be low," said the experts in an article published online first on November 24 in The New England Journal of Medicine (NEJM). "But ...
A new process for creating a personalized vaccine may become a crucial tool in helping patients with colorectal cancer develop an immune response against their own tumors. This dendritic cell (DC) vaccine, developed at Dartmouth and described in a research paper published this week in the journal Clinical Cancer Research, was used after surgical resection of metastatic tumors to try to prevent the growth of additional metastases.
"The results of the study suggest a new way to approach cancer treatment," said Richard Barth Jr., MD, Chief of General Surgery at Dartmouth-Hitchcock ...
The search is on for insects, mites, microbes or nematodes that could be used in a biologically based approach to controlling silverleaf nightshade, an invasive weed from the Americas that has spread to southern Europe, Africa, India, Australia and elsewhere.
According to U.S. Department of Agriculture (USDA) entomologist Walker Jones, the perennial weed, Solanum elaeagnifolium, is being targeted for its ability to outcompete native plants, reduce crop yields and diminish pasture productivity. Its orange, toxin-producing berries can also poison livestock.
