It's one of the hardest jobs in sport that every armchair fan thinks they can do better. But QUT research has revealed the reasons how and why referees make decisions that can regularly enrage and frequently frustrate supporters. Football referee and QUT researcher Scotty Russell has investigated why referees make the calls they do and what they want to achieve from the matches they officiate.
Researchers at UNIGE have studied the neuronal activity of people faced with making the choice between physical activity and doing nothing. They noted that the brain requires far greater resources to escape a general attraction to minimising effort. A struggle then breaks out between the desire to do nothing and the physical activity. The results are consistent with the idea that our ancestors had to avoid unnecessary physical effort to increase their chances of survival.
Society has encouraged people to be more physically active, yet we are actually becoming less active. This new study offers a possible explanation: Our brains may be innately attracted to sedentary behavior. Electroencephalograms showed that test subjects had to summon extra brain resources when trying to avoid physical inactivity.
The sport of rock climbing is gaining international attention, having been approved for inclusion in the 2020 Olympic Games. But news headlines about the sport are still dominated by reports of gruesome injuries and near-death falls. Are rock climbers going out of their way to seek these risks? A new study published in Risk Analysis: An International Journal reveals that decreasing the level of injury risk at a climbing site generates substantial welfare gains for climbers.
Pectus excavatum, pectus carinatum, Poland syndrome, sunken chest deformity, barrel chest deformity, body builder deformity, and long upper chest wall are chest wall deformities that are documented in the medical literature.
Requiring physical activity classes in college encourages sedentary students to become more active, while elective classes tend to draw those who are already motivated, new research from Oregon State University has found.
Learning to read the game is as important to young footballers as kicking a ball. A new study, which highlighted Frank Lampard and Steven Gerrard as stars who incorporated the technique into their gameplay, calls on coaches to spend more time training young players to scan the field and less on ball skills.
A recent Finnish study conducted at the University of Jyväskylä showed that adolescents with better aerobic fitness have more compliant arteries than their lower fit peers do. The study also suggests that a higher anaerobic threshold is linked to better arterial health. The results were published in the European Journal of Applied Physiology.
The amount of physical activity that women undertake is not linked to their risk of early menopause, according to the largest study ever to investigate this question. Until now, there have been conflicting findings about the relation between physical activity and menopause, with some studies suggesting that women who are very physically active may be at lower risk of a menopause before the age of 45, while others have found evidence of the opposite effect. The study is published in Human Reproduction.
Middle-aged adults are exercising more and living longer, but new research from the University of British Columbia suggests that even the fittest among them are not immune to cardiovascular disease -- and they often don't have any symptoms.
