Science Weekly
A weekly round up of scientific research for personal trainers. Join for free to get Science Weekly updates delivered straight to your inbox.
 Plenty of papers published in the last week and the topics are varied within the fields of fitness, nutrition and sports science. There's something for personal trainers with elderly clients, people with lifestyle conditions, kids or even for the geeks. Not to mention the one on how facemasks affect cognition in hot environments. This week's highlights:
Is sitting always bad for your mind? A new study suggests maybe not It's generally accepted health advice that adults of all ages should sit less, move more, and engage in regular exercise to feel better and reduce the risk of chronic diseases. However, when it comes to the brain and cognition, a new study of older adults suggests that some sedentariness isn't all bad, so long as basic physical activity benchmarks are being met.

New peer-review paper looks at evolution and current Western diet to help explain manic behaviors New research suggests that conditions such as attention deficit hyperactivity syndrome (ADHD), bipolar disorder, and even aggressive behaviors may be linked with sugar intake, and that it may have an evolutionary basis.

Poor people in developing countries are most affected, as their diets are typically dominated by starchy staple foods, which are inexpensive sources of calories but contain low amounts of micronutrients. Researchers now explain how plant genetic engineering can help to sustainably address micronutrient malnutrition.

Both groups improved in physical and cognitive function, with added gains among those who regularly consumed the nutritional beverage, the team reports.

Cognitive behavioral therapy (CBT) is one of the first-line treatments for insomnia, but it's never been tested on young adults who are actively drinking. Researchers evaluated CBT's effect on young adult binge drinkers with insomnia to determine if this treatment can improve their sleep and potentially affect alcohol use outcomes.

However, wearing a facemask does make it more difficult to breathe when performing moderate physical work in a hot environment. Source: Faculty of Science - University of Copenhagen Vitamin A boosts fat burning in cold conditions The conversion of white into brown adipose tissue is a promising target for obesity treatment A recent study shows that cold ambient temperatures increase vitamin A levels in humans and mice. This helps convert 'bad' white adipose tissue into 'good' brown adipose tissue which stimulates fat burning and heat generation.

The simplicity of their system could be conducive to a wide range of applications in the sports, medical and entertainment fields.
