Dustin’s Health & Fitness Articles of the Week – 4/6/14

Top 5 Reasons Your Diet Isn’t Working – A study in 2010 “compared two groups of overweight non-smokers on calorie restricted diets for 14 days. One group clocked 8.5 hours of sleep per night, and the other logged 5.5 hours of sleep per night (which the authors point out is a “norm” for people in this day and age.) Both groups ate roughly 1,450 calories a day. After two weeks, the people who slept more lost more fat than the group who slept less. More than half of the weight loss during the 8.5 hours of sleep was fat versus only one quarter of the weight loss during the 5.5 hours of sleep. People literally burned fat while they slept. The folks who slept less lost more muscle (60% more muscle was lost by the sleep-deprived group.) Those three hours of lost sleep caused a shift in metabolism that made the body want to preserve fat at the expense of muscle. When the researchers compared circulating blood levels of appetite-regulating hormones in the two groups they found those who slept for three fewer hours had produced more of the appetite stimulating hormone ghrelin. They woke up hungrier!” -Woodson Merrell

Fitness Reborn: The Real Truth About Carbs – The Top-10 countries in the world with the lowest obesity rates all consume a carb-dominant diet. Of the 10 countries with the lowest obesity rates, 8 are in Asia, and the remaining 2 are in Africa.

Shivering ‘as good as exercise’ for producing brown fat – New research shows that adults are capable of transforming energy-storing white fat into energy-burning brown fat by two similar muscle contracting mechanisms: exercise and shivering.

Drug Use in Sports: Can We Ignore It Any Longer? – The sports adage “if you ain’t cheatin’, you ain’t trying” seems to be the line of thinking taken too seriously among athletes these days. In cycling, more than a third of the top finishers of the Tour de France have admitted to using performance-enhancing drugs in their careers or have been officially linked to doping.

Training to Bobsled – This is a short video about U.S. Olympic Team bobsled training and a few exercises in their workout. Chris Fogt, the American bobsledder in the video is also a Captain in the U.S. Army and participant in the U.S. Army World Class Athlete Program (located in Fort Carson for you Coloradans) which allows soldiers the opportunity to train and compete at national and international sports competitions.
