Rhabdomyolysis at a Glance
Definition. Muscle breakdown that leaks harmful proteins into the bloodstream. Causes. Crushing injuries; repetitive bouts of eccentric exercise, intense exercise or high-repetition exercise; blood restriction to tissues; some drugs. Threats. Renal failure, blood clotting, irregular heart rate.
With health threats from overweight and obesity still looming, physical activity in schools continues to be a hot button. How do U.S. children rank when it comes to physical education and exercise? Here are some highlights from the 2012 Shape of the Nation Report: Status of Physical Education in the USA:
14% of students did not participate in at least 60minutes of physical activity on any day during the 7 days before the survey.
71% of students were physically active at least 60 minutes per day on fewer than 7 days during the 7 days before the survey.
Some people think they should skip bread because of its carbs, but new research shows that daily consumption of bread, especially whole-grain bread, can help prevent cardiovascular disease.
The study, which was part of the Functional Foods Consolider-Ingenio Project, used metabolomics techniques to analyze the impact of bread consumption (white and whole-grain). Led by professor Rafael Llorach from the University of Barcelona, the research focused on a group of 275 older volunteers who were at high risk of developing cardiovascular disease.newsletter_teaser: Some people think they should skip bread because of its carbs, but new research shows that daily consumption of bread, especially whole-grain bread, can help prevent cardiovascular disease.
There is a growing and compelling body of evidence that Alzheimer’s and Type 2 diabetes are linked by a common factor: insulin resistance. Earlier this year, researchers at the University of Pittsburgh proved it for the first time.
Inflammation, a protective mechanism designed to heal the body, has also been associated with disease development. Recently, a study discovered an inverse association between inflammation and long-term physical activity.
Published in Circulation (doi: 10.1161/circulationaha.112.103879), the 10-year study followed 4,289 men and women who were approximately 49 years old at the outset. “Self-reported physical activity and inflammatory markers (serum high-sensitivity C-reactive protein [CRP] and interleukin-6 [IL-6]) were measured at baseline and follow-up,” the authors explained.
Here’s another great benefit to including strength training in your clients’ fitness programs. A study in the Archives of Internal Medicine (doi: 10.1001/archinternmed.2012.3138) has reported that men who regularly lift weights may reduce their risk of developing type 2 diabetes.
Pilates-based mat exercises show promise as a way of helping people with multiple sclerosis (MS) improve both balance and stability. Impaired balance and loss of confidence with walking are common consequences of MS. Core stability training would seem a good candidate for complementary therapy, but till now, little scientific evidence has supported its effectiveness.
Researchers from several hospitals in England, Scotland and Wales conducted a multicenter series of case studies to evaluate the influence of Pilates-based mat exercises on balance and gait in ambulant people with MS.
For heart disease patients who also struggle with depression, exercise may offer as much relief from depressive symptoms as do prescription drugs, say researchers from Duke University Medical Center in Durham, North Carolina.
Having a sense of purpose in life—a tendency to derive meaning from life’s experiences and have a sense of direction or intention—may not only help you achieve goals but also contribute to keeping your brain healthy.
Researchers from Rush University Medical Center in Chicago studied data from 246 participants in the Rush Memory and Aging Project and found that higher levels of purpose in life reduced the effect of Alzheimer’s disease on cognitive decline.
Two human behaviors explain why we’re still here: engaging in sex and consuming food. Both are inextricably linked by dopamine, the neurotransmitter associated with reward and pleasure. It’s what motivates us to read all three volumes of Fifty Shades of Grey or to inhale a plate of mom’s homemade oatmeal raisin cookies. To date, procreative activities have maintained their primal prerogative without too much deviation from nature’s blueprint.
