Here’s today’s COMMENT FROM AN OLD BLACK FART: sitting on your fat butt can make you stupid. Science Daily reported in Types of athletic training affect how brain communicates with muscles:
Using endurance training or strength and resistance training not only prepares an athlete for different types of sports, they can also change the way the brain and muscles communicate with each other.
A University of Kansas study shows that the communication between the brain and quadriceps muscles of people who take part in endurance training, such as running long distances, is different than those who regularly took part in resistance training and those who were sedentary. The findings may offer clues to the type of physical activity humans are most naturally suited to.
Trent Herda, assistant professor of health, sport and exercise sciences, and Michael Trevino, a doctoral student, conducted studies in which they measured muscle responses of five people who regularly run long distances, five who regularly lift weights and five sedentary individuals who regularly do neither. The studies have been published in the Journal of Sports Sciences and Muscle and Nerve.
Among the findings, Herda and Trevino showed that the quadriceps muscle fibers of the endurance trainers were able to fire more rapidly.
“The communication between the brains and their muscles was slightly different than the resistance trainers and sedentary individuals,” Herda said of endurance trainers. “This information also suggested that resistance trainers and those who are sedentary were more likely to fatigue sooner, among other things.”
Survey participants were 15 healthy volunteers. The endurance trainers had consistently taken part in a structured running program for at least three years prior to the study and ran an average of 61 miles a week and did not take part in resistance training. The resistance trainers had consistently taken part in a weight-training program for at least four years prior to the study. They took part in resistance training four to eight hours per week and reported doing at least one repetition of a back squat of twice their body mass. One reported doing a squat of 1.5 times his or her body weight, but none engaged in aerobic activity such as swimming, jogging or cycling. The sedentary participants did not take part in any structured physical exercise for three years prior to the study…http://www.sciencedaily.com/releases/2015/09/150918132022.htm
Although, the University of Kansas study looked at how different types of exercise affect the communication of the brain with muscles, this is in accord with the Health and Fitness Association (Association) post, The Exercise–Brain Connection.
According to the Association:
Cognitive Function
A sedentary lifestyle affects the brain—and in turn lessens mental capacity. Sibley and Etnier (2003) found a clear connection between how much schoolchildren exercised and their cognitive performance: the more aerobic exercise the children engaged in, the better they performed on verbal, perceptual and mathematical tests. The same pattern of results was found in older adults: aerobic training improved cognitive performance (Colcombe & Kramer 2003), and active lifestyles decreased age-related risks for cognitive impairment and dementia (Yaffe et al. 2009). Not surprisingly, these cognitive effects were accompanied by clear changes in brain structure and function…. http://www.ideafit.com/fitness-library/the-exercisendashbrain-connection
Jennifer Larino of the Times-Picayune (NOLA) reported in Couch potato crisis? More Americans ‘totally sedentary,’ Wall Street Journal reports:
The number of Americans who say they have participated in no physical activity in the past year has hit its highest point since 2007, The Wall Street Journal reports.
The report cites figures from the annual Physical Activity Council, which reports about 28 percent of Americans age 6 and over were “totally sedentary” last year, meaning they did not participate at least once in any of the more than 100 physical activities the survey listed. That is about 83 million Americans total.
That is the highest level of inactivity since the survey fine-tuned its sports and fitness list, excluding activities such as billiards and darts, the report says….http://www.nola.com/news/index.ssf/2015/04/more_americans_totally_sedenta.html
This rise in the number of sedentary individuals affects both the national health, but the ability to participate in the democratic process. A stretch, the reader might opine. Consider this quote from Jon Gruber, the architect of Obamacare:
Lack of transparency is a huge political advantage. And basically, call it the stupidity of the American voter or whatever, but basically that was really really critical for the thing to pass

See, Obama promised Obamacare wouldn’t do exactly what Gruber says it will do http://www.cnn.com/2014/11/18/politics/gruber-obamacare-promises/index.html
Bottom line, pun intended is that sedentary folk harm their health, the wealth of the country paying increased health care costs and the political dynamic because they don’t have the mental or physical energy to participate giving the Jon Grubers of the world, free reign.
