pregnantBaylor College of Medicine researchers have discovered that female mice that voluntarily exercise during pregnancy have offspring that are more physically active as adults. The research appears in The FASEB Journal.

Dr. Robert A. Waterland, associate professor of pediatrics – nutrition and of molecular and human genetics at the USDA/ARS Children’s Nutrition Research Center at Baylor and Texas Children’s Hospital and senior author of this work, noted that although their research studied mice, “several human studies have reported results consistent with ours.”

For example, observational studies have found that women who are physically active when they are pregnant have children who tend to be more physically active. But these results could be attributed to the mothers’ influence on the children after they were born. Or, mothers could pass to their offspring a genetic predisposition to be physically active.

“Our study in a mouse model is important because we can take all those effects out of the equation. We studied genetically identical mice and carefully controlled the amount of physical activity of the mothers before pregnancy,” said Waterland.

The Baylor team selected female mice that all enjoyed running. Then they divided them into two groups. One was allowed access to running wheels before and during pregnancy, and the other was not.

During early pregnancy, the females with running wheels ran an average of 10 kilometers a night. They ran less as pregnancy progressed, but even by the beginning of the third trimester they ran (or walked) about 3 kilometers each night.

The researchers found that the mice born to mothers that exercised during pregnancy were about 50 percent more physically active than those born to mothers who did not exercise. Importantly, their increased activity persisted into later adulthood, and even improved their ability to lose fat during a three-week voluntary exercise program.

This study supports the idea that movement during pregnancy influences fetal brain development, making the offspring tend to be more physically active throughout life. “Although most people assume that an individual’s tendency to be physical active is determined by genetics, our results clearly show that the environment can play an important role during fetal development,” Waterland said.

If a similar effect can be confirmed in people, it could represent an effective strategy to counteract the current worldwide epidemic of physical inactivity and obesity.

Increasing physical activity has major health implications. According to the World Health Organization, insufficient physical activity is one of the 10 leading risk factors for death worldwide.

Several expert groups including the American College of Obstetricians and Gynecologists already recommend that, in the absence of complications, pregnant women get 30 minutes or more of moderate exercise a day. “I think our results offer a very positive message,” said Waterland. “If expectant mothers know that exercise is not only good for them but also may offer lifelong benefits for their babies, I think they will be more motivated to get moving.”

Gravity And Running

By Jack Nirenstein

girljogThe single force that makes all of us walk run and sprint is being taught incorrectly by all the gurus in the world. The force is gravity. Most gurus believe that you push yourself forward to run. The pushing method will make your leg collapse. It would require you to release the muscles that cross the front of the knee that straightens the leg to support your body and toss you in the air.

Lately a gravity method has been made popular. The gurus that teach it have the gravity method wrong. Their way would also make you fall to the ground. They want their students to stay straight as a pole and hold that pose at a forward slant without bringing the foot forward. When they demonstrate how it looks they bring their feet forward and hope nobody notices them doing it.

I first discovered my true gravity technique by seeing how I run and saw that it is the only way anybody can run. So you all run somewhat correctly.

You cannot stand in place without the force of gravity holding you there. You cannot run without your strides being off balance. I observed that at a steady pace the feet always land slightly ahead of the waist for everyone. The area around the waist is where the full weight of the body is. The forward slant of the body will not make you move forward if the waist is vertical over the feet. It is bad posture to slant the upper body forward to run. It hurts your back muscles and rounds your shoulders to crunch your body.

joggersThe lesson to run is to take notice of how you run so you can run relaxed, perform better and avoid injuries. To pick up speed everyone lands behind their waist for as many strides as it takes to get to their pace. To stop picking up speed everyone lands slightly ahead of their waist and you can only stay at a steady pace that way. To pick up speed again you must land behind your waist again. To slow down you land far ahead of your waist to reverse the pull of gravity.

As an example when you land slightly ahead of your waist on your first stride you go into a walk. When you land behind your waist for three strides you go into a run. When you land behind your waist for ten strides you go into a sprint.

The faster your run the feet spread farther apart. The foot gets flipped back and high. To keep speeding up you must know how to return the feet forward fast to keep you in balance for the speed.

The new barefoot running trend claims to be more efficient than running with shoes is also insane. The gurus claim that running with running shoes forces you to land on your heels and land far ahead of your waist with a straight leg to destroy your joints. You can only run backward landing far ahead of your waist. And when you land far out front running backward, it can be done with a bent knee to protect your joints. You can also land on any part of the foot with running shoes. I have a method to land softly and build your joints stronger.

I am the author of a book called, Nirenstein’s First Law of Running. I applied Newton’s Law of Gravity to running correctly for the first time. Gravity is a vertical force but it cannot push the grounded foot down when the body’s center is at an angle. It rotates the leg around the grounded foot. When the body is tossed up at an angle it comes down a stride length ahead.

Food Marketers To Kids: You Can Run, But You Can’t Hide

From Your Health Journal…..”Most of my regular visitors know one of my favorite sites to plug is called Take Part. I love their site, and always telling people to go there for quality, informative articles. Today’s review comes from this site called, Food Marketers To Kids: You Can Run, But You Can’t Hide by By Steve Holt – who did an excellent job. I encourage all of you to visit the Take Part site (link provided below) to read the complete article. Parents not only have to worry about ads on TV that promote unhealthy eating, now they have to worry about marketing to children on the internet. In a recent report, the FTC found that while overall spending on food marketed to children fell nearly 20 percent between 2006 and 2009, online marketing increased by 50 percent in that same time period. This may be a larger problem, as many children spend more time on their computers than the TV. Why has nothing happened? One of the biggest reasons change has been so minimal in coming to the marketing and nutrition of kids’ foods is that few meaningful standards exist, leaving companies to regulate themselves on a voluntary basis. Please, visit the Take Part web site to read the complete article. It is an important one to read!”

Short snip from the article…..

Television isn’t the only place for companies to pedal their unhealthy wares anymore—online sites and games are the new frontier.

It’s not enough anymore for parents to worry about the food advertising their children see on television. No, food companies have laid claim to new hunting grounds for the hearts, minds and bellies of America’s youth, 32 percent of whom are overweight or obese: the Internet.

In a report published in late December, the FTC found that while overall spending on food marketed to children fell nearly 20 percent between 2006 and 2009, online marketing increased by 50 percent in that same time period.

Food companies spent $1.8 billion to market food to children ages 2-17 in 2009, but the data clearly shows that companies only shifted their marketing bucks away from expensive television ads to media where children are spending more of their time—the Internet and mobile devices.

The sneaky tactics food companies now use online—like embedding junk food advertising in interactive games on popular websites like Nick.com—reach children who are completely unaware they are being targeted, says Jennifer Harris, director of marketing initiatives at Yale University’s Rudd Center for Food Policy and Obesity.

“There are no controls over online advertising to kids like there are for children’s television,” she says. “Companies can basically advertise any way they want on the Internet. They’re taking advantage of children’s inability to critically review advertising.”

The ubiquitous nature of Internet food ads and their success attracting kids may be startling, but it should come as no surprise. Older youth aged eight to 18 spend as much as seven hours a day online and kids under five use the Internet weekly.

Harris says research has shown that children don’t recognize advertising as well online as when they see it on television, especially when they’re cleverly disguised as games. When food ads are embedded in online games, children may even eat more food—and more junk food in particular. In a study published in late December, Dutch researchers had eight- to 10-year-olds play food- and non-food-related memory games on the Internet and then offered them bowls of jelly candy, chocolate, sliced bananas, and apples. The kids who played the food games ate more of the unhealthy food—and twice as much food overall—than the kids who played non-food games or no game at all.
