Now that you are exercising, you will need a good pair of sneakers. What's the best?
Bargain Sneakers Better Than Pricey Models
That's the verdict from scientists at the Institute of Motion Analysis & Research at the University of Dundee in Scotland. They tested athletic shoes priced between $81 and $152 and found that the more affordable footwear provided the same level of durability and overall comfort as the higher-priced counterparts.
Even better: The less expensive sneakers actually provided more cushioning and support. --British Journal of Sports Medicine.

Fight 'Fatso' Gene with Exercise
One hour of moderate to vigorous exercise a day can help teens beat the effects of a common obesity-related gene with the nickname "fatso," according to a new European study. The message for adolescents is to get moving, said lead author Jonathan Ruiz of the Karolinska Institute in Sweden.
--Los Angeles Times, April 6, 2010.
Comment: Indeed, ALL are advised to be active in their own way: brisk walking, bicycling, jogging, the gym, or whatever... you've got to do something!

Exercise is an Anti-aging Miracle
New research actually proves that working out not only makes you look and feel younger but also makes you younger--right down to your DNA. Scientists found that regular exercisers have significantly longer telomeres (a region of DNA that acts as a biological marker for aging) than their sedentary peers. --Prevention July 2010.

Exercise Eases Depression
Trade in your Prozac or Zoloft for a good pair of walking shoes. That's right, researchers are finding that regular exercise can do wonders for your head. Many psychologists who have done research in this area are using "walking therapy" as part of their practice. They are finding that exercise:
* Helps lift depression
* Lessens tension
* Lessens confusion
* Increases optimism and hope
* Boosts self-esteem
* Increases energy
Case history: Carla, a woman in her 30s was very depressed, very overweight and suicidal. Her regular psychiatric sessions were not going well until a therapist induces her to begin exercising--in her case, pool walking and a bit of strength training (weight lifting). Gradually, it all changed for her. "She lost over 100 pounds, reduced her depression and got back on tract with her life," notes James Spira, Ph.D., M.P.H., at Duke University.
This, he points out is a typical case. Indeed, researchers are finding that in many cases exercise produces about the same level of response as medication--without the expense and side effects.
What is it about a good walk, run or swim that has the power to do a repair job when your head has a flat tire? "Walking, or other moderate exercise," explains Robert Thayer, Ph.D., "produces a holistic pattern of change--what I call general body arousal. Metabolism increases. Heart rate increases. Breathing increases. Tension in muscles goes down. There are changes in hormones and in brain neurotransmitters, which have a great influence on thinking and mood."
Dr. Thayer, a professor of psychology at Calif. State Univ. at Long Beach, recommends that "one of the first things a clinician should do in seeing depressed patients is to try to get them on an exercise program." He has found that the very best way to lift your mood is with regular exercise . --adapted from Prevention, May 1996.
Exercise, then as we have seen in other postings in this thread not only helps the body, but does much to get your head together, too.

Tater Tots
Children as young as 3 years of age are turning into couch potatoes, spending as little as 25 minutes per day--less than half the recommended time--in exercise and physical activity. This according to researchers at the University of Glasgow who found that many preschoolers "are as inactive as many office workers," increasing their risk of obesity. This research was published in the January 17, 2004 issue of The Lancet.

Move Your Body, Sharpen Your Mind
"Physical activity can make people more mentally alert," according to brain researchers Judy Cameron, PhD, of Oregon Health & Science University. "Now we're starting to understand why."
That's right, Dr. Cameron's research showed that monkeys who ran on treadmills grew more of the blood vessels that supply brain cells with oxygen- and sugar-rich blood. Active monkeys navigated a complex maze 2 times as fast.
Other researchers at the University of Wisconsin-Madison found that exercise stimulates production of a substance that prompts brain neurons to grow and link up. --adapted from Prevention, July 2004.

The Speedy Live Longer
Walking is a great way to invigorate mind and body, and all that healthiness may be associated with a longer life as well. In a study of adults over 65, those who walked faster were 90% likelier to live at least 10 more years than those who walked at a slower pace. Walking speed may be an indicator for how well the heart, luhngs, joints and muscles are functioning. --Time, Jan. 17, 2011.

Walking shortens Hospital Stay
An Israeli study of almost 500 patients over the age of 70 who spent at least 2 days in the hospital found that those who walked around their rooms or roamed the halls reduced their stay compared to those who remained in bed.
Results of the study showed that those who walked were discharged an average of a day and a half earlier.

Just a few minutes of daily exercise alters DNA to help prevent chronic disease
by John Phillip
(NaturalNews) Many people think the genes they inherited at birth are static and predetermine their fate for the remainder of their life. Extensive research into the science of epigenetics is providing startling evidence that this thought process is grossly outdated, and our individual DNA is dynamic and continually influenced by multiple lifestyle factors including diet, environment, stress and physical activity.
Researchers publishing the result of a study in the journal Cell Metabolism provide evidence that that when healthy but inactive men and women exercise for a matter of minutes, it produces a rather immediate change to their DNA. While we cannot change our core DNA code, exercise does influence the DNA molecules within our muscles. Scientists have found that DNA is chemically and structurally altered or expressed in very important ways that affect a myriad of metabolic processes that protect us from chronic disease.
The scientists found that DNA modifications signal precise genetic reprogramming in muscles that determine overall muscle strength as well as structural and metabolic benefits derived from physical activity. Study leader, Dr. Juleen Zierath noted "Our muscles are really plastic ... muscle adapts to what you do. If you don't use it, you lose it, and this is one of the mechanisms that allows that to happen."
Short bursts of moderate intensity exercise positively influences DNA expression
Epigenetic modifications involve the addition or deletion of chemical markers on the DNA strand that change rapidly based on environmental influences such as the nutritional composition of your last meal, pollutants in the environment or the intensity of an exercise workout. Researchers found that DNA within skeletal muscle examined after a short burst of exercise bore fewer chemical markers (specifically methyl groups) than it did before exercise.
The study team specifically determined that the DNA modifications occurred in stretches of DNA that are involved in expressing genes known to be important for muscular adaptation to exercise. This research clearly provides more evidence that our genetic constitution is continually evolving in an effort to protect us, and is positively influenced by short, moderately intense bursts of physical activity. These alterations allow us to adapt quickly to the changing environment that surrounds us.
Dr. Zierath concluded "Exercise is medicine ... and it seems the means to alter our genome for better health may be only a jog away." The finding of this study may explain recent research showing that the best form of exercise works our musculature in short bursts of moderate to full intensity (as measured by attaining maximum heart rate for your age range) for several minutes in duration, followed by a rest period and then another energy burst. Combining this evidence with an organic whole food diet will positively influence your genes toward optimal health.

Exercise boosts healthy DNA expression within just a few minutes
by Jonathan Benson, staff writer
(NaturalNews) Exercise truly is a vital component of good health, as was once again illustrated in a recent study published in the peer-reviewed journal Cell Metabolism. Researchers from the Karolinska Institute in Stockholm, Sweden, the University of Copenhagen in Denmark, and Dublin City University in Ireland found that just a few minutes of rigorous exercise is enough to spur almost immediate changes in DNA that improve the ways health-regulating genes express themselves.
For their study, the research team asked a group of young people to undergo an intense, 20-minute workout session on stationary exercise bikes that was designed to get their hearts pumping and their bodies sweating. Upon completion, samples of muscle tissue were examined and compared to samples from those that had not participated in the exercise.
It turns out that, while one's actual genetic code is not changed by exercise, DNA methylation, or the process by which genes are told whether or not to remain "on" or "off," is altered in such a way as to improve normal bodily function. Based on a comparison of skeletal muscle both before and three hours after exercise, Professor Juleen Zierath and her colleagues observed that exercise demonstrably spurs DNA to better transport fats, sugars, and other nutrients throughout the body, as well as protect cells from oxidative damage.
"The changes in methylation and expression for the genes studied are important for mitochondrial function, glucose transport as well as fat transport and oxidation," said Dr. Donal O'Gorman, director of the Centre for Preventive Medicine at Dublin City University, one of the researchers involved in the study. "The findings support the view that regular activity is necessary for metabolic health and the prevention of chronic diseases such as type 2 diabetes."
Though the DNA changes were only temporary, they do help illustrate how the body reacts to exercise, and how the muscles being worked by exercise respond in terms of growth and nutrient transport. By getting just a few minutes of rigorous exercise every day, you are essentially teaching your DNA how to distribute nutrients, build muscle, and ultimately improve health.
"Our muscles are really plastic," said Prof. Zierath in reference to the findings. "We often say, 'You are what you eat,' well, muscle adapts to what you do. If you don't use it, you lose it, and this is one of the mechanisms that allows that to happen."
