Treadmill Shows Medieval Armour Influenced Battles

July 21, 2011 by ·

With the help of a treadmill, the team was able to assess how much energy someone wearing armour would have used (Footage: University of Leeds)

Medieval suits of armour were so exhausting to wear that they could have affected the outcomes of famous battles, a study suggests.

Scientists monitored volunteers fitted with 15th Century replica armour as they walked and ran on treadmills.

They found that the subjects used high levels of energy, bore immense weight on their legs and suffered from restricted breathing.

The research is published in the Proceedings of the Royal Society B. [Read more...]

KNOW ABOUT WALKING

Walking stretches your mind and your soul. It is dynamic mind & body process which creates a sense of rhythm. As you listen to your own silent rhythm, the pulse of life, your own heartbeat – you become whole, a complete man – fit in Mind, Body and Soul.

Walking energizes you, awakens you and stills your mind to fully relax. With the change of mind your moods change and you experience a physical and a spiritual upliftment. As you relax, your perception change and you reach from the everyday conscious mind to your highest level of mind – the intuitive mind. Your subconscious cuts through the mental clutter, releasing latent vitality and creativity, transcending traditional linear thinking and helping you find a creative solution. [Read more...]

Why Does It Seem Easier For Men To Lose Weight Than For Women?

January 17, 2011 by ·

Many women have watched in frustration as men they know trim beer bellies seemingly overnight, while they struggle to lose pounds. There’s truth to this observation, says George Blackburn, chief of the Nutrition/Metabolism Laboratory at Beth Israel Deaconess Medical Center. In weight loss trials that involve both sexes, he says, “the men are going to lose more weight than the women.’’ Part of this difference is that men simply have more to lose: The average man is taller, bigger, and burns more calories than the average woman. “It’s the difference between a V-6 engine and a V-8,’’ he says.

Blackburn says there are also societal differences in the way most women and men are exposed to food, which makes dieting harder for women. Women still purchase most of the food in this country, and they also prepare most of the food at home. That means that a woman may be exposed to much more food throughout the day than a man, giving her more opportunities for temptation. These differences in daily habits, combined with differences in metabolism and body type, Blackburn says, means that “the successful woman dieter has to be more together, more balanced, more structured, and more informed than the man.’’ [Read more...]

Consistent Exercise Linked To Lower Risk Of Colon Cancer Death

January 2, 2011 by ·

Consistent exercise is associated with a lower risk of dying from colon cancer, according to a new study led by researchers at the Siteman Cancer Center at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis. The study is among the first to show that physical activity can make the disease less deadly.

The Washington University researchers worked with colleagues from the American Cancer Society and examined data from the American Cancer Society Prevention Study II (CPS II) to look at whether changes in physical activity influenced either the incidence of colon cancer diagnosis or the risk of death from the disease.

The CPS II study included more than 150,000 men and women. To determine how exercise affected colon cancer, the researchers compared their levels of physical activity between 1982 and 1997, and linked those activity levels both to the number of colon cancer diagnoses between 1998 and 2005, and to the number of colon cancer deaths that occurred between 1998 and 2006. It turned out that those who exercised consistently for at least 10 years had the lowest risk of colon cancer death. [Read more...]

Fit For Life

November 13, 2010 by ·

Every profession has different nutritional requirements. Here’s taking a look into the diet charts of different professionals and the dos and donts that keep them fighting fit

His is an interesting ‘change in profession’ story. Manish Pole, director of Total Yoga, was first an advertising copy writer before he turned into a full-time yoga practitioner and teacher. “My earlier job, being extremely stressful, slowly started taking a toll on my health. To extirpate excess stress, I started practising yoga. Gradually, yoga became an intrinsic part of my life. It is then that I started teaching yoga on a full-time basis,” shares Pole. [Read more...]

The Cost Of Walking

November 12, 2010 by ·

Any parent that takes their kid out for a walk knows that children tire more quickly than adults, but why is that? Do kids and small adults walk differently from taller people or do they tire faster for some other reason? Peter Weyand from Southern Methodist University, USA, is fascinated by the effect that body size has on physiological function. ‘This goes back to Max Kleiber’s work on resting metabolic rates for different sized animals. He found that the bigger you are the slower each gram of tissue uses energy,’ explains Weyand, who adds, ‘It’s interesting to know how and why metabolism is regulated that way.’ Intrigued by the question of why smaller people use more energy per kilogram body mass than larger individuals when walking, Weyand teamed up with Maurice Puyau and Nancy Butte, from the USDA/ARS Children’s Nutrition Research Center at Baylor College of Medicine, and undergraduate Bethany Smith. Together they decided to measure the metabolic rates of children and adults, ranging from 5 to 32 years old, weighing between 15.9kg and 88.7kg and ranging in height from 1.07m to 1.83m, to try to find out why larger people are more economical walkers than smaller people. Weyand and his colleagues publish their discovery that walkers of all heights use the same amount of energy per stride, making short people less economical because they take more steps. They also derive a fundamental equation to calculate exactly how much energy walkers use with direct applications in all walks of life. The team publishes its discovery on 12 November 2010 in The Journal of Experimental Biology at http://jeb.biologists.org/cgi/content/abstract/213/23/3972. [Read more...]

Vigorous Exercise Reduces Breast Cancer Risk In African-American Women

October 3, 2010 by ·

Vigorous exercise of more than two hours per week reduces the risk of developing breast cancer in postmenopausal African-American women by 64 percent, compared to women of the same race who do not exercise, according to researchers at Georgetown Lombardi Comprehensive Cancer Center.

Results were presented at the Third AACR Conference on The Science of Cancer Health Disparities, held Sept. 30 to Oct. 3, 2010.

“People often want to know what they can do to reduce their risk of disease, and we have found that just two or more hours of vigorous activity per week can made a difference in one’s risk of developing breast cancer,” said the lead researcher Vanessa Sheppard, Ph.D., a cancer control scientist and assistant professor in the department of oncology at the Lombardi Comprehensive Cancer Center.
