Live longer and wear it well The hard fact of aging is the body’s decline of function: Muscles lose strength and mass, bones become fragile, the heart beats slower, and brain function becomes impaired before death. But new evidence shows that exercise is linked to mortality and aging. A recent 20 year follow-up study by Kokkinos and others showed that mortality risk in older men (age 65-92) is 38 percent lower for those who achieved exercise capacity of 5.1-6.0 metabolic equivalents (approximately an hour of brisk walking). More exciting news is that a family of genes called sirtuins , identified as key longevity and quality of aging regulators, mediate the response to exercise and are involved in many processes that can alter the process of aging. In fact, if scientists experimentally add extra amounts of a specific sirtuin to male mice, it extends their life span by 15 percent. The products of the sirtuin genes work by regulating the expression of genes and modifying the activity of enzymes.

Exercise Trains Troops for Nuclear Disaster

Rex Curry/Special Contributor Kim Williams, a personal trainer with Baylor Health Care System, demonstrates an intense 10-minute workout. 1 3 In the futuristic world of winsome dreams, cheeseburgers have single-digit calories; workouts, single-digit minutes. Well, hold tight to your jet pack. The magic wand has been waved not for cheeseburgers, but it seems so for workouts.

Exercise may cut endometrial cancer risk for heavy women

He serves with the 51st Civil Support Team, or CST, Michigan National Guard, Joint Force Headquarters, out of Battle Creek, Mich. “This is a unique, realistic training environment.” Taking advantage of the unique training environment are the CST units, which have specific missions they train for in order to prepare them for a real-world, American catastrophe. “The mission for our unit, during the training, is to assist the first responders by providing route reconnaissance as well as setting up decontamination sites; we would handle the CBRN incidents,” explained Erridge. The CST’s primary mission is to support the incident commander as well as those first responders (local, state and federal) by establishing safe areas through route reconnaissance and determining where there are potential radiological and chemical hazards, explained Maj. Ronald Crane, commander of the 53rd Civil Support Team, Indiana National Guard, Joint Force Headquarters Indiana, from Indianapolis.

How few minutes of exercise can you get away with?

Strenuous and moderate physical activity were linked to lowered risk for heavy women, but there was no association between activity level and endometrial cancer risk for thinner women, Christina M. Dieli-Conwright of the Beckman Research Institute of City of Hope in Duarte, California, and her colleagues found. “Physical activity is a good thing, however its involvement in reducing the risk specifically with endometrial cancer does need to be further investigated,” Dieli-Conwright told Reuters Health. While the evidence is strong that both vigorous and moderate physical activity can reduce breast cancer risk, she added, “with endometrial cancer it’s not so straightforward.” Some past studies have already linked increased physical activity to reduced endometrial cancer risk, she and her colleagues note in their report, published in the British Journal of Cancer. To investigate whether a woman’s body size might influence that relationship, the researchers looked at 93,888 participants in the California Teachers Study, 976 of whom were diagnosed with endometrial cancer between study enrollment in 1995-1996 and the end of 2007. Heavier women who reported at least three hours a week of strenuous recreational physical activity at the beginning of the study had a 24 percent lower risk of developing endometrial cancer over the next dozen years compared to women who got less than half an hour of vigorous exercise each week, the researchers found.
