Putting on the pounds after weight loss? Hit the gym to maintain health gains
Resistance training while regaining weight reduces disease risk factors, MU scientists find
2010-09-22
(Press-News.org) COLUMBIA, Mo. – Although obesity is a major risk factor for disease, much of the threat may be associated with the metabolic (or cardiometabolic) syndrome, a cluster of risk factors related to diabetes and heart disease. Losing weight can improve health and reduce many of these risk factors. However, many people struggle to keep the weight off long-term. Now, researchers at the University of Missouri have found that people who perform resistance training while regaining weight can help maintain strides in reducing their risks for chronic disease.
"Long-term weight loss maintenance is uncommon without regular exercise," said Shana Warner, a doctoral student in the MU Department of Nutrition and Exercise Physiology. "It is very important to address other things that can be done to maintain health as opposed to focusing solely on body weight. Our research indicates that following a consistent exercise program can help maintain certain aspects of metabolic health, even in those who experience weight regain."
The study consisted of two phases, meant to simulate real-life weight loss and regain. In the first phase, overweight and obese participants lost 4 to 6 percent of their initial body weight by following an eight to 12-week regimen of diet and aerobic exercise. In the second phase, participants regained 50 percent of the weight they had lost. During the regain phase, participants performed 45 minutes of supervised resistance training three times each week.
Researchers found that weight training during weight regain has a positive effect on health, which can reduce the risk of diabetes, heart disease and other diseases. Participants maintained improvements acquired through weight loss in cardiorespiratory fitness, body fat percentage, systolic blood pressure and other factors. In addition, participants significantly increased strength and lean body mass. However, they did not maintain reductions in visceral abdominal fat: the fat deposited around internal organs.
This study furthers research completed earlier this year, in which MU researchers found that participation in aerobic exercise while regaining weight counters many of the risk factors associated with chronic diseases. These studies are some of the first to consider the effects of exercise on people's health who regain weight they recently lost.

The study, "The Effects of Resistance Training on Metabolic Health with Weight Regain," was published this year in The Journal of Clinical Hypertension. Researchers from the Department of Nutrition and Exercise Physiology (part of the College of Human Environmental Sciences, the School of Medicine and the College of Agriculture, Food and Natural Resources) completed the study in conjunction with MU scientists in the Department of Internal Medicine, the Department of Medical Pharmacology and Physiology, and the Harry S. Truman VA Memorial Hospital.

Imagine devices that capture electricity from the air — much like solar cells capture sunlight — and using them to light a house or recharge an electric car. Imagine using similar panels on the rooftops of buildings to prevent lightning before it forms. Strange as it may sound, scientists already are in the early stages of developing such devices, according to a report at the 240th National Meeting of the American Chemical Society.
"Our research could pave the way for turning electricity from the atmosphere into an alternative energy source for the future," said study ...

Portable devices that use a laser beam to probe bones, teeth, and other parts of the body for early signs of diseases like osteoporosis and tooth decay may seem like something out of science fiction. But those devices are moving closer to reality, according to an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.
C&EN Senior Editor Celia Henry Arnaud notes that these new diagnostic tools will have the ability to see beneath the skin and detect disease, without exposing patients to X-rays. They embrace a technology that involves ...

Toronto, Canada – In an international study of patients with a devastating type of dementia that often strikes in middle age, researchers have found intriguing evidence that career choice may influence where the disease takes root in the brain.
The study was led by Baycrest's Rotman Research Institute in collaboration with the Memory and Aging Centre at the University of California, San Francisco and several U.S. and European clinical sites. It appears online today in the Article in Press section of the journal Neuropsychologia, ahead of publication.

A study led by St. Jude Children's Research Hospital investigators links the muscle weakness and other symptoms of a rare neurodegenerative disease to a misstep in functioning of a normal protein, rather than its build-up inside cells. The finding offers insight into the mechanism driving common nervous system disorders like Parkinson's and Alzheimer's diseases.
The work advances understanding of how the inherited mistake at the heart of spinobulbar muscular atrophy (SBMA) leads to the death of neurons in the brain and spinal cord. Investigators showed that the underlying ...

September 22, 2010 -- Most studies of the food choices available near public schools have focused on fast food outlets rather than the full range of options available to schoolchildren. A new study by researchers at Columbia University's Mailman School of Public Health examined the patterns of exposure to a broad range of food outlets for school children in New York City.
The study, "Disparities in the Food Environments of New York City Public Schools," is published in the American Journal of Preventive Medicine Volume 39, Issue 3, and cited as the "Editor's Choice" ...

Bethesda, Md. (September 22, 2010) – Taking chromium picolinate may help lessen inflammation associated with diabetic nephropathy (kidney disease), say researchers at the Medical College of Georgia in Augusta. In a study comparing diabetic mice treated with chromium picolinate with those that received placebo, the researchers found that mice who received the supplement had lower levels of albuminuria (protein in the urine), an indication of kidney disease.
The Study
To arrive at their conclusions, the researchers compared three groups of mice, one lean, healthy group ...

(Santa Barbara, Calif.) –– Sometimes, treasures can be found in your own backyard –– especially if you know what to look for. This is what happened to Jeff Goddard, project scientist with the Marine Science Institute at UC Santa Barbara.
Goddard was working in the tide pools at Carpinteria Reef, in Carpinteria State Park, Calif., when he found a new species of nudibranch –– a group of sea slugs noted for their bright colors and delicate forms. Recognizing it as new, Goddard carefully documented the living specimen before preserving it and sending it off to Terrence M. ...

By following the "nose" of fruit flies, Yale scientists are on the trail of new insect repellents that may reduce the spread of infectious disease and damage to agricultural crops. That's because they've learned for the first time how a group of genes used to differentiate smells is turned on and off, opening new possibilities for insect control. Just as in new drug development, researchers can target these or similar genes in other insects to create substances that make crops and people "invisible" to insect antennae. Without the ability to smell correctly, the insects ...

The GOES-13 satellite may be stationed in orbit over the eastern U.S., but it has a wide field of view from the eastern Atlantic to the eastern Pacific, and today it captured three tropical cyclones in one image.
At 1445 UTC (10:45 a.m. EDT) today, Sept. 22, the Geostationary Operational Environmental Satellite called GOES-13 captured Tropical Storm Lisa in the far eastern Atlantic, a developing tropical low in the south-central Caribbean Sea, and Tropical Storm Georgette in the eastern Pacific Ocean, making landfall in Baja California. The GOES series of satellites ...

Hurricane Igor may have transitioned into a post-tropical hurricane late yesterday, but when he approached Newfoundland, Canada and merged with an area of low pressure it resulted in heavy rainfall throughout the region. NASA satellites captured Igor's northern march toward the Labrador Sea yesterday.
NASA's Terra and Aqua satellites captured visible and infrared images of Hurricane Igor yesterday as he brought heavy rainfall into northeastern Canada. A visible image of Hurricane Igor over Newfoundland, Canada was captured by the Moderate Resolution Imaging Spectroradiometer ...
