Key to evolutionary fitness: Cut the calories
Charles Darwin postulated that animals eat as much as possible while food is plentiful, and produce as many offspring as this would allow. However, new research shows that, even when food is abundant, intake reaches a limit. Dr. Teresa Valencak will discuss the theory that animals actively limit their energy turnover to maintain a higher level of reproductive success over their lifetime at the Society for Experimental Biology Meeting on Wednesday, July 1.

What should a teenage girl do if she finds a lump in her breast?
If a lump is found in the breast of an adolescent girl, she often will undergo an excisional biopsy. However, breast cancer is rare in adolescents, and the vast majority of teenage breast lumps are benign. A recent study published in the American Journal of Roentgenology suggests that a breast ultrasound might eliminate the need for biopsy in many cases. (2009-06-25)

Aerobically unfit young adults on road to diabetes in middle age
Most healthy 25 year olds don't stay up at night worrying whether they are going to develop diabetes in middle age. But many should be concerned. Researchers at Northwestern have found young adults with low aerobic fitness levels are two to three times more likely to develop diabetes in 20 years than those who are fit. The study also shows that young women and young African-Americans are less fit, placing more of them at risk for diabetes. (2009-06-18)

Hatchery fish may hurt efforts to sustain wild salmon runs
Steelhead trout that are originally bred in hatcheries are so genetically impaired that, even if they survive and reproduce in the wild, their offspring will also be significantly less successful at reproducing, according to a new study published today by researchers from Oregon State University.

New study finds lowfat chocolate milk is effective post-exercise recovery aid for soccer players
Soccer players and exercise enthusiasts now have another reason to reach for lowfat chocolate milk after a hard workout, suggests a new study from James Madison University presented at the American College of Sports Medicine annual meeting. Post-exercise consumption of lowfat chocolate milk was found to provide equal or possibly superior muscle recovery compared to a high-carbohydrate recovery beverage with the same amount of calories. (2009-06-01)

Cardiovascular fitness not affected by cancer treatment
The cardiovascular fitness level of cancer survivors is not affected by many standard cancer therapies, say researchers from Georgetown University Medical Cancer. That is the finding of a new observational study to be presented today at the American College of Sports Medicine in Seattle. (2009-05-28)

Did the North Atlantic fisheries collapse due to fisheries-induced evolution?
The Atlantic cod has, for many centuries, sustained major fisheries on both sides of the Atlantic. However, the North American fisheries have now largely collapsed. A new paper in the open-access, peer-reviewed journal PLoS ONE from scientists at the University of Iceland and Marine Research Institute in Reykjavik provides insights into possible mechanisms of the collapse of fisheries, due to fisheries-induced evolution.

22-year study finds adults aren't active enough
A new study has sounded the alarm that adults are inactive over their lifespan and don't exercise enough during their leisure time. Published in the International Journal of Behavioral Nutrition and Physical Activity, the study is unique in that it collected information over two decades from the 1981 Canada Fitness Survey, the 1988 Campbell's Survey of Well-Being and from the 2002-04 Physical Activity Longitudinal Study of the Canadian Fitness and Lifestyle Research Institute.

Study: Vibration plate machines may aid weight loss and trim abdominal fat
New research suggests that, if used properly, vibration plate exercise machines may help you lose weight and trim the particularly harmful belly fat between the organs. In a study presented on Friday at the European Congress on Obesity in Amsterdam, scientists found that overweight or obese people who regularly used the equipment in combination with a calorie restricted diet were more successful at long-term weight loss than those who combined dieting with a more conventional fitness routine. (2009-05-08)

Lactate test made easy

Safe exercise for migraine sufferers
Many patients who suffer from migraines avoid taking aerobic exercise because they are afraid that the physical activity may bring on a serious migraine attack. Researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, have now developed an exercise programme that can improve fitness among migraine sufferers without aggravating this painful condition.

Surgical gel used to stop bleeding could confuse mammograms
A gel sometimes used during surgery to stop bleeding could cause misleading mammograms. Researchers reported seven cases in which a sealant called FloSeal, used during lumpectomies, mimicked malignant microcalcifications in follow up mammograms. Microcalcifications can be a sign of breast cancer. Researchers said they do not recommend FloSeal for lumpectomies. (2009-04-14)

Taking cues: Sometimes environmental cues can activate thrifty behavior

Study: Morbidly obese sedentary for more than 99 percent of day
A new study appearing in Clinical Cardiology examines the average fitness level of the morbidly obese (body mass indexes between 40.0 and 49.9). The findings show that the tested population was sedentary for more than 99 percent of the day and, on average, walked less than 2,500 steps per day -- far below healthy living guidelines of 10,000 steps per day. (2009-03-25)

Brain surgery on Monday, home on Tuesday
Norma Wooley checked into Loyola University Hospital on a recent Monday morning for brain surgery to repair a life-threatening aneurysm.

New research published in the international journal Chest, by Neil Eves, Ph.D., finds that people with chronic obstructive pulmonary disease who breathed a mix of 60 percent helium and 40 percent oxygen during a rehabilitation program were able to exercise longer and harder than those who breathed normal air. (2009-03-09)

It's in his smell
A female moth selects a mate based on the scent of his pheromones. An analysis of the pheromones used by the European Corn Borer, featured in the open access journal BMC Biology, shows that females can discern a male's ancestry, age and possibly reproductive fitness from the chemical cocktail he exudes. (2009-03-02)

Physical fitness improves spatial memory, increases size of brain structure
When it comes to the hippocampus, a brain structure vital to certain types of memory, size matters. Numerous studies have shown that bigger is usually better. Now researchers have found that elderly adults who are more physically fit tend to have bigger hippocampi and better spatial memory than those who are less fit. (2009-02-24)
