2016 Press Releases

  • Testosterone Levels Improve in Overweight, Obese Men after 12-Week Exercise Program

    Released November 4, 2016 - Twelve weeks of aerobic exercise significantly boosted testosterone levels in overweight and obese men, according to researchers from Tsukuba University and Ryutsu Keizai University in Japan. Increased levels were highest among men who exercised vigorously. The new findings will be presented at the Integrative Biology of Exercise 7 meeting in Phoenix.
  • Exercise during Pregnancy May Reduce Markers of Aging in Offspring

    Released November 4, 2016 - Exercise during pregnancy may be as effective in protecting the next generation from age-related health risks as efforts made during the offspring’s own adulthood, new research suggests. University of Kentucky researchers will present their findings at the Integrative Biology of Exercise 7 meeting.
  • Dad’s Preconception Exercise May Increase Obesity, Insulin Resistance Risk in Offspring

    Released November 4, 2016 - Fathers who exercise regularly before their children are conceived may program their offspring's genes with an increased risk for metabolic disorders, according to new research from East Carolina University. The surprising results, to be presented at the Integrative Biology of Exercise 7 meeting, point to the identification of epigenetic markers that may change the process of diagnosis and management of chronic disease.
  • Exercise May Shield Against the Health Fallout of a Weeklong Overindulgence

    Released November 3, 2016 - Previous studies show that as little as one week of overeating can impair glycemic control and insulin sensitivity. Just in time for holiday feasting, a new study by University of Michigan researchers finds that exercise can protect fat tissue from changes in inflammation levels and fat metabolism caused by a brief period of eating too many calories. Research will be presented at the Integrative Biology of Exercise meeting in Phoenix.
  • Regular Exercisers Still Face Health Risks From Too Much Sitting

    Released November 3, 2016 - People who meet recommended weekly physical activity guidelines are still at risk of developing chronic disease if they spend too much non-exercising time sitting, new research suggests. Peter Katzmarzyk of the Pennington Biomedical Research Center will present findings at the Integrative Biology of Exercise 7 meeting.
  • Interval Exercise Training Improves Blood Vessel Function in Older Adults

    Released September 27, 2016 - Researchers have found that interval exercise training (resistance-based and cardiovascular) improves endothelial function in older adults. Resistance interval training in particular could help reduce the risk of heart disease in adults with type 2 diabetes. The study is published ahead of print in the American Journal of Physiology—Heart and Circulatory Physiology.
  • MicroRNAs May Link Inflammation and Heart Disease in Obese People

    Released August 26, 2016 - Results from a new study suggest that small molecules known as microRNAs may be part of the pathway connecting inflammation with increased heart disease risk in obese people. The new findings will be presented at the American Physiological Society’s Inflammation, Immunity and Cardiovascular Disease conference.
  • Dad’s Fatty Diet Can Lead to Obesity, Metabolic Syndrome in Grand-Offspring

    Released August 1, 2016 - Researchers report on how paternal intake of a high-fat diet causes changes in genes that lead to generational obesity and metabolic dysfunction, including body weight and fat mass increases and changes in blood pressure, triglyceride levels and fat metabolism. However, these effects in offspring can be significantly improved or abolished by feeding lower fat diet to subsequent generations. The article is published in AJP-Endocrinology and Metabolism and was chosen as an APSselect article for August.
  • Study in Rats Finds Maternal Intake of Past-Its-Prime Fish Oil Linked to Newborn Death

    Released July 22, 2016 - Nearly 30 percent of newborn pups born to pregnant rats fed highly-oxidized (“off”) fish oil died within two days after birth, finds a new study by researchers at the Liggins Institute at the University of Auckland in New Zealand. The research is published in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology.
  • Extra Fat Does Not Act as an Insulator

    Released July 5, 2016 - Carrying excess fat does not contribute to a warmer body in obese mice, a new study on the insulating effects of fat finds. The article is published in the American Journal of Physiology—Endocrinology and Metabolism.
  • Early-Life Stress Causes Digestive Problems and Anxiety in Rats

    Released May 26, 2016 - Traumatic events early in life can increase levels of norepinephrine—the primary hormone responsible for preparing the body to react to stressful situations—in the gut, increasing the risk of developing chronic indigestion and anxiety during adulthood, a new study in the American Journal of Physiology—Gastrointestinal and Liver Physiology reports.
  • Study Shows How Atherosclerosis and Osteoporosis Are Linked

    Released May 5, 2016 - Patients with atherosclerosis are at a higher risk of osteoporosis. A new study published in the American Journal of Physiology—Endocrinology and Metabolism reports that atherosclerosis reduces the number of bone-forming cells, leading to loss of bone density. This study is highlighted as one of this month’s “best of the best” as part of the American Physiological Society’s APSselect program.
  • Fat Stunts Growth of Tobacco Hornworm Caterpillars

    Released April 4, 2016 - Tobacco hornworm caterpillars eating a high-fat diet are smaller than their counterparts eating a medium- or low-fat diet. New research presented at the Experimental Biology 2016 meeting found that fat decreased the caterpillars’ food consumption, leading to the smaller body size.
  • Review Article Uncovers Clues to the Causes, Risk Factors for and Prevention of Drowning Deaths

    Released March 17, 2016 - An international team of researchers have published an extensive review of scientific literature on factors involved drowning fatalities in the journal Physiology. They outline how the fear of drowning, fitness level, fatigue, intoxication and other factors can contribute to negative outcomes and highlight warnings for people who may be at increased risk of drowning, such as those with heart conditions.
  • Aging May Worsen the Effects of a High-Salt Diet

    Released February 9, 2016 -Age significantly impaired the ability of rats to get rid of excess sodium when exposed to a high-salt diet, according to research published in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology. Findings could have implications for salt consumption in the elderly; suggest older people could be at greater risk for the negative consequences of eating a high-salt diet.
  • Study May Explain Why Stroke Risk in Women Changes after Menopause

    Released January 19, 2016 - Overactive microglia—the brain’s immune cells—may worsen the damage from brain injury after stroke or head impact. A new study in American Journal of Physiology—Endocrinology and Metabolism reports that a compound produced from estrogen called 2-methoxyestradiol calms overactive microglia. The findings offer an explanation for why stroke risk in women changes after menopause and point to potential treatments for treating brain injuries in men and women.
  • Not the Weaker Sex: Estrogen Protects Women Against the Flu, Study Finds

    Released January 12, 2016 - A new study published in American Journal of Physiology—Lung Cellular and Molecular Physiology finds that the female sex hormone estrogen has anti-viral effects against the influenza A virus, commonly known as the flu. The study supports why the flu may hit men harder than women.
