Integrative Biology of Exercise 7: Thursday Meeting Highlights

Bethesda, Md. (November 3, 2016)—Leading experts will convene at the Integrative Biology of Exercise 7 meeting (Nov. 2–4 in Phoenix) to discuss current research and new findings on how exercise affects us at all stages of life, from preconception to old age. See today’s highlighted research abstracts below. Contact the APS Communications Office for full abstracts or to contact a member of the research team.

Having an Apple-Shaped Body May Affect Memory

EMBARGOED UNTIL Nov. 3, 8:30 a.m. MST: Visceral fat located around the midsection may impair cognitive function and memory. Researchers from the Medical College of Georgia studied inflammation and neuronal function in obese mice and found that memory suffered. However, losing visceral fat restored cognitive losses. Request the abstract.

How Exercise Protects Against Common Brain Disorders

EMBARGOED UNTIL Nov. 3, 8:30 a.m. MST: Regular exercise may help protect against common brain disorders, including Alzheimer’s disease, sleep deprivation and posttraumatic stress disorder. Researchers from the University of Houston found that rats showed less anxiety, depression symptoms and memory impairment after being exercised on a treadmill. Request the abstract.

When It Comes to Sprint Training, Does Track or Treadmill Reign Supreme?

EMBARGOED UNTIL Nov. 3, 1 p.m. MST: Researchers at the University of Texas at El Paso randomly assigned 11 runners to six weeks of sprint training on either the track or a high-speed treadmill. The researchers wanted to see how the methods affected sprint speed, aerobic fitness and body composition. At the end of the six-week trial, the research team found both track and treadmill effective in improving speed and aerobic power. However, only one caused a “significant decrease in percent body fat.” Request the abstract.

The Surprising Role of Stress on Performance for an Elite Ultramarathoner

EMBARGOED UNTIL Nov. 3, 5:15 p.m. MST: “Stress hormones, such as cortisol, often increase during exercise, and this can positively affect athletic performance. However, continual activation of this stress response system can be detrimental to the body,” wrote researchers from Northeastern State University in Oklahoma. The researchers looked at how stress response affected an athlete who won a 100-kilometer race in 2015, using saliva samples collected after race completion. “In contrast to what many studies of exhaustive exercise have shown, cortisol levels and alpha-amylase activity decreased after 100 kilometers in this runner compared to pre-race levels,” the researchers wrote. The results suggest that extreme athletes may have an edge. Request the abstract.

Physiology is the study of how molecules, cells, tissues and organs function in health and disease. Established in 1887, the American Physiological Society (APS) was the first U.S. society in the biomedical sciences field. The Society represents more than 10,500 members and publishes 15 peer-reviewed journals with a worldwide readership.



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.

Experts Convene to Discuss the Effects, Potential of Exercise throughout the Lifespan

Released October 18, 2016 - Hundreds of researchers on the leading edge of exercise science will meet at the Integrative Biology of Exercise meeting in Phoenix (Nov. 2–4). Symposia topics will cover brain cell stress responses, metabolic diseases, mitochondrial signaling, sedentary behavior, exercise and pregnancy, cardiovascular disease, aging, stem cells and more.
