  • Still a Champion Runner at 80: Do Elite Athletes Have an Anti-Aging Secret in Their Muscles?

    Released December 22, 2015 - Elite runners do not experience the muscle weakening associated with aging as non-athletes do. A new study published in American Journal of Physiology—Cell Physiology examines if their superb fitness is because their muscles have not aged.
  • Carbs, Not Fats, Boost Half-Marathon Race Performance, Study Finds

    Released December 15, 2015 - Recent studies have proposed that burning fat instead of carbohydrates will improve exercise performance because the body's fat reserve is much larger than its carbohydrates reserve. A new study in Journal of Applied Physiology reports the opposite, finding that muscles rely on carbohydrates as their fuel source during prolonged exercise.
  • New Study Explains Why You Bulk Up with Resistance Training, Not Endurance Training

    Released October 20, 2015 - Research published in Physiological Reports shows that resistance and endurance exercises activate the same gene, PGC-1a, but the processes stimulated for the muscles to adapt depend on the exercise type. The study offers insight into why the physical changes from resistance exercise are so different than from endurance exercise.
  • High-Intensity Training Delivers Results for Older Men—But Not for Older Women

    Released September 10, 2015 - High intensity training (HIT) is often recommended as a way to improve cardiovascular fitness in men and women, however, studies on these exercise regimens have focused on younger subjects. University of Copenhagen researchers looked at HIT effects in older males and females and found significant differences between men and women. They presented their results at the Physiological Bioenergetics conference in Tampa, Fla.
  • July APSselect Research Highlights

    Released July 1, 2015 - Brown adipose transplantation reverses type 1 diabetes in mice; heme oxygenase system as a potential therapeutic strategy for cardiovascular diseases; benefits of caloric restriction for muscle metabolism and mass during middle age; muscle signature of a champion sprinter are among this month’s selected articles.
  • Researchers Find Clues that May Predict Recovery Outcomes Following Total Hip Replacement

    Released May 4, 2015 - A cross-institutional team of researchers have identified a signaling substance (MuIS) that may predict patients who will have poor muscle regeneration outcomes following hip surgery. Testing patients for the presence of MuIS before surgery may help clinicians better plan for those who will need more intensive rehab post-surgery. This manuscript was chosen as an APSselect article for May.
  • Strength vs. Endurance: Does Exercise Type Matter in the Fight Against Obesity?

    Released April 23, 2015 - Researchers look at which form of exercise—strength, endurance or a combination of both—work best in tandem with diet to reduce weight and change body composition among obese study participants. Results are published in the Journal of Applied Physiology.
  • Caloric Restriction: A Fountain of Youth for Aging Muscles?

    Released April 22, 2015 - Caloric restriction has been studied as a way to increase longevity in animals. Now, researchers explore how it may positively affect muscle and find that aging muscles receive the most benefit.
  • “Ice It.” Why the Ubiquitous Advice Isn’t Healing Your Injury

    Released March 30, 2015 - Does icing a serious bruise actually speed recovery time and assist in muscle repair? Researchers say no. Study results to be presented at the 2015 Experimental Biology Meeting in Boston on Monday, March 30.
  • Older Adults: Double Your Protein to Build More Muscle

    Released January 30, 2015 - University of Arkansas for Medical Sciences researchers find that older adults may need to double up on the recommended daily allowance of protein to efficiently maintain and build muscle. The article is published in the AJP—Endocrinology and Metabolism and is highlighted as part of the APSselect program.
