exercise to build muscle mass and protect your heart
Dr. Joe Starnes, a kinesiology faculty member whose area of expertise and interest is cardio-protection, presented results from experiments in which he subjected endurance-trained rats to two different kinds of heart stresses and then examined the effects on the heart.
“A heart attack was one of the two kinds of stresses we tested, and when we simulated a heart attack in a rat that had completed a program of endurance training, the heart held up much better,” said Starnes. “However—and this was unexpected and a big surprise—if the stress was in the form of free radicals in the blood, the exercise-trained heart was actually less resistant than the sedentary heart.” Free radicals are a by-product of the cellular processes of burning fuel and are potentially harmful to the body. In addition to having Farrar, Tanaka and Starnes present research findings at the intersociety meeting, the Kinesiology and Health Education Department also hosted a reception for all conference attendees. About 200 members went to the reception and were given tours of the department’s labs, as well as the university’s sport facilities. Dr. Starnes reported that changes in the distribution and quantity of the enzyme nitric oxide synthase within the endurance-trained heart play a role in how it responds to specific stresses. This information is likely to be valuable in the treatment and management of cardiovascular disease, which has an economic impact of $368.4 billion in the United States according to the American Heart Association. |
“Our department is quite well-known among exercise physiologists,” said Farrar, “and many of the scientists were anxious to see our laboratories and talk to us about our research. All in all, this event was a wonderful opportunity for us to show off our work and network with some very distinguished and accomplished researchers. Some of our graduate students were able to meet these scientists, discuss their research and make valuable contacts for research opportunities in the future, and three of our department’s former doctoral students gave talks on how they pursued careers that built upon what they learned here at UT.”
The intersociety meeting, which occurs every four years, drew about 650 renowned scientists and researchers from around the world and represented members of the American Physiological Society, American College of Sports Medicine and Canadian Society for Exercise Physiology.
During the course of the three-day meeting, there were 12 symposia, representing 50 international speakers and papers, as well as 330 volunteered papers presented in poster sessions.
