Research Supports Sustained Exercise as Key to Heart Health

26.01.2010
The post-holiday paths to local gymnasiums are paved with the best of intentions.

After indulging in an assortment of goodies from Thanksgiving through the end of December, millions of Americans set New Year’s resolutions built on promises of slimming down and shaping up.

For many, the prospect of sweating at the gym five days a week or eliminating pizza as a food group loses its appeal after a week or two. When it comes to heart health, however, a radical lifestyle change isn’t required to affect positive change.

John Quindry, director of Auburn University’s Cardioprotection Research Laboratory, said far too many people associate hour-long elliptical machine sessions as the most effective means of building a healthy heart.

“There’s something about a new year where people muster up the courage to actually make some great claims and expectations for the year ahead, claims that most of the time go completely unfulfilled,’’ said Quindry, an assistant professor of exercise science in the College of Education’s Department of Kinesiology. “Just getting out and walking or jogging for the recommended 30 to 45 minutes most days is going to be enough to help.’’

Quindry said the point can’t be emphasized enough with February marking Heart Health Month. The American College of Sports Medicine and the Centers for Disease Control and Prevention both suggest 30 minutes of brisk walking as a benchmark for daily physical activity.

“They have what are called reduced exercise guidelines, which indicate even a little bit of physical activity can go a long way for health,’’ Quindry said. “It is overlooked by society. Despite established fitness and exercise standards, common expectations for a fitness program are all too often gauged by people like Lance Armstrong, people who have reached the pinnacle of athletic success.’’

Since the average person isn’t going to climb on a bicycle and compete in the Tour de France, however, Quindry said it’s important to tailor exercise regimens toward improving overall cardiovascular health. Through his animal-based laboratory research, Quindry and his collaborators have found that even a few days of exercise can provide a form of protection in the event of a heart attack.

In his lab experiments, Quindry has taken sedentary rats and exercised them through treadmill activity for three-day periods. After that period of moderate to vigorous exercise, the lab rats were subjected to experimentally-induced heart attacks, replicating a clinical heart attack in humans. Quindry has repeatedly found that the brief exercise regimen diminishes the severity of the heart attacks.

“The animal-based research has been structured so that it’s very clinically relevant,’’ Quindry said. “The animals we use exercise in proportion to the same intensities you and I would exercise for good health and fitness.

“Just three days of exercise overwhelmingly protects against heart attack damage,’’ Quindry said. “What we’re finding is that even a little bit of physical activity is more powerful than we once thought.’’

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
