Keeping the beat going across USF
February 22, 2017
For today's entry we visited Campus Rec. and spoke with Lindsey Klein, Exercise Science graduate student and Fitness Program Assistant, to learn about ways that exercise can help to keep the heart healthy.
Top ways to keep a healthy heart?
“I think the main thing for a healthy heart would be to keep moving. A lot of the time, we have full-time positions where we’re stuck at a desk for many hours of the day, so I always make sure I get up one time an hour and make sure to always have a reminder set to get up, or have something scheduled every other hour so that I’m always up and moving. I also work out very frequently; exercise is very important for a healthy heart. Any cardiovascular exercise or resistance training I would recommend doing at least three times a week. Little things such as parking further, taking stairs, it all adds up [to benefit heart health].”
Keeping a routine vs. changing things up have more benefit?
“I think routines are better. I think routines work well for mostly everyone so you can have that mindset every day to plan out your agenda, when you can work out or when you can exercise, or to just get up and start moving. But, you don’t want to fall into a plan where you get bored, so switching it up every so often, every month or two, is definitely beneficial. The main thing with that is that you’re doing something you like because if it’s something you don’t like, you obviously don’t want to keep doing it.”

Interprofessional collaborations between health professionals and engineers can help improve patient care.
That’s what’s happening at USF. A nurse scientist and an engineer worked together to develop a smartphone application for patients with heart failure.
HeartMapp, created at USF, is an Android-based application for patients with congestive heart failure (CHF).
Ponrathi Athilingam, PhD, assistant professor at the USF College of Nursing, and Miguel Labrador, PhD, professor in the Department of Computer Science and Engineering at the USF College of Engineering, created HeartMapp, an Android-based application to help older adults with congestive heart failure (CHF) improve their self-care and reduce costly hospital readmissions.
“As a cardiology nurse of 25 years, I know that patients with heart failure, who must follow an intricate medication regimen and self-management practices at home to stay healthy and prevent getting admitted to the hospital, struggle with self-care,” Dr. Athilingam said. “After patients leave the hospital, they are alone. However, they do have a phone as a companion. So, we developed this easy-to-use, patient-centered technology to help them keep their heart health on track.”
Ponrathi Athilingam, PhD, assistant professor at the USF College of Nursing, and Miguel Labrador, PhD, professor in the Department of Computer Science and Engineering at the USF College of Engineering.
HeartMapp is a non-invasive mobile application that serves as a health coach for patients. The app has six modules allowing patients to assess their heart condition daily, monitor vital signs, perform breathing and walking exercises, take their medication, read educational information on heart health and review statistics in graphs that show their performance. The app also reminds patients every morning to check their weight, blood pressure and answer questions about their symptoms, thinking ability and mood.
“The app puts patients in green, yellow and red zones based on the status of their heart failure symptoms,” Dr. Athilingam said. “The green zone means their symptoms are under control. The red zone means they’re gravely ill and need to immediately go to the hospital. The goal is to identify patients when their symptoms decline to the ‘yellow zone’ to provide appropriate, early treatment and prevent hospital admissions."
HeartMapp, now copyrighted by USF, also provides patients with a web interface to access historical and real-time information about their physical condition using the Microsoft Wrist Band – to help with their physical activity and heart rate.
“HeartMapp is more than just a smartphone application, it’s a mobile information system,” Dr. Labrador said. “Besides the typical application technology, the system has different machines in the background receiving data from sensors and mobile devices, processing it with computer science algorithms and saving it in databases for patients, doctors, nurses and caregivers.”
Heart failure is a serious public health issue in the United States. According to Center for Disease Control and Prevention, more than five million people live with the condition. Heart failure occurs when the heart is not able to pump enough blood and oxygen to support other organs. Some symptoms include shortness of breath, weight gain, swelling and body weakness.
Supported by grants from the Florida High Tech Corridor and Draper Laboratory, the researchers have published several studies on HeartMapp in Wireless Health, Applied Nursing Research and Computers, Informatics, Nursing.
HeartMapp was also accepted into the National Science Foundation’s Innovation Corps (I-Corps) program, where researchers spent six months receiving real-world, hands-on experience that could help transition the mobile app out of the laboratory and into a commercially feasible product.
Dr. Athilingam and Dr. Labrador are currently working on a pilot study testing HeartMapp with nine patients from the USF Health Cardiology clinic. The patients, who are participating in the pilot study, find the app useful. A patient, who wishes to remain anonymous, thinks HeartMapp is a great tool that constantly keeps her informed about the state of her health.
“HeartMapp makes me self-aware,” the patient said. “It also allows me to keep track of my symptoms and be attentive of changes - pushing me to take action or check with my doctor regularly.”
Dr. Athilingam and Dr. Labrador are constantly updating HeartMapp with new features based on patients’ feedback. Their goal is to develop an efficient app that helps patients improve their overall health and well-being and reduce expensive hospital readmission rates.
“We’re hoping to get more funding to test the efficacy of HeartMapp to demonstrate that the app can improve patients’ condition and reduce hospital readmissions penalty fees,” Dr. Athilingam said. “When we show its efficacy, we could then potentially implement the product into cardiology clinics, commercialize it to companies and expand to iPhone and Microsoft operating systems.”
Both researchers are committed to HeartMapp. They will continue to work together as a team to improve the quality of life for patients with heart failure using the power of technology.
“In this day in age, there are difficult problems to solve,” Dr. Labrador said. “These problems need the knowledge and expertise of many different disciplines. If we don’t bring these disciplines together, we won’t be able to solve these complex problems.”
As every parent knows, children are always watching.
That is why, to address obesity in kids, it is critical that parents model healthy behaviors.
The influence of parents on their children’s exercise and eating habits is the basis of research being conducted by University of South Florida child and family studies experts Marilyn Stern, PhD, and Jennifer Bleck, PhD.
“Many parents who are overweight or obese think it’s too late for them. They just want to save their kids,” said Dr. Stern, professor in the Department of Child and Family Studies in the College of Behavioral and Community Sciences.
“It doesn’t work that way. A parent who doesn’t exercise and doesn’t eat well can say to the child, ‘eat your broccoli,’ but the child isn’t going to do it unless the parent eats broccoli, too.”
Childhood obesity — one of the leading causes of cardiovascular disease and a growing problem in America, where approximately one-third of children and teenagers are overweight or obese — has shown to be inextricably linked to parental obesity. “Predicting Obesity in Young Adulthood from Childhood and Parental Obesity,” published in the New England Journal of Medicine in 1997, found that, among children ages 3 to 5, the likelihood they would grow into obese adults increased from 24 percent if neither parent was obese to 64 percent if at least one parent was obese.
Those findings were reaffirmed in a 2004 study published in the Journal of Pediatrics, “Risk Factors for Childhood Overweight: A Prospective Study from Birth to 9.5 Years,” which identified parental weight as the “most potent risk factor” in childhood weight.
Just as the occurrence of childhood and parental obesity are connected, so too are successful treatments for the conditions.
In 2013, while at Virginia Commonwealth University, Dr. Stern co-authored “Parent Skills Training to Enhance Weight Loss in Overweight Children: Evaluation of NOURISH,” published in the journal Eating Behaviors. The article described the effectiveness of NOURISH, a program that provides parents, and parents only, with information on nutrition, exercise, the importance of mindful eating and family meals, and other topics. A National Institutes of Health-supported study found that children of NOURISH participants experienced significant reductions in their body mass indices, a measure of body fat based on weight in relation to height.
Since then, in work with teens, Latinos, African-Americans, and pediatric cancer survivors, Dr. Stern’s research has come to the same conclusion: Parental support and role modeling is key to children’s weight loss success.
Drs. Stern and Bleck, whose research also looks at the connections between eating disorders and attention deficit hyperactivity disorder, are now exploring local applications of weight-loss programs that target children by involving parents.
“Kids can only do so much on their own,” said Dr. Bleck, assistant research professor. “The support and participation of the parents is critical. Parents are the ones who buy the food. They control mealtime routines. They role model eating and activity behaviors.”
For parents interested in making healthy adjustments for both themselves and their children, Drs. Stern and Bleck offered a number of easy, free, everyday ideas:
- Take a walk — or do anything active — as a family: Throw the ball in the front yard. Go for a bike ride. Play a game of tag. Whatever the activity, shared exercise not only burns calories, it also builds familial bonds. “Kids are so enthusiastic about this because it means they get to spend more time with their parents,” Dr. Stern said.
- Introduce new vegetables at dinnertime: It’s a familiar refrain among parents — “My child is so picky!” Too often, when children protest tasting a new food, parents relent, allowing little Johnny or Suzie to avoid carrots or green beans. Persistence is key to helping children develop a balanced, nutrient-rich diet. “You have to introduce the new foods more than once. Don’t give up. It may take several times before the child will eat it. And, of course, role modeling is very important. The child has to see the parent eating vegetables — and enjoying them,” Dr. Stern said.
- Speaking of dinner, eat it together: Between soccer games and band practices, homework and the never-ending household to-do list, most evenings, it’s hard to get the entire family around the table at once. But at least a few times a week, make it happen, for everyone’s good. “Turn off the TV. Don’t allow cell phones. Make dinner a special time when the family comes together to support one another. This is when the positive role modeling takes place,” Dr. Stern said. “Parents should be seen eating healthily, and they should use family dinners as a time to set and discuss family weight-loss goals together. This creates that environment of support that children need.”
- Cut out the soda: Many sodas pack more than 150 calories per 12-ounce can. By cutting soda from their kids’ diets, and providing calorie-free water instead, parents can put a big dent in calorie consumption.
- Healthy habits aren’t just for waking hours: “Kids who don’t sleep well are more likely to be overweight and obese,” Dr. Stern said. Removing TVs, cell phones and other electronics from the bedroom creates a healthy sleeping environment.
Drs. Bleck and Stern added that even in families where obesity isn’t a problem, parents should still take care to model healthy habits.
Dr. Bleck said, “It’s about creating in children, early in their lives, a commitment and a motivation to be active and eat the right foods.”

In the Car, In Front of the TV: Prolonged Sitting Increases Cardiovascular Risk
Sitting Increases Cardiovascular Risk
When it comes to heart health, advice abounds on the benefits of physical activity.
Just as important, but not always as emphasized, said University of South Florida Exercise Science Program Professor Candi Ashley, PhD, is the importance of limiting physical inactivity — all those hours spent sitting at the office, in the car, or on the couch.
“The new message is that even if you do get the American Heart Association’s recommended 30 minutes a day of exercise, you can’t sit around the rest of the time,” Dr. Ashley said. “You have to get up and move to reduce the risk of cardiovascular disease.”
Exercise Science program graduate student Brittany Dutkiewicz uses an electrocardiogram test, or EKG, to show undergraduate student Jaevan Burke how his heart reacts during use of a treadmill. Students in the Exercise Science program study both the benefits of physical activity and the detriments of inactivity on heart health.
A 2008 article in the journal, Current Cardiovascular Risk Reports, “Too Little Exercise and Too Much Sitting: Inactivity Physiology and the Need for New Recommendations on Sedentary Behavior,” concluded that those who sit for prolonged periods are at increased risk of cardiovascular disease and other conditions, including diabetes and obesity, even if they also meet daily exercise recommendations.
“What the research shows is that the negative physiological consequences of sitting are separate from the effects of not getting enough exercise,” said Dr. Ashley, whose students include aspiring strength and conditioning coaches, physical therapists, cardiac rehabilitation specialists, and corporate fitness professionals.
“It’s important for my students to understand this, so that they will be ready to educate those they encounter in their careers about the importance of limiting time spent sedentary.”
Just how much time does the average person spend sitting or lying down? According to a 2012 review, “Too much sitting — A health hazard,” published in Diabetes Research and Clinical Practice, as much as 68% of adults’ total waking hours are spent in sedentary positions, be that commuting to and from work, sitting behind a desk, watching TV, or playing video games.
In a society increasingly geared toward sedentary lifestyles, individuals have to be deliberate about incorporating routine physical activity throughout their day. Dr. Ashley suggested:
· Take the stairs instead of the elevator.
· Park in the row farthest from the entrance.
· Use the bathroom farthest from your desk.
· Rather than emailing or calling your colleagues, walk to their desks.
· Stand while on telephone calls.
· Use a stand-up desk.
“If you can sit instead of lie down, sit. If you can stand instead of sit, stand. Take frequent breaks throughout the day and walk at least 200 steps during those breaks. Anything that increases muscle activation and energy expenditure, do it. It will reduce your risk of cardiovascular disease,” she said.
One of Dr. Ashley’s students is Brittany Dutkiewicz, a first-year graduate student pursuing her Master of Science in Exercise Science, who is planning a career as a cardiac rehabilitation specialist. When she enters the professional world, she said, she will emphasize the impact even short bursts of movement can have on her patients’ health.
“It’s never too late to exercise,” she said. “A patient can start with 10 minutes a day and it will make a difference.”

USF Health experts: Ten ways to keep your heart healthy
Heart disease is the leading cause of death in the United States. According to American Heart Association (AHA), more than 6 million adults currently live with heart disease.
The number of people living with the disease is only expected to rise. AHA data shows that, by 2030, more than 8 million people could be diagnosed with heart disease.
The numbers are alarming. But, taking basic daily steps may help prevent or reduce heart disease and heart attack.
USF Health medical experts on cardiovascular disease weigh in - providing ten things people can do to keep their heart healthy. They suggest to:
Vishal Parikh, MD, fellow of the Department of Cardiovascular Sciences at USF Health Morsani College of Medicine, says moderate exercise for at least 30 minutes a day can lower the risk of obesity, high blood pressure, high cholesterol and diabetes.
Smoking increases the risk of heart disease and heart attack, says Amy Alman, PhD, assistant professor in the Department of Epidemiology and Biostatistics at the USF College of Public Health. “So, say no to smoking,” says Dr. Alman.
Maintain a healthy diet
“A bad diet can put a strain to your heart,” says Ponrathi Athilingam, PhD, assistant professor of cardiology at USF College of Nursing. She suggests considering healthy foods such as fruits, vegetables, whole grains, fish, poultry, lean meats, and nuts to help lower the risk of heart disease. She also recommends eating foods with low trans-fat, saturated fat or sodium.
Dr. Parikh says that stress adds strain to the heart. Constant stress causes behaviors that increase heart disease risks including smoking, excessive alcohol, physical inactivity and lack of sleep. So, he says, “It’s important for people to identify triggers andpractice relaxing techniques such as meditation. Something just as simple as laughing may help combat stress.”
Advanced genomic monitoring/testing
Kevin Sneed, PharmD, dean of the USF College of Pharmacy, said advanced genomic testing and monitoring, which provides an assessment of cardiovascular genes, helps detect any genetic abnormalities early. “This type of technology would provide awareness, and, most of all, give information for a more targeted intervention to prevent future complications,” says Dr. Sneed.
Maintain a balanced weight
Excessive weight gain increases the risk of cardiovascular disease. According to Center for Disease Control and Prevention, weight gain leads to high cholesterol, high blood pressure and diabetes. “To keep the body in check, remain physically active and, above all, consume whole foods rather than processed foods,” says Mary Soliman, PharmD, assistant professor at USF College of Pharmacy.
Get regular exams
USF Health cardiovascular experts suggest that having regular heart screenings is important – checking the heart rate, blood pressure, body fat and blood sugar. They believe regular screenings keep people informed, which ultimately help prevent heart disease.
Know family history
Knowing about the family history is important. Having a relative or family member suffering from heart disease, greatly increases one’s risk. “If you have a family history of heart disease or a personal history of heart health risk factors (smoking, obesity, high blood pressure and cholesterol), you may just need to be more diligent in monitoring your heart health,” says Gregory M. Gutierrez, PhD, assistant professor at the USF Health School of Physical Therapy and Rehabilitation Sciences.
Maintain a healthy lifestyle
Keeping an overall healthy lifestyle is the secret to a healthy heart. USF Health experts all agree that lifestyle is key to lowering the risk of heart disease. Exercising, eating healthy, avoiding smoking and second hand-smoking and managing stress, lead to better heart health.
What women need to do
Heart disease causes, symptoms and outcomes may be different in women than in men, says Theresa Beckie, PhD, professor and cardiovascular health researcher at USF College of Nursing and Department of Cardiovascular Sciences in the USF Health Morsani College of Medicine. “Women represent a particularly high-risk phenotype. So women, especially young women, need to pursue aggressive measures to reduce risks with daily physical activity, a healthy dietary pattern, and stress management,” says Dr. Beckie.
USF Health’s cardiovascular team of faculty, researchers, doctors, nurses, physical therapists, pharmacists and public health professionals continue to develop top-quality research, education and state-of-the-art clinical care to make life better for patients suffering with heart disease.
