A marathon can be a daunting challenge, particularly for folks worried their hearts can’t stand the strain of running 26.2 miles. But these events are safer than ever for those with heart concerns, according to a new study published March 30 in the Journal of the American Medical Association. The risk of dying from cardiac arrest during a long-distance event decreased by half during the past decade, a new study says. It’s not that fewer runners are suffering heart problems. The rate of cardiac arrests that occur during full and half-marathons has remained unchanged, researchers found. “We continue to see media reports about unfortunate cases of cardiac arrest during long distance running events,” lead researcher Dr. Jonathan Kim, an associate professor of sports cardiology with the Emory School of Medicine, noted in a news release. However, a runner’s odds of surviving cardiac arrest are double what they were in the past, researchers said The sport has become more aware of the heart risks of running and is doing a better job preparing emergency response for stricken athletes, Kim said, based on interviews he’s had with survivors. “What we found was that every one of those people got hands-on cardiopulmonary resuscitation, but the vast majority also had immediate access to an automated external defibrillator,” Kim said. “That’s the difference.” The cardiac arrest survival rate at a…  read on >  read on >

Wearing a smartwatch might do more than track steps (or your texts) — it could be a powerful tool for helping people with type 2 diabetes stay active, a new study says. Participants were more likely to start and maintain an exercise regimen if they had a smartwatch providing them feedback and encouragement, researchers reported March 27 in the journal BMJ Open. Early results also indicate that they were achieving better control over their blood sugar levels and blood pressure, researchers report. “The results of this study can contribute to change the lives of many people around the world,” said researcher Ceu Mateus, a professor of health economics at Lancaster University in the U.K. “There are millions of people suffering from diabetes type 2 without access to non-pharmacological interventions with sustained results in the long term,” she added in a news release. “Our study shows that independently of the place where you live, your age, your ethnicity, your gender, or your income, there is an exercise program that suits you.” For the study, researchers recruited 135 people newly diagnosed with type 2 diabetes, and assigned half to wear a smartwatch paired with a health app on their smartphone. The app guided participants through a home-based physical activity program, using the watch to track their metrics. The program gradually increased their exercise to a target of…  read on >  read on >

Childbirth is an overwhelming accomplishment, but new mothers would do best not to rest on their laurels following delivery, a new guideline says. New moms should clock at least two hours a week of moderate to vigorous physical activity in the first months following birth, experts recommend. Two to four hours of exercise per week can keep a new mother healthy and reduce her risk of postpartum depression or anxiety, researchers wrote in the British Journal of Sports Medicine. Experts also recommend daily pelvic floor exercises to reduce the risk of urinary incontinence, as well as taking steps to improve sleep quality. “The weeks and months following birth are a period of abrupt changes in physiological and psychological health,” wrote a team led by Margie Davenport, a professor of kinesiology, sport and recreation at the University of Alberta in Canada. “Postpartum women and people are at increased risk of depression, weight retention, sleep disorders, diabetes and cardiovascular disease, especially if they experienced pregnancy complications,” the team wrote. “Such conditions have significant consequences on the short-term and long-term health and well-being of both the mother and the infant.” For the new guidelines, researchers analyzed data from 574 prior studies related to the health of mother and child following delivery. After consulting with a panel of new mothers, the research team selected 21 “critical” and “important” outcomes…  read on >  read on >

Folks frequently use their smartwatches to monitor their daily step count, aiming to get enough physical activity to improve their health. But smartwatches are tracking another measure of health that could prove even more important, a new study suggests. Smartwatches also capture a person’s average daily heart rate, and dividing that by their daily number of steps provides a more reliable measure of a person’s heart fitness than either number on its own, according to research to be presented in Chicago Saturday at a meeting of the American College of Cardiology. “The metric we developed looks at how the heart responds to exercise, rather than exercise itself,” lead researcher Zhanlin Chen, a medical student at Northwestern University Feinberg School of Medicine in Chicago, said in a news release. “It’s a more meaningful metric because it gets at the core issue of capturing the heart’s capacity to adjust under stress as physical activity fluctuates throughout the day,” he added. “Our metric is a first attempt at capturing that with a wearable device.” Generally, people are recommended to get 10,000 steps a day, although the number has varied from study to study. For this new study, researchers analyzed data from nearly 7,000 American adults who provided Fitbit data and their electronic health records to an National Institutes of Health research program. All told, the data reflected 51…  read on >  read on >

Dancing is known to lift the spirit, and a new study shows that Alzheimer’s disease patients respond to the rhythmic moves as well. Dance classes eased agitation in a small group of people with Alzheimer’s disease and other related dementias, researchers reported in the Journal of Alzheimer’s Disease. “This study highlights how movement-based interventions, like adapted dance, can be a meaningful way to improve both physical and emotional well-being for individuals with dementia,” researcher Rodney Guttmann, interim chair of biology with the University of West Florida, said in a news release. The three-month study took place in The Retreat, an adult day care fun by the Council on Aging of West Florida. “I was fortunate to witness the dancing intervention multiple times in person, and the activity was so well-run and fun that I could see morale, comprehension and physical ability among the participants improve in real time,” Council on Aging President and CEO Josh Newby said in a news release. For the study, researcher recruited four men and 12 women with Alzheimer’s disease or related dementia. Half of the participants were randomly assigned to take hour-long dance classes twice a week for three months, while the other half participated in activities without music like bingo, puzzles, crafts, cards and board games. Those in the dance group were taught six different routines like the box…  read on >  read on >
