The problem of “food deserts” in many parts of the United States has gained attention in recent years. Now, researchers are highlighting a similar issue: play deserts. In a recent study, investigators at the University of Georgia found that in many areas of the country — particularly the South — families have few safe, free parks and playgrounds for their kids to enjoy. That’s a problem, experts said, because when kids lack those opportunities, they’re more likely to stay inside and stare at screens. It’s well known that there are communities nationwide where people have a hard time getting to a grocery store or any other source of fresh, nutritious food. Those places have been dubbed food deserts, and an estimated 10% of the United States falls into that dubious category. The new findings show that a similar percentage can be considered play deserts, according to researcher Lan Mu, a professor of geography at the University of Georgia, Athens (UGA). Many play-deficient counties are clustered in the Southeast, where a lack of options and the quality of existing play areas are often problems, the study found. The Southwest was another hotspot for play deserts, and a common issue was affordability: Some places require a membership or fee to enter. It’s not enough that parks or playgrounds merely exist in a community, said lead researcher Jue…  read on >  read on >

Need an activity to do with your kids on spring and summer days? Go to the park. Outdoor play is good for physical health, mental well-being and reduced stress in children, according to the American Academy of Pediatrics (AAP). “Whether it’s sunny or snowing, playing outside is good for children, physically and mentally,” said pediatrician Dr. Monique Jonae Soileau-Burke, president of AAP’s Maryland chapter. “Scientific evidence tells us that playing outdoors can improve health, and children love it,” she said in an academy news release. “On Kids to Parks Day [May 20], we encourage families to make plans to get their children out into nature for summer fun and well-being. Consider visiting a national, state or local park.” People who spend time in nature have lower levels of stress and depression. It’s also fun to be outdoors. The earlier you share nature with your baby, the more likely they are to develop a lifelong love of the outdoors, AAP notes. With an infant, you can take a walk through the trees with a stroller. Throw down a blanket to explore weather, bird songs, forest smells and plant textures while giving them some outside tummy time. Take your kids on a bike ride through the neighborhood or on a bike trail at a local or national park. It’s a good activity for all ages if you…  read on >  read on >

A new brain bank is accepting future donations from living athletes, in an effort to perform long-term research into the effects of sports-related concussion. The National Sports Brain Bank (NSBB) at the University of Pittsburgh will track the health of living participants on an annual basis, and will autopsy their donated brains after their death. “We want to follow prospective donors longitudinally while they’re still alive and get information from them about their sports participation, trauma, history, other medical history, any symptoms they may experience,” said NSBB Director Dr. Julia Kofler. “We can then correlate their clinical information with what we see down the road under the microscope, at the time of autopsy,” she said. Two former NFL stars — Hall of Fame running back Jerome Bettis and former Pittsburgh Steelers running back Merril Hoge — pledged at a news conference announcing the NSBB to stand among the first group of pro athletes who will participate in the brain bank. Bettis said he’s taking part as a way of giving back to professional football, and also potentially help protect his children’s health. “I’m a father and my son plays high school football. My daughter played high school basketball. She had multiple concussions,” Bettis said. “For me, it’s important that I be that role model to show that we have that job, if you will, as…  read on >  read on >

People with the rare heart disorder hypertrophic cardiomyopathy (HCM) can safely engage in vigorous exercise, according to new research. This finding could lead to fewer activity restrictions for people with this condition, which involves the heart muscle becoming thickened and enlarged. HCM is an inherited disorder that affects about one in 500 people worldwide. It is associated with sudden cardiac death in young people. Yet the U.S. National Institutes of Health-funded study found that those who exercised vigorously are no more likely to die or experience severe cardiac events than those who exercised moderately or not at all. “Based on these data, we’re learning that we don’t need to universally restrict HCM patients from participating in vigorous exercise, something that’s so important to all of us,” said study co-author Dr. Rachel Lampert, a professor of medicine at Yale School of Medicine, in New Haven, Conn. “Individuals with this condition should talk to a health care provider with expertise in HCM about getting back on the field, back in the pool and back on the court, if that’s what they want to do,” Lampert said in an institute news release. “Getting an expert evaluation is key to determining degree of risk for all HCM patients, and critical before going back to play.” To study this, the researchers recruited 1,660 people with HCM or who carried the…  read on >  read on >

Regular exercise has a long list of health benefits, and a new study suggests another one could be added: a lower risk of Parkinson’s disease. The study, of nearly 99,000 French women, found that those who were most physically active day to day were 25% less likely to develop Parkinson’s over three decades, versus women who were more sedentary. That does not prove that exercise, per se, is responsible, the researchers said. At the same time, they say it’s unlikely that the link reflects “reverse-causation” — women in the earliest stages of Parkinson’s being less likely to exercise. That’s because the study assessed the women’s exercise habits for up to 20 years before their Parkinson’s diagnosis. And since regular exercise clearly has benefits anyway, the findings could be seen as another motivator to get moving, said senior researcher Dr. Alexis Elbaz. “Physical activity has beneficial effects on many body systems, including the bones, heart and lungs,” said Elbaz, a research professor at the French national research institute INSERM in Paris. “And our findings show that physical activity might also contribute to preventing or delaying Parkinson’s disease.” Parkinson’s disease affects nearly 1 million people in the United States, according to the Parkinson’s Foundation. It is a brain disease that gradually destroys or disables cells that produce dopamine, a chemical that helps regulate movement and emotional responses.…  read on >  read on >

Lured by promises of bigger muscles and better performance on the field, many athletes and bodybuilders turn to anabolic steroids despite their well-known side effects, including increased risk for heart disease and mood issues. Now, two new studies show these harms may persist after athletes stop taking the synthetic hormones. The message is clear when it comes to the illegal use of anabolic steroids to boost muscle mass and enhance athletic performance: “Don’t do it,” warned study author Dr. Yeliz Bulut. She is a doctoral student at Copenhagen University Hospital in Denmark. In one study of 64 healthy men aged 18 to 50 who engaged in recreational strength training, 28 were using anabolic steroids, 22 were former steroid users and 14 had never taken steroids. Men underwent a test to see how much blood flowed to their heart muscles when resting and exercising. Both former and current steroid users showed poor blood flow to their hearts compared to those who have never used them. Most former users had stopped taking steroids more than one year before the study. In another study, three groups of men aged 18 to 50 answered questionnaires and gave blood to measure levels of the male sex hormone testosterone. This study included 89 current anabolic steroid users, 61 former steroid users and 30 men who had never used steroids. About three-quarters…  read on >  read on >

Fighting is par for the course in professional ice hockey, but a new study raises the question of whether it is shortening some players’ lives. The study, of hundreds of National Hockey League (NHL) players, found that those who were “enforcers” on the ice — that is, did a lot of fighting — tend to die at a younger age and from different causes than their peers. Of 45 players who died during the study period, enforcers were about 10 years younger at their deaths compared to other players. And the causes were disproportionately from suicide, drug overdose, car accidents, or, in two cases, degenerative brain disease. Experts stressed that the findings do not prove that frequent fights on the ice played any role in those players’ deaths. Release of the study comes midway through the second-round of the NHL’s Stanley Cup championship playoffs. The study used fights and time in the penalty box as proxies for players’ exposure to repetitive head impacts. There was no way to tell whether those who died had any brain injury. And even if they did, the researchers said, it would not be possible to draw a straight line between the injury and the cause of death. “This study is just showing associations, not cause and effect,” said lead researcher Dr. Charles Popkin, an orthopedic sports medicine specialist at…  read on >  read on >

A study of triathletes reveals certain body types perform better in certain climates. Taller, leaner runners with long limbs tend to excel in Ironman endurance events held in warm climates, whereas marathoners with stockier builds and shorter limbs perform better in colder climates, a Dartmouth College researcher says. Endurance athletes may want to consider competing in climates their body types are best suited to, said study author Ryan Calsbeek, a professor of biological sciences. Calsbeek observed that Allan Hovda, three-time winner of Norway’s Norseman triathlon, is stockier and shorter than one might expect of a successful triathlete. “I wondered if there was something about body shape that allowed him to do better in the cold and thought about the role temperature might play for this one guy who doesn’t look like your standard endurance athlete,” Calsbeek said in a college news release. Triathletes in these competitions do about 150 miles combined of running, swimming and biking. Calsbeek’s analysis of nearly 200 Ironman contestants over two decades suggests that running performance, specifically, is linked to how an athlete’s physique is adapted to shedding or retaining heat in certain climates. The study is among only a few that connect human physiology to what are known as Bergmann’s and Allen’s rules, which predict how animal species are distributed across various climates, Calsbeek said. These ideas are named after…  read on >  read on >

Androstenedione is one of those supplements that was peddled to athletes for years as a quick path to bulging muscles and high testosterone levels, but it comes with some serious side effects. Also known as “andro,” the dietary supplement was once touted to enhance athletic performance by stimulating muscle growth and boosting testosterone levels. But once it enters the body, it acts like a steroid and can pose similar health risks. In October 2004, President George Bush signed the Anabolic Steroid Control Act, which reclassified androstenedione from a supplement to an anabolic steroid, making it and other steroid-based drugs a controlled substance. They are currently banned in sports. This was because a small number of studies of androstenedione led the U.S. Food and Drug Administration to believe that its use may increase the risk of serious health problems because of its conversion in the body to the hormones testosterone and a particular form of estrogen. While over-the-counter androstenedione supplements are now banned, doctors can still prescribe it for medical purposes. According to a study published online recently in the journal Molecules, doctors can offer androstenedione shots for preventing or treating certain chronic diseases. Side effects of andro According to the Mayo Clinic, long-term use of androstenedione supplements by men can result in testicular atrophy, impotence and the development of female characteristics such as breast enlargement.…  read on >  read on >

Chronic tendon issues are a frequent source of pain and can limit activity. They become more common with age, weight and certain activities, and early and appropriate diagnosis by a doctor is critical to get the best outcomes. The Achilles tendon is the biggest tendon in the human body. It connects the calf to the foot, and it is responsible for push-off power. The tendon is critical for stability during standing, walking, running and other activities. During muscle contraction, the tendon functions as a rope. It has elasticity to generate the tension required to handle the force of six times a person’s body weight. What is Achilles tendinitis? Over time, the tendon can become strained, injured or inflamed. On a day-to-day basis, people put stress on their Achilles tendon. A healthy tendon will handle this stress, repair any “microtears,” and a patient will have no symptoms. But over time, for various reasons, the Achilles tendon will develop inflammation and microtearing that will outpace the body’s ability to repair and heal the damage, and the patient will develop symptoms including pain, discomfort, soreness and swelling. This is Achilles tendinitis, and I often treat such cases here at Yale Medicine Orthopaedics & Rehabilitation. In reality, Achilles tendinitis is not just inflammation of the tendon, as the name implies. Achilles tendinitis is the accumulation of degenerative changes in…  read on >  read on >
