New research offers up some good news for diehard marathon runners: You don’t necessarily have to give up running if you are experiencing hip or knee pain. Contrary to widespread opinion, running marathons does not increase your risk for developing hip or knee osteoarthritis, the wear and tear form of the disease, a new study of seasoned Chicago marathoners showed. “You don’t develop knee or hip osteoarthritis simply because of how fast you run or how many miles you put on your body,” said study author Dr. Matthew James Hartwell, an orthopedic surgery sports medicine fellow at the University of the University of California, San Francisco. So, what does increase a runner’s risk for hip or knee arthritis? Basically, the same things that up these risks in non-marathoners, Hartwell said. This includes advancing age, family history of hip or knee arthritis, and previous injuries or knee surgery, as well as higher body mass index (BMI), a measure of body fat based on height and weight. For the study, more than 3,800 Chicago marathoners (mean age: nearly 44) answered questions about their running history, including number of marathons, number of years spent running, and average weekly mileage. They also answered questions about known risk factors for knee and hip arthritis. Participants completed an average of 9.5 marathons, ran 27.9 miles per week, and had been running…  read on >  read on >

Returning to golf, tennis or pickleball after shoulder replacement surgery shouldn’t be too hard. Healing does take time, but within a few months most people can get back to play at their pre-surgery level without the pain that they experienced before, a pair of new studies show. “Recovery after both an anatomic and reverse shoulder replacement or from any shoulder replacement is identical,” said Dr. Jonathan Levy, director of the Levy Shoulder Center at the Paley Orthopedic and Spine Institute in Boca Raton, Fla., who led both studies. “Patients are protected for the first six weeks and allowed to stretch for the next six weeks, but not allowed to return to the sport for at least three months,” he said. On average, it took patients about six months to play at their former level, Levy said. “But they were given the green light beginning at around three months,” he added. Recovery after shoulder replacements is relatively straightforward, Levy said. “It’s not an extraordinarily painful recovery,” he said. “If people are taking pain medication, it’s for a very short time. It’s just going through the stages of recovery where you go through healing, stretching, and then strength recovery and return to activity.” The first study included 69 golfers who had shoulder replacement surgery. Of this group, 36 returned to the golf course six months after surgery…  read on >  read on >

Fewer high school athletes are getting hurt playing sports, but those who do are more likely to suffer severe injuries that require surgery or a timeout from their chosen sport, new research shows. Which teens are most at risk? Those who participate in football, girls’ soccer and boys’ wrestling, the study authors found. Knee and ankle sprains and strains, along with head injuries such as concussions, were the most common injuries seen. Exactly why injuries are becoming more severe isn’t fully understood, but having kids specialize in sports too early may play a role. That can lead to an increase in overuse injuries, overtraining and burnout, said study co-author Jordan Pizzarro, a medical student at George Washington University School of Medicine and Health Sciences, in Washington, D.C. Still, the new data isn’t a reason for kids to stop playing sports. “Sports build endurance and stamina and help with growth and maturity,” Pizzarro said. Instead, parents should talk to the school or coach about pre-season training programs that may help stave off injuries among young athletes. For the study, the researchers tapped into 2015 to 2019 injury data from 100 high schools. These schools have athletic trainers who report injuries for five boys’ and four girls’ sports. Overall, there were 15,531 injuries that occurred during 6.8 million athletic exposures. (An athletic exposure is defined as one…  read on >  read on >

New research offers hope to elite athletes who have genetic heart conditions but still want to play sports. In the new study, after a follow-up of seven years, researchers found that 95% of athletes with a diagnosed and treated genetic heart disease had no disease-triggered cardiac events. These would have included fainting or seizures, implantable cardio-defibrillator (ICD) shocks, sudden cardiac arrest or sudden cardiac death. The researchers said the study was the first to assess the risk of potentially life-threatening arrhythmias (irregular heartbeat) among National Collegiate Athletic Association Division I and professional athletes with heart conditions that can increase the risk of sudden cardiac death, such as hypertrophic cardiomyopathy (HCM) and long QT syndrome (LQTS). Although people who have these heart conditions are often advised to avoid vigorous exercise and many are disqualified from sports, the findings suggest that may not be necessary. “This initial data set offers a story of hope and encouragement,” said Katherine Martinez, who conducted the study as an intern in the Mayo Clinic Windland Smith Rice Sudden Death Genomics Laboratory. “With shared decision-making and appropriate risk stratification by an expert, we expect anybody of any age can live and thrive despite their diagnosis.” For players and fans alike, witnessing an athlete experience heart trouble can be traumatic, such as when Buffalo Bills safety Damar Hamlin suffered cardiac arrest during a…  read on >  read on >

You can keep an arm in a cast from wasting away, researchers say, by working out your free arm. A small group of young men who performed eccentric contraction exercises with one arm — lowering a dumbbell in a slow and controlled motion — saw a 4% strength improvement in the other arm, even though it was immobilized by a cast at the elbow. Another group assigned to perform concentric contraction exercises — lifting a dumbbell — only lost about 4% of muscle strength in their immobilized arm, the study results showed. By comparison, a “control group” that did no exercises suffered a 15% decrease in their immobilized arm during the three-week study. It was already known that gaining muscle strength in one limb through resistance training will transfer to the same muscle on the opposite side of the body, said lead researcher Ken Nosaka. He is head of exercise and sports science at the Edith Cowan University School of Medical and Health Sciences, in Australia. “This is known as the cross-education effect,” Nosaka said in a university news release. “The key aspect of this study is one particular type of muscle contraction proved most effective.” For the study, 36 young men had their non-dominant arm immobilized by a cast at their elbow joint for three weeks. They were then split into three groups evenly:…  read on >  read on >

Playing sports can be good for kids of all abilities. A leading medical organization offers some tips for getting children involved, while helping keep them safe and injury-free. “We encourage children to play a variety of sports, both to increase their enjoyment over time and to avoid injuries we often see with overuse,” said Dr. Alison Brooks, chair of the American Academy of Pediatrics (AAP) Council on Sports Medicine and Fitness. “Parents can play a big role in influencing their children to play sports that are appropriate for their age, development and physical abilities,” Brooks explained in an AAP news release. Sports help kids stay fit and feel good about themselves, the AAP noted. Pediatricians also encourage young people with disabilities to participate in sports, recreation and physical activities whenever possible, the academy added. Among the many benefits of playing sports are improved physical and mental health; better social skills and relationships; enhanced well-being and self-esteem; and improved sleep and behavior. Still, all sports do have risks of injuries. Among the most frequent ones are sprains, which are injuries to ligaments; strains, which are injuries to muscles; growth plate irritation; and stress fractures. The AAP recommends having a doctor evaluate tenderness over a bone in a growing child even if there is minimal swelling or limitation in motion. Here are some tips to reduce the…  read on >  read on >

While the idea of getting 10,000 steps a day is bandied about as a good walking goal, that can be intimidating to some people, depending on how fit they are. Now, new research in adults between the ages of 70 and 90 finds that a much smaller number of steps can make a difference in heart health. It’s possible, according to researchers, that just 3,000 steps a day has benefits for heart health, and adding increments of just 500 more steps can also make a big difference. “Walking, I think, is just such a great activity that we can encourage people to do,” said study author Erin Dooley, an assistant professor in the Department of Epidemiology at the University of Alabama’s School of Public Health. “Getting up throughout the day and walking a little bit, even if it’s just around your house, any type of walking is helpful and beneficial.” Her team used data from the Atherosclerosis Risk in Communities study (ARIC) for this new study, with a sample of 452 adults who wore activity trackers on their waist for a few days and were then followed for about 3 1/2 years. The study grouped participants based on the number of steps they averaged. Those who were least active were getting about 2,000 steps. Those who were most active got about 4,500 steps. “That really…  read on >  read on >

A brisk 11-minute daily walk can help you live longer, a new University of Cambridge study reports. Researchers found that 75 minutes a week — 11 minutes daily — of moderate-intensity physical activity is enough to lower a person’s risk of heart disease, stroke and cancer. The investigators estimated that 1 in 10 early deaths could be prevented if everyone got that amount of exercise, which is half the level recommended by U.S. and British guidelines. “If you are someone who finds the idea of 150 minutes of moderate-intensity physical activity a week a bit daunting, then our findings should be good news,” co-researcher Dr. Soren Brage, of the Medical Research Council at the University of Cambridge in the United Kingdom, said in a university news release. “Doing some physical activity is better than doing none,” he added. “This is also a good starting position — if you find that 75 minutes a week is manageable, then you could try stepping it up gradually to the full recommended amount.” Cardiovascular diseases (heart disease and stroke) were the leading causes of death worldwide, responsible for nearly 18 million deaths in 2019. Cancers were responsible for 9.6 million deaths in 2017. To examine how much exercise could make a dent in those numbers, the researchers pooled and analyzed data from 94 large studies involving more than 30…  read on >  read on >

Causes of different kinds of dementia vary, but about 40% are affected by risk factors a person can influence through lifestyle choices. Two University of Michigan neurologists offer 10 tips for modifying those risks. Keep blood pressure in check. Dr. Judith Heidebrink, a neurologist who is co-leader of the Michigan Alzheimer’s Disease Research Center’s Clinical Core, recommends aiming for a systolic blood pressure (the upper number) of 130 mm Hg or lower from around age 40. This helps reduce risk of cognitive impairment, dementia, heart attack and stroke. Guard your hearing. Wear ear protection around excessive noise to reduce the risk of hearing loss, center director Dr. Henry Paulson urged. Use hearing aids, if needed. A recent study found that older adults who got a hearing aid for their newly diagnosed hearing loss had a lower risk of dementia in the following three years, he pointed out. Support efforts to reduce air pollution. “There is growing evidence linking air pollution — such as the gases and small particles emitted by cars and factories — to cognitive decline and dementia,” Heidebrink said. “Encouragingly, sustained improvements in air quality appear to reduce the risk of dementia.” Prevent head injuries. Wear proper gear when playing contact sports, including a helmet while biking. Don’t forget to use a seat belt in cars. Head injury can disrupt normal brain function.…  read on >  read on >

If you’re over 40, regular exercise may not only keep you fit — it might keep you out of the hospital, too, a large new study suggests. Researchers found that among nearly 82,000 British adults, those who regularly exercised were less likely to be hospitalized for various health conditions in the coming years. The list included such common ills as pneumonia, stroke, diabetes complications and severe urinary tract infections. The findings suggest that if middle-aged and older people added just 20 minutes of exercise to their daily routine, they could cut the risk of those hospitalizations by anywhere from 4% to 23% over seven years. Experts said the study expands on what people typically see as the benefits of exercise — like a trimmer body, improved fitness and healthier heart. “It could also help keep you out of the hospital. And that matters to people,” said Peter Katzmarzyk, a professor at Pennington Biomedical Research Center in Baton Rouge, La. Katzmarzyk, who was not involved in the study, said it aligns with what’s generally recommended to Americans to improve their health: Get at least 150 minutes of moderate “cardio” exercise, or 75 minutes at a vigorous intensity, each week. That means exercise that gets the heart pumping and works up a sweat: Moderate-intensity includes things like brisk walking, biking on level ground or yard work. Running,…  read on >  read on >
