Paragraph: Researchers from the University of Glasgow reported the results in the New England Journal of Medicine on Monday. They compared the causes of death of 7,676 Scottish men who played soccer with 23,000 similar men from the general population born between 1900 and 1976. Over a median of 18 years of study, 1,180 players and 3,807 of the others died. The players had a lower risk of death from any cause until age 70. However, they had a 3.5 times higher rate of death from neurodegenerative diseases such as Alzheimer’s or Parkinson’s. In absolute terms, that risk remained relatively small — 1.7% among former players and 0.5% for the comparison group. Former players also were more likely to be prescribed dementia medicines than the others were. The results “should not engender undue fear and panic,” Dr. Robert Stern, a Boston University scientist who has studied sports-related brain trauma, wrote in a commentary published in the journal. The findings in professional players may not apply to recreational, college or amateur-level play, or to women, Stern noted. “Parents of children who headed the ball in youth or high-school soccer should not fear that their children are destined to have cognitive decline and dementia later in life. Rather, they should focus on the substantial health benefits from exercise and participation in a sport that their children enjoy,” while also being aware of the risks of head-balling, Stern wrote. English Football Association chairman Greg Clark said “the whole game must recognize that this is only the start of our understanding and there are many questions that still need to be answered. It is important that the global football family now unites to find the answers and provide a greater understanding of this complex issue.” The association and players’ union sponsored the study. “We need to kick on now and understand what it means, because that’s all an awful lot we don’t know,” English FA chief executive Mark Bullingham said. “We don’t know if concussion was the cause or whether it was heading or whatever or whether it’s the old heavy ball or something entirely different.” But the association’s medical advisory group has not deemed it necessary to issue to change how the game is played, even reducing heading among younger age groups. “In youth football, you might want to reduce the likelihood of aerial challenges,” Bullingham said. “But our research shows this has already been reduced significantly over the years as we change to small size of pitches, move to possession-based football and now rolling substitutes.” Referees across all levels can stop games for three minutes to fully assess head injuries, but some experts believe that is not long enough. The English FA also is pushing soccer’s global lawmaking body for the introduction of concussion substitutes, with an additional player switch or as a temporary replacement. Campaigning to discover more about the long-term impact of head injuries in soccer has been led in England by the family of former England striker Jeff Astle, whose death at age 59 in 2002 was attributed to repeatedly heading heavy, leather balls. In 2017, a British study of brains of a small number of retired players who developed dementia highlighted the degenerative damage possibly caused by repeated blows to the head. ___ AP Chief Medical Writer Marilynn Marchione in Milwaukee contributed to this report. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

answer:
A study of former professional soccer players in Scotland finds that they were less likely to die of common causes such as heart disease and cancer compared with the general population but more likely to die from dementia. The results raise fresh concerns about head-related risks from playing the sport — at least for men at the pro level.


question:
Paragraph: HIIT can blast calories, build muscle and boost endurance with impressive efficiency in just 20 minutes a day, but the catch is finding the right level of intensity outside the comfort zone, fitness trainers say. Sean Bartram, author of the book “High Intensity Interval Training for Women,” said to find that level people should think about what it is like being chased by a rabid dog. “It’s just below that,” he said. “To gain maximum benefits you have to push your body to a place that’s almost uncomfortable.”   The American College of Sports Medicine predicts HIIT will be a top fitness trend in 2015. Bartram said people are drawn to it for its efficiency and almost endless variety of exercises. The bursts can be sprinting or spot jumps and the recovery can be rests or slower paced movements, he explained. “You could alternate 30 seconds of sprinting with 30 seconds of walking, or you could engage in a series of bodyweight exercises, such as push-ups, doing each for 30 seconds with 10 seconds of rest in between,” he said. Dr. Michele Olson, a professor of exercise science at Auburn University at Montgomery, Alabama, said it’s not high intensity unless the heart rate is elevated to near 90-plus percentage of its maximum. “Many people think they are engaging in HIIT but they are really doing traditional interval training, where the heart rate is around 75 to 85 percent of max,” she said. Maximum heart rate is about 220 minus age, according to the American Heart Association. Olson said that if done properly, HIIT can increase the effectiveness in losing abdominal fat and prompt favorable changes in cholesterol and insulin levels. “There is research showing that you can cut your exercise time nearly in half,” she said. About 20 minutes of HIIT can reap similar benefits of doing 35 to 40 minutes of moderate, steady-state cardio, she added, noting the training level must be intense. Hayley Zawadzki, personal training manager at New York Health and Racquet Club fitness centers, suggests that anyone starting HIIT should have a fitness analysis. “If you have a history of high blood pressure or medications, you cannot push to the absolute max,” she said. Claim: Key to High Intensity Interval Training found outside comfort zone.
answer:
With High Intensity Interval Training (HIIT), which consists of short bursts of intensive activity followed by short periods of  recovery, fitness experts say the harder the push, the greater the reward.


question:
Paragraph: The study tracked about 20,000 severely obese patients with Type 2 diabetes. Those who had weight loss surgery had a 40 percent lower chance of developing a heart attack or stroke in the five years following surgery compared to those who got usual care with diabetes medicines or insulin. For every 1,000 patients in the study who had surgery there were roughly 20 heart attacks or strokes compared to 40 such events per 1,000 who got regular care. More than 30 million Americans have diabetes, mostly Type 2 where the body loses the ability to produce or use insulin to turn food into energy. Other research has shown obesity surgery can reverse and even prevent diabetes. Taken together, it means doctors should discuss weight loss surgery more often, said study co-author Dr. David Arterburn of Kaiser Permanente Washington Health Research Institute in Seattle. Doctors usually mention insulin and pills, “but it’s not always brought up that weight loss surgery is another available treatment option,” Arterburn said. Researchers analyzed records from four U.S. health care systems: HealthPartners in Minnesota and Kaiser Permanente in Washington state, Northern California and Southern California. Results were published Tuesday in the Journal of the American Medical Association. The study can’t prove cause and effect because patients weren’t randomly assigned to get surgery. The researchers tried to match patients for gender, age, blood sugar levels and other factors. But other things they didn’t account for could have contributed to the surgery patients’ better results. Everyone in the study had a BMI, or body mass index, of at least 35. For instance, someone who is 5-foot-8-inches and weighs 230 pounds has a BMI of 35. Of the more than 5,300 who had surgery, most had gastric bypass, the most common type of stomach-shrinking operation. Some had gastric sleeve or gastric band procedures. The rest, nearly 15,000 people, had usual care. Obesity surgery can cost $20,000 to $25,000. Insurers are increasingly covering it, but some impose strict limits. The new findings suggest insurance coverage should be expanded for the right patients, Dr. Sayeed Ikramuddin of the University of Minnesota wrote in an accompanying editorial. Surgery is thought to help by affecting hormones, gut bacteria and other substances that affect how the body handles insulin and blood sugar. Weight loss without surgery also helps, but is difficult for many people to achieve. Most weight loss surgery today is done through small incisions. The dangers are similar to other surgeries, including a small chance of life-threatening complications, and some people need to have their surgeries repeated. ___ Follow AP Medical Writer Carla K.

answer:

Obesity surgery may dramatically lower the danger of heart attacks and strokes in patients with diabetes, new research suggests, reinforcing evidence that benefits extend beyond weight loss.
