Strength training may actually do more than just help build muscle. It could be even better than running when it comes to protecting against diabetes and unhealthy weight gain. In a recently published study using mice fed a high-fat diet, scientists at Virginia Tech found that both running and weightlifting improved blood sugar control, but resistance training was more effective at reducing body fat, improving glucose tolerance and lowering insulin resistance. Those factors all help prevent and manage type 2 diabetes. “We all want to live a long, healthy life,” said senior study author Zhen Yan, director of the Center for Exercise Medicine Research at Virginia Tech in Roanoke, Virginia. “We all know the benefits of regular exercise. There is plenty of evidence in humans that both endurance exercise, such as running, and resistance exercise, such as weightlifting are effective in promoting insulin sensitivity,” Yan explained in a news release. The findings were published online Oct. 30 in the Journal of Sport and Health Science.  To compare the two exercise types directly, researchers created a first-of-its-kind “weightlifting” model for mice.  The rodents in one group had a small shoulder collar attached to them and had to use it to lift a weighted lid to reach their food, mimicking a squat-like motion.  Another group of mice had free access to a running wheel.  A third group…  read on >  read on >

Exercise can help women with advanced breast cancer better withstand both cancer treatments and the ravages of the disease, a new clinical trial shows. A nine-month program of supervised aerobic and resistant exercise improved muscle mass and strength among women with advanced breast cancer, particularly in their arms and legs, researchers found. The women put on nearly 2 pounds of additional muscle mass within the first three months, compared to a control group that didn’t have exercise classes, researchers found. While muscle mass did decline over time, the women still had just under a pound of extra muscle after six months compared to the control group, researchers added.  “The results from our study are important since lean body mass is linked to better treatment tolerance, prognosis and overall health, and increased muscle strength correlates with improved quality of life and lower mortality risk,” said researcher Anne May, a professor of clinical epidemiology of cancer survivorship at the University Medical Center Utrecht in The Netherlands. “This supports the call for exercise, and specifically supervised exercise with a resistance exercise component, to be integrated as a standard component of cancer care for patients with metastatic breast cancer,” May added in a news release. For the study, researchers recruited 357 patients with stage 4 breast cancer between 2019 and 2022. The women were being treated in hospitals in…  read on >  read on >

Does the city you run in make a difference? Researchers say yes, it does. When marathon runners hit the wall or fall behind their goal pace, they often blame fatigue, weather or nutrition. However, a study from Brown University published in Sports Medicine suggests a less obvious, environmental culprit: air pollution. Researchers analyzed a dataset of 2.6 million marathon finish times from major U.S. races, including those in Boston, New York City and Los Angeles, spanning 17 years and matched it to estimated pollution levels from weather stations.  They found a direct link between slower average finish times and higher concentrations of fine particulate matter known as PM2.5. The data also showed that the fastest runners were more affected by this effect. PM2.5 refers to tiny pollutants smaller than 2.5 micrometers in diameter. These particles are often the focus of air-quality health advisories, because they can travel deep into the lungs and enter the bloodstream, causing inflammation and chest constriction, reports The New York Times. The study revealed a measurable slowdown tied to PM2.5 levels. For every increase of one microgram per cubic meter increase in these tiny particles, the average finish time for runners dropped. Men were 32 seconds slower for every one microgram/cubic meter increase. Women were 25 seconds slower for every one microgram/cubic meter increase. In other words, on a day with…  read on >  read on >

Home exercises can effectively ease knee pain caused by cartilage tears and arthritis, apparently with or without physical therapy, a new study says. The stretching and strengthening exercises provided about the same amount of pain relief whether or not a person got real or sham physical therapy, researchers reported Oct. 29 in The New England Journal of Medicine. “On average, participants in all groups reported moderately severe pain at the start of the study and much milder pain three, six and 12 months later,” lead researcher Dr. Jeffrey Katz said in a news release. He’s clinical director of the Orthopedic and Arthritis Center for Outcomes Research at Brigham and Women’s Hospital in Boston. As many as 40% of middle-aged folks and 80% of those with knee arthritis have tears in their knee cartilage, which is called the meniscus, researchers said in background notes. For the study, nearly 900 people with an average age of 59 were randomly assigned to one of three groups. The patients all had knee pain, arthritis and a meniscus tear. One group took part in a 25-minute home exercise program four times a week, guided by a video and pamphlets. The second and third groups got home exercise plus either real or placebo physical therapy. Those who got real or sham PT did have slightly greater pain improvement at six and…  read on >  read on >

Women benefit much more from exercise than men, reaping many more gains with considerably less work, a new study reports. With the same amount of exercise, women experience a three-fold reduction in their risk of death from heart disease compared to men, researchers reported Oct. 27 in Nature Cardiovascular Research. These results show that “one-size-fits-all” exercise guidelines are misguided, in that they assume both sexes derive the same benefit from the same amounts of exercise, researchers concluded. “Compared with male individuals, females derive equivalent health benefits with only half the exercise time,” wrote the research team led by Jiajin Chen, a research associate with the Xiamen University Institute of Cardiovascular Diseases in China. “The findings might have potential to encourage females to engage in physical activity.” For the study, researchers analyzed data collected on more than 85,000 participants in UK Biobank, a long-term health research project in the United Kingdom. The people in the study wore activity trackers on their wrists. Results showed that to reduce their risk of heart disease by 30%, men need to get 530 minutes of moderate-to-vigorous physical exercise each week. Women only need to exercise 250 minutes a week — less than half — to achieve a comparable benefit, researchers found. Overall, women who met the guideline target of 150 minutes of exercise weekly had a 22% lower risk of…  read on >  read on >

Fitness and calorie counting apps are meant to boost people’s spirits, helping them become healthier by tracking their progress. But many find them to be a complete downer and an utter detriment, a new study says. Some experience a sense of shame, disappointment, frustration and futility when using these apps, undermining their attempts to improve their health, researchers reported Oct. 22 in the British Journal of Health Psychology. “We found a lot of blame and shame, with people feeling they were not doing as well as they should be,” senior researcher Paulina Bondaronek, a senior research fellow at University College London, said in a news release. “These emotional effects may end up harming people’s motivation and their health.” For the study, researchers analyzed nearly 14,000 posts about five popular fitness apps on the social media site Twitter, prior to its rebranding as X. The apps were MyFitnessPal, Strava, WW, Workouts by Muscle Booster, Fitness Coach & Diet, and FitCoach. Most of the posts (nearly 8,500) related to MyFitnessPal, followed by Strava and WW (formerly Weight Watchers). Results showed that the apps often produced as much frustration as motivation. Users expressed: Shame at having to log “unhealthy” foods. Irritation at notifications to log calories or reduce sugar consumption. Disappointment at slow progress toward targets set by the apps. Skepticism at strict goals set by apps. Annoyance…  read on >  read on >
