https://medicalxpress.com/fitness-news/ en-us Latest health news and information about Fitness & Physical Activity Obesity can weaken the immune system's tumor-killing responses in lung cancer, leading to disease progression, but a new study by experts at Roswell Park Comprehensive Cancer Center reveals that exercise may reverse this effect. https://medicalxpress.com/news/2026-08-obesity-weakens-anti-tumor-immune.html Mon, 17 Aug 2026 12:40:07 EDT news706185962 Most individuals encounter their health primarily through an annual health screening, which provides a limited snapshot of their health status. A new study by the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), challenges the way we think about health and longevity by seeking to understand what occurs between those assessments, focusing on function rather than static markers and tracking how physiology changes moment to moment. https://medicalxpress.com/news/2026-08-professor-subject-longevity-biological-age.html Thu, 13 Aug 2026 11:40:01 EDT news705839287 Three minutes of sprinting can do something that 90 minutes of moderate exercise apparently cannot: dramatically reshape the molecular contents of the bloodstream. Rockefeller researchers comparing different intensities of exercise found that six sets of 30-second, all-out sprints altered nearly a quarter of the proteins measured immediately afterward. Moderate, continuous cycling for 90 minutes altered fewer than one-quarter of 1%. And while moderate treadmill running changed more proteins than cycling, it still altered far fewer than a quick sprint. https://medicalxpress.com/news/2026-08-minutes-sprinting-bigger-impact-moderate.html Thu, 13 Aug 2026 11:00:01 EDT news705833761 Taking the stairs could help you live longer—according to new research from the University of East Anglia and the Norfolk and Norwich University Hospital. The study, published today, suggests that climbing stairs significantly reduces the risk of dying from cardiovascular disease. https://medicalxpress.com/news/2026-08-stairs-early-death.html Wed, 12 Aug 2026 19:10:03 EDT news705671582 Anyone who has run while pushing a stroller knows stroller running can feel cumbersome and hard on the body. But does it increase the risk of injury? According to a new study from researchers at Penn State Berks, the answer appears to be no. https://medicalxpress.com/news/2026-08-parents-stroller-overuse-injury.html Wed, 12 Aug 2026 14:00:04 EDT news705588660 As a sophomore wide receiver who had just joined the USF football team, Jaden Alexis didn't expect a routine play to turn into a career-defining moment. During preseason football camp, Alexis had just sprinted up the sideline after catching a pass when a split-second collision changed everything. https://medicalxpress.com/news/2026-08-acl-injuries-early-ai-wearable.html Tue, 11 Aug 2026 18:20:02 EDT news705685923 In a study conducted at the Universities of Jyväskylä and Eastern Finland, more screen time since childhood was associated with better cognitive processing in adolescence. According to one of the researchers, we should not regard screen time solely as harmful. The most important thing is to find a balance between physical activity and screen time that promotes active thinking. https://medicalxpress.com/news/2026-08-screen-childhood-cognitive-adolescence.html Tue, 11 Aug 2026 14:00:05 EDT news705665472 Replacing 15 minutes of sleep or sedentary behavior with 15 minutes of movement was each linked to a 2% reduced risk of cancer, new UCL research has found. https://medicalxpress.com/news/2026-08-fifteen-minutes-movement-linked-cancer.html Mon, 10 Aug 2026 15:32:05 EDT news705594685 Not every disease announces itself with obvious symptoms. Some develop quietly, going unnoticed until they begin to take a serious toll on health. Metabolic syndrome (MetS) is one of them. Rather than a single disease, it is a combination of at least three conditions—including high blood pressure, high blood sugar, excess belly fat, high triglycerides and low HDL (good) cholesterol—that together raise the risk of heart disease, stroke and type 2 diabetes. https://medicalxpress.com/news/2026-07-equal-metabolic-syndrome.html Fri, 31 Jul 2026 12:40:06 EDT news704696757 Yoga is best known for improving flexibility, building strength and reducing stress. Research suggests it may also help ease symptoms of irritable bowel syndrome (IBS), a common digestive disorder that affects millions of people. https://medicalxpress.com/news/2026-07-yoga-relieve-bowel-syndrome-symptoms.html Thu, 30 Jul 2026 08:00:06 EDT news704613961 Researchers from the Universities of Hildesheim, Bonn and Freiburg have uncovered how human skeletal muscle responds to resistance exercise at the molecular level. Their findings provide new insights that could help optimize training programs for athletes, improve rehabilitation strategies and counteract age-related muscle loss. https://medicalxpress.com/news/2026-07-resistance-muscle-machinery.html Tue, 28 Jul 2026 16:00:06 EDT news704463602 An international team of researchers led by the Barcelona Institute for Global Health (ISGlobal) and the University of Bonn—with participation from the Barça Innovation Hub (BIHUB), FC Barcelona's medical department and the company Made of Genes—has developed a computer-based approach that improves injury prediction in elite women's soccer. The study, published in npj Digital Medicine, combines artificial intelligence, survival analysis, statistical calibration and decision theory to transform risk prediction into a useful tool for clinical and sports practice. https://medicalxpress.com/news/2026-07-cumulative-fatigue-emerges-predictor-women.html Tue, 28 Jul 2026 15:00:02 EDT news704463201
