A major review of 217 clinical trials has identified aerobic exercises like walking, cycling and swimming as the most effective for reducing pain and improving function in knee osteoarthritis. The study, published in The BMJ, recommends these activities as the first-line intervention. Other exercises provide benefits but work best alongside aerobics.

Preparations are underway in Kalkar, North Rhine-Westphalia, for the „Locked Shields“ cyber exercise. 45 NATO and partner countries are training together to defend against AI-powered attacks. The exercise begins on Monday.

A new analysis suggests that varying exercise routines, such as mixing running, cycling, and swimming, may reduce mortality risk by 19 percent compared to less diverse workouts, even when total activity levels are similar. Researchers examined data from over 110,000 U.S. participants tracked for more than three decades. The findings highlight potential benefits of exercise variety, though they remain suggestive rather than conclusive.

Vibrating the Achilles and patellar (knee) tendons for 10 minutes before a short cycling task helped volunteers generate more power and reach higher heart rates without reporting greater exertion, according to a Université de Montréal-led study that examined how the brain interprets effort.

A Rutgers-led randomized trial reports that the diabetes drug metformin reduced several improvements that typically follow exercise training, including gains in blood vessel function, aerobic fitness and measures of glucose control.

Researchers have discovered that betaine, a metabolite produced by the kidneys, mimics many anti-aging benefits of exercise. The study, published in Cell, shows how sustained physical activity triggers a surge in betaine to reduce inflammation and rejuvenate immune cells. Oral betaine supplementation alone replicated these effects in animal models.
