很多人，跑步的和不跑步的，总有些担心，跑多了会不会伤膝盖？咱们坛里曾经有过讨论，多数已经知道跑步不会增加膝伤。这篇文章可以说是一粒定心丸。 文章节选如下，后面有链接： The new research surveyed 3,804 recreational runners who participated in the Chicago Marathon in 2019 or 2021 with questions from how many years they’d been running and their average running paces to whether they had family histories of arthritis.。。。。。 On average, runners who responded to the survey were just shy of 44 years old and ran 27.9 miles per week at 8 minutes and 52 seconds per mile. They’d typically been running for close to 15 years, although that number ranged from 1 to 67 years. Many respondents were running their first marathon while a select few had run dozens. Most fell somewhere in between. Thanks to the broad nature of the group surveyed — a departure from historical research focused on elite-level Olympians — the Northwestern researchers could analyze how runners’ arthritis risk changed according to their running pace, intensity and cumulative running history. Surprisingly, they found no association between an increased risk for knee or hip arthritis and the number of years someone had been running, the number of marathons completed, their weekly running mileage, nor their running pace. Given the survey respondents’ wide range of weekly mileages, paces, ages and cumulative years spent running, the results could apply to average runners who never get close to marathon-level distance, the researchers said. “Runners should be encouraged by our results,” Tjong said. “They refute the current dogma that long-distance running predisposes an individual to arthritis of the hip and knee.” Overall, 7.3% of marathon runners who answered the survey said they’d ever been diagnosed with hip or knee osteoarthritis. Hartwell cautioned against comparing this rate to a general population, given key differences in age and overall health. Even so, he said, “most doctors would recognize that on average, the incidence of arthritis is higher than 7% in a 44-year-old.” ................................ The “wear-and-tear” notion doesn't account for the ways running can benefit joint health and potentially offset deterioration, said Jeffrey Driban, an osteoarthritis researcher at Tufts University who wasn't involved in the Chicago Marathon study. The activity can improve muscle function around the joints and encourage the body to produce more of what's called synovial fluid, a viscous liquid that lubricates the joints. “It's concerning, the number of runners who are being advised by their physician to reduce or eliminate their running,” Driban said. “The evidence we have so far suggests that running, for most people, is a safe activity. We need to step away from this wear-and-tear philosophy.” ................................ Source Link:
