Walking Faster May Help Reverse Frailty, Study Finds
中文总结
觉得运动太晚了吗?一项发表在《PLOS ONE》的新临床试验给出了不一样的答案:走快一点,而不只是走得多,能帮助老年人对抗衰弱。研究者在14个退休社区让165位平均79岁的老人参加为期4个月、每周3次的步行计划:一半人随意慢走,另一半被要求在安全前提下尽量走快。结果快走组近70%的人在至少一项衰弱指标上有改善,慢走组只有46%;快走组在6分钟步行测试中也走得更远。衰弱影响多达一半的老年人,会提高跌倒和住院风险。结论很简单:加快脚步,快走可能是健康 aging 最好的药之一。

全文参考
Here is a health story that proves it is never too late to start moving. A new clinical trial says walking faster, not just walking longer, can help older adults fight frailty. Scientists studied one hundred sixty-five older adults, with an average age of seventy-nine, in fourteen retirement communities. Everyone joined a four-month walking program, three times a week. Half walked at a relaxed, casual pace. The other half were told to walk as fast as they safely could. The results were clear. Nearly seventy percent of the fast walkers improved in at least one measure of frailty, compared with only forty-six percent of the casual group. They also walked farther in a six-minute fitness test. Frailty affects up to half of older adults and raises the risk of falls and hospital stays. The message is simple: pick up the pace. A brisk daily walk may be one of the best medicines for healthy aging.
