Exercise helps keep our gut microbiota healthy. Researchers found that exercise of moderate duration (more than 150 minutes per week) increased the diversity of the gut microbiome. How long a person exercises is more important than the intensity of the exercise for improving gut microbes. Since a poor diet can still outweigh the beneficial influence of exercise on gut microbes, it is important to also maintain a healthy weight.
运动有助于保持我们的肠道菌群健康。研究人员发现，中等强度（每周超过150分钟）的运动能增加肠道微生物群的多样性。若想改善肠道微生物，一个人能否持之以恒地保持运动习惯比运动时的强度来得更重要。由于不良饮食带来的有害影响仍然大于运动对肠道微生物的益处，因此保持健康的体重也是十分重要的。

Walking May Help Knee Osteoarthritis
A multiyear study has found that among participants with knee osteoarthritis, those who walked for exercise had a 40% decrease in the likelihood of experiencing frequent knee pain. On X-ray, those who walked also showed less severe disease. This suggests that walking may help reduce symptoms of knee osteoarthritis and slow down the destruction of the joints.
一项多年的研究发现，在患有膝关节炎的研究对象中，经常步行锻炼的人士出现频繁膝关节疼痛的可能性降低了40%。X 光片也显示，经常步行的人士即使罹患疾病，病情亦较不严重。这表明步行可能有助于减轻膝关节炎的症状，并减缓关节的受损进程。
