在多塞特的一家医院里，患有与关节有关问题的病人被医生建议把骑自行车作为一种治疗关节炎和减少髋关节置换手术等病症的方法。
据英国皇家伯恩茅斯医院(Royal Bournemouth Hospital)的顾问和整形外科医生罗伯•米德尔顿(Rob Middleton)说，定期骑自行车可以防止肌肉萎缩，从而延缓关节炎的发作，并减少其影响。
本周在医院的一次演讲中，米德尔顿概述了在那里进行的一项实验的结果，该实验表明，患者每天骑自行车的时间为30分钟。
其中一位参加这次演讲的听众Lindley Owen，Bournemouth和Poole Primary Care Trust的公共卫生顾问，他说:“这是一次开创性的演讲，是我20年来听到的最有趣的演讲。”
米德尔顿在他的网站中透露，他经常参加体育活动，他解释说，虽然骨关节炎经常被认为是与软骨和骨骼有关的问题，但它也可以被认为是与肌肉有关的问题。
他指出，一项研究发现，被允许自由运动的兔子不会患上关节炎，而那些被禁止运动的兔子则会患上关节炎。
该顾问补充说，尽管专业的自行车手经常表现出关节炎的症状，但只有当他们从比赛中退出，并降低他们的运动水平时，他们才会受到这种以疼痛为特征的情况影响。
根据米德尔顿的说法，定期参加非负重运动将比使用干细胞疗法或纳米技术来修复关节更有效。
欧文先生被伯恩茅斯的回声形容为“一个自行车爱好者”，他告诉报纸说:“罗布·米德尔顿所说的影响不仅对人们，而且对医疗保健的组织都有巨大的影响。”
“髋关节置换手术现在是发达国家最常见的手术，骑自行车可以挽救成千上万的人。”
“在一项试验的支持下，你不会看到NHS（公立医疗体系）的重大变化，但你会有证据支持这个想法。”
“在我的时代，我听过很多讲座，但我并不经常感到兴奋，但这个讲座是开创性的。”
兰斯·阿姆斯特朗基金会的Livestrong.com网站上的一篇文章强调了美国政府健康机构疾病控制与预防中心(CDC)的一项研究，该研究发现，定期骑自行车有助于预防骨关节炎，并帮助患者应对骨关节炎。
据体育科学家卡伦·哈比(Karen Hamby)在文章中提到，“与其他运动相比，骑自行车是一种相对温和的运动，可以帮助改善膝关节的灵活性和稳定性。”
英国的慈善组织关节炎研究（Arthritis Research UK）包括不同种类的种类自行车运动(链接是外部的)作为它筹款活动的一部分。
然而，并不是所有的医学专业人士都同意在关节炎的问题上骑自行车。正如我们两年前报道的那样，伊朗德黑兰医科大学的研究人员称，经常骑自行车的人在一开始就有可能患上这种疾病。

Patients at a hospital in Dorset who are suffering from problems related to their joints are being prescribed cycling as a way of heading off the onset of conditions such as arthritis and reducing the need for hip replacement operations.
According to Rob Middleton, consultant and orthopaedic surgeon at the Royal Bournemouth Hospital, cycling on a regular basis can prevent muscle wastage as delaying the onset of arthritis and reducing its effects, reports the Bournemouth Echo (link is external).
At a lecture at the hospital this week, Mr Middleton outlined the findings of a trial conducted there that saw patients cycle for 30 minutes a day on either a static or a moving bicycle.
One of those who attended the talk, Lindley Owen, who is a consultant in public health for Bournemouth and Poole Primary Care Trust, said “It was a groundbreaking lecture, the most interesting I have heard for 20 years.”

Mr Middleton, whose reveals on his website (link is external) that he regularly takes part in sportives, explained that while osteoarthritis is often thought to be an issue relating to cartilage and bones, it could also be considered as one related to the muscles.
He cited that one study had found that rabbits that were allowed to exercise freely did not develop arthritis, while those that were prevented from exercising did.
The consultant added that while professional cyclists regularly displayed signs of arthritis, it was only once they had retired from competition and reduced their levels of exercise that they tended to suffer the pain characteristic of the condition.
According to Mr Middleton, engaging regularly in non-load bearing exercise will prove more beneficial than the use of stem-cell treatment or nanotechnology for repairing joints.
Mr Owen, whom the Bournemouth Echo described as ‘a keen cyclist’ told the newspaper: “The implications of what Rob Middleton is saying have enormous impact, not just for people, but organisations that deal with health care.
“Hip replacements are now the most common operation in the developed world and this could save thousands.

“You won’t see a major change in the NHS on the back of one trial but you will have evidence backing up the idea.
“I have heard a lot of lectures in my time and it’s not often I get excited any more, but the lecture was ground breaking.”
An article on the Lance Armstrong Foundation’s Livestrong.com website (link is external) highlights a study by US governmental health body the Centers for Disease Control and Prevention (CDC) that found that regular cycling was effective in helping prevent osteoarthritis and dealing with its effects in sufferers.
According to sports scientist Karen Hamby, cited in the article, "In comparison to other exercises, cycling is a relatively knee friendly activity that can help improve knee joint mobility and stability."
The charity Arthritis Research UK includes a wide variety (link is external) of bike rides as part of its fundraising activities.
Not all medical professionals agree with the benfits of cycling when it comes to arthritis, however; as we reported two years ago, researchers at Iran's Tehran Medical University claimed that regular cyclists had a higher than average chance of contracting the condition in the first place.
