瘋跑步30年 ＆ 膝蓋軟骨磨光光...(恕刪)
這兩件事並沒有直接證據顯示其聯!!
這篇美國國家衛生單位發表的文章落落長,
有許多有趣的正式科學研究的報告,
隨便列幾段看看...

Konradsen et al
compared 30 male runners who had been active at a competitive level with a group of matched controls. Weekly mileage, over at least four decades, averaged 21–42 kilometers per week. Pain at rest and during weightbearing activities, range of motion, and joint alignment were assessed. Weight-bearing anterior to posterior (AP) and lateral radiographs were assessed for changes according to the Ahlback scale. No significant difference in radiographic findings was found with regard to degenerative changes or osteophytes. The authors concluded that 40 years of running at 20–40 kilometers per week did not lead to osteoarthritic degeneration in individuals without underlying problems from pre-existing lower extremity injury.
40年間持續的跑步每週 21-42K 而下肢沒有嚴重受傷的人, 比對控制組的一般人, 並沒有發現運動或負重的能力以及骨頭更為退化或有骨刺.
Sohn and Micheli
surveyed 504 male and female college varsity cross-country runners and used 287 college swimmers as controls. Data regarding knee pain or alterations in daily activities due to pain was taken as indicative of OA. No significant difference was found between runners and swimmers.
大學越野跑步隊員和游泳隊員在膝蓋疼痛的研究比較中, 並沒有顯著差別.
Kujala, Kaprio, and Sarna
studied the incidence of hospital admission for OA of the hip, knee, and ankle in 1282 elite male athletes as compared to 777 matched controls. In the group of long-distance runners, 2.5% were admitted for knee arthritis as opposed to 1.3% of the general population. Long-distance runners were 1.84 times more likely to be admitted for OA (of the hip, knee, or ankle) than controls. The study did not report on hospital admissions for knee arthritis separately. It should also be noted that the average age at hospital admission for distance runners was 71.3 versus 61.2 years of age for the control group. When groups were controlled for body mass index (BMI), subjects with a higher BMI at age 20 and at the time of the study were 2.12 to 2.41 times more likely to be admitted to the hospital.
在長跑菁英與一般人就髖部, 膝蓋, 腳踝部位的研究比較中, 長跑菁英中有 2.5% 有膝蓋關節炎, 一般人有 1.3%; 長跑菁英中有髖部,膝蓋,腳踝關節炎的是一般人的1.84倍; 長跑菁英中因關節炎就醫平均是71.3歲, 一般人是 61.2歲. 本研究以體質指數BMI做分析, 當20歲時BMI比較大的人, 後來須就醫的可能性增加了兩倍多...
