You still see the claims being made in forums and blogs that heel striking and the cushioned supportive shoes increase stress on the joints and therefore those that heel strike and wear these shoes are going to get more osteoarthritis later in life. I have previously discussed the debacle that followed the release of one study that lead several barefoot running websites to claim that running shoes did cause osteoarthritis (they lied about the research).
If running shoes and heel striking did increase the risk of osteoarthritis and given the vast majority of runners heel strike and wear cushioning and supportive shows, then it stands to reason that runners would have more osteoarthritis than the general population if this was the case. Pretty much every study has shown that this is not the case! Yet the propaganda and rhetoric continues.
This study was first released in February and I been meaning to get to it for a while. Notably, this is a really big one:
Effects of running and walking on osteoarthritis and hip replacement risk.
Med Sci Sports Exerc. 2013 Jul;45(7):1292-7.
Running and other strenuous sports activities are purported to increase osteoarthritis (OA) risk, more so than walking and less-strenuous activities. Analyses were therefore performed to test whether running, walking, and other exercise affect OA and hip replacement risk and to assess the role of body mass index (BMI) in mediating these relationships.
In this article, we studied the proportional hazards analyses of patients’ report of having physician-diagnosed OA and hip replacement versus exercise energy expenditure (METs).
Of the 74,752 runners, 2004 reported OA and 259 reported hip replacements during the 7.1-yr follow-up; whereas of the 14,625 walkers, 696 reported OA and 114 reported hip replacements during the 5.7-yr follow-up. Compared with running CONCLUSIONS:
Running significantly reduced OA and hip replacement risk due to, in part, running’s association with lower BMI, whereas other exercise increased OA and hip replacement risk.
This one, unlike the previous ones that showed there was no increased risk for osteoarthritis from running, actually showed that running reduced the risk. Given that the vast majority of runners heel strike and wear supportive and cushioning running shoes, then its even clearer that they are not risk factors for osteoarthritis (not that there was any doubt before this study as the evidence was clear before it!).
Will this myth ever die? Or will it be, for example, something like the myth about vaccines causing autism: it does not matter how much research there is and how good the research is, the fan boys just don’t want to let it go?
As always, I go where the evidence takes me until convinced otherwise, and its time to put this myth to bed, but I said that last time.
