Can parallel use of different running shoes decrease running-related injury risk?
Due to the shear quantity of repetitive near-identical movements with minimal variability, distance runners are susceptible to cumulative micro-trauma - which manifests as running-related injuries (RRI). In order to break up the monotony of such loading, the aim of the current study was to investigate whether concomitantly changing shoes over a training cycle reduces the incidence of RRI.
264 recreational runners were followed prospectively over 22-weeks, whilst data was simultaneously collated regarding each individual's type of training, distance run and specific shoes used. The results determined that the parallel use of more than one pair of running shoes was a protective factor, whilst increased weekly volume of other sports correlated with a lower risk of RRI.
These findings suggest the variation of load applied to the musculoskeletal system in the form of multiple shoe use and participation in other sports may offer protection against repetitive overload injuries in distance runners. > From: Malisoux et al., Scand J Med Sci Sports (2013) (Epub ahead of print).
