I was poking through the abstracts of presentations for the upcoming meeting of the American College of Sports Medicine the other night and came across one for a study comparing injury rates between traditionally and minimally shod US Army soldiers.Titled “Injury Risk and Performance among Soldiers Wearing Minimalist Running Shoes Compared to Traditional Running Shoes,” the study was Adidas ZX 850 Dames carried out by a team of researchers from the Aberdeen Proving Ground in Maryland led by Asics Gel lyte 5 Femme Tyson Grier. Among Nike Air Huarache Womens the co-authors is Bruce Jones, who was a member of the team that conducted a series of studies showing that assigning shoes to soldiers based on arch shape was no more effective than simply assigning them all stability shoes by default.It’s worth emphasizing that this is an abstract of a presentation, not a peer reviewed journal article, so it has not yet been vetted by the scientific community. But, since I am familiar with previous work from members of this group I suspect it will wind up in a journal soon.METHODS: Participants were men in a U.S. Army Brigade Combat Team (n=1332). Physical characteristics and Army Physical Fitness Test (APFT) data were obtained by survey. Fitness performance testing was administered at the brigade Adidas Superstar Herre and the types of footwear worn were identified by visual inspection. Injuries from the Nike Air Force 1 Dameprevious 2Adidas NMD Dame 4 months were obtained from the Defense Medical Surveillance System. Shoe types were categorized into 2 groups: TRS (cushioning, stability, motion control) and MRS. A T-test was used to determine mean differences between personal characteristics and fitness performance metrics by shoe type (MRS vs. TRS). Hazard ratios (HR) and 95% confidence intervals (95%CI) were calculated to determine injury risk.You’ll note that the study looked at a very large sample of over 1000 soldiers. I’m not entirely sure what criteria were used to differentiate minimal vs. traditional shoes, but I don’t fault the authors since an abstract rarely gets into that level of detail and I assume that information will come in the presentation or the journal article when it is published. I’m also not clear if the soldiers were wearing the particular Nike Air Max 90 Dames Roze shoe Nike Air Max 90 Femme Grise types for the entirety of the 24 month tracking period. A strength of the study is that they are not relying on self-reported injury information – it comes from the Defense Medical Surveillance System.In light of the post I wrote yesterday on shoe sales and what runners are wearing, it’s worth noting the discrepancy between minimal shoe use among the soldiers versus other shoe types. 17% were wearing minimal shoes, only 2% were wearing motion control. Minimal shoe use was not far behind use of traditional stability shoes (24%) in this military population.If you’re a minimalist advocate you might love the following statement from the results: “Soldiers wearing MRS were younger than those wearing TRS, performed more push-ups, more sit-ups, ran faster during the 2 mile run, excelled on the vertical jump test, performed more pull-ups,Nike Air Max 2017 Dames completed the 300 yard shuttle run faster, and scored higher on the Functional Movement Adidas Deerupt Womens Screening test.” I wonder how long it will take for this line to wind up in shoe company marketing materials. It’s important to remember that correlation does not equal causation, and this result does not mean that they excelled in these areas because they wore minimalist shoes. It could simply mean that younger, fitter, more athletic soldiers prefer minimal footwear.
