I currently sitting in Toronto airport waiting for a flight, so will not say anything much on this:
The effects of barefoot and barefoot inspired footwear on tibiofemoral kinetics during running
Human Movement. ISSN (Online) 1899-1955, DOI: 10.1515/humo-2016-0022, October 2016
Purpose. The current investigation aimed to examine the effects of running barefoot and in conventional and barefoot inspired footwear on the loads borne by the tibiofemoral joint.
Methods. Fifteen male participants ran at 4.0 m/s over a force platform whilst running barefoot, in barefoot inspired footwear and also conventional footwear. Lower body kinematics were collected using an eight camera motion capture system. Peak tibiofemoral force, peak tibiofemoral stress and tibiofemoral load rate were extracted and compared between footwear via one-way repeated measures ANOVA.
Results. The results showed that tibiofemoral instantaneous load rate was significantly lower in conventional (106.63 BW/s) in comparison to barefoot (173.87 BW/s), Vibram five fingers (160.17 BW/s), Merrell (155.32 BW/s), Inov-8 (167.79 BW/s), and Nike free (144.72 BW/s).
Conclusions. This indicates that barefoot and barefoot inspired footwear may place runners as increased risk from running related tibiofemoral pathologies.
After all, there is not much I can say (I have not read the full text). It speaks for itself. Yet another study telling us the opposite of all the propaganda and rhetoric of recent years from the fan boys. Next.
As always, I go where the evidence takes me until convinced otherwise …. and add this study to all the others that show barefoot/minimalist does not decrease impact loading paramaters.
