Minimalist footwear, shortened stride affect loads differently during running

June 7, 2016

Running in minimalist footwear and running with a shorter stride length are both associated with reduced knee loads, but the two approaches differ in their effects on loading at the ankle, according to research from the University of Calgary in Canada.

Excess weight affects foot loading, peak pressure even in young kids    

June 6, 2016

Weight loss may improve function By Katie Bell Overweight and obese children present with higher overall foot loading and a disproportional impact on the midfoot and longitudinal arch, with those as young as 1 or 2 years of age affected, according to research from Germany that may have implications for abnormal foot loading prevention in children. Lead author Steffen Müller, PhD, research associate at the University Outpatient Clinic, Sports Medicine & Sports Orthopaedics, at the University of Potsdam in Germany, remarked, “In our data we cannot really see a well-adapted gait strategy for these children [for foot loading] since no real compensation is visible. Therefore, it could be speculated that the obese children are not capable [of adapting] their gait sufficiently to extra weight, leading to higher and disproportional foot loading.” The study included 7575 children aged 1 to 12 years and examined foot-loading characteristics during gait
