Assessing the effectiveness of micro-spring technology to reduce initial and peak loading rates when integrated into running footwear

Abstract

Running has long been one of the world’s most popular recreational activities. The current total of European runners exceeds 80 million, approximately, 36% of 15�65-year-old European population. Running is one of the most widespread activities during which overuse injuries of the lower extremity occur (Hreljac, 2004). It has been estimated that up to 70% of runners will sustain an overuse injury during any one year period (Caspersen et al., 1984).
Previous work has shown that impact forces and high loading rates are linked to injury rates in runners (Davis, Bowser, & Mullineaux, 2010). Despite the apparent advances in footwear technology and the plethora footwear choices available, we are yet to see a reduction in
injury rates amongst runners.
