The Effects Of Tempur Insoles On Ground Reaction Forces And Loading Rates In Running, Crystal Ruano*, Douglas Powell‡, Elizabeth T. Chalambaga*, Doug Renshaw*

International Journal of Exercise Science

Runners often experience over-use injuries. Ground reaction force (GRFs) patterns have been associated with these over-use injuries; however, it is not solely the magnitude of GRFs, but also the rate at which they are applied that lead to lower extremity injury. Many recreational runners will use over-the-counter insoles as a method of treating or preventing injury. Therefore, the purpose of this study was to examine the efficacy of two insoles on peak GRFs and loading rates. It was hypothesized that no differences in peak GRFs or loading rates would exist with the addition of two insoles during running. Twelve subjects …

International Journal of Exercise Science: Conference Proceedings

Introduction: Running is one of the most popular recreational sports in America with over 250 million regular runners. Recreational and competitive runners often experience over-use injuries including plantar fasciitis, Achilles tendinitis and stress fractures. Previous research has shown that the transmission of ground reaction force through the lower extremity leads to these over-use injuries; however, it is not solely the magnitude of vertical ground reaction forces, but also the rate at which these forces are applied that may lead to lower extremity injury. Many recreational runners will use over-the-counter insoles as a method of treating an injury or as a …
