Derivation Of An Age And Weight Handicap For The 5k Run, Paul M. Vanderburgh, Lloyd L. Laubach

The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems with such conventions include small numbers of runners within older age categories and the advantage given to the lightest runners within each weight category. We developed a 5K Handicap (5KH), a model that calculates an adjusted run time based on the inputs of actual 5K run time, age, and body weight for men and women. This adjusted time, then, can be compared between runners …

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 …

Escaping from predators often demands that animals rapidly negotiate complex environments. The smallest animals attain relatively fast speeds with high frequency leg cycling, wing flapping or body undulations, but absolute speeds are slow compared to larger animals. Instead, small animals benefit from the advantages of enhanced maneuverability in part due to scaling. Here, we report a novel behavior in small, legged runners that may facilitate their escape by disappearance from predators. We video recorded cockroaches and geckos rapidly running up an incline toward a ledge, digitized their motion and created a simple model to generalize the behavior. Both species ran …
