STUDY DESIGN Case report. BACKGROUND The underlying mechanism of the changes in running mechanics after gait retraining is presently unknown. This case report assesses changes in muscle coordination and kinematics during treadmill running and step ascent in 2 female runners with patellofemoral pain after mirror gait retraining. CASE DESCRIPTION Two female runners with chronic patellofemoral...

The ability of peanut plants to adjust to wide plant-toplant spacing and the use of more precise mechanical planters have not been thoroughly exploited to reduce seeding rates. The magnitude of plant growth adjustment of two runner peanut cultivars to reduced seeding rate was studied in 1992 and 1993. A precision vacuum planter was used to plant the cultivars GK-7 and Southern Runner (SR) in si...

The economic value of participation sport has been reported to eclipse spectator sport significantly. However, scholars have acknowledged the relative lack of research on this important segment of the sport market. The purpose of this study was to analyze the relationship between runner identity and race sponsor effectiveness. Surveys were sent to participants in the Las Vegas Rock ‘n ’ Roll Ma...

Suppose k + 1 runners having nonzero constant speeds run laps on a unit-length circular track starting at the same time and place. A runner is said to be lonely if she is at distance at least 1/(k + 1) along the track to every other runner. The lonely runner conjecture states that every runner gets lonely. The conjecture has been proved up to six runners (k ≤ 5). A formulation of the problem is...

important activities of die-casting die design. In normal practice, determine therunner and gating designparameters. These parameters are simulations on a computer and dry runs on adie-casting machine These iterative activities increase the manufacturing lead time and makes A system which could reduce the iterations and make the presentsa computer-aided system for runner and gating system gener...

A significant amount of past research has studied person identification from point light displays of walking humans, investigating parameters such as viewing angle and the differential contributions of structural and kinematic information. However, little is known about the ability of human observers to generalize identity across different activities. In this study we use a same/different parad...
