Joslyn Zale, Bandana Kar, David Cochran
Football is culturally and economically important in the United States, and football stadiums are part of the country's critical infrastructure, thus receiving government protection against hazard events. In this project, an agent-based evacuation model was implemented to optimize evacuation time from The University of Southern Mississippi's M.M. Roberts Stadium (football) by accounting for evacuees' age, gender, physical fitness, alcohol consumption, and prior experience with hazard events. The findings revealed that (i) the age and gender of an individual impact his/her locomotion speed and (ii) evacuation route choice is influenced by evacuees' perception of its safety and effectiveness...

On a Sunday afternoon almost six months ago, we were deeply moved by the news that our Krešimir is no longer with us. The sad news spread from Sarajevo with the speed only most horrible and saddest news can achieve. And everybody who was reached by these news wondered whether it was possible and whether it was true. Because our professor Kostović left us a day before his 48th birthday. Krešimir Kostović was born on the 16th October 1969 in Zagreb, where he completed primary and secondary education. He enrolled at the University of Zagreb School of Medicine in 1988, and got his medical degree in 1995...

M Barr, T Beaver, D Turczyn, S Cornish
Global Positioning System (GPS) units have recently become popular for monitoring and assessing the workloads of football players. Currently there is a lack of studies examining the validity and reliability of these systems for that purpose, so the aim of the current study was to determine if 15 Hz units (SPI HPU, GPSports, Canberra, Australia) could accurately be used to describe the physical demands of football. A series of cohort studies were carried out with Canadian university football players (n=28). In order to assess the accuracy of the units' ability to measure high velocity sprinting, 12 players performed multiple electronically timed 36...

Wearable inertial measurement systems (IMS) allow for three-dimensional analysis of human movements in a sport-specific setting. This study examined the concurrent validity of a IMS (Xsens MVN system) for measuring lower extremity and pelvis kinematics in comparison to a Vicon motion analysis system (MAS) during kicking. Thirty footballers from Australian football (n = 10), soccer (n = 10), rugby league and rugby union (n = 10) clubs completed 20 kicks across four conditions. Concurrent validity was assessed using a linear mixed-modelling approach, which allowed the partition of between and within-subject variance from the device measurement error...
