This runway race-track is used to assess acceleration and velocity of small animals as they run end to end. The runway measures 2.5 meters long and has an adjustable width between 2.5 and 12.5 centimeters. Walls are designed with height extensions to accommodate larger animals that may be able to jump out of the track lane. Photobeam “curtains” are spaced evenly at 10 centimeter intervals (24 gates total); as the subject runs end to end they break these photobeams and time is measured between each gate allowing for calculation of acceleration and velocity. System comes complete with software, cables, and all hardware.
