The acceleration dependent validity and reliability of 10 Hz GPS
R Akenhead, D French, KG Thompson… - Journal of science and …, 2014 - Elsevier
Objectives To examine the validity and inter-unit reliability of 10 Hz GPS for measuring
instantaneous velocity during maximal accelerations. Design Experimental. Methods Two 10
Hz GPS devices secured to a sliding platform mounted on a custom built monorail were
towed whilst sprinting maximally over 10 m. Displacement of GPS devices was measured
using a laser sampling at 2000 Hz, from which velocity and mean acceleration were derived.
Velocity data was pooled into acceleration thresholds according to mean acceleration …
