Adidas miCoach Pacer is a three-axis accelerometer used for monitoring locomotive physical activity in outdoor environment. The aim of this paper is to determine the degree of reliability and validity of Adidas miCoach device in measuring distance of locomotion with changes of direction and without change of direction.
The sample was consisted of 8 students aged 23,3 ± 1,38 years; body height 177,6 ± 4.1 cm, body weight 79,1 ± 6.5 kg. We evaluated continuous locomotion on an athletic track and discontinuous (by shuttle run test) in sports hall. Results: the covered distances, measured by Adidas miCoach device, are significantly different from the criteria (range r = 0,17-0,57). The largest inaccuracies are evident in unorthodox ways of locomotion (running backwards and run sideways). We did not prove that product Adidas miCoach provides valid and reliable information about measuring distances in locomotion movement activities.
