    In: Sports Engineering, 2016, vol. 19, no. 4, p. 283–287

    Elevation gain (EG) is a significant contributor to the total workload in many endurance sports. Hence, the aim of this study was to evaluate the accuracy of elevation recording as assessed by popular sport watches. Eighteen participants walked and ran at different speeds in various weather conditions in two terrain types: on a hilly 2490 m course with a total EG of 90 m and on a flat 1200 m...

    The influence of the gait-related arm swing on elevation gain measured by sport watches

    Ammann, Rahel ; Taube, Wolfgang ; Neuhaus, Matthias ; Wyss, Thomas

    In: Journal of Human Kinetics, 2016, vol. 50, no. 2, p. 53–60

    The elevation gain is an important contributor to the total workload in endurance sports. The purpose of this study was to evaluate the influence of the arm swing on elevation gain in three sport watches (Garmin® Forerunner 910XT, Polar® RS800CX and Suunto® Ambit2) on a flat 400 m outdoor track. Altogether, a total of 120 repetitions of 1,200 m were performed at self-selected speeds...
