VALIDITY, SENSITIVITY AND REPRODUCIBILITY OF STAGES AND GARMIN VECTOR POWER METERS WHEN COMPARED WITH SRM DEVICE

Abstract

The measurement of power output (PO) during cycling has led some manufacturers to develop mobile power meters. However, such devices have to provide a valid, sensitive and reproducible PO. This study aimed to determine the validity, sensitivity and reproducibility of the Stages and Garmin Vector during both laboratory and field cycling tests. The results demonstrate that the Stages and the Garmin Vector systems appear to be reproducible. However, the validity and the sensitivity of the two systems must be treated with some caution.
