The degree of equivalence of the device PowerCal integrated in a commercial device Garmin while measuring performance in cycling
Jan Kresta, Jan Hnízdil
The aim of this work is to describe the degree of equivalence while measuring performance through device PowerCal integrated in commercial device Garmin. The principle of prediction of these data is the use of prediction equations, and monitoring of heart rate. We compared, in the context of burdening test on the ergometer Sanabike, power output in watts mediated by system PowerCal (mediated measurement of data from HR) and ergometer system Sanabike (the golden standard – direct power measurement in watts). direct power measurement in watts). The final measurements and the degree of equivalence show significant heteroscedasticity. PowerCal device exerts a considerable limits redeemable value especially in low and high levels of burdening.
