Dissertation/Thesis Abstract

Accuracy and reliability of heart rate monitor system energy expenditure estimates for upper- and lower-body continuous exercise
by Sopo, Emily R., M.S., California State University, Long Beach, 2015, 129; 1596476
Abstract (Summary)

The purpose of this study was to determine the reliability and accuracy of energy expenditure (EE) measurements for both upper- and lower-body steady-state exercise using the MYZONE® and Activio® heart rate monitoring systems. Thirty-seven participants completed one graded exercise test and three submaximal steady-state tests on a cycle ergometer (LBE) or upper body arm ergometer (UBE). MYZONE® and Activio® EE estimates were compared to values derived through indirect calorimetry and evaluated using a one-way, repeated measures ANOVA (p ≤ 0.05).

Results of this research suggest that the MYZONE® and Activio® systems are less reliable than the criterion measure. Both systems significantly overestimated EE for UBE, and only the MYZONE® system significantly overestimated EE for LBE. Greater error is present on an individual basis. Based on these results, it is recommended that caution is exercised when using EE estimates from the MYZONE® and Activio® systems for the purpose of fitness programming.
