Abstract/OtherAbstract:
The aim of this paper is to compare two portable devices (heart rate monitor and electromagnetic coils system), able to evaluate two different physiological parameters (heart rate (HR) and ventilation (VE)) with the objective of estimating energy expenditure (EE). We set out to prove that VE is a more pertinent setting than HR to estimate EE during light to moderate activities (sitting and standing at rest and walking at 4, 5 and 6 km.h-1). Eleven healthy males were recruited to take part in this study (27.6 ± 5.4 years; 73.7 ± 9.7 kg). 1. We determined the relationships between HR and EE and between and EE during light to moderate activities. 2. We compared EE measured by indirect calorimetry (EE REF) with EE estimated by heart rate monitor (EE HR) and EE estimated by electromagnetic coils (EE MAG) in upright sitting and standing positions and during walking exercises. We compared EE REF with EE HR and EE MAG. The results showed no significant difference between the values of EE REF and EE MAG. However, the results showed several significant differences between the values of EE REF and EE HR (standing position at rest, walking at 5 and 6 km/h-1). These results showed that the electromagnetic coils system seems to be more accurate in comparison with the heart rate monitor, to estimate EE at rest and during exercise. Taking into consideration these results, it would be interesting to associate the parameters VE and HR to estimate EE. Furthermore, a new version of the electromagnetic coils device was recently developed and provides the possibility to perform measurement under daily life conditions.
