Validity of the Polar S810 heart rate monitor to measure R-R intervals at rest
Article Abstract:
A study compares R-R intervals and the subsequent analysis of heart rate variability (HRV) obtained from the Polar S810 heart rate monitor (HRM) (Polar Electro Oy) with an electrocardiogram (ECG) during an orthostatic test. Narrow limits of agreement (LoA), good correlations, and small effect sizes support the validity of the Polar S810 HRM to measure R-R intervals and make the subsequent HRV analysis in supine position.

A novel energy expenditure prediction equation for intermittent physical activity
Article Abstract:
A study is conducted to characterize the relative contribution of the current Heart Rate (HR) and HR in the previous minute to predict Energy Expenditure (EE) and to model these and other determinants to predict EE during intermittent activity. The result suggest that it is possible to improve the accuracy of predicting EE from HR, by incorporating both VO(sub 2max) and the previous minute's HR in the prediction model.

Individual calibration for estimating free-living walking speed using the MTI monitor
Article Abstract:
A study aims to devise a cost-effective and simple individual calibration method to enhance MTI accelerometer estimation of free-living level walking speed. Results show MTI accuracy in predicting walking speed without individual calibration might be sufficient for population-based studies but not for intervention trials.
