Article Snippet: How the data were acquired , For seating, a chair with a 90° backrest was utilized. The height of the chairs could be adjusted according to the individuals' height. SKINTACT brand surface-type electrodes were employed. The simulation exertion device used was the BNC-2090 model from National Instruments, and the EMG signal recording device was the PowerLab26T model from Adinstruments..

Figure Lengend Snippet: Correlation between RR intervals obtained simultaneously during a 5-min period by electrocardiogram (ECG) and by mobile phone application (APP). The data are shown as averages of each interval [number of XY pairs=404]. Pearson's correlation was performed with 95% confidence interval (0.99 to 0.99).

Figure Lengend Snippet: Correlation between the frequency domain variables [low and high frequency (LF and HF)] separately calculated by each software [application (APP) and electrocardiogram (ECG)]. Data are reported as means of each registry [n=56]. Pearson's correlation was performed and the 95% confidence intervals were LF=(0.78 to 0.91) and HF=(0.76 to 0.91). nu: normalized units.
