From: Noncontact assessment for fatigue based on heart rate variability using IR-UWB radar
Comparison of LF/HF ratios between ECG and radar.The changing pattern of LF/HF ratios during the experiment was not significantly different between measurement methods whereas it significantly increased in T1 and T2 and returned to the level similar to T0 in T3. The line plots indicate the mean values and boxplots indicate the median and interquartile rage. T0 for Rest (pre-exercise); T1 for Fatigue-1 (post-exercise); T2 for Fatigue-2 (post-exercise); T3 for Recovery (post-exercise).
