Experimental protocol.
Fig 1.
Raw EDA signal for a given subject throughout different body positions and exercise stages.
Table 2.
Fmax, EDA measures and % HRmax for different stages.
Fig 2.
Power spectral density of EDA for a given subject during different events and computed Fmax.
Fmax values increase concomitantly with exercise intensity.
Fig 3.
Time-frequency representation of EDA for a given subject.
Vertical lines demarcate the transition between stages. Instantaneous Fmax (white line) is computed for each time point.
Fig 4.
Box plots for estimated Fmax for all exercise stages and subjects.
Time-invariant (top panel) and time-varying (bottom panel) approaches. In each box, the central mark is the median, and the edges of the box are the 25th and 75th percentiles. (*) represents significant difference to stages 1 and 2. (†) represents significant difference to stage 1. (‡) represents significant difference to stages 1 through 4.
