Figure 2: Interbeat interval across rest, stationary bicycle effort, and recovery periods for a representative participant from Study 2 at preworkshop and 4week followup time points. A leastsquares polynomial of best fit was calculated for each recording. Within each effort to recovery transition window (dotted lines), the local minimum (a) and maximum (b) were determined, between which the inflexion point (c) was used to derive maximal linear pointslope of the curve as a measure of recovery rate. Across participants with available data at both time points (n = 11), mean pointslope increased from preworkshop to 4week followup (P = 0.077)
