AB [EN] Background: The association between heart rate variability (HRV), training load (TL),and performance is poorly understood. Methods: A middle-aged recreational female runner wasmonitored during a competitive 20-wk macrocycle divided into first (M1) and second mesocycle(M2) in which best performances over 10 km and 21 km were recorded. Volume (km), session ratingof perceived exertion (sRPE), TL, and monotony (mean TL/SD TL) were the workload parametersrecorded. The root mean square of the successive differences in R-R intervals (RMSSD), its coefficientof variation (RMSSDcv), and the RMSSD:RR ratio were the HRV parameters monitored. Results:During M2, RMSSD (p = 0.006) and RMSSD:RR (p = 0.002) were significantly increased, while RRwas significantly reduced (p = 0.017). Significant correlations were identified between monotonyand volume (r = 0.552; p = 0.012), RR (r = 0.447; p = 0.048), and RMSSD:RR (r = −0.458; p = 0.042).A sudden reduction in RMSSD (from 40.31 to 24.34 ms) was observed the day before the firstsymptoms of an influenza. Conclusions: The current results confirm the practicality of concurrentHRV and sRPE monitoring in recreational runners, with the RMSSD:RR ratio indicative of specificadaptations. Excessive training volume may be associated to both elevated monotony and reducedRMSSD:RR. Identification of mesocycle patterns is recommended for better individualization of theperiodization used
