Key result
Moderate volume Zone 2 training linked to better autonomic recovery versus higher volume Zone 3 regimens.
Why the study?

How do weekly training loads and intensity zones affect heart rate variability and perceived exertion in elite racewalking athletes?
Monitoring heart rate variability and perceived exertion can help individualize training loads and prevent overreaching in elite athletes.
The aim of this study is to identify the interactions between weekly training loads, intensity zones, the Rating of Perceived Exertion (RPE), and Heart Rate Variability (HRV). To this end, a longitudinal monitoring method was applied to six elite racewalking athletes, selected for their high performance level. Data collection involved daily HRV measurements (including RMSSD, HF/LF Ratio, and their logarithmic transformations) taken in both supine and standing positions, along with RPE assessed after each training session. The data were analyzed using both linear and nonlinear statistical models. The results indicate that moderate training volumes (approximately 140 km/week) and a predominance of Zone_2 intensity favor enhanced autonomic recovery, while higher volumes and Zone_3 intensity are associated with increased physiological stress. Based on these findings, the study recommends regulating training loads and using HRV and RPE together as monitoring tools to individualize training and prevent overreaching.

BELAID et al. (2026) conducted an observational in Elite racewalking athletes (n=6). Moderate training volumes and Zone 2 intensity vs. Higher volumes and Zone 3 intensity was evaluated on Heart Rate Variability (HRV) and Rating of Perceived Exertion (RPE). Moderate training volumes (~140 km/week) and Zone 2 intensity favored enhanced autonomic recovery, whereas higher volumes and Zone 3 intensity were associated with increased physiological stress.
