Key result
Self-reported stress-guided training improves 5 km time-trial performance ~13% vs HRV-guided or predefined endurance programs.
Why the study?
The study aimed to determine whether endurance training guided individually by objective HRV or self-reported stress measures improves endurance performance more than predefined training in recreational runners.
Does individually guided endurance training by HRV or self-reported stress improve endurance performance compared to predefined training in male recreational runners?

Self-reported measures of stress (DALDA) may be superior to HRV or predefined training for individualizing endurance training to enhance performance in recreational runners.
Supports DALDA-guided training to boost endurance performance in recreational runners; extends individualized approaches beyond HRV or fixed plans.
The aim of this study was to determine the effect of endurance training individually guided by objective (Heart Rate Variability-HRV) or self-report measure of stress (DALDA-questionnaire) in comparison to predefined endurance training prescription for improving endurance performance in recreational runners. After a 2-week preliminary baseline period to establish resting HRV and self-reported measure of stress, thirty-six male recreational runners were randomly assigned to HRV-guided (GHRV; n = 12), DALDA-guided (GD; n = 12) or predefined training (GT; n = 12) prescription groups. Before and after 5-weeks of endurance training, participants performed a track field peak velocity (Vpeak_TF), time limit (Tlim) at 100% of Vpeak_TF and 5 km time-trial (5 km TT) tests. GD lead to higher improvements in Vpeak_TF (8.4 ± 1.8%; ES = 1.41) and 5 km TT (−12.8 ± 4.2%; ES = −1.97), than GHRV (6.6 ± 1.5% and −8.3 ± 2.8%; ES = −1.20; 1.24) and GT (4.9 ± 1.5% and −6.0 ± 3.3%; ES = −0.82; 0.68), respectively, with no differences for Tlim. Self-report measures of stress may be used to individualize endurance training prescription on a daily basis leading to better performance enhancement, which may be used with HRV for a holistic understanding of daily training-induce adaptations.

Figueiredo et al. (2022) conducted an RCT in recreational runners (n=36). Endurance training individually guided by self-report measure of stress (DALDA) or Heart Rate Variability (HRV) vs. Predefined endurance training prescription was evaluated on Track field peak velocity (Vpeak_TF) and 5 km time-trial (5 km TT) (ES 1.41). Endurance training guided by self-reported stress (DALDA) led to greater improvements in peak velocity (8.4%) and 5 km time-trial (-12.8%) compared to HRV-guided or predefined training.
