Key result
High-performance elite female judo athletes had a significantly higher resting LF/HF ratio (3.43 vs 0.83) and mean heart rate than low-performance athletes, indicating dominant sympathetic activity.
Why the study?
The study was conducted to examine differences in autonomic nervous functions according to performance in elite female judo athletes by measuring heart rate variability.
Does resting heart rate variability differ between high-performance and low-performance elite female judo athletes?
Cross-Sectional (n=16)
No
Does resting heart rate variability differ between high-performance and low-performance elite female judo athletes?
High-performing elite female judo athletes exhibit higher resting heart rates and LF/HF ratios, suggesting dominant sympathetic nervous activity potentially related to overtraining or competitive stress.
May signal overtraining risk in elite female judo athletes; hypothesis-generating for HRV monitoring before clinical or training adoption.
PURPOSE: This study was to investigate examined the differences in the autonomic nervous functions of elite female judo athletes according to their performance by measuring the heart rate variability (HRV).

Bae et al. (2020) conducted a cross-sectional in Elite female judo athletes (n=16). High athletic performance (international medals) vs. Low athletic performance (no international medals) was evaluated on Resting LF/HF ratio (p=0.038). High-performance elite female judo athletes had a significantly higher resting LF/HF ratio (3.43 vs 0.83) and mean heart rate than low-performance athletes, indicating dominant sympathetic activity.
