Key result
The heart rate break point correlated strongly with the anaerobic threshold (r=0.97) with no significant difference in power output (234.5 vs 240.0 W), predicting anaerobic over aerobic threshold.
Why the study?
Does the heart rate break point (BrP) during incremental exercise better predict the anaerobic threshold (AnT) or the aerobic threshold (AeT)?
Population
27 subjects (11 in initial test, 16 in reproducibility test) with different levels of conditioning
Design
Cross-sectional

BrP may align with AnT over AeT in incremental testing; hypothesis-generating and requires prospective validation before guiding training.
Observational (n=27)
Does the heart rate break point (BrP) during incremental exercise better predict the anaerobic threshold (AnT) or the aerobic threshold (AeT)?
Effect estimate: r 0.97
The heart rate break point during incremental exercise coincides with the anaerobic threshold rather than the aerobic threshold, though it may not be reproducible in all subjects.
Ribeiro et al. (1985) reported an observational. Heart rate break point (BrP) vs. Aerobic threshold (AeT) and Anaerobic threshold (AnT) was evaluated on Correlation and mean difference between heart rate break point, anaerobic threshold, and aerobic threshold (r 0.97). The heart rate break point correlated strongly with the anaerobic threshold (r=0.97) with no significant difference in power output (234.5 vs 240.0 W), predicting anaerobic over aerobic threshold.
