What does this research mean for the field?

The application of the heart rate deflection point (Conconi method) for determining anaerobic threshold is limited because a regular deflection is absent in approximately 14% of healthy young subjects. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Discussion

Implication

Caution advised using HR deflection for anaerobic threshold; leaves open validity beyond young men.

Structured PICO

Population

227 healthy young male subjects, mean age 23 +/- 4 years

Intervention

Incremental cycle ergometer exercise test

Outcome

Degree and direction of the deflection of the heart rate performance curve (HRPC) and the relationship of the heart rate threshold (HRT) to the lactate turn pointsurrogate

The noninvasive determination of anaerobic threshold using heart rate deflection has limited reliability, as approximately 14% of healthy young men show no or inverted deflection.

Limitations

A heart rate deflection cannot be found even in young subjects in some cases, limiting its application in training regulation
