Reconciling Heart Rate and Power Data Discrepancies: Is Heart Rate the New Limiting Factor in High-Intensity Interval Training or Are We Just Measuring it Wrong?
Is it possible that the traditional consensus on power output being the primary limiter during high-intensity interval training (HIIT) is flawed, and conversely, heart rate is actually the key factor in determining performance - particularly in those with exceptionally high VO2 max values? Or is the discrepancy often observed between heart rate and power data simply the result of poor monitoring techniques or incomplete understanding of each metrics nuances? Should we be re-evaluating the relationship between heart rate and power output in performance analysis, and what would it mean for training prescription if, in fact, heart rate was the primary driver of HIIT performance?
