Key result
The 200-0.48xAge equation best predicts maximum heart rate in obese adolescents, within ~2 bpm.
Why the study?
The accuracy of different equations to estimate maximum heart rate during cardiopulmonary exercise testing in obese adolescents was unclear.
Does the equation '200-0.48 x age' accurately estimate maximum heart rate compared to measured values during CPET in obese adolescents?
Comparison
Measured maximum heart rate vs four estimation equations

Mean Difference: 1.9
Absolute Event Rate: 191.9% vs 190%
p-value: p=0.103
The equation '200-0.48 x age' is more accurate than traditional equations for estimating maximum heart rate in obese adolescents during exercise testing.
Heinzmann‐Filho et al. (2018) conducted a cross-sectional in Obesity (n=59). HRmax predictive equations vs. Measured HRmax was evaluated on Maximum heart rate (HRmax) (MD 1.9, p=0.103). The '200-0.48 x age' equation accurately estimated maximum heart rate in obese adolescents (mean difference 1.9 bpm, p=0.103), whereas other common equations significantly overestimated it.
