Key result
The MHR prediction equation 208 - 0.7 × age was the most accurate in overweight and obese adults, whereas 200 - 0.48 × age significantly overestimated actual MHR (178 vs 175 bpm, p=0.005).
Why the study?
Do MHR prediction equations accurately predict actual maximal heart rate in sedentary overweight or obese adults?

Do MHR prediction equations accurately predict actual maximal heart rate in sedentary overweight or obese adults?
The 208 - 0.7 × age equation provides the most accurate prediction of maximal heart rate for exercise prescription in sedentary overweight and obese adults.
Franckowiak et al. (2010) conducted a cross-sectional in Overweight or obese (n=132). Maximal heart rate prediction equations vs. Actual maximal heart rate was evaluated on Accuracy of maximal heart rate prediction equations. The MHR prediction equation 208 - 0.7 × age was the most accurate in overweight and obese adults, whereas 200 - 0.48 × age significantly overestimated actual MHR (178 vs 175 bpm, p=0.005).
