What is the following quantity supposed to measure (220-age)? Is this formula accurate and based upon solid experimental data? Explain your answer.
What is the following quantity supposed to measure (220-age)?
Is this formula accurate and based upon solid experimental data? Explain your answer.
- The formula 220 - age gives the value of maximum heart rate of any person in bpm (beats per minute).
For example a persons age is 60, so its heart rate max = 220 - 60 = 160 bmp.
- No this formula ISN'T accurate and neither is it based on experimental data. This formula was just derived from OBSERVATIONAL data from approximately 11 references consisting of published research or unpublished scientific compilations.
->This equation is often presented in textbooks without explanation or citation to original research.
-> In addition, the formula and related concepts are included in most certification exams within sports medicine, exercise physiology, and fitness.
->A brief review of alternate HRmax prediction formula reveals that the majority of age -based univariate prediction equations also have large prediction errors (>10 b/min).
->Clearly, more research of HRmax needs to be done using a multivariate model, and equations may need to be developed that are population (fitness, health status, age, exercise mode) specific.
