Age-predicted maximal heart rate revisited
Open accessAbstract
OBJECTIVES We sought to determine a generalized equation for predicting maximal heart rate (HRmax) in healthy adults. BACKGROUND The age-predicted HRmax equation (i.e., 220 - age) is commonly used as a basis for prescribing exercise programs, as a criterion for achieving maximal exertion and as a clinical guide during diagnostic exercise testing. Despite its importance and widespread use, the validity of the HRmax equation has never been established in a sample that included a sufficient number of older adults. METHODS First, a meta-analytic approach was used to collect group mean HRmax values from 351 studies involving 492 groups and 18,712 subjects. Subsequently, the new equation was cross-validated in a well-controlled, laboratory-based study in which HRmax was measured in 514 healthy subjects. RESULTS In the meta-analysis, HRmax was strongly related to age (r = -0.90), using the equation of 208 - 0.7 x age. The regression equation obtained in the laboratory-based study (209 - 0.7 x age) was virtually identical to that obtained from the meta-analysis. The regression line was not different between men and women, nor was it influenced by wide variations in habitual physical activity levels. CONCLUSIONS 1) A regression equation to predict HRmax is 208 - 0.7 x age in healthy adults. 2) HRmax is predicted, to a large extent, by age alone and is independent of gender and habitual physical activity status. Our findings suggest that the currently used equation underestimates HRmax…

“However, similar to the original reports by Fox and Haskell (7,8), these studies probably or definitely included subjects with cardiovascular disease who smoked and/or were taking cardiac medications.”

Subjects and Methods (p. 1) reports that three volunteers took mild antihypertensive medications and that none had been told she had cardiovascular disease other than elevated blood pressure. This supports the medication concern in part, but the paper does not report that its volunteers smoked or had other known cardiovascular disease. Its introduction (p. 1) also says medication use was unreported in an earlier study, not that those subjects definitely took medication. (LLM, conf=0.85)

The paper relies on this without support.
Older adults demonstrate the highest prevalence of cardiovascular and other chronic diseases.
“The latter limitation is crucial in that older adults demonstrate the highest prevalence of cardiovascular and other chronic diseases.”
The paper relies on this without support.
Older adults are often reluctant or unable to measure HRmax directly because of concerns about the physiologic stress imposed by strenuous exercise.
“Importantly, older adults are a population in which there is often a reluctance or an inability to measure HR max directly, owing to concerns related to the physiologic stress imposed by strenuous exercise.”
The paper relies on this without support.
The 220 − age HRmax prediction equation is used in older adults more than in any other population.
“Thus, ironically, the 220 Ϫ age HR max prediction equation is used in this population more than in any other.”

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The cited source doesn’t support the claim as written.
In the citing paper

Checked by a reasoning model — may be wrong.
Experimental — accuracy not yet measuredThe cited source says what the claim attributes to it.
In the citing paper
“Moreover, the validity of this equation has never been established in a sample that included a sufficient number of older adults; accordingly, it's utility has been challenged [ 32 , 33 ].”

In the citing paper
“The age-associated decline in maximal heart rate is typically reported to be unaltered by exercise training,139-142 but some evidence suggests that the decline in maximal heart rate with age can be attenuated by vigorous exercise.143-145”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
