This study aimed to develop new equations
to estimate cardiorespiratory fitness specifically
for older adults and, secondly, to analyze the associations
of cardiorespiratory fitness, both objectively
measured and estimated using new equations, with
cognitive performance. Ninety-two older adults (41
females, 65–75 years) from baseline data of a randomized
controlled trial were analyzed (“ClinicalTrials.
gov” Identifier: NCT03923712). Participants
completed 4 measurement sessions including (i) physiological
and health indicators in a laboratory setting,
(ii) field-based fitness tests, (iii) sociodemographic and physical activity questionnaires, and (iv) a battery
of neuropsychological tests to evaluate cognitive performance.
The main findings were as follows: (i) a set
of new equations with good predictive value for estimated
cardiorespiratory fitness were developed (74–
87%), using different scenarios of complexity and/
or equipment requirements, and (ii) higher estimated
cardiorespiratory fitness, even using its simplest
equation (eCRF = − 1261.99 + 1.97 × 6 min walking
test (m) + 1.12 × bioimpedance basal metabolic rate
(kcal/day) + 5.25 × basal heart rate (bpm)), was associated
with better cognitive performance evaluated
by several neuropsychological tests (i.e., language, cognitive flexibility, fluency, attention, and working memory), similar to using objectively measured cardiorespiratory
fitness. In summary, a new set of estimated
cardiorespiratory fitness equations have been
developed with predictive values ranging from 74 to
87% that could be used based on necessity, availability
of equipment, resources, or measurement context.
Moreover, similar to objectively measured cardiorespiratory
fitness, this measure of estimated cardiorespiratory
fitness was positively associated with performance
on language, fluency, cognitive flexibility,
attention, and working memory, independently of sex,
age, and education level.
