“…Heart rate at exhaustion was, on average, 95.12% of the predicted maximum (220 -age), a finding similar to that of a sample of 100 elderly Brazilians who underwent symptom-limited exercise stress test in a study carried out by Vacanti et al 17 , in which HRmax was 95.7 of the agepredicted maximum. Wajngarten et al 24 assessed elderly subjects by cardiopulmonary exercise testing (CPET) using a bicycle ergometer and reported that measured HRmax was, on average, 95% of the age-predicted maximum.…”

SummaryObjective: This study sought to compare maximum heart rate (HRmax) values measured during a graded exercise test (GXT) with those calculated from prediction equations in Brazilian elderly women.Methods: A treadmill maximal graded exercise test in accordance with the modified Bruce protocol was used to obtain reference values for maximum heart rate (HRmax) in 93 elderly women (mean age 67.1 ± 5.16). Measured values were compared with those estimated from the "220 -age" and Tanaka et al formulas using repeated-measures ANOVA. Correlation and agreement between measured and estimated values were tested. Also evaluated was the correlation between measured HRmax and volunteers' age.Results: Results were as follows: 1) mean HRmax reached during GXT was 145.5 ± 12,5 beats per minute (bpm); 2) both the "220 -age" and Tanaka et al (2001) equations significantly overestimated (p < 0.001) HRmax by a mean difference of 7.4 and 15.5 bpm, respectively. 3) age was significantly (p < 0,001) and inversely related to measured HRmax.Conclusion: Based on these results, it can be concluded that both prediction equations significantly overestimated HRmax measured during maximal GXT in Brazilian elderly women, a finding that may have important implications when prescribing exercise intensity for this population. In addition, HRmax was inversely related to the volunteers' age, suggesting that the chronotropic reserve continues to decline after age 60.

“…The "220 -age" equation is generally erroneously linked to Karvonen 6 ; however, its original publication is not exactly known. Nonetheless, this is probably the most used strategy for HRmax prediction, including in studies involving subjects of both genders [15][16][17][18] .…”

“…Treadmill stress test -The Bruce treadmill test protocol was used, preceded by a 1 minute warm-up at a speed of 1.0 mph, with no slope, and adapted for a tilt treadmill with gradual and moderate increases of speed and slope 7 . The patients were continually monitored with a 12 lead ECG that was also equipped with a CM5 bipolar lead using the software Ergo PC 13 for Windows.…”

“…Regarding the applicability of the ergometric test in elderly, Vacanti et al 17 they verifi ed that, in spite of the limitations of the test in very elderly populations, it showed safe and effective. However, even the ergometric being safe and effective for the oldest part of the population, this instrument also demands a minimum of technical and human resources that makes unfeasible the prediction of VO 2máx in several places, such as consultation and clinics.…”

Objectives: To correlate the maximal oxygen intake (VO 2max ) in elderely esteem for the effort Test with that one esteem by a model without exercise, and to observe the agreement level between these two methods of evaluation. Materials and Methods: The sample was composed for 150 senior, both sex, with average of age of 67.1 ± 5.11 years. They were included in the sample the volunteers directed for accomplishment of the test of effort by Bruce's protocol and they were excluded those that didn't accomplish the test of effort in consequence of contraindications for such, as well as the individuals with cognitive. The VO 2max then was predicted, without exercise through the application of a questionnaire that if based routinely on the collected clinical data, being these: age, weight, index of corporal mass, cardiac frequency of rest and auto-told physical activity. Later they had carried through the test of effort with the responsible doctor. The correlation was carried through the test spearman rank correlation (α=0.05) and the level of agreement through the test of Kappa. Results: One met a correlation (r=0.77) and a weak general agreement high (Kappa=0.292). Conclusions: Concludes that it had correlation it between the two instruments of prediction of VO 2max and had weak general agreement between them.
