Correlation between the maximal oxygen intake in elderly by indirect assessment with and without physical exercise

Abstract

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.
