Evaluación de la resistencia cardiovascular mediante la frecuencia cardiaca y el consumo de oxígeno en adultos mayores.

Abstract

The Karvonen method establish the maximum cardiac frequency of the subject and help us to obtain the VO2 max, that let us moderate the intensity of the exercise to do an appropriate cardiac rehabilitation, the given proposal pretend to improve the life quality of the elderly and minimize the factors of cardiovascular risks that owns. The present investigative work was done with 90 elderly men and women with high factor of risk. The investigation was a no experimental type, of a cross section with a quantity focus and an explanatory scope. Cardiovascular resistance is defined as the ability to tolerate exertion and the ability to carry out prolonged intense body work; which can be measured with the maximum heart rate of the individual and oxygen consumption by regulating the intensity of the exercise. The concurrent research content was developed in 90 older adults, including men and women with a high-risk factor. The inquiry was non-experimental, with cross-sectional intervention under the quantitative approach and an explanatory scope. Heart rate was evaluated using the karvonen method and oxygen consumption was measured indirectly. Giving as a result that in the evaluation of the Heart Rate we have that in men it is 38% normal, 27% good, 29% bad and 15% excellent, we have that in woman it is 24%, 30% good, 14% excellent and 32% bad. In the consumption of VO2 MAX we have that in men it was obtained 80% normal while in 20% it is diminished; On the other hand, in women we have that 30% is normal and 70% is diminished or bad. Finalizing that the consumption of VO2 is more diminished in women than in men and heart rate in the same way concluding that women have a decreased cardiovascular resistance in relation to men.
