Strength and function gains in the elderly from isometric training with and without visual response

INTRODUCTION:

The remediation of physiological changes affecting the elderly is a problem frequently faced in public health. The urgency of this work is to minimize this remediation and the changes that it induces at the musculoskeletal level, via work done with physical conditioning, seeking to increase the quality of life of this population.

OBJECTIVE:

To evaluate the effect of physical training under two therapeutic commands, with and without visual feedback per pressure unit, as well as possible benefits from increased muscle torque, inherent to the functionality mentioned in the SF-36 questionnaire, thus evaluating the influence of physical training.

METHODS:

The evaluation was conducted using an SF-36 quality of life questionnaire and the sit-to-stand exercise, in addition to measurement of strength by means of the modified sphygmomanometer (MS). The subjects underwent two weekly exercise sessions for a month, with a training protocol that consisted of three sets of 10 isometric repetitions on the flexion-extension chair. Data were statistically analyzed by ANOVA and standard deviation (p<0.05), and Pearson's correlation (p<0.05).

RESULTS:

We observed an improvement in the general conditions of the elderly, with a statistically significant increase in general health, reduced limitation caused by physical problems, reduced pain and increased functional capacity, as well as an increase in the strength of flexion and extension, which had a positive impact on functional testing.

CONCLUSION:

There was highly valid correlation between the strength gained in flexion in the sit-to-stand exercise, which, although lower than the gain in strength in extension, enabled the establishment of a correlation with functional gain, regardless of the visual feedback.
