Introduction:

The chronic kidney disease (CKD) is an irreversal progressive process which takes to a terminal state, where patients need permanent dialysis or even a transplant. It has been shown that the lung function and ventilatory capacity are compromised in these patients, increasing the alteration with exposure to hemodialysis and sedentarism.

Objective:

To compare the lung function and ventilatory capacity of hemodialysis patients, according to exposure to intradialysis physical training.

Material and Methods:

Study of quantitive type, not experimental, descriptive and transverse. The study population included 12 ambulatory patients between 40 and 80 years old, undergoing hemodialysis with arteriovenous fistula in the dialysis unit of Valdivia's Central Hospital, and who obtained more than 24 points in the Minimental Test. The statistical analysis was performed with the SPSS program (version 11.5 for Windows) and the level of statistical significance through the Wilcoxon and Mann-Whitney test (p<0.05).

Results:

The comparison of the initial and final pimometry in patients with and without physical training did not show a statistically significant difference (p>0.05), however it was observed that the subjects exposed to physical training have higher values in the initial and final maximum inspiratory pressure compared to those who have not been trained.

Conclusion:

Intradialysis physical training causes a positive effect on the respiratory system. The subjects submitted to hemodialysis tend to present under predicted values in both lung function and ventilatory capacity, being mostly affected with aging and time of exposure to hemodialysis.
