OBJECTIVE: To evaluate the relationship between cardiorespiratory fitness and quality of life in patients undergoing hemodialysis.METHODS: An analytical cross-sectional study performed with hemodialysis patients, male, aged 22-75 years. Fifty patients were evaluated by the cardiopulmonary exercise test (CPET) and by quality of life questionnaire - Kidney Disease Quality of Life-Short Form (KDQOL-SF). The Bruce protocol was adapted with a total duration of 12 minutes, performed on a treadmill with the gas analyzer coupled with collection of expired gases for analysis every 10 seconds. KDQOL-SF was applied during the intermediate dialysis session of the week. Oxygen pulse and chronotropic incompetence were calculated from the CETP variables. The peak oxygen consumption (VO2peak) values were categorized into tertiles for low, moderate and high cardiorespiratory fitness.  Statistical analysis was performed using the Kruskall-Walllis test (Dunn's post hoc test) and Spearman's coefficient to verify the correlation between the variables.RESULTS: The physical component (p = 0.01), specific domains list of symptoms (p = 0.05), sexual function (p = 0.014), sleep quality (p = 0.04), satisfaction with the team (p = 0.03) and total score KDQOL-SF (p = 0.006) increased with the VO2peak tertiles. There were positive correlations of the oxygen pulse (p = 0.01) and chronotropic incompetence (p = 0.02) with the physical component and the O2 pulse with the total score KDQOL-SF (p = 0.02).CONCLUSIONS: There was a positive and significant relationship between the parameters of cardiorespiratory fitness and the physical, mental, and total scores of patients undergoing hemodialysis. In addition, the overload caused by the disease and sexual function were the aspects that seem to be influenced by the cardiorespiratory fitness for being domains that depend on the physical and mental interaction.
