Background
Cardiovascular capacity of chronic kidney disease (CKD) patients tends to decline with the natural progression of the disease. In this sense, resistance training is an important non-pharmacological tool in the control of cardiovascular (CDV) parameters. However, there is no evidence of isometric handgrip training (IHT) protocols in this population. Thus, the aim of this study was to verify the safety of two isometric RT protocols on CDV variables in hemodialysis (HD) patients.
Methods
This was an experimental study, with acute intervention, cross-over design and sample of 8 patients, mean age 56.63 ± 12.66 years, who undergoes HD at a private clinic in the city of Brasília – DF. The participants were randomly assigned to three different moments to analyze the response of the variables heart rate variability (HRV) and blood pressure (BP), being: 1) control; 2) low-intensity; 3) moderate-intensity. Variables were collected at the beginning of session 5, 15, 30, 40, 60 minutes and immediately after the end.
Results
IHT protocols, regardless of intensity, did not show a significant change for both HRV and BP variables during their performances, nor when compared to the control moment. When the moments immediately before and after exercise were analyzed, a significant increase was observed for SBP (120,3±4,6 vs 126,7±4,6, p<0.05) and DP (8634,5±398,5 vs 9419,1±545,3, p<0.05) in the protocol of moderate-intensity, but returning to normal values 10 minutes later.
Conclusion
Therefore, we conclude that the intradialytic IHT seems to be a safe therapeutic tool for the intradialytic control of cardiovascular parameters in this population.
