- Effects of a strength exercise program during hemodialysisPublication . Novo, André; Domingues, Ânia; Preto, Leonel; Sousa, Tânia; Mendes, Eugénia; Baptista, Gorete; Vaz, Josiana A.Introduction and Aims: The present study aims to investigate the effects of an intradialytic program of strength exercises in patients with Chronic Kidney Disease. Individuals who undergo hemodialysis are faced with multiple catabolic processes, including protein and energy level, characterized by loss of muscle mass and decreased visceral proteins. Its pathophysiology becomes so complex, multifactorial and few explanations are encountered. However, it is clear that irregularities in muscle function, exercise performance and physical activity initiated in the early stages of CKD will progressively worsening. Methods: Of the 45 participants, 29 were randomly chosen to join the training group (TG) and 16 control group (CG). The TG conducted a program of strength training during hemodialysis sessions for 8 weeks, 3 times per week, while the CG remained with the usual routine. At the beginning of the program was conducted an assessment period: the Sit-to-Stand Test, the Up-and-Go Test, the Hand Grip Test, the Pinch Gauge© and anthropometric and laboratory tests, culminating in the application of SF-36 version 2. We repeated this evaluation procedure after completion of training protocol. Results: Taking into account the results obtained, the TG significantly increased the number of repetitions of the Sit-to-Stand Test (12,22±5,37 initials; 15,4±3,27 final), and improved runtime Up-and-Go Test (16,74±17,38s initials; 11,33±6,26s end). Regarding the right handgrip, this group improved significantly (18,79±11,32Kg/f initials; 21,92±11,73Kg/f end), not even checking the left side (18,5±11,60Kg/f initials; 18,46±11,63Kg/f final). As for digital right grip strength (5,68±2,14Kg/f initial; 6,04±2,88Kg/f end) and left (5,21±2,53Kg/f initial; 4,88±2,31Kg/f end) there is the same situation as in handgrip strength. After completion of training program, in TG the physical component of the SF-36 (version 2) improved significantly (34,178±10,83 initials; final 41,52±8,14), and the same happened with the mental component (51,43±7,33 initial; 52,74±8,47 final). Conclusions: It's visible an increase in the number of repetitions of the Sit-to-Stand Test in GT, declaring statistically significant changes. Through these results, it can be said that the program was beneficial, improving the ability of participants to perform a higher number of repetitions in comparison with the results obtained by many authors; It's clear that the GT had a reduction in the time of execution of the up and go test, with significant statistical differences. These values indicate an improvement in the physical condition of the patients. These results suggest that a program of strength training intradialytic improves functional capacity and quality of life in this debilitated population.
- Effects of an aerobic training in patients on hemodialysis programPublication . Novo, André; Sousa, Tânia; Anes, Eugénia; Domingues, Ânia; Mendes, Eugénia; Baptista, Gorete; Viana, JoãoIntroduction and Aims: The Chronic Kidney Disease and the hemodialysis treatment has significant potential in changing negatively the lifestyle of these patients, leading them to a reliance on health care and rehabilitation and, eventually, loss of social roles. Because of the changes mentioned, it's essential the implementation of strategies and programs for exercise training, designed to minimize many of the complications of this syndrome and consequently contribute to an improved quality of life. This research aims to evaluate the effects of aerobic training in hemodialysis patients with chronic renal disease. Methods: The study population was composed of 100 patients with Chronic Kidney Disease on regular hemodialysis program in the NorDial hemodialysis Unit, being offered to everyone the same opportunity to participate in the program training. Among those who expressed interest and willingness to participate, after application of the exclusion criteria and taking into account the patients choices, the result was a sample of 43 patients to integrate the Group Training (GT) and 16 patients to establish the Control Group (GC). The aerobic exercise program was implemented in early May of 2012 for 8 consecutive weeks, with a frequency of 3 sessions per week during the dialysis treatment. Before and after the intervention were executed the respective functional and physical assessments and the SF36-v2 questionnaire. Results: The training group is characterized by a mean age of 71.93±11.76 years and in hemodialysis 4.29±3.22 years, after the intervention had significant changes in hemoglobin levels of 11.02±0.88g/dL to 11.3±0.698g/dL and hematocrit of 32.55±2.62% to 33.59±1.9%. In the sit to stand test were observed changes in the number of repetitions of 13.24±4.96 to 18.08±6.23 and in the up and go the time to complete the test went from 15.03±10.90s to 9.67±5.74s. In the quality of life, the change was from 49.93±9.953 to 53.22±7.545 in the component related to mental health. Conclusions: The intradialytic aerobic training implemented had a beneficial effect on aerobic capacity/functional of these patients, as well on the perception of their quality of life, specifically in the component related to mental health. Further investigations are needed to determine the effects of this type of training on blood pressure, glucose and EPO dose administered.
