Contextualization: In view of the repercussions caused by a stroke, has been placed the importance of aerobic training, especially the treadmill training, in improving functional and cardiovascular variables and the quality of life of individuals affected by the disease. However, few studies have compared the effects of different inclination protocols on the improvement of these variables. Objectives: To evaluate the effects of a treadmill training protocol with different inclinations on functional, cardiovascular variables and quality of life of individuals with chronic stroke. Methods: This is a randomized and blinded clinical trial, in which participated 26 individuals of both genders, aged between 20 and 70 years old, and time post-stroke for more than 6 months. Participants were randomized into 3 groups: control group (CG, n = 8), who performed treadmill training without inclination; experimental group 1 (EG1, n = 8), who performed training with a 5% inclined treadmill; and experimental group 2 (EG2, n = 10), who performed training on a 10% inclined treadmill. Interventions consisted of 3 weekly sessions over a period of 6 weeks. Participants were evaluated in 3 moments (pre-training, post-training and followup) regarding outcome measures (gait speed, functional capacity [distance covered], neuromuscular torque, cardiovascular parameters [systemic blood pressure - BP and heart rateFC] and quality of life). In the statistical analysis, the Shapiro-Wilk test was used to verify the normality of the data; in addition, the two-way Analysis of Variance (ANOVA) with repeated measures was used to verify the effect of the interventions considering the temporal measures (pre-training, post-training and follow-up) and the “group” variable as a factor between subjects. Results: ANOVA did not demonstrate any time * group interaction in any of the HR and BP outcomes, as well as for the functional variables and quality of life. However, the mean BP and gait speed variables were different over time: mean BP showed a reduction (F = 3.604; P = 0.036) and the gait speed showed an increase (F = 4.963; P = 0.014). Regarding the functional capacity, the GE2 presented in the post-training, in comparison with the CG and with the GE1, an effect size (mean difference) of 20.6 and 28.2 meters, respectively. Conclusion: In general, training on an inclined treadmill and training without an inclination produced improvement in cardiovascular (mean BP) and functional (gait speed) variables; however, without superiority of one form of training in relation to the other. Functional capacity was shown to be clinically superior at the 10% inclination, despite not being statistically relevant. None of the types of intervention was able to promote changes in other cardiovascular, functional and quality of life variables of the study participants. The results obtained emphasize the need for further studies on the effects of training on a treadmill on cardiovascular and functional variables, and on the quality of life of individuals with chronic stroke.
