description: INTRODUCTION:<br>
The aging process is inevitable, but it varies from individual to individual the effects caused by it, it is known that active aging slows down the degenerative effects caused by advancing age, thus being dependent on the program of activities practiced over time will contemplate modifications different substances on the motor and cognitive performances compared to the elderly who do not have an active lifestyle. Objective: To analyze the acute effects of different sessions &lt;automatic, dual task, cognitive and moment control&gt; on gait performance and executive function in physically active elderly women. 

METHODS:<br>
This is a randomized controlled trial with a cross-over design, where each subject will undergo two sessions of scientifically-based physical exercises &lt;dual task and automatic session&gt;, a session with cognitive stimulation and a control momentum, as described The dual task session occurred through exercises with stimuli based on motor learning with new movements in the aquatic environment, the automatic session occurred through exercises with standardized movement in the aquatic environment, and the cognitive session occurred through cognitive &lt;audiovisual&gt; stimuli by In the midst of a video demonstrating aquatic physical exercises, the moment of control there was no type of motor and cognitive stimulation, in which the subjects remained lying on a mat. To analyze the effect on gait performance, the gait and gait test was used in different situations and to analyze the executive function, we used the gait tests A and the stroop test. The normality of the data was verified by the Shapiro-Wilk test. The data were expressed in median and 25th and 75th percentiles. Friedman test was applied to compare the absolute change values &lt;? = post - pre&gt; of each dependent variable between the exercise sessions. Wilcoxons test was used in the intra-condition comparison of each dependent variable. The size of the effect was calculated by the following formula: [z / v n]. The level of statistical significance was set at p &lt;0.05. Statistical procedures were performed using SPSS for Win / v.22.0 &lt;Statistical Package for Social Sciences, Chicago, IL, USA&gt;.

RESULTS:<br>
Regarding gait performance and executive function, no statistically significant difference was found between the sessions &lt;dual task, automatic, cognitive and moment control&gt;, but a better motor-motor gait was observed after the automatic session &lt;p = 0.015&gt; and double task &lt;p = 0.001&gt; and motor-cognitive torque only after the dual task session &lt;p = 0.032&gt;. We also observed an improvement in the Stroop test after automatic sessions &lt;p = 0.003&gt; and double task &lt;p &lt;0.001&gt; 0.001&gt; and cognitive &lt;p &lt;0.001&gt;. There was no effect on the control session variable &lt;p&gt; 0.05&gt;. 

CONCLUSION:<br>
The results of the study demonstrated that the dual task protocol presented a potential positive effect on the improvement of motor-cognitive performance and cognitive functions in physically active elderly women, related to the aspect of mobility and cognitive aspect. Thus, the encouragement of the addition of exercises whit other dua-task demand sessions in clinical pratice and regular physical activity practices is suggested as a way to improve functional performance and prevent prossible accidents in active elderly women. <br>
