Effectiveness of Aquatic Exercises for Improving Mental and Physical Health in Adults.

Effectiveness of Aquatic Exercises for Improving Mental and Physical Health in Adults: Randomized Clinical Trial

Objective: To compare the effectiveness between aquatic exercises (water aerobics versus Watsu) versus control groups, for improving the outcomes of depression, anxiety, stress, sleep quality, functionality, cognition and quality of life in patients with depression.

Introduction: Considered as the "21st century disease", depression is a silent disease that stands out for its high prevalence and high morbidity, leading to serious consequences. With treatments made in aquatic environment, among them the Water aerobics and Watsu. Objective: To compare the effectiveness between aquatic exercises versus Watsu and versus control group, for improving the outcomes of depression, anxiety, stress, sleep quality, functionality, cognition and quality of life in patients with depression. Methods: This study will be a randomized clinical trial, which will last for two months with a follow-up of one month. All participants will be assessed using specific questionnaires for each outcome and an Improvement Perception Scale (MS). Seventy eight (78) patients with a medical diagnosis of depression, aged 18 to 60 years, who will be allocated to three groups (26 patients for each group) will be treated. GROUP 1: Aquatic exercises (aerobic and resistance), collective session, twice a week lasting 50 min; GROUP 2: Watsu (water shiatsu), individual session, twice a week lasting 50 min; Group 3: control, people with depression. Statistical analysis: Normality distribution will be by Shapiro-Wilk test. For comparisons of the means between and within the outcome groups will be used through Generalized Estimation Equations, with its own syntax, linear distribution and, when necessary, multiple comparisons will be performed using the Bonferroni test to identify differences. Will be calculated for comparisons between the final and initial moments and initial follow-up in each group, statistics such as: mean difference (95% CI), standard deviation of the difference, effect size (Cohen's d). The statistical significance adopted was 5% and the analyzes were performed using the statistical programs SPSS 22.0 and R 3.2.4. The intention-to-treat analysis will be performed.
