This is a randomized controlled trial. The present study involves an acute and chronic intervention, which is a water-based exercise (one session: to acute intervention; 12-weeks of aquatic exercise program: to chronic intervention). The sample will be composed by elderly enrolled in university extension program titled "Hidroginastica na Terceira Idade" (Hydrogymnastics in aging). It will be evaluated the effects of water-based exercise on hemodynamics, self-reported sleep quality, depressive symptoms, quality of life, body composition, level of physical activity and functional capacity. The investigators hypothesized that an acute water-based exercise under different intensities promotes hemodynamics changes in elderly. In addition, the investigators hypothesized that 12-weeks of aquatic exercise may lead improvements in self-reported sleep quality, depressive symptoms, quality of life, body composition, level of physical activity and functional capacity in elderly.

No specific exercise will be performed. The participant will walk into the pool accompanied with a researcher for 45 minutes.
The following exercises will be carried out: a) jumping jacks (shoulder abduction and adduction); b) horizontal adduction and abduction of the shoulder; c) stationary running with knee elevation; d) pull and push horizontally with upper limbs; e) pull and push vertically with upper limbs. Note: For exercises 'a' and 'b', the legs alternated in movements in the sagittal plane to provide greater stability to the participant's movement. For exercises 'd' and 'e', the legs simulates a stationary running.

The sessions of the aquatic exercise training will be divided into 3 phases: warm-up (10 minutes), main part (40 minutes) and cool down. In order to increase intensity to aquatic exercise, the training program will carried out as follows: From week 1 to 4 the instructors will use a 128 bpm musics in both warm-up and cool down. In main part, will be used a 130 bmp musics. From week 5 to 8 the instructors will use a 130 bpm musics in both warm-up and cool down. In main part, will be used a 132 bmp musics. From week 9 to 12 the instructors will use a 132 bpm musics in both warm-up and cool down. In main part, will be used a 135 bmp musics.

Blood pressure
The blood pressure will be measured by a Ambulatory Blood Pressure Monitoring (ABPM).
Time frame: Entire day (an average of 24 hours).
Blood pressure
The blood pressure will be measured by an automatic blood pressure device (OMRON HEM-720).
Time frame: Up to 1 hour post-exercise session
Self-reported sleep quality
Pittsburgh Sleep Quality Index
Time frame: Approximately 15 minutes
Depressive symptoms (Mental disorders)
Geriatric depressive symptoms (GDS-15) is a validated questionnaire which will be used in order to evaluate depressive symptoms in elderly.
Time frame: Approximately 5 minutes
Self-reported quality of life
Quality of life will be assessed by the WHOQOL-OLD questionnaire and it consists of 24 items on the likert scale attributed to 6 facets: 1) Sensory functioning, 2) Autonomy, 3) Past, present and future activities, 4) Social participation, 5) Death and dying, and 6) Intimacy. Each facet is composed of 4 items, so for each facet the score can range from 4 to 20. For this evaluation, the higher the score, the higher the quality of life.
Time frame: Approximately 15 minutes
Level of physical activity (BAECKE modified to elderly)
The Habitual Physical Activity Questionnaire originated in 1982 by Baecke and colleagues (BAECKE; BUREMA, FRIJTERS, 1982) and was adapted for the elderly and validated later (VORORRIPS et al., 1991) and recently translated into Portuguese (SIMÕES, 2009). It is applied in the form of an interview, and has as reference the last 12 months being divided into 3 sections (1 - Domestic physical activities, 2 - Sporting activities and 3 - Activities in free time). From the scores attributed to each response provided by the elderly, scores equivalent to each section cited above are established. It is suggested that 3 cutoff points be created for the classification of the elderly regarding the level of physical activity (low, moderate and high) based on terciles.
Time frame: Approximately 5 minutes
