Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

• Blood pressure

  The blood pressure will be measured by a Ambulatory Blood Pressure Monitoring (ABPM).

  Entire day (an average of 24 hours).

• Blood pressure

  The blood pressure will be measured by an automatic blood pressure device (OMRON HEM-720).

  Up to 1 hour post-exercise session

Secondary Outcomes (5)

• Self-reported sleep quality

  Approximately 15 minutes

• Depressive symptoms (Mental disorders)

  Approximately 5 minutes

• Self-reported quality of life

  Approximately 15 minutes

• Level of physical activity (BAECKE modified to elderly)

  Approximately 5 minutes

• Functional Capacity

  Approximately 35 minutes

Study Arms (5)

Control group

NO INTERVENTION

The volunteers will be instructed to remain in an orthostatic position immersed in water up to the imaginary line of the xiphoid process for 45 minutes without performing jerky body movements.

LICE

EXPERIMENTAL

The light-intensity continuou exercise (LICE) session comprises a 45-minute of guide walking into the pool at 55-60% of maximum heart rate (HRmax). The HR will be checked every 2 minutes during the whole session.

Other: LICE

MICE

EXPERIMENTAL

The moderate-intensity continuous exercise (MICE) will bem performed divided into 3 phases: warm-up (10 minutes), main part (30 minutes) and cool down (5 minutes). The warm-up and cool down will be performed at 55-60% HRmax. The main part will last 30 minutes and will be performed by 3 sets of 5 exercises lasting 2 minutes each one at 70-75% HRmax. For all phases, HR will be measured every 2 minutes during the whole session.

Other: MICE

HIIE

EXPERIMENTAL

The high-intensity intervaled exercise (HIIE) will bem performed divided into 3 phases: warm-up (10 minutes), main part (15 minutes) and cool down (5 minutes). The warm-up and cool down will be performed at 55-60% HRmax. The main part will last 15 minutes and will be performed by 2 sets of 5 exercises lasting 30 seconds to each exercise combined with 1 minute of active recovery. The exercise moment will be performed at 80-85% HRmax and the 1-minute active recovery at 55-60% HRmax. For both warm-up and cool down, HR will be measured every 2 minutes. For main part, HR will be measured at the end of each 30-seconds from exercise.

Other: HIIE

Aquatic exercise training

EXPERIMENTAL

The participants will be submitted to a 12-weeks of aquatic exercise program, twice a week, for 1 hour each day.

Other: Aquatic exercise training

Interventions

LICE OTHER

No specific exercise will be performed. The participant will walk into the pool accompanied with a researcher for 45 minutes.

LICE

MICE OTHER

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.

HIIE

Aquatic exercise training OTHER

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.
