• Registration Number: NCT03403478
• Lead Sponsor: Federal University of Paraíba

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.

Arm && Interventions

Group	Intervention	Description
MICE	MICE	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.
LICE	LICE	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.
HIIE	HIIE	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.
Aquatic exercise training	Aquatic exercise training	The participants will be submitted to a 12-weeks of aquatic exercise program, twice a week, for 1 hour each day.

Primary Outcome Measures

Name	Time	Method
Blood pressure	Up to 1 hour post-exercise session	The blood pressure will be measured by an automatic blood pressure device (OMRON HEM-720).

Secondary Outcome Measures

Name	Time	Method
Level of physical activity (BAECKE modified to elderly)	Approximately 5 minutes	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.
Self-reported sleep quality	Approximately 15 minutes	Pittsburgh Sleep Quality Index
Depressive symptoms (Mental disorders)	Approximately 5 minutes	Geriatric depressive symptoms (GDS-15) is a validated questionnaire which will be used in order to evaluate depressive symptoms in elderly.
Self-reported quality of life	Approximately 15 minutes	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.
Functional Capacity	Approximately 35 minutes	AAPHERD test battery
