简要总结
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.

研究组 & 干预措施
Control group
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
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.
干预措施: LICE (Other)
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.
干预措施: MICE (Other)
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.
干预措施: HIIE (Other)
Aquatic exercise training
The participants will be submitted to a 12-weeks of aquatic exercise program, twice a week, for 1 hour each day.
干预措施: Aquatic exercise training (Other)
