About

This study evaluates whether the use of moderate physical exercise character in water is beneficial for pregnant women. Half of the participants will carry out moderate physical exercise character in water, following the protocol developed specifically for this purpose and called SWEP (Study Water Exercises Program) method, while the other group will not perform physical exercise during pregnancy.

Concluded the postpartum period, women perform exercises aimed postpartum recovery. The women's group has conducted exercises during pregnancy postpartum recovery made under the guidance of LPF (Low Pressure Fitness) method.

Full description

Preliminary phase:

Current status of the subject.

During this phase will be an updated systematic search research topic. The literature search in databases such as MEDLINE, SCOPUS, CINAHL, WoS (Web Of Science) among others.

Data Collection: The source for the collection of primary data is through a personal interview with the participants and through the primer health of pregnant and/or medical history.

Interview on the first visit:

Collect socioeconomic and health data about participants: age, parity, weight, BMI, smoking habits, drug use, profession/occupation, education level, physical activity pattern prior to pregnancy. Degree of overall health perception. Assess the risks according to the guide of the American College of Obstetricians and Gynecologists. Obtaining informed when agreeing to participate in the study consent. Give information pack about the exercises that the investigators will perform well as controls to be made in each session, and general rules to practice any physical activity.

Execution:

Classes are held in the morning hours preferable between 10 and 11 o'clock in the morning after a caloric intake and adequate hydration.

Every participant should carry your water bottle during each session that will take place, as well as adequate clothing, in which bathing suit, hat, glasses and proper footwear is included to prevent falls.

Before each class dynamics to follow and the signs that will make the exercise should stop, every participant should know how to take her own pulse at the level of the carotid artery may recall, because at different times of the central activity will take frequency heart, as a general rule must be able to hold a conversation without much difficulty while performing the exercise, and during the performance of this should properly hydrated according to the needs of each one in particular.

Warm up: The warm-up exercise will take place in a small vessel, where the water depth is around the thighs.

The session starts with the upper body and decreasing order to heat the lower body.

Central part of the activity. It is be held in the large vessel, exercise intensity will increase in order to keep within the limits for an exercise of moderate, use different devices support to carry it out and exercises of strength, endurance and pelvic elasticity are included.

Assistive devices that will use floating elements that will help us reduce the intensity of exercise providing flotation and will serve as support material to work specific parts. These devices are floating tables expanded polystyrene foam boys pull soft polyethylene and flexible floating bars and playful elements, such as balls, rings, ... spades.

Phase cool down. In this phase the participants will seek to return to calm, will be done in the small vessel having 3-4 ° C more than the large glass. exercises to progressively reducing the intensity and ending with relaxation exercises will be conducted .

The exercises are flexibility the investigators will not keep avoiding positions that strain the joints due to the state of gestation, those areas that have been previously exercised not to exceed the natural movement will stretch.

Once found befallen birth one review and extraction of data on birth process will take place and will take a final interview with the participant to collect data that will be obtained during the postpartum period such as type of feed received by the newborn, and value the existence of postpartum depression with the Edinburgh test.

Concluded the postpartum period. Women begin a program of recovery postpartum 12 weeks, 3 times a week in sessions of one hour. They perform warm-up exercises, a central part of Low Pressure Fitness exercises and end with stretching exercises.

Physical activity

Experimental group

Description:

The women in the EG (Exercise Group) performed moderate physical exercise in water, following the SWEP method (Study of Water-based Exercise during Pregnancy). It consists of performing moderate physical exercise in an aquatic environment from weeks 20 to 37 of gestation. The sessions take place three times weekly, with a duration of 60 minutes each (45 minutes of activity followed by 15 minutes of relaxation). The sessions are composed of three phases: a) warm-up; b) the main phase, divided into aerobic exercise and strength-endurance exercises, designed specifically for pregnant women; c) stretching and relaxation. After the postpartum period, women begin a program based on postpartum recovery exercises Fitness Low Pressure method 12-week, 3 days a week, in sessions of 60 minutes.

Treatment:

Behavioral: Physical activity

No exercise

No Intervention group

Description:

The CG (Control Group) received the standard recommendations during pregnancy, including guidelines from the midwife on the positive effects of physical exercise. These participants received the usual visits from healthcare providers (midwives, obstetricians and family doctor) during pregnancy, as did those in the EG. After the postpartum period, the women in the control group did not perform regulated physical activity.
