Outcome Measures

Primary Outcomes (1)

  • Change from baseline Blood Pressure (Systolic and Diastolic) following 12 weeks of exercise.

    Blood pressure will be assessed in resting (Omron HEM 7200®, Omron Healthcare Inc, Dalian, China) at the day of the sessions and using a 24 hour ambulatory blood pressure monitoring (Cardio-Mapa ®, Cardios System Ltda, Sao Paulo, Brazil), at the baseline and after 12 weeks of exercise.

    12 weeks

Secondary Outcomes (7)

  • Effect of exercise in hemodynamic and autonomic variables assessed by endothelial function, arterial stiffness and heart rate variability

    12 weeks

  • Effect of exercise in functional capacity assessed by handgrip strength test.

    12 weeks

  • Effect of exercise in functional capacity assessed by 5 times sit to stand test.

    12 weeks

  • Effect of exercise in functional capacity assessed by sit and reach test.

    12 weeks

  • Effect of exercise in functional capacity assessed by timed up and go test.

    12 weeks

  • +2 more secondary outcomes

Study Arms (3)

Control without exercise in heated water-based

PLACEBO COMPARATOR

CON session will perform at controlled heated water-base (30 e 32 ºC). Subject will be seated in a chair and submerged at the xiphoid process level for 30 min.

Other: Control Group

High Intensity Interval Exercise in Heated Water

EXPERIMENTAL

High intensity interval exercise will perform at controlled heated water-base (30 e 32 ºC). Subject will be submerged at the xiphoid process level. The session will consist in 4 min walking (warm-up) at 9 level of rate perceived exertion (RPE) scale, followed by 21 min of HIIE, alternating 1 min of jogging/running at 15-17 (hard-very hard) level with 2 min of walking at 9-11 (very light-fairly light) level of RPE.

Other: High Intensity Interval Exercise in Heated Water-Based

Continuous Moderate Exercise in Heated Water

EXPERIMENTAL

Continuous moderate exercise will perform at controlled heated water-base (30 e 32 ºC). Subject will be submerged at the xiphoid process level. The session will consist in 4 min walking (warm-up) at 9 level (light) of RPE, followed by 26 min of MICE, walking at 11-13 (fairly light) level of RPE.

Other: Continuous Moderate Exercise in Heated Water-Based

Interventions

High intensity interval exercise will perform at controlled heated water-base (30 e 32 ºC). Subject will be submerged at the xiphoid process level.

Participants who has interest to participated will provide an anamnesis to investigator. The investigator will analyse the IDP eligibility or not-eligibility criteria. The eligibility participant will received a document with study protocol, statistical analysis plan, informed consent form, clinical study report and analytic code informations. Thus, investigators will perform cardiopulmonary exercise test to confirm that IDP will be able to study protocol.

Shared Documents
STUDY PROTOCOL, SAP, ICF, CSR, ANALYTIC CODE
Time Frame
Initial data will be analysed at the initial sessions (cardiopulmonary exercise and functional capacity tests); at the day of sessions (study 1), after 12 weeks and 3 months of training interruption (study 2).
Access Criteria
Informed Consent Form described and signed. DP will received Informed Consent Form informing the objectives, study deling, interventions, analyses, risks and benefits. Participation in this study will be voluntary and confidential after signing of an informed consent.
