The aim of this study is to investigate the chronic hemodynamic and autonomic repercussions of the insertion of VRBT in CR. To qualitatively analyze the perception of patients and physiotherapists regarding the use of VRBT, as well as their association with CR, and through a new questionnaire that takes into account patients 'adherence, identifying which are the main barriers that influence patients' absences.
Introduction: Despite the benefits that cardiovascular rehabilitation programs (CR) can promote, there are problems regarding adherence, which can be related to several factors, among them, motivation. Alternative therapies can reflect on motivation and promote increased adherence to CR. In this context, virtual reality-based therapy (VRBT) appears as an option. Additionally, chronic hemodynamic and autonomic repercussions of VRBT in relation to CV still need to be investigated. Objective: To evaluate the chronic hemodynamic and autonomic repercussions of the insertion of VRBT in CR. To qualitatively analyze the perception of patients and physiotherapists regarding the use of TRV, as well as their association with CR, and through a new questionnaire that takes into account patients 'adherence, identifying which are the main barriers that influence patients' absences. Methods: cardiac patients or individuals with factors that regularly participate in CR will participate in this study. Patients will be randomly allocated to CR + VRBT intervention or keeping the normal routine. Interventions will be carried out three times a week for 12 weeks. The primary outcome will be to assess chronic hemodynamic repercussions (blood pressure, heart rate, respiratory rate, oxygen saturation and perceived exertion using the Borg scale) and autonomic (linear and non-linear data). The secondary outcome consists of a qualitative assessment through a focus group with patients and a focus group with therapists, in addition, the new questionnaire developed to identify the influence of barriers on patients' adherence to CR will be applied.

The warm-up was performed using the "Just Dance 2015" game, in a sequence previously defined in a pilot study, aiming to increase HR progressively. A multimedia projector (Epson Power Life, H309A, China) connected to a console (Xbox One KinectTM, Microsoft, Redmond, WA) was used to project the game onto a white wall.The conditioning phase was performed using the "Shape Up" exercise game, in which patients perform exercises following a virtual therapist.

Chronic autonomic response: linear indices
Measured using heart rate variability : SDNN: the standard deviation of normal-to-normal intervals, ms; rMSSD: the root mean square of successive difference between normal intervals,ms; RRtri: triangular index, based on RR intervals,ms; TINN: triangular interpolation of the normal to normal interval between consecutive heart beats, ms; LF: low frequency, nu; HF: high frequency. In general higher values represent a better autonomic response.
Time frame: Change from baseline at 6 and 12 weeks
Chronic autonomic response:no linear indices
Measured using heart rate variability : Detrended Fluctuation Analysis, Recurrence Plot, Multiscalar Entropy, symbolic analysis.In general higher values represent a better autonomic response.
Time frame: Change from baseline at 6 and 12 weeks
Blood pressure
Measured using both systolic blood pressure and diastolic blood pressure
Time frame: Change from baseline at 6 and 12 weeks
Heart rate
Measured using an equipment validated for recording heart rate beat to beat
Time frame: Change from baseline at 6 and 12 weeks
Respiratory rate
Measured using the number of respiratory incursions in one minute
Time frame: Change from baseline at 6 and 12 weeks
Oxygen Saturation
Measured using an oximeter
Time frame: Change from baseline at 6 and 12 weeks
Perceived Exertion
Measured using Borg Scale, this scale varies from 6 to 20
Time frame: Change from baseline at 6 and 12 weeks

Perception of physiotherapists about the barriers and facilitators of the use of Virtual reality
Measured by a focal groups with 5 therapist, that used virtual reality. Focal groups will be conducted by a researcher using a previously developed script, with open questions. The moderator will be a PhD student, with previous experience in physical training and qualitative research. A second researcher will be present at the focal groups to detail notes of the participant's answers.
Time frame: After 12 weeks
Perception of patients about Virtual reality
Measured by a 3 focal groups with 4 to 8 patients each, that performed virtual reality. Focal groups will be conducted by a researcher using a previously developed script, with open questions. The moderator will be a PhD student, with previous experience in physical training and qualitative research. A second researcher will be present at the focal groups to detail notes of the participant's answers.
Time frame: After 12 weeks
Barriers identification in frequenters of Cardiovascular Rehabilitation.
Measured by a new questionnaire of barriers. This new questionnaire has 15 questions, which are divided into domains.
Time frame: After 12 week
