The objective of this study is to 1. Investigate in women with cardiac risk factors the acute responses of cardiac autonomic modulation and hemodynamic parameters during and after a dance-based cardiac rehabilitation session and II. Compare these responses with a conventional exercise-based cardiac rehabilitation session. Methods:This will be a crossover-clinical trial that will enroll women with at least one cardiac risk factor. The interventions consist of one dance-based (DB) and one traditional exercise-based (EB) session of cardiac rehabilitation, both composed of initial rest, warm-up, moderate-intensity physical exercise, fast recovery evaluation in orthostatic position, and slow recovery evaluation. The main outcomes are 1. Autonomic modulation, evaluated through heart rate variability linear and non-linear methods, and II. Hemodynamic parameters (heart rate, blood pressure, peripheral oxygen saturation, and respiratory rate). All measures will be evaluated in specific moments during the initial rest, physical exercise, and recovery. Conclusion: The results will allow the safe inclusion of dance-based sessions in cardiac rehabilitation programs opening an important field of research to investigate the long-term effects on physical fitness and cardiac risk factors, as well as adherence and motivation to attend cardiac rehabilitation in the women population.

Background The Parkinson disease (PD) is frequently associated with autonomic dysfunctions. However, data regarding the influence of PD on the autonomic responses to postural changes is limited. Objective To analyze and compare the autonomic responses, evaluated through linear and non-linear methods of heart rate variability, and cardiorespiratory parameters in two groups: Parkinson disease (PDG) and control (CG), at rest and during the active tilt test. Methods A total of 48 participants were analyzed (PDG: n = 25;73.40 ± 7.01 years / CG: n = 23;70.17 ± 8.20 years). The autonomic modulation and cardiorespiratory parameters were evaluated at rest and during the active tilt test. To assess the autonomic modulation the linear indices, at the time (rMSSD, SDNN) and frequency (LF, HF, LF/HF) domains, and the non-linear indices, obtained through the Poincaré plot (SD1, SD2, SD1/SD2), were calculated. The cardiorespiratory parameters evaluated were heart rate (HR), systolic (SBP), and diastolic blood pressure (DBP), peripheral oxygen saturation (SpO2), and respiratory rate. Results At rest, the PDG presented significantly lower values of rMSSD, SDNN, LF, HF, SD1, SD2, and DBP, and higher values of SpO2. During test, in the PD group, modifications were observed in HR, and SBP, besides a reduced parasympathetic response, and an increased global modulation. The qualitative analysis of the Poincaré plot showed that the PDG has a lower dispersion of the RR intervals during rest and the active tilt test. Conclusion Individuals with PD present reduced global variability and parasympathetic modulation at rest, and reduced parasympathetic response and damage in HR regulation when performing the active tilt test, compared with controls.

RESUMOO objetivo foi Descrever as atividades desenvolvidas e caracterizar os participantes do Projeto de Reabilitação Cardiovascular no Ritmo do Samba. Estudo descritivo transversal, realizado com 13 mulheres que participam de um grupo de reabilitação por meio do samba. Dados pessoais, medicamentos, fatores de risco (FR) e mensuração de frequência cardíaca (FC), pressão arterial (PA) e medidas antropométricas foram feitas para caracterização. A PA sistólica e diastólica foram de 121,53±20,75 mmHg e 80,76±12,55 mmHg, respectivamente. A FC de repouso de 75,61±9,72 bpm, circunferência de cintura de 96,42±9,34 cm, circunferência de quadril de 109,42±8,15 cm e a relação entre eles de 0,87±0,05 cm. Histórico familiar (N = 10), sedentarismo (N = 8), obesidade (N = 7) e estresse (N = 7) foram os FR mais prevalentes. Conclui-se que a população participante do projeto é exclusivamente feminina, com idade acima de 50 anos e PA dentro da normalidade. Ainda, os principais FR foram o histórico familiar, sedentarismo, obesidade e estresse. Palavras-chave: Reabilitação cardíaca; Fatores de Risco; Dança. CARDIOVASCULAR REHABILITATION PROJECT IN THE SAMBA RHYTHM OF THE PUBLIC UNIVERSITY OF SÃO PAULO STATE ABSTRACTThe objective was to describe the activities developed and characterize the participants of the Cardiovascular Rehabilitation Project in the Samba Rhythm. A descriptive cross-sectional study was carried out with 13 women participating in a rehabilitation group through samba. Personal data, medications, risk factors (RF) and heart rate (HR) measurements, blood pressure (BP) and anthropometric measurements were made for characterization. The systolic and diastolic BP were 121.53 ± 20.75 mmHg and 80.76 ± 12.55 mmHg, respectively. The resting HR of 75.61 ± 9.72 bpm, waist circumference of 96.42 ± 9.34 cm, hip circumference of 109.42 ± 8.15 cm and the relation between them of 0.87 ± 0 , 05 cm. Family history (N = 10), sedentary lifestyle (N = 8), obesity (N = 7) and stress (N = 7) were the most prevalent RF. It has concluded that the majority of the project's participants is exclusively female, with an age over 50 years old and BP within normality. Also, the main RF were the family history, sedentary lifestyle, obesity and stress.
