“…Recent guidelines of the Brazilian Society of Cardiology 26,27 have emphasized the use of maximum exertion as an instrument of clinical investigation. The routine incorporation of the 4sET before exercise testing 28 -conventional or with measurement of the expired gases -has the potential to increase the clinically relevant information to be obtained with the use of physical exercise in healthy or unhealthy individuals [29][30][31][32] .…”

160Cardiovascular diseases are the major cause of mortality in Brazil, accounting for 32% of all recorded deaths and 10% of all hospital admissions in 2000 1 . The risk of several cardiovascular events increases many times due to autonomic dysfunction, frequently caused by a reduction in parasympathetic activity 2 , which is a strong and independent indicator of a negative prognosis 3 both in individuals with heart failure 4,5 and after infarction 6 , and even in the general population 7 .There are several valid procedures to investigate the autonomic condition of an individual, providing relevant clinical or physiological contributions, or both [8][9][10] , among which the 4-second exercise test (4sET), originally proposed by Araújo et al 11 , stands out. The 4sET is based on eliminating the vagal cardiac tonus in the first seconds of rapid exercise involving large muscle groups. The 4sET is a pharmacologically validated autonomic test, whose finality is the isolated analysis of the vagal modulation of heart rate in the initial transient of dynamic exercise 12 . Since it was reported, 4sET has been applied in the clinical area in some sports medicine and cardiology laboratories, in addition to being used as an instrument of scientific investigation in the research developed by our group 11,13-18 and also by other research centers 19 .Despite the simplicity and low cost of the 4sET, and the easy interpretation of its results, the need for a cycloergometer remains a limitation for the broader use of the test according to the original protocol. Considering that a cycloergometer is not frequently found in specialized laboratories and clinics for exercise testing, it is necessary to analyze the possibility of performing 4sET under more appropriate conditions. This study aimed to test the operational viability of the 4sET performed in the orthostatic position without an ergometer and to validate a 4sET protocol. MethodsThe study comprised 47 adults of both sexes (40±17 years, 169±9 cm, 72±14 kg) with different clinical conditions, who randomly underwent 3 consecutive repetitions of 4sET in the 2 protocols suggested as follows: 1) the CYCLO protocol using a cycloergometer, according to the original 4sET 12 ; and 2) the alternative ORTHO protocol, with 4sET performed in the orthostatic position. The first repetition in each protocol served to acquaint the individuals with the procedures, and the best result of the last 2 repetitions was considered to represent the vagal cardiac index of the individual. All participants signed the written consent before the tests. The protocol and the study design were approved by the institution. 0.84, 0.85, and 0.93, respectively (P<0.001). Original Article Validation of the 4-Second Exercise Test in the Orthostatic Position ConclusionThe 4sET performed in the orthostatic position proved to be a valid option for assessing the vagal cardiac tonus in laboratories lacking a cycloergometer, without jeopardizing clinical interpretation. In addition to simplicity and applicability, the pr...

“…They were submitted to BP checking 2 , application of the QOL questionnaire 5 and measurement of the abdominal circumference (AC) 2 and body mass and stature, which served for the calculation of the body mass index (BMI) 2 . Afterwards, the medication of the subjects from the EG were gradually removed and the individuals remained up to ten days without pharmacological treatment before they initiated the physical exercise program in a procedure similar to the one proposed for medication removal of the brief ergometry protocol 11 . The individuals who remained with pressure values until stage 2 of SH 2 without medication were included in the study.…”

Introduction: In order to correctly treat hypertension, it is plausible to hypothesize that in the face of regular exercise, these patients would not need anti-hypertensive drugs. Objective: To evaluate the effect of treatment exclusive with exercise on blood pressure (BP) and quality of life (QOL) of hypertensive subjects. Methods: Clinical trial of 32 sedentary hypertensive subjects, 55 ± 9 years, who were under pharmacological treatment (PT) randomly allocated to Exercise Group (EG) and Control Group (CG). At EG, 18 subjects (50% women) at least 10 days after the cessation of PT started the exercise program of 10 weeks, 3x/week, 30 minutes of aerobic exercise followed by resistance exercises, while 14 CG (57% women) remained under PT. Systolic (SBP) and diastolic blood pressure (DBP) was evaluated by auscultation at the beginning and end and QOL were evaluated using the MINICHAL questionnaire.

“…The test was interrupted in case the individual requested it for fatigue or presented any of the absolute criteria for the test interruption, according to the guidelines of the American College Cardiology/American Heart Association 2002 20 . All tests were performed at room temperature of 20 ± 2 o C and relative air humidity between 50 and 70% 21 and followed by a cardiologist with ergometry and life advanced support degree.…”

Introduction and objective: The exercise test with ramp protocol is described as the one which best adapts to physical condition of subjects with heart failure (HF). However, velocity and inclination standard increments have not been described yet. This study aimed to describe the results found after application of an exercise test with ramp protocol adjusted for subjects with HF, New York Heart Association (NYHA) class II and III. Methods: 41 subjects with mean age 46.37 ± 8.98 years and ejection fraction of 31.51 ± 9.45% performed the exercise test with expired gas analysis on treadmill with ramp protocol developed from criteria defined in a study by Barbosa and Silva et al. Statistical Analysis: descriptive analysis was performed with frequency distribution and the test time was presented as mean ± standard deviation. Linear regression model was used and NYHA class, age and ejection fraction were included as explanation variables for the test time. A p value of < 0.05 was considered statistically significant. Results: Mean test time was 8.89 ± 3.57 minutes and the R was 1.12 ± 0.11. Sixty-one percent of the sample presented test duration between 6 and 12 minutes -mean ± 1 standard deviation interval -and 73.2% presented duration between 6 and 15 minutes. Conclusion: This study demonstrated that the majority of the subjects with HF concluded the test with ramp protocol adjusted in time considered adequate in the literature.
