“…Among other questionnaires that also evaluate functional capacity, such as the Veterans Specific Activity Questionnaire (VSAQ) 20 , the Specific Activity Questionnaire (SAQ) 18 and the Specific Activity Scale of Goldman (SAS) 21 , the DASI showed better correlation with VO 2 obtained by using the exercise test 18 . The correlation between DASI and VO 2 peak showed good to excellent correlation when applied as an interview (r = 0.81, p < 0.001) and moderate when self-administered (r = 0.58, p < 0.001), being better than the correlation between peak VO 2 and SCCS (r = 0.49, p < 0.01) and SAS (r = 0.30, p < 0.01) in subjects with DCV 4 .…”

BackgroundThe Duke Activity Status Index (DASI) assesses the functional capacity of patients with cardiovascular disease (CVD), but there is no Portuguese version validated for CVD. ObjectivesTo translate and adapt cross-culturally the DASI for the Portuguese-Brazil language, and to verify its psychometric properties in the assessment of functional capacity of patients with CVD. MethodsThe DASI was translated into Portuguese, then checked by back-translation into English and evaluated by an expert committee. The pre-test version was first evaluated in 30 subjects. The psychometric properties and correlation with exercise testing was performed in a second group of 67 subjects. An exploratory factor analyses was performed in all 97 subjects to verify the construct validity of the DASI. ResultsThe intraclass correlation coefficient for test-retest reliability was 0.87 and for the inter-rater reliability was 0.84. Cronbach's α for internal consistency was 0.93. The concurrent validity was verified by significant positive correlations of DASI scores with the VO2max (r = 0.51, p < 0.001). The factor analysis yielded two factors, which explained 54% of the total variance, with factor 1 accounting for 40% of the variance. Application of the DASI required between one and three and a half minutes per patient. ConclusionsThe Brazilian version of the DASI appears to be a valid, reliable, fast and easy to administer tool to assess functional capacity among patients with CVD.

“…In the study #2, subjects had a maximum exercise test conducted on an electronically braked cycle ergometer (Excalibur Sport, Lode, USA) using the ramp protocol [ 32 ]. The power was increased every 60s at an individual rate based on the subjects’ exercise history questionnaire (Veterans Specific Activity Questionnaire) [ 33 ] to induce fatigue within 8 to 12 min. The test was completed when subjects could no longer maintain the required power, despite verbal encouragement.…”

Lymphocyte Redox Imbalance and Reduced Proliferation after a Single Session of High Intensity Interval Exercise

et al. 2016

View full text Add to dashboard Cite

This study investigated whether an acute session of high-intensity interval training (HIIT) is sufficient to alter lymphocyte function and redox status. Sixteen young healthy men underwent a HIIT session on a cycloergometer, consisting of eight bouts of 1 min at 90–100% of peak power, with 75 seconds of active recovery at 30 W between bouts. Venous blood was collected before, immediately after, and 30 minutes after the HIIT session. In response to Staphylococcus aureus superantigen B (SEB) stimulation, lymphocyte proliferation decreased and the IL-2 concentration increased after the HIIT session. However, the HIIT session had no effect on lymphocyte proliferation or IL-2 response to phytohemagglutinin stimulation. The HIIT session also induced lymphocyte redox imbalance, characterized by an increase in the concentration of thiobarbituric acid reactive substances and a decrease in the activity of the antioxidant enzyme catalase. Lymphocyte viability was not affected by the HIIT session. The frequencies of CD25+ and CD69+ T helper and B lymphocytes in response to superantigen stimulation were lower after exercise, suggesting that superantigen-induced lymphocyte activation was reduced by HIIT. However, HIIT also led to a reduction in the frequency of CD4+ and CD19+ cells, so the frequencies of CD25+ and CD69+ cells within the CD4 and CD19 cell populations were not affected by HIIT. These data indicate that the reduced lymphocyte proliferation observed after HIIT is not due to reduced early lymphocyte activation by superantigen. Our findings show that an acute HIIT session promotes lymphocyte redox imbalance and reduces lymphocyte proliferation in response to superantigenic, but not to mitogenic stimulation. This observation cannot be explained by alteration of the early lymphocyte activation response to superantigen. The manner in which lymphocyte function modulation by an acute HIIT session can affect individual immunity and susceptibility to infection is important and requires further investigation.

The stress test consists in a procedure where an individual undergoes programmed physical exercise in order for the physician to assess clinical, hemodynamic, and electrocardiographic responses. 1 The exercise can be performed using a treadmill or a stationary cycle ergometer, and many protocols are available according to the test objective, being adaptable to patient conditions.Even though it was created more than 5 decades ago, the Bruce protocol is still the most widely used in the world's main laboratories. 2 Its increments are performed every 3 minutes, but an increase of around 3 metabolic equivalents of task (MET) at each stage may hinder the adaptation of sedentary individuals and those who have heart diseases and physical limitations, leading to the early interruption of the test.Technological advances allowed the creation of new protocols with smoother speed and incline increments, the so-called ramp tests. 3 The first report of the ramp protocol is from the 1980s using a stationary cycle ergometer and, in the following decade, with a treadmill. 4,5 The main advantage of the ramp protocol, with smoother and more linear increments when

Validade e equivalência da versão em português do Veterans Specific Activity Questionnaire

Abstract: Background: The Veterans Specific Activity Questionnaire (VSAQ) has been used to individualize exercise testing (ET) and to indirectly assess cardiorespiratory fitness (CRF) in epidemiological studies. Nevertheless, there is no validated Portuguese version.
