NTRODUCTION
The hemodynamic variables and efficiency test in the step may
be influenced by progressive stages of cargo during the climbs
and descents. During the exercise, the musculature active receives a greater blood flow and heart receives more stimulation,
compared with the state of rest. The most common physiological
parameters for assessments about the health of the cardiorespiratory system during physical effort are the blood pressure (BP)
and heart rate (HR). In tests with the use bench ergometer, there
is a large participation of the musculature and joints of the lower
limbs, realizing it is the involvement of different angles capable
of causing changes in these variables during the response effort.
Souza1 in studies with individuals untrained active and trained in
tests of ascent and descent with bench ergometer, found values
of HR effort in the range of 80-85% of HR maximum (FCM),
featuring a sub-maximum test, which, probably, not elevates the
BP at levels that pose damage to the system. It is known that one
of the problems in the implementation of such tests is to estimate
the BP due to the movement of climb and descent.
Research in normotensive women and untrained in tests with
loads continuous and progressive2,3, have found that levels of BP
characterize hypertension reactive in tests of this nature. There is
still that the first stage of step tests, with increments of continuous
nature, shall begin with adequate time for any individual, even if
it is considered low, which means minors in the knee joint angles
involved in the effort. This causes comfort and accommodation
in postural segments during the test.
Tests using bench, despite being the oldest when it relates to ergometry, does not mean they are the least used. The remainder

must be revised, restructured, as everything in science. They are
the new techniques of application and development of instruments
that compatibility with proposals for further evaluation in the field
of tests.
Research giving rise to new types of instruments and protocols were
developed to expand the use of these ergometer1,3,4,5. It is known
that in Brazil, as well as in the United States, these tests are widely
available and used. Therefore, the proposal presented here is a
new reading of tests in the area, specifically from the step where
employ climbs and descents in cycles of four times, demarcated
by metronomic or other form of cadence the rate. These may be
able to quantify the exercises estimating the degree of physical
ability, usually sub-maximum, which carry maximum prediction,
usually through the index of volume of oxygen (VO2).
Regarding the control of hemodynamic variables, where the BP
and HR, bench ergometer in the form of manual verification may
be impossible or impracticable, especially in the protocols of
progressive and continuous load. Meanwhile, frequency meter
and other resources as may be applicable to reduce the errors of
estimate. As for the BP, the tests of bench usually last on average
between three and six minutes, which may represent very little to
increase the levels of pressure. Taking this variable to the end of
the test, up to thirty seconds, can give us parameters of the values
of BP achieved during the test.
The security in the application of these tests is much greater in terms
of time and effort into their characteristic sub-maximum. Studies
show that, in thirty one thousand tests applied is not returned no
157
deaths when the use of climbs and descents of a step or bench by
rate a demarcated1. So the question guiding this work is: is that
the conduct of HR and the BP change in levels when test under
different loads in trial of climb and descent of bench, using the
Protocol of Bench Electronic of Cirilo. Therefore, the objective of
this work is to analyse the behavior of HR and BP in different loads
in the test of climb and descent of bench Cirilo Protocol.

and gender, as shown in table 2. The rate used was 132 taps for
minute, equivalent to 33 past / minute. The test consists of four
minutes, composed of three stages, with two increases in the height
of the bench, as shown in table 3. The same was divided into
four stages for each day, with progressive effort. On 1st day was
the effort of 1min, in 2nd of 2min, at 3rd of 3min and 4th day, 4
min. Estimate to HR and BP before the test, HR in the effort and BP
post-effort (30s until after the test) by the technique of Koroktoff.
Before the effort, took place heating with specific stretching and
stationary march in the rate of metronomic. The angle of bending
the knee ranged from 45º of the 90º, 1st to the 3rd stage.

and the post-effort, in the 1st, 2nd, 3rd and 4th minute (DBPPE1,
DBPPE2, DBPPE3 and DBPPE4), as prepared in table 5.
When we examined the associations between the variables BP
and HR, there was high correlation to DBPE1 and DBPE4 (1min
and 4min of effort). Table 6 shows the values of “r” in the Pearson
correlation and significance of these associations. Friedman’s test
found significant differences for the BP and HR the 1st and 4th
load (1min and 4min of effort) (p = 0.05) and between levels of
the rest of the BP and HR and the effort (p = 0.05), as table 7.
DISCUSSION
The HR reached the end of the test, according to the mean age
of the equation Karvonen of 220-age, did not achieve 85% of
the HR estimated maximum, characterizing it as sub-maximum.
The values found in charge of 4 minutes, were: HRmáx 179.40
+ 6.58 bpm, SBP 132.00 + 13.04 mmHg and DBP 61.00 +
11.40mmHg. Since the SBP of the load 3rd of minutes was higher
(136.00 + 11.40 mmHg) and DBP of the load of 1 minute also

the adjustments made between the 1st and 3rd minutes of test,
causing a relaxation of arteries after this time in exercises submaximum4.
The step test to increase provides more time for implementation
of the effort, when it relates to mechanical efficiency and angulation of the lower limbs for climbs and descents, encouraging,
therefore, better physiological responses, some research1,3,11 found
that women in active the effort applied in different protocols for
step test causes significant differences between the recovery of HR
assessed. These studies explain that the tests of cargo single largest
cause perception of effort, with less possibility of completing the
test of time. But the test of continuous work and multiple loads
and progressive, the rate of 132 taps for minute, decrease the
levels of perceived effort and HR.
Lim et al. 6 in an experiment with normotensive and hypertensive
subject also suggested a protocol of bench ergometer in test of
three minutes. According to the authors of the work, the step
test showed good reproducibility and good correlation with the
cycle-ergometer a load work equivalent (r = 0.930), and can be
used in the relationship between physical activity and measures
hemodynamic.
In a study with women untrained in bench ergometer found values of HR end of 165 bpm for tests of 3 min rate with touches
of 120 by minute12. And in this study, when it upped the intensity
to 144 taps for minute, the HR also increased, indicating that
even trained in women, increasing the intensity is associated with
higher levels of hemodynamic variables in tests characterized as
sub-maximum12. In research, analysing people trained, active
and untrained of both genders found that it is possible to use
the bench as ergometer indirect method of prediction of VO2máx
by equation, when considering the appropriate height to height,
age, HR, the corporal mass and height of bench3. It was observed
that the consumption of oxygen appears on a minimum rate of
20 to 25 climbs and descents for minute. Other researchers have
chosen to use the bench ergometer to study with a representative
sample of men and women to estimate parameters of the function aerobics13. It is known that the practicality and feasibility of
using this type of ergometer facilitates the completion of studies
in cross section
The rate of effort arises when the person performing the task
in bench between 40 and 50 cm, a height which produces an
angle of bending the knee articulation of 47-60º (thigh to the
lower leg)13,14. It is emphasized that exceed the angle of 90º of
the bending of the knee moving climb and descent, as well as to
hinder the action biomechanics, exposes the individual to a higher
risk of injury. Studies were based on tuning the height of the bench
to better angulation of the knee in the movement to climb and
descent, indicating that they ergometer must be adjusted to the
160
size of the individual corporal closer14,15,16. The biomechanical
efficiency and work require compensation for the anatomical
differences between the heights of individuals13.
The levels of SBP in this study increased and DBP declined linearly
with time of effort. In search similar pattern was found in individuals of both genders, in ergometry with rolling wake, that the
magnitude of hypotension post-exercise is highly variable, but it
is normal2. In another study with use of ergonometry cycle and
rolling wake, noted the absence of DBP fall of post-exercise and
only stabilization16. In search of verifying reductions BP, met up to
40 mmHg and oscillating decrease in SBP of 0-20 mmHg and
DBP 2.5 to 12 mmHg in ergometer wake of rolling16,17.
In studies examining the response of the BP and double product
(DP) is test the physical sub-maximum in bench ergometer adjustable electronic Cirilo6,7, it was found that the BP response effort in
post-hypertensive, in the routine step test ergometer, allow changes
and reductions in the levels of DBP, control the levels of SBP and
DP, suggesting that this type of dynamic and aerobic exercise is
recommended for people hypertension8,18,19.
In a study of coronary different ergometer, ergonometry cycle
and a rolling wake of inferior limbs was possible to see that they
had lower values for HRmax in both ergometer (p = 0.125), which
probably is due to both the regular use of chronotropic negative
action of medications, but also the presence of cardiovascular
diseases, which tend to undermine the chronotropic response to
exercise20.
There are different protocols and procedures for conducting a test
exercise (TE). However, there is always a real and practical difficulty
in determining when an individual actually reached its maximum.
Probably, for its ease of measurement, the HR has been one of
the clinical variables most often employed to characterize the
acquisition of a maximum effort in conventional TE (no measure
of expired gases) from the comparison with ceilings set by age
when it is then called HR maximum (FCM) 20.
The study conducted here applies for populations of coronary, the
ability sub-maximum recommended in its protocol, and allow a
more peaceful for the implementation assessed. Research in order
to derive equations for predicting the widespread maximum load
for young men and women, under the direct method of ergo
spirometry VO2max and to determine the maximum load (Wmax) in
the ergonometry cycle, 30 men and 30 women (26 ± 5 years),
found that in multiple linear adjustment, the maximum load was
explained by age and corporal mass21. The equations proposals
passed by the cross-validation, using another sample with similar
characteristics of age and VO2max composed of 15 men and 15
women. The authors concluded that the generalized equations
were valid for determining the maximum load in the ergonometry
cycle for men and women.
These surveys corroborate the study conducted here, in that
generalized equations for predicting the VO2max were developed
for the test of bench using the ergo spirometry1, indicating be as
practical and effective as its implementation of programmes aimed
quantification of exercise for degree of proficiency .
However, there are signs that the statistical theory says that at
least 50% of healthy individuals should achieve values equal to
or higher than predicted by the regression equation, making this

criterion rather limited and probably invalid in many of clinical situations everyday20. But the environment of the practice of Physical
Education, specifically test, it is perfectly acceptable, provided that
applied for purposes of verification of physical ability and nonclinical, based on diagnoses of cardiorespiratory disorders. If an
individual is not able to climb a step up to 20cm, overcoming
their own corporal weight, probably is with your motor functions
and organic limited or depressed, demanding an intervention of
a medical professional or a Physical Education.
Scholars say that for a better clinical result, a TE should preferably
be maximum, thus allowing for the greatest amount of relevant
information21. However, the decision to use the test maximum
effort or sub-maximum depends largely on the reasons for carrying
out the test, the type of individual to be tested and availability of
equipment and human resources appropriate.
CONCLUSION
The behavior of the HR and the BP, on different charges in trial
of climb and descent of bench Protocol Cirilo, gradually, with
intervals daily, present themselves in accordance with the different
time of execution of the test. This indicates that there are changes
in hemodynamic variables, and the HR increases linearly as the
time of loading, and the SBP and DBP indicate variability of the
1st to the 4th minute. Tests in different ergometer are applied
exacerbatingly, allowing the researchers and evaluators in general parameters for different variables, mainly hemodynamic and
degrees of physical ability.
This favors the application of new techniques on tools for easy
access, portability, reproducibility and able to quantify the performance of programs for prescribing a more effective, such as
the test bench, specifically the protocol of Cirilo, which is a new
preparation of tests such natural. It is important to emphasize
that equipment for tests in ergometry to be employed in the most
diverse options and special features. However, the procedure must
be controlled and the type of protocol applied, considering the
scope and the final product.
