imally”. It is possible that an additional instruction could
further increase expansion and deflation when measuring the
maximal range of motion.
Participants: Two study samples comprising of 100 and 30
healthy volunteers were included.
Methods: Chest expansion was measured using a thoracic
excursion test with a circumference tape around the chest in
100 volunteers. In the other study sample chest expansion was
measured by a Respiratory Movement Measuring Instrument.
Both measurements were made at the level of the fourth rib
and the xiphoid process. The two instructions evaluated were:
“breathe in maximally” and “breathe out maximally” which
were compared to “breathe in maximally and make yourself
as big as possible” and “breathe out maximally and make
yourself as small as possible”.
Analysis: To analyse differences between the two instructions
paired t-test was used. To analyze the order of the tests
two sample t-test was used. Significance level was defined as
p < 0.05.
Results: The addition of the instructions to ‘make yourself
as big/small as possible’ resulted in a significantly increased
thoracic excursion measured by tape, compared to the ordinary
instruction for the total group, and also when divided into
male and female groups at both levels (p < 0.001). Measurements
obtained using the Respiratory Movement Measuring
Instrument also showed a significant difference between the
two instructions in favour of the new instructions at the level
of both the fourth rib (p < 0.002) and the xiphoid process
(p < 0.05).
Conclusions: When measuring chest expansion different
instructions give varying results as was seen when measuring
by tape and RMMI. To assess the maximal chest range of
motion, the patient should be instructed not only to ‘breathe
in/out maximally’, but also instructed to ‘make yourself as
big/small as possible’.
Implications: To measure chest expansion or range of motion
in the ribcage, the instruction is important to consider.

Purpose: The aim of the present study was to evaluate the
relationship among clinical treatment, body composition,
health related quality of life and physical capacity in HIV
patients under optimal medication.
Relevance: Acquired Immunodeficiency Syndrome (AIDS)
is considered a chronic disease and treatment with High
Advanced Antiretroviral Therapy (HAART) is used to retard
the imunossupression and to restore the immunologic system
of HIV patients (Human Immunodeficiency Virus). However,
this treatment may also induce collateral effects such
as lipodystrophy, responsible for morphological changes. In
addition, HIV patients frequently report limitations on daily
living activities, reduction in physical capacity and increased
levels of depression. However, the association among these
factors remains to be elucidated.
Participants: This transversal study evaluated 32 patients
(23 males, mean age of 48 years old) with HIV/AIDS under
HAART treatment were enrolled in this study. Were excluded
patients having either hospitalization or AIDS-defining illnesses
until one month before the study inclusion, those with
clinical history of cardiac, hepatic or renal diseases, and pregnant
patients.
Methods: Patients were submitted to tests to determine maximal
muscle strength (1MR test); maximal (cyclergometer
test) and sub-maximal physical (six-minute walking test)
capacities; anthropometric evaluation (waist–hip ratio); and
immunological condition (total viral load and levels of TCD4
and TCD8 cells).
Analysis: All data analysis was performed in the Minitab
15 ® statistical package. Pearson’s correlation test was used
to evaluate the linear correlation among the outcomes.
Results: Average time of HIV’s diagnosis in this population
was 13 years and the average period under HAART
treatments was 11 years. Maximal and submaximal exercise
capacity tests suggest that evaluated patients presented a
sedentary lifestyle (respectively, 130 Watts (W; from 75 W to
220 W) and 1154 meters (from 900 meters to 1554 meters).
Patients also presented preserved muscle strength either in
upper or lower limbs. It was observed a linear relationship
between HAART treatment and the waist–hip ratio (r = 0.4;
p = 0.03). However, there was no relationship between physi-
