Official title:
Effects of the Method Pilates Exercises in Muscle Strength Respiratory of Elderly Women: a Clinical Trial
Introduction: Among the systems of the organism, it is believed that the respiratory system is the one which gets older faster due to the greater exposure to environmental pollutants over the years.The Pilates method has emerged as a form of fitness particularly providing general welfare to the individual. Objective: To evaluate the effects of Pilates' exercises on respiratory muscle strength in elderly women. Methods: The investigators have studied 07 women aged 60 and over, with preserved autonomy and cognitive skills. The Pulmonary Function Test (Spirometry) was performed using the Vitalograph® spirometer, model 8600. Respiratory muscle strength was obtained by technical measurements of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP), through an analog Gerar manometer. The experiment lasted eleven (11) weeks. For comparative analysis of the data obtained in the evaluations, the investigators applied the paired t test and a significance level of 5%.
METHODOLOGY This study is a clinical, longitudinal, prospective trial conducted at the
Laboratory of Kinesiology and Cinesioterapia of Physiotherapy, Federal University of
Triangulo Mineiro - UFTM. All participants signed an informed consent. The research started
after approval by the Ethics Committee UFTM Research Protocol (2147-2012).
Subject Initially the invitation was made to all students enrolled in the Open University of
Third Age - UATI / UFTM from August to October 2012.
The selection was based on the following inclusion criteria: (1) age and above 60 years, (2)
non-practicing regular physical activity, (3) availability to attend Pilates classes twice a
week (in addition to the time UATI ) and (4) with preserved cognitive autonomy and exclusion
criteria: history (1) diseases that directly affect the posture (disc herniation and angular
deformities of the spine), (2) cardiovascular, respiratory and neurological diseases that
prevent attainment of Pilates exercises, (3) impaired cognitive capacity limited autonomy or
self-determination, (4) withdrawal of participation during the assessment process, and (5)
two consecutive absences or a total of three absences during the proposed time for the
training set.
Thus, the proposed methodology for this study was applied in seven women with a mean age of
64 ± 6 years.
Review / Procedures The assessment instruments were used: (1) Initial Assessment Sheet, (2)
spirometer and (3) manometer.
The record initial assessment and spirometry were applied for the selection of participants.
Through the initial evaluation form was possible to assess aspects of health status of
participants (associated diseases, blood pressure, respiratory and heart rate, postural
assessment) as well as information on personal history, family history and current
medication .
A pulmonary function test (spirometry) was performed using the Vitalograph ® spirometer
brand model 8600. Equipment was calibrated, and the tests were performed by a single trained
and qualified examiner with instructions and standardized voice commands, as I standards
advocated by Consensus Brazilian on Espirometria.12 Spirometry was performed to rule out any
lung disease that affects the performance of the proposed exercises.
To assess respiratory muscle strength, the volunteers remained in the standing position
using a nose clip. Respiratory muscle strength was obtained by the techniques of
measurements of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP), by
means of an analog manometer Generate brand, scaled to ± 300 cmH2O, equipped with nozzle
adapter, containing a hole 2 mm in diameter, serving as relief of muscles bocais.4 MIP valve
was obtained with the maximal inspiration preceded by maximal expiration to residual volume
level and MEP through the maximal expiration preceded by a maximal inspiration, to total
lung capacity. Were performed at least three maneuvers maximal inspiratory pressure and
maximal expiratory pressure, in order to obtain the greatest value from three acceptable.
The measurement of respiratory muscle strength occurred through an analog manometer (Ger-Air
®, São Paulo, Brazil), with scales - 300 to +300 cmH2O (calibrated), equipped with plastic
trachea 16 cm long and 2.4 cm internal diameter, hard plastic mouthpiece and drain hole
approximately 2 mm in diameter to dissipate the pressures generated by the muscles of the
face and orofaringe.13 the maximal inspiratory pressure (MIP) and expiratory pressures were
obtained maximum (MEP), carried a maximum of five times, acceptable and reproducible, and in
the standing position, using a nose clip, for a time of sustained three seconds. The value
of MIP was obtained from residual volume, and MEP from total lung capacity. Volunteers were
due verbal encouragement and if there were more than 10% between a measure and another, a
new difference maneuver was performed, considering the highest value since this was not the
último.14 Therapeutic Intervention - Pilates Method The training through the Pilates
exercises were performed in eleven weeks. The participants were instructed not to miss and
attend classes twice a week. Each class consisted of five exercises lasting 40 minutes each
lesson.
During the first four weeks (1 st to 4 th week) exercises performed were: Cat, Coffee Table,
Single legcircle, pelvic movements, contraction of the glutes and closure was performed with
posterior chain elongation range.
In the next four weeks (5th to 8th weeks) began a new series of exercises, which are:
Bridge, Side Table, Bridge hip roll with legextension, Abdominal - halfhollup, obliques, and
ultimately Stretching - Series of William's.
In the last four weeks of training (9th to 11th weeks) proposed a new series of exercises
involving: Beaststroke, Support heel Bridge - hip roll with leg extension, and Hundred
Squats with bat on the wall.
All exercises were performed during expiration. Statistical Analysis Descriptive data
analysis was performed, with a mean and standard deviation. For comparative analysis of the
data obtained in the pre-and post-intervention, the paired t test was applied (after
confirmed the normal distribution of the sample - Shapiro Wilk test). The level of
significance was set at 5%. The statistical program used was 18.0 SSPSS.
