Effect of Inspiratory Muscle Training on Cardiopulmonary Capacity in Wheelchair Rugby Athletes
Condition: Breathing Exercises; Disability Physical; Athletes
MeSH terms: Respiratory Aspiration
Study type: Interventional

Summary: 
      The goal of this clinical trial is to learn about in inspiratory muscle training on
      cardiorespiratory capacity, pulmonary function, respiratory muscle strength, sports skills,
      and quality of life of wheelchair rugby athletes. The main question[s] it aims to answer are:

        -  Are the wheelchair rugby athletes show better results in cardiopulmonary assessment
           tests in safety and effort, in the post- inspiratory muscle training period, when
           compared to their results in the pre-inspiratory muscle training period?

        -  Is inspiratory muscle training capable of increasing ventilatory capacity at rest and
           during exertion?

      Participants will be evaluated through questionnaires, laboratory and field tests, such as:

        -  Pulmonary function (spirometry),

        -  Inspiratory muscle strength (manovacuometry),

        -  Cardiorespiratory capacity under exertion (cardiopulmonary exercise test),

        -  Wheelchair rugby specific skills (Beck Battery)

        -  Quality of life (WHOQOL-DIS) .
    

Detailed description: 
      People with physical-motor disabilities, dependent on wheelchairs, have less mobility
      compared to people without disabilities, which can, in turn, have a direct and negative
      impact on the aerobic capacity and health of these individuals. Wheelchair Rugby (WCR)
      practitioners, as well as other sports, seek constant performance improvement, given the need
      to achieve better results in competitions. There has been an increase in the evaluation of
      parameters that may be related to better sports performance, as well as interventions that
      improve such performance. In relation to collective sports, such as WCR, the evaluation of
      important parameters such as maximum oxygen consumption during effort, maximum heart rate
      achieved and anaerobic limits, which enable adequate training adjustment, has gained
      prominence. Different interventions, such as inspiratory muscle training (IMT), aim to
      improve respiratory capacity and, consequently, cardiopulmonary capacity in savings and
      maximum effort. Therefore, this is a clinical study, with the objective of verifying the
      impact of IMT on cardiopulmonary performance, spirometric variables at rest and during
      effort, performance in field tests (Beck Battery) and quality of life in WCR athletes. Rugby
      athletes will be recruited in wheelchairs from teams in Rio de Janeiro, to perform two daily
      sessions of 30 forced inspirations followed by long, but not maximum, expirations, with a
      load adjusted between 50% and 60% of maximum inspiratory muscle strength, five times a week
      for six weeks.
    

Intervention name(s): Inspiratory Muscle Training
Intervention type(s): Other
Intervention description(s): Inspiratory muscle training was performed for six weeks. Athletes performed two daily sessions of 30 forced inspirations followed by long but not maximal expirations, with load adjusted between 50% and 60% of maximum inspiratory pressure, five times a week. A specific device was used for this purpose (Classic, Powerbreathe, United Kingdom), with light or medium resistance adjustment, depending on the subject's maximum inspiratory pressure.
