Inspiratory Muscle Training in Wheelchair Basketball Players
Condition: Respiratory Muscles; Breathing Exercises; Athletic Performance; Athletes; Aerobic Capacity
MeSH terms: Respiratory Aspiration
Study type: Interventional

Summary: 
      Investigate the effects of Inspiratory Muscle Training on the physical performance and
      cardiorespiratory variables of wheelchair basketball players.
    

Detailed description: 
      The respiratory system has been touted as a limiting factor of physical performance during
      high intense physical exercises. This limitation is related, among other things, with the
      fatigue of respiratory muscles. The fatigue of these muscles during physical exercise
      generates many physiological reflex activation culminating in reduced blood flow to the limb
      muscles, resulting in decrease in muscle performance. Researchers showed that the inspiratory
      muscle training (IMT) is able to generate improved of athlete's physical performance.
      However, when it comes to wheelchair athletes there are still divergent views on the effects
      of IMT on the physical performance. Thus, this study aims to evaluate the effects of IMT on
      the physical performance and cardiorespiratory variables of wheelchair basketball players.
      For this purpose, the investigators will select 40 wheelchair basketball players of both
      genders. The participants will be allocated blindly and randomly into two groups that differ
      by the proposed interventions. In IMT Group, the participants will be submitted to a IMT
      program with inicial load of 50% of maximal inspiratory pressure (MIP); the SHAM Group will
      be submitted to a simulated IMT with load of 15% of MIP. All participants will pass through
      the same evaluation procedures before and after the interventions, so that the investagators
      can evaluate the benefits generated by the IMT on the physical performance and
      cardiorespiratory variables of wheelchair basketball players.
    

Intervention name(s): Inspiratory pressure-threshold muscle training device.; nspiratory pressure-threshold muscle training device.
Intervention type(s): Device; Device
Intervention description(s): The participants who will be allocated in this simulated intervention group will have to do a simulated inspiratory muscle training protocol through the inspiratory muscle exerciser POWERbreathe, model Sports Plus Heavy Resistance (POWERbreathe; HAB International Ltd., Warwickshire, United Kingdom) for 12 weeks five times at week and twice daily, with a load of 15% of maximal inspiratory pressure without progression. In each session will be requested to the volunteers make 30 slow breaths, which will be constantly supervised by the researchers.; The participants who will be allocated in this intervention group will have to make a inspiratory muscle training protocol with progressive loads through the inspiratory muscle exerciser POWERbreathe, model Sports Plus Heavy Resistance (POWERbreathe; HAB International Ltd., Warwickshire, United Kingdom) for 12 weeks five times at week and twice daily, with an initial load of 50% of maximal inspiratory pressure, progressing to 60% after the fourth week, and 70% after the octave week. In each session will be requested to volunteers who performed 30 maximal and prolonged inspiration, maintaining the diaphragmatic breathing, which will be constantly supervised by the researchers.
