  • Physical consequence of stroke often include hemiplegia and respiratory muscle weakness, limiting exercise capacity and contributing to poor outcome. (pnmedical.com)
  • Based in a positive correlation, MIP can directly influence exercise capacity after stroke and improve outcome and survival. (pnmedical.com)
  • There is conflicting research on the performance benefits of RMT, some challenging the assumption that an increase in inspiratory muscle fitness translates to better work capacity and athletic performance. (wikipedia.org)
  • Exercise capacity is reduced since the ability to take deep breaths is compromised. (karger.com)
  • When taking a gander at the solid help of the pelvic floor it is valuable to take a gander at different muscles associated with its right capacity. (aseko.org)
  • Williamson and co-workers linked central command to activation of the insular cortex [ 19 ], and showed that this brain area was involved with the regulation of the autonomic nervous system during exercise [ 20 ]. (springer.com)

  • We tested the hypothesis that brain areas involved in cardiorespiratory control could be activated during the acute physical exercise. (usp.br)
  • In the present study, we showed that after running acute exercise there is an intense activation of brain areas important for the cardiorespiratory control. (usp.br)
  • Besides that, the chemosensitivity neurons of the RTN are activated after acute running exercise, showing that these particular subset of neurons have a role of the respiratory control during exercise, through the involvement of the "central command" of the hypothalamus. (usp.br)
  • Muscle atrophy occurs with a reduction in fiber cross-sectional area. (biomedcentral.com)
  • In that study the reduction in strength was proportional to the reduction in thigh area (ie the reduction in strength was entirely due to muscle atrophy). (biomedcentral.com)
  • Despite recent progress in the understanding of mediators and mechanisms involved in muscle wasting, effective and universally accepted treatments by which muscle atrophy can be prevented or reversed are still lacking. (researchgate.net)
  • When the muscles cannot receive signals from the lower motor neurons, they begin to weaken and shrink in size (muscle atrophy or wasting). (nih.gov)
