The influences of position and forced respiratory maneuvers on spinal stability muscles

Abstract

[Purpose] The purposes of this study were to investigate the influences of position on %MVIC of spinal stability muscles to establish for the most effective breathing pattern for activation of spinal stability muscles in order to provide an additional treatment method for use in spinal stability exercise programs. [Subjects and Methods] Thirty-three healthy subjects performed quiet breathing and four different forced respiratory maneuvers (FRM); [pursed lip breathing (PLB), diaphragmatic breathing (DB), combination breathing (CB) and respiration muscle endurance training (RMET)] in both standing and sitting positions. %MVIC of them (the multifidus (MF), erector spinae (ES), internal oblique/transversus abdominis (IO/TrA), external oblique (EO), rectus abdominis (RA) measured. [Results] IO/TrA, MF and EO showed greater activation in standing than in sitting, while RA and ES showed greater activation in sitting than in standing. RMET induced significantly greater activation of spinal stability muscles then other breathing patterns. %MVIC changes of muscle activities induced by FRM were independent of position with a few exceptions. [Conclusion] The increased respiratory demands of FRM induced greater activation of spinal stability muscles than QB. RMET was found to be the most effective breathing pattern for increasing the activation of the spinal stability muscles.

Pistol Shooting Performance Correlates with Respiratory Muscle Strength and Pulmonary Function in Police Cadets

“…Although the body may respond differently depending on the intensity, nature, and duration of the stressor, as well as several internal factors of the individual who experience it [84,85], body sway is a highly sensitive action and is affected by stability muscles. The respiratory muscles act as one of the spinal stability muscles [86] and optimize postural sway [68,73,87]. Studies have reported that the diaphragm and abdominal muscles produce a hydraulic effect that aids spinal stabilization by stiffening the lumbar spine with increased intra-abdominal pressure in the abdominal cavity [88].…”

“…Therefore, the respiratory muscles are important in providing stability to minimize unwanted movements during shooting, albeit with a different mechanism [42]. Some reports show that an increase in the strength and endurance of these muscles might increase spinal stability [86,89].…”

The impact of the pelvic floor muscles on dynamic ventilation maneuvers

“…The diaphragm, the principal muscle of respiration, has been reported to act as one of the spinal stability muscles, and the IO, EO, and PFM are also activated to increase respiratory capacity with the diaphragm. The spinal stability provided by these muscles is generated from their co-contraction, which increases IAP; these muscles also function as respiratory muscles by increasing their activities when respiratory demand increases 11 ) . The present study examined the effect of contraction of the PFM (act as respiratory muscles or stabilize the trunk) on respiratory muscle activity and vital capacity.…”

Influência do músculo diafragma no controle postural, na propriocepção e na dor lombar

“…No que diz respeito às amostras dos estudos descritos nas tabelas I e II, foram avaliados indivíduos de ambos os sexos, eutróficos [1,3,7,8,[11][12][13][14][15][16][17] e com dor lombar [3,5,7,11,13,17]. A idade da população estudada variou entre 18 e 71 anos, e o tamanho amostral entre 5 e 150 indivíduos, resultando em um total de 421 indivíduos.…”
