Contractions of specific abdominal muscles in postural tasks are affected by respiratory maneuvers
Why the study?
Do respiratory maneuvers affect the reaction time of abdominal muscles in a postural task?
Population

Implication
Respiratory phase may modulate anticipatory abdominal muscle timing; leaves open effects on clinical stability or training protocols.
Structured PICO
Do respiratory maneuvers affect the reaction time of abdominal muscles in a postural task?
P
Population
Subjects performing postural tasks (details not specified in abstract)
I
Intervention
Respiratory maneuvers (inspiratory loading, forced expiration below functional residual capacity, and a static glottis-closed expulsive maneuver)
C
Comparator
Quiet breathing
O
Outcome
Electromyographic (EMG) onsets of the abdominal muscles and deltoid in response to shoulder flexionsurrogate
Changes occur in early anticipatory contraction of transversus abdominis during respiratory tasks, which cannot be explained simply by existing activation of the motoneuron pool.
