Brief Summary

This study expects to provide a new alternative way to improve the muscle activation, strength and activation of transverse abdominis in abdominal draw-in maneuver combined with blood flow restriction.

Conditions

Blood Flow Restriction; draw-in Maneuver; Transverse Abdominis

Outcome Measures

Primary Outcomes (1)

• Muscle Thickness Change of Transverse Abdominis

  muscle thickness change on week3, 4 and 5 compared with baseline

  3,4,5 weeks

Secondary Outcomes (2)

• Internal Oblique Thickness Change

  baseline,3,4,5 weeks

• External Oblique Thickness Change

  baseline,3,4,5weeks

Study Arms (2)

blood flow restriction

EXPERIMENTAL

An inflatable cuff (14 cm in width \* 84 cm in length) is warped around abdominal muscles below ribs which may cause to at least 60% restriction of blood flow detected by Power Doppler ultrasonography. All participants are instructed to perform abdominal draw-in maneuver both condition of BFR and BFR-free twice a week, for six weeks.

Behavioral: blood flow restriction

SHAM COMPARATOR

an inflatable cuff (14 cm in width \* 84 cm in length) is warped around abdominal muscles below ribs without inflation. All participants are instructed to perform abdominal draw-in maneuver.

Behavioral: sham blood flow restriction
