OBJECTIVE: To examine the immediate effects of two types of trunk muscle exercises on chest mobility and trunk muscle activities. METHODS: Fourteen healthy men randomly performed trunk side flexion and draw-in exercises using a cross-over design. The chest kinematic data and trunk muscle activities were measured before and after each intervention. RESULTS: After the side flexion, upper and lower chest mobility significantly decreased and superficial trunk muscle activity significantly increased during the maximum pelvic anterior tilt. Additionally, after the draw-in, upper chest mobility significantly increased during the maximum pelvic anterior tilt. CONCLUSIONS: Increased activity of the superficial abdominal muscles might be the limiting the chest mobility during maximum pelvic anterior tilt. Conversely, the facilitation of deep trunk muscles might increase upper chest mobility during the maximum pelvic anterior tilt.
