Voluntary Contraction of the Abdominal Muscles Increases Hip Muscle Activation During Lower-Extremity Exercises: A Critically Appraised Topic.

Abstract

Existing studies have posited that incorporating abdominal enhancement techniques during lower-extremity exercises might mitigate compensatory pelvic motions and enhance the engagement of specific hip muscles. Does performing lower-extremity exercises with abdominal enhancement techniques increase hip muscle activation levels in healthy individuals? Summary of Key Finding: After the literature review, 4 cross-sectional studies met the inclusion criteria and were included in this critically appraised topic. There is moderate evidence to support that prone hip extension with abdominal enhancement may increase gluteus maximus and hamstring muscle activity. Gluteus medius activity may not be affected by abdominal enhancement during hip abduction exercises. Strength and Recommendation: The collective findings from the 4 cross-sectional trials indicate that the incorporation of abdominal enhancement techniques during lower-extremity exercises may have the potential to enhance targeted muscle activation levels in healthy individuals. Further research is recommended to establish more robust conclusions.
