The article presents the analyze of exercises based on the volitional activation of the abdominal muscles without motor activity: «abdominal bracing» and «abdominal hollowing». Electronic resources used are: «KoreanScience», «Scholar google», «PubMed», «Researchgate». Muscle biopotentials in electromyography, muscle thickness in ultrasound, and muscle elasticity in elastography were used to assess the immediate effects of exercise. In randomized clinical trials, positive effects were confirmed by the results of the control exercises, increased muscle area on MRI images, reduced pain and social maladjustment by questionnaire methods. The possibility of using «abdominal bracing» for complex activation of the abdominal muscles and «abdominal hollowing» for the selective activation of the transverse muscle against a background of low intra-abdominal pressure was established.
Keywords: abdominal bracing, abdominal hollowing.
