骨盤底と横方向の腹部筋肉の測定信頼性と協力的な動き

[目的]この研究では、骨盤底と横腹部の筋肉の測定信頼性と協調的な動きを調べました。[参加者と方法]参加者は7人の健康な成人女性でした。横方向の腹部筋肉の厚さと膀胱の床の上昇は、活動運動中および抵抗運動中の以下の条件下で測定されました。静止状態、横腹部筋肉の最大収縮、骨盤底筋の最大収縮、および横方向の最大の共縮み腹部および骨盤底の筋肉。測定は、休憩中、および各運動条件下で行われました。[結果]横方向の腹部筋肉の厚さと膀胱床の上昇のクラス内相関係数は、すべての条件下で高い再現性を示しました。骨盤底筋肉の最大収縮は、耐性運動中の横方向の腹部筋肉と骨盤底筋の最大の共位との高い相関を示しました。すべての条件下で、横方向の腹部筋肉の厚さと膀胱の床の上昇の間に有意な回帰系統が見つかりました。回帰方程式は次のとおりでした：横方向の腹部筋肉の厚さ= 0.113膀胱床の高さ+0.377（R2 = 0.21）。[結論]この研究は、横腹部および骨盤底筋の測定の信頼性が高く、両方の筋肉が協調的な動きを示すことを実証しました。

[Purpose] This study examined the measurement reliability and cooperative movement of the pelvic floor and transverse abdominal muscles. [Participants and Methods] The participants were seven healthy adult females. Transverse abdominal muscle thickness and bladder floor elevation were measured under the following conditions during active exercise and during resistance exercise: the resting state, maximum contraction of the transverse abdominal muscle, maximum contraction of the pelvic floor muscle, and maximum co-contraction of the transverse abdominal and pelvic floor muscles. Measurements were taken at rest and under each exercise condition. [Results] The intraclass correlation coefficients of transverse abdominal muscle thickness and bladder floor elevation showed high reproducibility under all conditions. The maximum contraction of the pelvic floor muscle showed a high correlation with the maximum co-contraction of the transverse abdominal muscle and pelvic floor muscle during resistance exercise. A significant regression line was found between transverse abdominal muscle thickness and bladder floor elevation under all conditions. The regression equation was as follows: transverse abdominal muscle thickness=0.113 bladder floor elevation+0.377 (r2=0.21). [Conclusion] This study demonstrated that the measurement reliability of the transverse abdominal and pelvic floor muscles is high, and that both muscles exhibit cooperative movement.
