まとめ
ブルガリアのスプリット・スクワット (BSS) は,ヒップ伸縮の重要な要因である,重要な後肢抵抗 (MRL) を生み出します. 姿勢の幅と幹の傾きを調整することで ターゲットを絞ったヒップエクステンサートレーニングに最適化できます
科学分野:
- バイオメカニクス
- 運動科学
- 筋力 と 体調
背景:
- ブルガリア スプリット スクワット (Bulgarian split squat, BSS) は,股関節の伸縮に重点を置くことで知られている一方的な運動です.
- 前部股関節拡張 (MHE) に対して,理論的な後部腿導出モメント (MRL) が提案されているが,実験的に検証されていない.
- MRLに影響を与える要因を理解することは,ヒップエクステンサートレーニングのためのBSSを最適化するために不可欠です.
研究 の 目的:
- BSSで裏足から派生したモメント (MRL) の存在を実証する.
- MRLに対するスタンス幅とトランク傾斜の影響を調査する.
- MRLと頭と腕と幹のセグメントによる重力モメント (MHAT) が,総延伸抵抗に与える影響を確認する.
主な方法:
- 訓練された9匹のオスは,体重のBSSを様々な姿勢幅 (幅,狭さ) とトランク傾斜 (追加,自然,縮小) で実行した.
- モーションキャプチャーとフォースプラットフォームは,MRL,MHAT,MHEを定量化するために使用されました.
- 分析は,MRLの大きさと,総外部耐性に対するMRLの割合に焦点を当てた.
主要な成果:
- MRLはスタンス幅に応じて49~86Nmの合計抵抗に大きく貢献した.
- MRLは,総耐性 (MHAT + MRL) の62~98%を占めた.
- 狭い姿勢では,より直立したトランク姿勢でMRLが増加しました.
結論:
- この研究は,BSSにおける実質的な耐性成分としてのMRLに対する最初の実験的証拠を提供します.
- この結果は,MRLとMHATがMHEと密接に一致することを示す,提案された機械モデルを支持します.
- 臨床医は,MRLを調節するために姿勢と幹の姿勢を操作し,前向きな傾斜で部伸縮器の負荷を高めることができます.

Muscles that Move the Leg

The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Muscles that Move the Thigh

The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Bones of the Lower Limb: Femur and Patella
2.9K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static equilibrium. Indeterminate structures have more unknown forces and reaction forces than equations of static equilibrium that can be used to determine them. Indeterminate structures are often used in engineering to create complex, efficient, and aesthetically pleasing structures. There are various types of indeterminate structures used in engineering and...

When analyzing structures or systems at rest, it is necessary to ensure they are in equilibrium. This is where the vector and scalar equations of equilibrium come into play. These equations are crucial in ensuring a structure is stable and will not collapse or fall apart. The vector and scalar equations of equilibrium provide a framework for analyzing the forces acting on a body.
According to the vector equations of equilibrium, the vector sum of all the external forces acting on a body must...
