まとめ
運動による筋肉損傷 (EIMD) は,運動選手の横断で膝と股関節の生体力学を変化させます. EIMDは減速の要求を膝から股関節にシフトさせ 負傷リスクを高めます
科学分野:
- スポーツ医学
- バイオメカニクス
- 運動 生理学
背景:
- 運動による筋肉損傷 (EIMD) はチームスポーツで一般的です.
- 怪我を防ぐには EIMDが 運動に与える影響を 理解することが重要です
研究 の 目的:
- チームスポーツ選手の3次元サイドカットバイオメカニクスとタスク達成に対するEIMDの影響を調査する.
主な方法:
- 16人のチームスポーツ選手は,多方向走行の前と48時間後に45°の横切りをしました.
- 3Dモーションキャプチャとフォースプラットフォームで,関節運動,モメント,および地面反応力 (GRF) のインパルスが測定されました.
- 分析はヒップと膝関節の動きと サイドカット試験の成功時の瞬間に焦点を当てた.
主要な成果:
- EIMDは膝の内部の回転と 誘拐の範囲を増加させました
- 膝のピークエクステンサーモントは減少し,股関節と膝のエクステンサーモントの比率はEIMD後に増加した.
- 女性のGRFインパルスは著しく高く,減速能力の低下を示した.
- タスク達成とサギタル平面運動はEIMDの影響を受けなかった.
結論:
- EIMDは下肢の バイオメカニズムを変化させ 膝から股関節に減速します
- 医療従事者は,EIMD後の前頭部と横関節の動きを増やすことを検討し,怪我のリスクを軽減する戦略を提示する必要があります.

01:16Bones of the Lower Limb: Femur and Patella
8.2K
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...

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

01:27Exercise and Muscle Performance
6.2K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:23Muscles that Move the Leg
6.9K
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...

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....

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
