Muscles that Move the Thigh01:20

Muscles that Move the Thigh

3.6K
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...

Muscles that Move the Leg

6.5K
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 of the Pelvic Floor and Perineum01:26

Muscles of the Pelvic Floor and Perineum

6.0K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Muscles of the Abdomen01:21

Muscles of the Abdomen

4.3K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...

Exercise and Muscle Performance01:27

Exercise and Muscle Performance

6.0K
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...

Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

5.0K
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....

Area of Science:

  • Biomechanics
  • Sports Medicine
  • Anatomy

Background:

  • The gluteus medius and minimus muscles are crucial hip abductors and stabilizers.
  • Swimming involves unique biomechanical demands due to the reduced-gravity environment.
  • Understanding muscle adaptations in swimmers is vital for injury prevention.

Purpose of the Study:

  • To compare gluteus medius and minimus muscle segment size and electromyography (EMG) activity between swimmers and non-swimmers.
  • To investigate potential adaptations in hip abductor muscle function due to swimming training.

Main Methods:

  • A case-matched control cross-sectional study was conducted.
  • Fifteen swimmers (elite and non-elite) and 15 matched controls were evaluated.
  • Electromyography and magnetic resonance imaging assessed gluteus medius and minimus segments during the gait cycle.

Main Results:

  • Swimmers exhibited distinct anterior gluteus minimus EMG activity patterns early in the gait cycle compared to controls.
  • Segmental differences in gluteus minimus activity observed in controls were absent in swimmers.
  • No significant differences in gluteus medius EMG characteristics or muscle size were found between groups.

Conclusions:

  • Preliminary findings suggest non-segmental gluteus minimus differences in swimmers, possibly due to reduced-gravity training.
  • These adaptations may alter deep stabilizer muscle function.
  • Altered muscle function could predispose swimmers to a higher risk of lower limb injuries during weight-bearing activities.
