vastus lateralis การใช้

• It lies between the vastus intermedius and the vastus lateralis.
• The vastus lateralis is an example of unipennate architecture.
• This study looked at the muscle specific tension in the quadriceps femoris and vastus lateralis of forty-two young men.
• Type I muscle fiber characteristics ( area, number of capillary contacts, fiber area / capillary contacts ) of the vastus lateralis are unaffected by age.
• However, the study did not show comparative upper body muscle mass or strength increasing nor was there any significant increase in quadriceps femoris other than the vastus lateralis.
• Biopsies of the mid-portion of the " m . vastus lateralis " were obtained by means of a 6-mm biopsy needle with suction assist.
• Between the vastus lateralis and the adductor magnus two muscles are attached viz ., the glut鎢s maximus inserted above, and the short head of the biceps femoris arising below.
• Anterior compartment muscles of the thigh include pectineus, sartorius, and the four muscles that comprise the quadriceps muscles-rectus femoris, vastus medialis, vastus intermedius and vastus lateralis.
• The anterior compartment of thigh contains the sartorius muscle and the four quadriceps : the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis, along with the articularis genus.
• Results showed significant increases in activation of tibialis anterior, gastrocnemius, soleus, rectus femoris, vastus lateralis, medial hamstring, biceps femoris, and gluteus maximus before foot strike.
• In U . S . studies, muscle biopsies were obtained before and after flight from the m . vastus lateralis of 8 astronauts after 5-and 11-day missions.
• From the medial lip of the linea aspera and its prolongations above and below, the vastus medialis arises; and from the lateral lip and its upward prolongation, the vastus lateralis takes origin.
• While the muscle has variable presentations, it consistently originates at the proximal femur, runs between the vastus lateralis and vastus intermedius muscles, and inserts distally at the medial aspect of the patellar base.
• Due to being the deeper middle-most of the rectus femoris can, nor is it accessible to manipulate with massage therapy to stretch the fibres sideways as the vastus lateralis and vastus medialis are.
• A similar reduction in the activity of citrate synthase, but not phosphofructokinase, has been detected in the vastus lateralis, indicating a significant impairment of the oxidative capacity in this muscle after unilateral limb suspension.
• Additionally, the loss of explosive leg power was associated with a substantial reduction in the electromyography ( EMG ) activity of the m . rectus femoris, m . vastus lateralis, and m . vastus medialis.
• The largest difference in muscle fiber size between AAS users and non-users was observed in type I muscle fibers of the vastus lateralis and the trapezius muscle as a result of long-term AAS self-administration.
• Historically considered a part of the vastus lateralis, the tensor vastus intermedius muscle is innervated by an independent branch of the femoral nerve and its tendinous belly can be separated from the vasti lateralis and intermedius muscles in most cases.
• This discrepancy may reflect the effects of exercise countermeasure protocols carried out by the astronauts during the later flight and the examination of muscles different from those studied in the earlier flight ( gastrocnemius and soleus vs . vastus lateralis ).
• The " inferior border " corresponds to the line of junction of the base of the trochanter with the lateral surface of the body; it is marked by a rough, prominent, slightly curved ridge, which gives origin to the upper part of the vastus lateralis.
