Anatomical Script of the Squat Technique Essay

The following muscles need to be stretched, lack of flexibility in which group causes the most injuries

The left metatarsophalangeal and interphalangeal (great and lesser toes) joints are held at slight flexion pressed against the ground by a concentric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The left talocrural (ankle) is plantar flexed using a concentric contraction of the gastrocnemius and the soleus. The right talocrural (ankle) is plantar flexed by a concentric contraction of the tibialis anterior, extensor digitorum longus, peroneus tertius. The left tibiofermoral (knee) joints are being extended by a concentric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The right metatarsophalangeal and interphalangeal (great and lesser toes) are being held plantar flexed due to an isometric contraction of the flexor halluces longus, flexor digtorum longus. The right tibiofermoral (knee) joints are flexed at a 90-degree angle by a concentric contraction of the biceps femoris, semitendinous, semimembranosus. During this phase the left acetabular fermoral (hip) joint is flexed due to an eccentric contraction of the rectus femoris, pectineus, iliacus, and psoas. The right acetabular fermoral (hip) joint is at slight extension due to a concentric contraction of the biceps femoris, semitendinosus, semimembranosus, and the gluteus

Participants in this study were healthy men and women ages 18-24. There were several criterions the participants had to meet before partaking in the study. Each individual had to successfully barbell back squat their own body weight for 1 repetition. Also participants were constantly observed by strength and conditioning coaches to ensure proper technique was applied to the barbell back squat. Lastly participants must have previously

As explained by Opar (3) the hamstring consists of three muscles, biceps femoris (BF), semitendinosus (ST) semimembranosus (SM), this composes a muscle group crossing the hip and knee joint that acts synergistically in extending the hip and flexing the knee.

Jumping (bilateral): Hip and knee is in extension, while ankle is in plantar flexion, and shoulder abduction and flexion while in the air.

Shoulder flexion/extension; Elbow flexion and extension; Use of the lower and upper back. Muscles involved include the latissimus dorsi, rhomboids, trapezius, deltoids and the pectorals.

Consequently, all of these muscles are what enables you to bend your knee and to extend your leg straight. During physical activity, if stretching a muscle beyond its limit, then an injury will appear. However, if the muscle is torn away from the pelvis, consequently that might require surgery. Another option for care is Physical Therapy, they benefit you by regaining flexibility and strength.

These muscles begin at the ischial tuberosity, which is at the bottom of the pelvis. The muscles meet at the knee joint and end at the lower leg, where they are joined together through connective tissue that attach the tendons to the bones like double-sided tape. The hamstring muscle groups work to help extend the leg back and provide motion at the knee. Due to the crossing

The key muscles that contract when executing an inversion are the tibialis posterior and tibialis anterior. The muscles that are required to perform a successful eversion are the fibularis brevis and fibularis longus. The next movement is dorsiflextion, which requires the flexion of tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles. Lastly, the motion of plantar flexion demands the contraction of the gastrocnemius, plantaris soleus, and the fibularis longus. Since the ligaments are weak, the surrounding muscles must be stronger in order to stabilize those ligaments or those ligaments might become very fragile and

A different type of work out is if you are not the best person at doing squats or fall while you trying to do them what you can do is put the ball behind you and use it as a support or back up for if you were to fall and struggle you have a safe cushioning to fall back on(note this is a ball and can move is done unyielding).one more example is the ball pass where you lay down and pass the ball from above your head to your feet

vastus medialis. Collectively the quadriceps muscle is the biggest in the human body and its purpose is to expand the knee. The specific task of the vastus lateralis muscle is to extend the lower leg and allow the body to rise up from a squatting position.(Hannan et al, 2000).

The biceps femoris is one of the three muscles including the semitendinosus, and the semimembranosus, that make up the group of muscles called the hamstrings. The hamstrings are located on the posterior side of the leg. The biceps femoris originates on the ischial tuberosity and inserts on the head of the fibula. The movement of the biceps femoris is responsible for the flexion of the knee and the external rotation of the lower leg. Flexion of the knee happens when the back of the foot is raised toward the back of the leg.

The anatomy is a major contributor to any injury. The three hamstrings are the semimembranosus, semitendinosus, and the biceps femoris. The hamstrings are responsible for flexing the knee and extending the hip

Many of the muscles of the foot originate in the leg. Tendons from these muscles attach in the foot and aid in the articulation of the joints. From the anterior leg, the extensor hallucis longus muscle, extensor hallucis brevis muscle, extensor digitorum longus muscle, and the extensor digitorum brevis act as extensors on the phalanges. From the posterior leg, the flexor hallucis longus muscle and flexor digitorum longus muscle act as flexors of the phalanges.

Rotation at the knee can only occur when the joint is in flexion. Medial, or internal, rotation is a slight “turning in” of the tibia, and the muscles that accomplish this are the semitendinosus, semimembranosus, and popliteus with assistance from the gracilis and sartorius. To slightly turn the tibia outward is called lateral (external) rotation, and the muscle that is solely responsible for this is the biceps femoris.
