Muscles And Trauma Case Study: Chinese Delivery

* The bending of the knees and the use of the leg muscle groups to perform the skill.

1 . Describe the Major bones, muscles,joints and joint actions used to perform this movement skill and how they influence the way the body moves.

In order for maximum force to be generated, a tennis player needs a good stable base from where they can begin the movement. The tennis serve begins with flexion of the knee joint caused by the hamstrings. Then comes extension of the knees as well as hip flexion to start the movement - both of these movements are initiated by the quadriceps. The Erector Spinae muscle causes trunk extension to allow the abdominals to fully flex the trunk and generate the force that is then transferred to the upper body. The deltoids and pectorals major are used to flex the shoulder. These muscles are used to accelerate the whole arm while also stabilising the shoulder. Once the arm has begun to accelerate towards the ball, the tricep brachii is then used to

A long journey followed his escape that required much perseverance. Matt had to continue on even when he was tired because he didn’t know who was after him. He also had to climb an enormous cliff where he grew very tired, but then he decided to persevere. He no longer felt exhausted or discouraged or anything else except a towering fury to survive. (251) This taught Matt much perseverance which made him stronger than he was at the beginning of the story. Through Matt’s new-found patience he was able to escape Opium and make it to

The movements involved in the action of standing up is when the muscles contracting. The muscles that are needed to perform these actions are the glutes, hamstrings, and the quadriceps.

of your leg…. though your calves…. and through the muscles of the feet and ankles and out of your

The most vivid injury in my mind is one that still shows today on my right ankle.

You can have many muscle injuries, so we are going to be diving into some of the main muscle injuries.

They compel him to do stunts they believe are ghastly, for example, grabbing dead creatures in the street, recounting appalling stories, watching violence motion pictures, and carrying on in class. Matt's companions obviously weight him, utilizing the way that his

The female exerciser begins executing the bird dog while positioned on her hands and knees. She raises her left arm while simultaneously extending her right hip and knee. The muscle fibers of her anterior deltoid engage and act as the agonist for shoulder flexion while the gluteus maximus engages as the agonist for hip extension. The quadriceps femoris group act as the agonist for knee extension. The antagonists for shoulder flexion are the posterior deltoid, latissimus dorsi, teres major, pectoralis major, and the triceps brachii. The antagonist for her hip extension is the iliopsoas while the hamstring group is the antagonist for knee extension. The upper fibers of her pectoralis major, along with the biceps brachii

The muscles that are considered to be the prime movers in order to do a pull up is the Latissimus dorsi, biceps, front deltoid, terse major to start the movement in order to bring the body upward towards the bar. Once you get close to the top of the bar the synergist muscles will kick in order to help support the prime muscles movers. Those muscles would be the rhomboids and the trapezius to get involved to help and add thickness and strength to the back. The stabilizers for the supinated chin up will be the abdominals and obliques.

The recovery stage begins between the 6 and 12 o’clock position in the pedal revolution. There is some knee flexion to help bring the pedal back to the top but helping that flexion is the greater downward force being placed on the opposite pedal, by the opposite leg. The muscles that help return the foot to the top range from the hamstrings and calves at the bottom of the stroke, pulling the foot backwards, to the quadriceps at the top, lifting the foot and knee back to the 12 o’clock position. There are several muscle groups that are used in the lower extremities to pedal a bicycle, which are the Quadriceps Femoris, Hamstrings, Gluteals, Gastrocnemius, Soleus and hip flexors. The upper extremities along with the transverse abdominus, oblique abdominal muscles, torso, and the lower back are the stabilizers for pedaling a bike (Lee &

Breathe in, while slowly lifting your lower back, middle back and upper back off the floor. Gently roll in your shoulders. Touch your chest to your chin without bringing the chin down. Support your weight with your shoulders, arms and feet. Feel your buttocks firm up in this pose. Both your thighs should be parallel to each other and to the floor.

From the biomechanical testing my client exhibits normal ability to adapt and lock his foot, as well as respond to vertical loading. He also has no issues with his knee position. However, he will want to address his postural issues. The lordotic posture could be caused by tight hip flexors, and erector spinae group. It also could be coupled with weak or lengthened abdominals and hamstrings. This is coined as Lower Cross Syndrome (Janda, 1996). Because of the lordotic posture I will want to test for muscles strength and flexibility know which muscles is most at fault and address it. Another point to note is the forward upper cross syndrome. This could be due to years of studying and looking at a computer or phone. He could have week neck deep neck flexors and lower traps while his upper traps and sternocleidomastoid could be tight.

It seems to be that I would work against gravity and not let myself go low enough in the position, I would be folding from the hips but still be closer to the standing position instead of letting myself lower down. “No account of the conditions under which muscles work would be complete were on to ignore the influence of gravity.” (Basmajian 1998, p.123). Noticing this has made a bit more sense in why my position was more upright than others including the tutors. Upon further understanding, it would make sense not to push against the gravity and ease up in the lower limb, release my knees and send them forwards which sends my pelvis down and then fold in the hips to continue lowering the height. When folding the knees, it is important to make sure your knees are releasing in the direction of the toes and not inwards toward the ankles as it causes stress in the knee
