Major Joints Used In A Tennis Serve Research Paper

One of my proudest achievements is joining the Varsity Tennis team. A lot of people told me that learning to play tennis at an advanced level within a year was impossible, but I payed them no heed and went to the park every day to practice. It was a rigorous year of tennis, but the key to success for me was with stubborn determination. I got blisters, callouses, and a couple of injuries, but all of my hard work paid off when I saw my name on the list.

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

The upper extremities are linked to the shaft by means of the shoulder girdle. These parts of the body includes; the shoulder girdle together with the shoulder blade and collar bone, the upper arm together with the humerus, the lower arm with the radius, the hand with carpus and lastly the metacarpus and fingers. During the implication of the different types of the serve, the extremities are used in different ways in that, they are involved in different movement and different types of the muscles in them are also required participating in the

Directions: Use your graded tests and Unit 4 & 5 notes to answer the following questions. You can find the answers for #’s 1 – 62 on Exam 1 (3rd Nine Weeks Exam) and #’s 63 – 100 on your unit notes. Write your answers in the space provided, below each question.

Without the movement of the lower body, a shot would end up anywhere but the back of the net. The lower body helps a player produce a straight shot so the ball winds up leaving the stick in the direction that the shooter intended.

In this phase the athlete is standing in a neutral position holding the ball. The metatarsophalangeal and interphalangeal (great and lesser toes) are held at slight flexion pressed against the ground by an isometric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The ankle is plantar flexed using an isometric contraction of the gastrocnemius and the soleus. The tibiofermoral (knee) joints are slightly flexed by a isomectric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The acetabularfemoral (hip) joint is held at a postion of slight flexion through an isometric contraction of the biceps femoris, pectineus, iliacus, and the psoas. The intervertebral (lumbar) joint is extended by an isometric contraction using the erector spinae. The atlantooccipital (cervical spine) joint is flexed by an isometric contraction erector spinae. Both scapulothroracic (shoulder girdle) joint is protracted by an isometric contraction of the serratus anterior and pectoralis minor. The glenohumeral (shoulder) joint is at internal rotation by an isometric contraction using the pectoralis major, latissimus dorsi, teres major, and the subscapularius. The humeroulnar (elbow) joint is at 90 degrees of flexion by an isometric contraction using the biceps brachii, brachioradialis, and brachialis. The radiocarpal (wrist left and right)

It's function is to hold the tendons in position. It's dysfunction can cause is tenosynovitis and carpal tunnel syndrome.

The UCL is crucial for valgus stability, maintaining the appropriate angle of the elbow away from the body, of the elbow and is the primary elbow stabilizer. As stated in Haan et al. (2011), “the AMCL is divided in two functional components and is taut throughout the full range of flexion and extension because the components are alternatively tightening throughout this range of motion. The posterior part of the AMCL is taut from eighty degrees flexion to full flexion; in contrast, the anterior part of the AMCL is taut in extension.”

The shoulder is a ball and socket joint which allows it a flexion and extension motion.
