An Anatomical Analysis of the Tennis Serve

balance of the body also flexion on the back leg when the ball is being released ending in a plantar flexion position .

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

In tennis serve the summation of forces is important as athletes wants to reach maximum speed and accuracy, which through the correct sequence of body movement this greater force will be generated (Geiblinger, 2016).

Humerus, Radius, Ulana (arms): To support your wrist and fingers when hitting the ball, it also provides power when hitting the ball.

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)

during these movements, the angles of those joints, as well as the muscles involved during the

Tennis is a game of speed and reflex. It uses a lot of muscle memory. You need to be able to move quickly and effectively to reach the ball quickly and hit it. Thus it takes quick reaction time and reflexes to play at higher levels. Tennis drills and practices train your muscles to react faster, smoothly and naturally. During fast volley bouts your muscles often react

Need Statement: Many of us are going into the PT/OT career field and if we have a better understanding of tennis, maybe it can help us when dealing with patient’s injuries.

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.

Course Description : Lateral Epicondylitis is a condition that accounts for between 1-3 % of all musculoskeletal complaints in an MDs office. To date limited research exists to explain the efficacy of a clear approach in its assessment and management. This course will expose the participant to current concepts in the literature surrounding the etiology of the condition, the limited evidence surrounding the special tests for lateral epicondylitis and the role of proximal structures in these tests. Further discussion will focus on the importance of ruling out proximal conditions and the roles that each plays in elbow pain. The instructors will then shift focus to current

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

As we all know, America is a nation of sports enthusiasts. Most Americans participate is some kind of sporting event, either as a spectator or as a competitor. In the pantheon of great American sports, there is one that stands out. It has been called the great American pastime. Yes, that great sport known as tennis. Tennis requires a mastery of many skills to be able to play competitively, but the primary skill needed to win in tennis is the serve. The serve is the primary offensive weapon used I tennis, because it is the only time when a player gets to put a ball into play. The player controls the speed, the placement, and the spin of the ball. With proper procedure, the serve can win many points and games for the server. The technique

Playing tennis involves more muscles than simply your arm and wrists. It involves a series of complex movements that start with your feet and ends up swinging a tennis racket. It requires a honed and well-trained muscular system to perform with the required power and speed needed. The muscular system is one of the most important systems involved in the sport of tennis. The muscular system is the tissue of fibres around your bones. This is a main part of tennis because specifically these muscles will put force on the bones and pull them. This will result in the tennis player getting more power behind there hit and also helps the play with moving around the court in a quicker pace.

Serving a tennis ball left handed requires many skills such as Fine/Gross, Open/Closed and Discrete/Serial/Continuous.

The authors conducted this study to see how and when this ability in humans evolved by studying the mechanics used in throwing. They compared the mechanics of throwing of humans to that of chimpanzees. The authors said that previous studies found that the internal rotator muscles are responsible fort the power of the human throw. The investigators hypothesize that the elastic energy storage is the important source for this power. They also stated that other features of the human shoulder are important in storing this energy and
