Q1.Major Bones Used In A Tennis Serve Metacarpals and Phalanges (fingers) : to grip and hold the racquet . Carpals (Wrist): To flick and move the racquet. Humerus, Radius, Ulana (arms): To support your wrist and fingers when hitting the ball, it also provides power when hitting the ball. Clavicle, Scapular and the Upper Humerus (shoulder): Needed to pivot and for serving. Pelvis, sacrum, and coccyx (Hip): Needed to align your body to hit the ball. Tarslas, metacarapals, phalanges (foot): to move, run, balance move and for foot wear. Talus (ankles): to start stop quickly. Tibia, patella (knee): to bend over to hit the lower shots.

Major Muscles Used In A Tennis Serve Biceps Triceps Quadrcieps- Intermediate fast switch muscle (used to run to hit the balls). Hamstrings- Predominatly fast switch muscle (used to run and bend for low shots). Gastrocnmemius- used to stop or jump and serve Abdominals- are used to twist and move your upper body Deltoids- used to serve for a overhead smash.

The Hexagon Test
To assess the agility and coordination of a tennis player.
How does this work?
1. The player remains amidst the hexagon confronting forward, as they ought to for the length of the test.
2. Start by bouncing forward over the tape with both feet and instantly once more into the hexagon when the charge "Prepared Steady-Go" is given.
3. At that point, keeping on confronting forward, the player hops throughout the following side and once more into the hexagon. This example will be proceeded by hopping over every one of the six sides and back to the center for three full revolutions.The test starts at Level 1 taking after a brief clarification on the
It's function is to hold the tendons in position. It's dysfunction can cause is tenosynovitis and carpal tunnel syndrome.
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.
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
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.

18. Canvas contains practice exams and answers. What is the answer to question 6 on the Chapters 1, 2 and 3 practice exam?
Complete the following practice exercises from Chapter 1 and 2 and submit them to your instructor. This assignment will be graded as a completion only to allow you to transition into the subject matter during the first week. The instructor will post the answers to these exercises by the end of Day 6 for you to check your accuracy and comprehension on the subject matter. Exercises:
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 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
The shoulder is a ball and socket joint which allows it a flexion and extension motion.
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)

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
