The Upper Body Muscles Used in Tennis

Transcript of The Upper Body Muscles Used in Tennis
with the motion of the
forehand swing. It flexes
the arm at the elbow. The Braichialis muscles induces the flexes of the forearm at the elbow. Pectoralis Major Biceps Brachii Brachioradials Brachialis Origin: Clavicle, sternum Insertion: humerus Origin: Scapula Insertion: Radius Joints: Origin: Humerus Insertion: Radius Joints: Origin: shaft of the humerus Insertion: Ulna Joints: The external Oblique
are the lateral parts of
the abdomen that is
first used when working
towards the ball. The External
Oblique Origin: Lower Ribs Insertion: Pelvic Girdle The Orgin, Insertion,
And Joints used Triceps brachii
Humerus and scapula
Joint: Hinge The Backhand stroke
uses more of the posterior muscles
unlike the forehand.
The triceps brachii, deltoid,
and the latissimus dorsi. The Latissimus dorsi, an extensor,
is a part of the posterior region that contributes
in a more dynamic backhand stroke.
It is responsible for pulling
the shoulder downward and back.
It also pulls the arms back like
in swimming, climbing,
rowing or tennis. The Triceps, an extensor,
is the primary extensor of the elbow.
It produces a more dynamic stroke
because when the racket is swung,
it uses the biceps to flex the forearm
and in return, the triceps extend
which gives it a straight
position of the racket. The Origin, insertion and joints uned Latissimus dorsi
Origin: sprines of sacral,
lumbar, and lower thoracic vertebrae,
iliac crest, and lower ribs
Insertion: humerus THE TENNIS SERVE The serve is very similar to the forehand stroke but relies more on the shoulders. Serving starts with the feet as the upper body begins to prepare for the impact of the ball on the racket. The External Oblique muscles are used again to reach the ball for impact with the tennis racket. The Deltoid, an abductor muscle is used
when the ball is the highest point
where the racket makes
contact with the ball. The teres minor and major are extensor muscles that are used along with the deltoid. The teres major extends and adducts as it rotates the arm medially whereas the teres minor just rotates the arm laterally. Teres major
Humerus Origin, Insertion, and Joints Used Teres minor
Insertion: Humerus These muscles assist with the proper power and stroke of the serve causing a full and successful result. The upper body requires a great teamwork of muscles to make playing tennis accurate with the strength and speed required. hinge hinge hinge The Backhand Stroke The flexor digitorum
superficials in the arm work together in hitting the ball.
