The muscles that allow for this internal rotation of the shoulder from the racket drop position to the contact point are the Subscapularis, Latissimus Dorsi, Teres Major and>Pectoralis Major muscles. 2) Pronation of Racket-Arm's Elbow The second noticeable movement that takes place during this second transition of the forward swing is pronation of the racket-arm's elbow.
The muscles used when playing tennis are: In the lower body: calves, hamstrings, quads, and glutes. In the core: abs, obliques, erector spinae, and latissimus dorsi.
The 3 major types of serves used in tennis are the flat (limited spin), slice (sidespin), and topspin “kick” serves (Figure 2). It is important to understand the differences in these serves and how they may affect the kinetic chain muscle activation patterns and summation of forces.
The muscles that help get your racket arm into this position are collectively known as the external shoulder rotators and their names are the Teres Minor and the Infraspinatus muscles. 3) Transfer of Weight Between Feet The other noticeable movement that occurs in going from the stance position to the trophy pose position is the transfer of weight that occurs between your feet.
Shoulders, Upper Arms, Chest. Tennis players tend to have strong pectorals and deltoids on their dominant side -- muscles in front of the body -- and a weak rotator cuff, rhomboid and trapezius...
For me the serve is about: forearm, hand, chest and back muscles. The other muscles like your shoulder, bicep, tricep etc. Are all stabalizer muscles so you don't throw your shoulder out or mess up something up. I don't think loose is a good term. Natural is a better. Do you think about walking, or do you just walk?
THE TENNIS SERVE. 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.
Kibler determined that during the tennis serve approximately 51% of kinetic energy was produced in the trunk/legs with the shoulder contributing 13%, elbow 21%, and wrist 15% . HIP AND TRUNK ROTATION. Figures 1c-e highlight the hip and trunk rotation, which represents the next link in the sequence.
