The acceleration phase of the upper arm is performed through concentric contractions of the infraspinatus, teres minor, posterior deltoid and trapezius. During the follow-through phase, the scapula internally and downwardly rotated, and posteriorly tilted, while the upper limb lowered and crossed the players body. Andrew DP, Chow JW, Knudson DV, Tillman MD. Body systems used in tennis by Cameron Campisi. Scapular positioning in athletes. [4] Another seldom used shot is a behind-the-back shot, which, as its name suggests, is hit by crossing the preferred arm across his/her back without swinging. During the backswing of the one-handed backhand (Figure 1.6a), the gastrocnemius, soleus, quadriceps, gluteals and hip rotators contract eccentrically to load the legs and begin the hip rotation.

Pre- and post-impact muscle activation in the tennis volley: effects of ball speed, ball size and side of the body. To broaden our understanding of muscle function during the tennis volley under different ball placement and speed conditions by examining the activity of selected superficial muscles of the stroking arm and shoulder (flexor carpi radialis, extensor carpi radialis, triceps brachii, deltoids, and pectoralis major) and muscles related to postural support (left and right external oblique, lumbar erector spinae, and gastrocnemius) during the volley. If a player does swing through on this type of volley it is very difficult to control and will more often than not go out of the court. Carpals (Wrist): To flick and move the racquet. 2.2. Step 3: The Preparation. As the ball rockets off the strings, it must travel within a very narrow range of angles to both clear the net and bounce inside the service box. During the backswing of the forehand groundstroke (Figure 1.5a), the gastrocnemius, soleus, quadriceps, gluteals and hip rotators contract eccentrically to load the lower legs and begin the hip rotation. Then, the transformations from the static position to the dynamic positions were computed (35) using the markercluster (AC, AA, and SS). Please enable scripts and reload this page. It is initiated by tossing the ball into the air over the server's head and hitting it when the arm is fully stretched out (usually near the apex of its trajectory) into the diagonally opposite service box without touching the net. The results revealed that, during the cocking phase, the scapula externally rotated and posteriorly tilted to attain the maximal humeral external rotation.

Three-dimensional scapular kinematics during the throwing motion. When a game reaches deuce the player must then win by two clear points. During the acceleration phase of the tennis serve, the humerus abducted to achieve its maximal elevation, while the humerus abruptly internally rotated. Similarly, Rs was decomposed into a YTXfZs sequence according to ISB recommendations (36): internal(+)/external() rotation (about the superior axis of thorax YT), downward(+)/upward() rotation (about the floating axis Xf), and posterior(+)/anterior() tilt (about the mediallateral axis of scapula Zs) (Fig. We've updated our privacy policy. A previous study has shown that the humeral internal rotation alone is accompanied by scapular downward rotation and anterior tilt (25).

The Serve Instead of the fastest serve in the world, Andy Roddick's serve (which we will address later), we have chosen to analyze the standard serve (see Elliott et al., 1995), what happens to be Roger Federer's serve, which is also similar to Novak okovi's serve. [4] Forward-facing between-the-legs shots are also occasionally employed; they are sometimes called "front tweeners".[5]. The mean CMC values for the scapulothoracic joint angle patterns were 0.98 0.01 for internal rotation (range = 0.950.99), 0.97 0.03 for upward rotation (range = 0.910.99), and 0.95 0.03 for anterior tilt (range = 0.870.98). There are, however, things that the server can do (short of hitting the ball slower) to increase the size of the acceptance window.

From a strategy and tactics perspective, the main keys to a successful serve are pace, spin, and placement. This maximal humeral external rotation is generated by the concentric action of the infraspinatus and teres minor muscles. No player displayed a maximal abduction of the humerothoracic joint above 120 at any time of the serve. This volley is used on both the forehand and backhand side and involves players punching through the ball. Highlight selected keywords in the article text. eCollection 2021.

"Players just can't pick it up.". Finally, during the follow-through phase, the humerus adducted, flexed and internally rotated, when the scapula rotated internally, downwardly, and tilted posteriorly. Exploding upward toward the ball, pro players employ extraordinary timing to efficiently transfer forces from the legs, through the body segments, to the striking hand in what biomechanists call "the kinetic chain principle." The slice serve can be used to go for an ace, to push the receiver off court and out of position, or to make the ball bounce up at the receiver's body. We may earn commission if you buy from a link.
