A hollow medullary cavity is found in the center of long bones and serves as a storage area for bone marrow. The amount of anterior tilt remained similar during the early cocking phase, decreased during the late cocking phase, then increased during the acceleration phase, and finally decreased after impact (Table 1). The shoulder and upper arm on the dominant side rotate through the transverse plane through concentric contractions of the anterior deltoid, pectoralis major, subscapularis and wrist extensors, and eccentric contractions of the posterior deltoid, infraspinatus, teres minor, trapezius, rhomboids and serratus anterior. [3][4] The shot was pioneered in the 1970s by Guillermo Vilas and Yannick Noah, both of whom claimed to have invented it; later players to use it include Ilie Nstase, Boris Becker, Gabriela Sabatini (whose version was called the "Sabatwini"), Andre Agassi, Roger Federer, Rafael Nadal, Novak Djokovic and Nicholas Kyrgios who helped popularize the shot. The backhand is struck from the non-dominant side of the body by bringing the racquet across the body (showing the back of your hand to the opponent) and swinging the racquet away from one's body in the direction of where the player wants the ball to go.

Also known as the between-the-legs shot or the Gran Willy (after Guillermo Vilas, an early pioneer), it is generally performed when the player must run to recover a lob and has no time to turn back to face the net before attempting their return. 2007 Mar 1;6(1):98-105. eCollection 2007.

The tennis serve motion has been mostly described through the motion of the upper arm relative to the thorax. A new formulation of the coefficient of multiple correlation to assess the similarity of waveforms measured synchronously by different motion analysis protocols. This motion is very natural to the . During the acceleration phase, the scapula would upwardly rotate and anteriorly tilt, while after impact, the scapula would internally and downwardly rotate in association with posterior tilting. A serve (or, more formally, a service) in tennis is a shot to start a point. laterally across the string plane, gathering spin. When your forearm moves toward your body by bending at your elbow, it's called elbow flexion. Because of these changes, forehand and backhand swings have changed as well.

[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. Transverse fractures.

The best servers combine all three components. The aim of this study was to describe the scapulothoracic kinematics during the tennis serve in highly skilled tennis players while evaluating the repeatability of the scapular patterns. Because of the site of their origin on the scapula, they concomitantly exert a scapular internal rotation motion (5), which demands the contribution of the middle trapezius and rhomboid muscles to stabilize the scapula in external rotation. The scapula is an efficient link to transfer the forces from legs and trunk to the upper limb while providing a stable base for muscle activation and a moving platform to maintain the congruence of the humeral head into the glenoid cavity (15). modify the keyword list to augment your search.

Rotation sequence is an important factor in. Every bone in the body is used during a tennis serve. Kick Serve. Unauthorized use of these marks is strictly prohibited. The concentric contractions of the trunk rotation phase involve the ipsilateral internal oblique and contralateral external oblique, while the eccentric contractions pull in the contralateral internal oblique, ipsilateral external oblique, abdominals and erector spinae. A down-the-line shot is one that is hit more or less parallel to, and near to, one of the sidelines, so that it never crosses the centerline. As the toss goes up, players press their feet against the court, using ground reaction forces to build up elastic potential energy--rotations of the legs, hips, trunk and shoulders that produce maximum angular momentum. Repeatability of kinematic, kinetic, and electromyographic data in normal adult gait. It also protects our vital organs such as our lungs and is the point of attachment for our muscles. Purpose: The raw 3D trajectories of all markers, including the frame of impact, were smoothed using two successive passes of a 20-point sliding average window, resulting in a triangular filter kernel (7). Muscles Used in The Tennis Serve - AthleticQuickness Although the two-handed backhand uses many of the same muscle groups as the one-handed backhand, the two-handed backhand requires greater trunk rotation. During the acceleration phase, the humerus abducted, slightly flexed and internally rotated, when the scapula increased its internal and upward rotation, while anteriorly tilting. In the foot-up serve, the rear foot typically starts in the same position as for the foot-back serve. (17), the scapular posterior tilt is generated by both active muscle contractions and passive structural restraints of the glenohumeral joint during the late cocking phase. Methods for measuring and representing automobile occupant posture. Highlight selected keywords in the article text. Bone Fractures: Types, Symptoms & Treatment - Cleveland Clinic The site is secure. Chow JW, Carlton LG, Chae WS, Shim JH, Lim YT, Kuenster AF.

Bruce Elliott, a professor at the University of Western Australia, has extrapolated the contributions of the body segments to racket-head speed (shown here) using 3D videography and computer analysis. During the forward swing (Figure 1.7b), concentric and eccentric contractions of the gastrocnemius, soleus, quadriceps, gluteals and hip rotators drive the lower body and hip rotation. The soft tissue artifacts remain a major limitation when using skin markers to describe the scapulothoracic kinematics that can be minimized with markers located on the acromion (24).

Enjoy access to millions of ebooks, audiobooks, magazines, and more from Scribd. Table 1. 25. Linear momentum is a product of both mass and velocity and can be generated in both a vertical and horizontal direction. On the non-dominant side, concentric contractions of the middle and posterior deltoid, latissimus dorsi, infraspinatus, teres minor and wrist extensors create the rotation of the shoulder and upper arm, assisted by eccentric contractions of the anterior deltoid, pectoralis major and subscapularis. Movement Analysis of the Tennis Serve with Emphasis on Hip a Such humeral abduction falls within the range of values for which subacromial impingement is susceptible to occur (26), thereby placing the tennis players shoulder at high risk for rotator cuff tendon pain and injury (6). 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. A player will hit the ball with a racquet so it will fall into the diagonally opposite service box without being stopped by the net. Three markers were glued on the racket frame, and retroreflective tape was stuck on the ball to detect impact. If the humerothoracic abduction was above the threshold of 120 (2,34), all the serves from this player were cancelled for the subsequent analysis. The acceleration phase (phase 3) began at MER and lasted to ball impact. Typically, the player chooses which serve to use based on personal preference and style. The sidespin makes the ball curve to the left and dip slightly, then bounce off the ground in a leftward direction (or rightward if the server is a lefty). A small number of players, notably Monica Seles, use two hands on both the backhand and forehand sides.
