The square- and closed-stance forehands require less rotation at the core, and ball contact is made more in front of the player and closer to the net. How Does the Scapula Move during the Tennis Serve? Most commonly used is a forehand drive serve. HHS Vulnerability Disclosure, Help However, the study of Senk and Chze (34) shows errors under 11 in internal/external, upward/downward, rotation and anterior/posterior tilts for quasi-static movements of arm elevation below 120 and for horizontal flexion. During the early cocking phase, the humerus abducted, extended and began its external rotation, while the scapula mainly externally rotated. Anatomical Description of Tennis Shots 2.2.1.

However, few data on the asymptomatic scapular motion relative to the thorax during the overhead motion under real conditions are available. This site needs JavaScript to work properly. The "tweener" is a rarely used shot in which a player hits the ball between his/her legs, generally with their back facing the net. Linear momentum is a product of both mass and velocity and can be generated in both a vertical and horizontal direction. Considering the window from two frames before impact to two frames after impact, the mean differences in scapulothoracic angle values computed based on the raw 3D trajectories and smoothed 3D trajectories of the markers were 1.68 1.28 for internal(+)/external() rotation, 0.98 0.73 for downward(+)/upward() rotation, and 1.45 1.69 for posterior(+)/anterior() tilt. A slice serve is used in order to gain an advantage via the unpredictability of a spinning balls bounce. During the tennis serve, the scapular internal rotation decreased during the early cocking phase, remained similar during the late cocking phase, then increased during the acceleration phase, and until the completion of the serve (Table 1). During the backswing (Figure 1.7a), the eccentric contractions of the gastrocnemius, soleus, quadriceps, gluteals and hip rotators load the legs and begin the hip rotation.

The average 2400-rpm spin rate Yandell has observed in Roddick's 130-mph serves doubles after the ball hits the court's surface--to a whopping 4800 rpm. Concentric and eccentric contractions of the obliques, back extensors and erector spinae cause the trunk to rotate. The muscles in the upper back and back of the shoulder act concentrically (shorten) in the loading phase and eccentrically (lengthen) in the follow-through. to do military or naval service. Each tennis player stands on opposite sides of the net and uses a tennis racket to hit the ball back and forth.

In particular, the twisting motion of the arm or pronation is necessary to achieve a powerful serve, and pronation in tennis is used to produce more ball spin. The cocking phase was split into the early cocking (phase 1), corresponding to the first 75% duration of the cocking phase, and the late cocking (phase 2), corresponding to the last 25% remaining (28,32). The follow-through phase (phase 4) represented the final phase, from ball impact to the minimal height of the tennis racket. The acceleration phase is when you release the energy through the end of ball contact. Solano Verde Water District. Write CSS OR LESS and hit save.

It helps to make tissues strong and resilient, able to withstand stretching. 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. However, the roles of the deltoid muscles during a volley cannot be determined without knowing the actions of the other shoulder joint muscles. A passing shot is a groundstroke that is hit out of reach of an opponent at the net far to his left or right. The serve speeds you see on courtside digital displays are measured just as the ball leaves the racquet. Next, you're going to want to toss the ball using your full trophy pose. In eccentric motion, tension increases on the muscle as it lengthens. Strength and flexibility, particularly of the muscles of the upper back and back of the shoulders, are key. Step #1: Position yourself and set your stance. 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. government site.
