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 eccentric contractions of the shoulder and upper arm rotation in the transverse plane are performed by the anterior deltoid, pectoralis major and subscapularis. Body Systems Used in 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.

Tennis Vocabulary | Vocabulary | EnglishClub (20), this method is accurate to about 5 during arm flexion and 7 during arm abduction when the humeral elevation is below 90100. 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 muscles in the upper back and shoulder blade. The glenohumeral joint center (GH) was also estimated by regression (8,29) in the static recording. 24. 35. In the modern game, we see two types of serves: the foot-up serve (figure 1.9) and the foot-back serve (figure 1.10). Physiother Theory Pract. 1. iis express not working with ip address. Rh was decomposed into a XTZfYh sequence of joint angles appropriate for the tennis serve (1): adduction(+)/abduction() rotation (about the Xt axis of the thorax), flexion(+)/extension() rotation (around the floating Zf axis) and internal(+)/external() rotation (around the Yh axis of the humerus).

Explore another technical piece from Human Kinetics HERE. University of Pennsylvania physics professor Howard Brody has identified two key tactics: Strike the ball as high off the ground as possible or give the ball more topspin, which creates an area of low pressure beneath the ball (a phenomenon known as the Magnus effect) to make it nose-dive into the service court.

A tennis ball's spin barely decreases during flight, and actually increases when the ball hits the court. There is an interplay between eccentric (lengthening) and concentric (shortening) actions that allows the body to store and release energy based on the phase of each stroke. Four important synovial joints - Skeletal system - BBC Bitesize All games of tennis consist of six basic strokes: the serve, forehand groundstroke, backhand groundstroke, forehand volley, backhand volley, and the overhead smash. The tennis serve return is key when attempting to break serve during a tennis match. Finally, if an opponent is deep in his court, a player may suddenly employ an unexpected drop shot, softly tapping the ball just over the net so that the opponent is unable to run in fast enough to retrieve it.

In addition, the values of each humerothoracic and scapulothoracic joint angle were extracted at all key events, and the minimal and maximal angle values for scapulothoracic joint angle during the whole serve were used to compute the amplitude of each scapulothoracic rotation. This is especially important in open-stance backhands, which are becoming more prevalent at all levels of the game. First serves are flashy but second serves are a better predictor of success: The top three players in the world are men who've won the most points on their second serve.

The anterior deltoid, pectoralis major, subscapularis and wrist extensors contract concentrically to rotate the shoulder and upper arm through the transverse plane as the posterior deltoid, infraspinatus, teres minor, trapezius, rhomboids and serratus anterior contract eccentrically. Pros are successful on 50 to 60 percent of their first serves, which are faster and have flatter trajectories than their second, slower serves. Matsui K, Shimada K, Andrew PD. Difference in racket head trajectory and muscle activity between the standard volley and the drop volley in tennis. Introduction When playing Tennis our Body Systems work in different ways to support one another.

Another very common example is the quadriceps muscles at the front of the thigh when landing from a jump. The baseline is where a lot of the modern game occurs.

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). The action of the serratus anterior muscle is crucial to preserve the amount of space under the acromion (12), to limit the anterior and superior translations of the humeral head in the glenoid cavity (3), and to avoid the elongation of the anterior capsular ligaments, in particular the anterior band of the inferior glenohumeral ligament (27).
