1). Baseball Swing (r) Sh. Drops L Sh. Elevates Arms extend forward Hips turn towards pitcher ((r) =Medial/ L= Lateral) During the baseball swing, the batter 1st chooses his batting stance. Upon the swing, he rotates his trunk and hips towards the pitcher. His head follows the direction of the ball, resulting in the (r) rotation of his neck. His (r) and left arm will extend as he swings the bat (in this case, the batter is right-handed), while his left shoulder stays closely to his body. His (r) shoulder will depress and pronate, and his left shoulder will elevate and retract to accept the force of the swing. The batter will push off with his rear leg ((r) foot doing eversion), while his left foot plantar flexes to sustain balance during this forceful period of weight transfer. The main objective of the batter is to keep his eyes on the ball, and to make a clean-smooth transfer of his body weight. ...read more.


Therefore, the back begins to arc trying to begin the performance, and compensate for the change in center of gravity...beginning the 1st phase of the back - flip. 3). Volleyball Serve The volleyball serve uses a forceful propellant of the body's serving arm, rotation of trunk, and the rotation of its hips. As your head extends to watch the ball, you thrust your serving arm forward (pronating your shoulder girdle), striking the ball at about 1 o'clock in front of your body. Your trunk will rotate left, and flex forcing the ball forward. As you slightly push off the ground (plantar flexing your left foot), you will rotate your hips in the desired direction of the attack. For a more successful and forceful attack, the server will thrust their body weight forward (like the baseball swing). With the help of rotating your hips and trunk, the ball will be struck with more power and accuracy. ...read more.


5). Shot - Put Toss L Sh. (r) Sh. Elevates Depresses The shot - put toss is a sport where you toss of weighted ball as far as you can. As you start off with the ball curled under your chin, you steady your stance (center of gravity) in preparation for the toss. Similar to the other sports skills, there is a transfer in body weight that will help project the ball. While the performers body weight transfers, his trunk will flex forward, while he extends his knees and hips. In addition, the performer is going to push off the ground while he plantar flexes with his feet to add to such a thrust. The performer's throwing arm ((r) shoulder/shoulder girdle) will elevate and pronate, while his other arm will depress and retract. Along with the extension of his throwing elbow, the clean/smooth transfer of weight and these particularly desired motions, the weighted ball will travel quit far. Finally, just like the baseball swing, the performer is rotating his hips toward the desired target allowing a more forceful combination of energy when releasing the ball. ...read more.
