1) at seconds 8-10, note the head height take back. The drop at seconds 10-11 initiates the power in the swing
2) freeze around seconds 9-10 and you see a closed stance, with the shoulder/torso/hips in line with the intended direction of the ball. Even if you go to a more open stance with the hips, you still want to line up the shoulders
2a) freeze after the swing at 15/16 seconds and you see her hips are parellel to the baseline, meaning that she made a 90 degree hip rotation. also note that the butt of the racquet/left elbow is pointed to the intended target after contact, indicating a 180 degree shoulder rotation from the stroke.
3) Note at second 10, left foot is in the air and at second 12 the right foot is in the air, indicating a full weight shift
4) ***Note that at around second 11, the hips rotate/open toward the net while the racquet stays back - this is similar to professional golf and baseball swings. This motion is key to the kinetic chain and stretches the muscles in the arm to make the ensuing swing more powerful***
5) freeze at 13 and note the extension of the left arm after contact, meaning she has pushed through the shot and brushed up the back - this is where a lot of power is lost in rec players who stop swing forward after contact and cut right to the finish over the shoulder. I like the think of pushing and not swinging with the left arm更多精彩文章及讨论，请光临枫下论坛 rolia.net
