The upper body rotates to the right, shifting the body weight onto the left foot, while the club is guided backwards in a flat upper arc in a loop. The club is swung down in a small arc and then swung parallel to the hip axis with increasing acceleration relatively flat forward upwards towards the incoming ball. The optimal point of contact is in front of the left hip ... Only shortly before the point of contact and especially after it does it follow the arm movement and turn into the frontal position, which enables the arm to swing the club for a long time in the direction of impact when pulling through. Then the racket is swung naturally to the left shoulder " (DTB 1975)

  8. 8. www.innercoaching-blog.de 8 "Characteristics of the main action within the striking phase: The club is swung forwards, slightly upwards, so that the ball gets a little forward spin. The racket is accelerated to achieve the desired ball speed. The club is swung far in the direction of the shot for greater accuracy and safety. The ball is hit at a suitable lateral distance and in front of the body with a vertical striking surface in order to achieve optimal energy transfer. Immediately before the meeting, the wrist is brought into a position corresponding to the take-off speed in order to achieve the highest possible accuracy. At the meeting point, the grip is strengthened and the wrist is fixed very briefly ... " (DTB 1995)

And not only in tennis, but also in the other racket or return games, as the curricula of that time show. " DTB 2020

  20. 20. www.innercoaching-blog.de 21 „Once the ball is in motion, it comes at you in an infinite number of angles and speeds; sometimes with more topspin or backspin, sometimes flatter, sometimes higher. The difference may be small, microscopic, but the variations that your body makes - shoulders, elbows, wrists, hips, ankles, knees - are exactly the same in every stroke. "(Rafael Nadal)

This is crucial for motor and cognitive learning" Daniel Memmert, Professor at the Sports Institute for Training Science and Sports Informatics, Cologne
  33. 33. www.innercoaching-blog.de 34 “By now every learning psychologist knows that stubborn repetition of one and the same sequence of movements doesn't really get you any further. In basketball there were two test groups: one threw 5000 times from the same spot, the other 5000 times from a slightly different position. And now guess which group has demonstrably improved by 20 to 30 percent? We think less of repetitive learning of the same situation over and over again. " Ralf Rangnick, soccer coach
