This is a slide from the presentation „New ways in coaching tennis and other sports“ by Frercks Hartwig.
Aus der Präsentation „Neue Wege im Training….“ von Frercks Hartwig, TMS Coaching
Following the principles of differential learning and the constraints led approach, we can change the constraints without repeating them the next practice. Regular variation without repetition and the trust in new studies about motor learning gives the coaches and the players more than a handful of various drills. This one is about changing constraints by starting from unusual points in the tennis field. This requires adaptation to all players and opens doors to new solutions of game situations.
Playing the game with rules outside the rules brings players in a situation where they have to solve problems outside the manifested behaviour. We can manipulate court size, rules, time, counting, context of the game and other settings surrounding the game. This improves tactics and skills. In this double drill players have to adapt the direction of the service, the return in a double, the netplay and particularly in the teamwork collusion between server and netplayer.
Another Inner Coaching drill, using differencial learning and constraints led approach to develop tactics and necessary skills.
Interview in der Südwest-Presse mit TMS Coach Frercks Hartwig über Neue Wege im Tennistraining.
This is from Nick Jacques Tennis. Nice ideas for a constraints led approach (CLA). This already shows the difference between CLA and differential learning (DL). In the CLA the intention and the plan for the development of the skills is an idea of the coach („avoiding backswing“). In a DL approach the coach also offers different situations (like those in this video). But the solution is in the responsibility of the player, not in the responsibility of the coach!
Both approaches are implicit, but there is an important difference in the attitude to the learning athlet. While the coach in the CLA drill has a goal (backswing), the DL coach knows and intends nothing. The system „player“ is a black box and there is no expectation in the long term development of individual skills. The examples in Nicks CLA are in DL only one possible solution for the motion and will not be repeated.
Thx to Nick for the nice ideas 😀. I love his quote: „I have no influence over this as I am still with very little noise from me.“
“ 3 constraint led approach drills that have helped reduce the size of my students take back. Lillian has previously been taught a large loop on her take back which has isolated her upper body from her lower body, making it very hard for her to adapt to the many different balls she would need to cope with in a match situation. Lillian has made great improvements on her coordination, here are a few key exercises that have helped her progress. Note how Lillian is intrinsically motivated as the exercises engages her and draws out the effort, you can see I have no influence over this as I am still with very little noise from me 🤗 „
Differential learning (DL) and developing of grundstrokes by changing variations. Player starts from balance pad with fast steps on pad. The coach feeds balls out of the basket. Player plays the ball with the forehand crosscourt.
The essential of DL is to varify tasks and situations. One situation is only used in one training, In the next one, we set new .
- hanging the position of the pad
- different tasks on the pad (on one leg, with the back to the coach, standing sidewards,…)
- changing the position of the pad
- changing ballfeed (in the video the coach throws the ball over (!) the baseline
- changing target (longline, cross, long, short, with spin, small target, finishing the point with an opponent,…)
- different pads
This drill additionally develops the proprioceptive awareness.
