Noch ein Nachtrag zum Armzug:

3. Reinforcement of Pull Path
Since the original edition of Swim Speed Secrets was published six years ago, an ideology that began in the early 2000s has grown in popularity—the “pull straight back” craze. I’ve watched with uneasiness as coaches and swimmers revile the S Pull to such an extent that they’ve swung the pendulum too far in the other direction. The newly chosen semantics imply that swimmers should eliminate all movement on the lateral and vertical dimensions of our three-dimensional sport. The result? Shoulder injuries are skyrocketing, and swimmers who use this path are not getting faster. While some progress has been made toward convincing athletes of the curvilinear path, the straight-back path is still too readily taught. This edition includes a section intended to redirect the pendulum, along with photos throughout of the most current freestyle Olympic medalists from Rio 2016, confirming the curvilinear path in their strokes.

Evtl. auch interessant aber ausführlicher: lets-talk-about-the-s-pull-in-swimming/

Mein Fazit: der gerade Pull ist theoretisch schon optimal, zur Verletzungsprofelaxe sollte er aber doch etwas kurviger ausfallen.
