Crawl Hip-Driven

Stile Libero Hip Driven

Lo Stile Libero Hip Driven, utilizzato da Ian Thorpe, Grant Hackett, Eric Vendt, Larsen Jensen, Kaitlin Sandeno, Libby Trickett (Lenton), è un Crawl con una bassa frequenza di bracciata (circa 60-70 bracciate al minuto), la mano si “ferma” davanti dopo l’entrata in acqua prima di iniziare il movimento propulsivo in direzione posteriore. Il più grande vantaggio della tecnica Hip Driven è che il ciclo di trazione più lento permette al nuotatore di realizzare una maggiore rotazione delle anche generando, di conseguenza, una maggiore forza in direzione opposta con la quale spingersi in avanti. Il risultato è una maggiore distanza percorsa con ogni bracciata.

Sebbene questa tecnica possa generare maggiore potenza con la singola bracciata, per essere davvero veloci è necessario utilizzare questa tecnica con ciclo di battuta di gambe a 6 colpi.
