Last month at the Winter Nationals, Zane Grothe broke two American records in the 500 and 1650 freestyle: 4:07.2 and 14:18.2. Not a bad weekend! As I watched the video of his swims several times, there were three things about his freestyle technique that he does exceptionally well and that really stand out to me.
I understand Zane majored in Aeronautical Engineering, which by definition makes him smart. At some point in his classes they must have taught him that submarines go much faster under water than on the surface. Zane has figured out that eliminating surface drag in his freestyle at the surge point is a good thing. Of course, it doesn’t hurt that he has a low drag coefficient body shape to go along with getting underwater.
He does this not only with the right arm, coming off of the breath stroke to his right, but also with the non-breath sided left arm. Accelerating his hand hard to the water adds important kinetic energy to the strong pulling arm and kick behind, increasing his propulsion; what we at The Race Club call coupling energy. The fast hand to the water recovery also forces the body to rotate quickly at this pivotal point in the pulling motion, another important coupling motion.
The kicking speed is the baseline speed of a swimmer and Zane has a pretty high baseline speed. Those that can sustain the steady propulsive six beat kick are swimming in a river down stream. Those that cannot, are swimming in a lake. I’d rather be in the river going downstream.
It is not that Zane is the only swimmer using these three important techniques. It is just that he did them better than the other swimmers on that particular weekend. In fact, he regularly executes them all really well and as a result, swims exceptionally fast.
Yours in swimming,
