The article talks about how jellyfish create areas of low pressure in front of them to pull them forward. I wonder if top human swimmers can do something similar.

Phelps, for example, has an unusual cadence in his freestyle stroke at the end of the 200IM. He takes two strokes and then pauses for a brief period; its like a polska rhythm. Maybe some part of this is creating a void in front of him. Its visible in this video (around 2:03 https://www.youtube.com/watch?v=3cjwuJiwevo)
