No, those are the kayakers that wear a waterproof video camera on their helmets, paddle over the waterfall and create a video like this one:
This video, simply called "Kayaking Over Waterfalls," is from the folks at First Ascent and it features First Ascent athletes Ben Stookesberry and Chris Korbulic.
Here’s a bit more about the them and the video from First Ascent:
Brazil is a nation of water, with a massive geographic area and the largest freshwater supply in the world. The vast, untapped reserve of remote rivers and cascading waterfalls makes some of the best expedition kayaking on the planet. With a rare chance to explore the remote reaches of the Amazon's drainage, Ben and Chris have made a habit out of scouting and running Brazil's vast network of waterfalls and whitewater.Not only does the video show the beauty of Brazil, it offers some incredible adrenaline footage.
