Strange Plant from the Jungle?

Was watching a programme a few weeks back in England. The guy was in some jungle, i think the Amazon. He claimed that this plant he picked and ate was called ‘the strongman’.

I do not quite catch the indigenous name but what really caught my intention was the claims of this explorer. He said this plant when eaten reduced lactic acid build up and increased muscle strength and endurance.

Now i want to know what it’s called and how to get a hold of it without taking a trip to the amazon which i nearly did. Literally.

He ate the stalk and said the tribes people did this. It was green and fairly tall and thin.

Could someone help me in my research.
