Is he on PEDs or what? ...
I've got Rafa ML 2 units and Rafa 3-0 1 unit... I believe he will loose at least one set.

Humidity in Australia is pretty bad and it's warm even at night.

Remember it's the middle of summer in Australia.

Nadal probably took some caffeine pills... Is that legal in this tournament??? I would say negative on the PEDs, as most actually kill your cardio. Contrary to my other posts where I was talking out of my ass a bit, I think nadals clean. Maybe a history of high blood pressure in his family, that would make him sweat... Also if he's very nervous, that accelerates your heart rate as well

Conditions, adrenaline, blood pressure.

Nadal is an extremely nervous player
Anyone who read his book 'my story' knows the guy is insecure as hell, that makes his achievements even more astonishing

It depends of their genes.

Most players that have Injurys also sweat a lot because there body is under a ton of stress. Nadal alone is probably stressed/nervous in a match he has to win. Obviously his career may be cut a bit shorter than most because of this. Genes also have a ton to do with this as stated above. Since Nadal wins a lot, I'm sure he's tested more than most athletes. Although I have no evidence of this.

Tennis players barely get tested at all - their system is a joke and very easily evaded.
