Supertraining

Nick, yes I subscribe to Science of Sport blog. Heavy duty reading.

What interests me in this latest Marino study is that the body mass 
differences are so wide between black and white athletes -- 59kg to 
77kg that one would expect heat dissipation differences. 

77kg would be heavy for most marathoners (or even 10k specialists).

[At 182cms (6'1"), I was only 69 kgs (152) at my best in marathons 
and that was not unusual. I started running with a mate and we both 
lost about 6 kg from being fit for team sport (hockey). The thinner 
we got, the faster we got!]

I suspect that weight for weight, east African black runners still 
have an advantage beyond heat dissipation. It could be some other 
genetic advantage of course, but they don't seem to need weights to 
build that sort of extraordinary running strength. But maybe other 
do. I'm skeptical but open.

Go the Waratahs!
