Of course it does, but ANYONE can eat a shit load of food.
As for being young, interesting point.
What I've noticed is when I was young, we all had manual jobs, no computers and shit like that.
Over 80% of my clients sit on their ass all day in an office.
The majority of the footballers have trades, they are on the tools. They appear to be recovering.
I suppose only time will tell. Either the Frankston Dolphins improve on the football field, or they dont.
No one will give a rats ass if they can squat 140kg if they dont improve.
It would be almost impossible for them not to improve wouldn't it?
As for being young. At 19 I went from 70 odd kg to 80 odd in a year from nothing more than 3 meals per day and Army PT 5 days per week (mainly circuits, some pack marching, a fair bit of running). I wasn't even trying to gain and never ate past being satisfied. Add to that being drunk 3 nights of the week... I did have a thing for drinking 1L bottles of Breaka chocolate milk at the time, maybe that had something to do with it.
I'm sure age plays a big part in how fast you can get strong and how quick you recover (especially if my hang overs are anything to go by).
All this talk of food has got me hungry again...
