Hey
@coolrunnings,
Apologies for my rant, these studies get me worked up....
I'm sure it's been said before...Don't get caught up in studies.
If you want to pass these courses you need:
1) Proper mental preparation
2) Sensible, steady build up of strength and aerobic capacity over a prolonged period of time (many months and years)
3) Skill acquisition (navigation etc)
These studies are bullsh#t. I have worked with and met plenty of 'special' people who could NOT squat those weights BUT they passed their respective selection courses by doing the basics well and being very mentally robust. You cannot quantify those qualities into a 5 second squat. That's why selections are long and drawn out... to paraphrase a well known book title, "It's not about the squat".
Stay away from scientific studies about success. Listen to real people who have been successful. Do the basics well and you will smash the course.
