It does support my claims - but that was not the purpose of the study so you'll actually have to read beyond the abstract to see it

>Also, professional athletes do both high rep and low rep weight training. The high rep build the strength but the low rep build the endurance to use the strength.

I agree - which is why I don't believe that heavy weightlifting is detrimental to one's ability to do multi-hour hikes.
