In what way where the British soldiers unfit for duty in the Boer War?

by ImboundCarp

In the articles that I have read on the Boer war it mentions that 40-60% of British soldiers were found to be physically unfit to fight. What variables where the Medical Army Corps evaluating when they produced these statistics?

Are these articles saying that men already in the Army were unfit to fight, or that recruits were unfit for the Army? There is much talk of a recruiting crisis among Victorian Britons, but I have not heard of a crisis within the Army among existing soldiers.
