Around 1992, while stationed at Bitburg Air Base, Germany....my squadron appointed me as one of the fitness-test-gurus (3 of us). This was the year, they went to bike-testing.
So the three of us go over to the base gym, and 'Larry', the 'guru of gurus' was set to train use for about 90 minutes.
The training game is to orientate us....then we (two testers) would test the 3rd member of the group.
First guy up....'Kenny'.....a 1.5-pack a day smoker. I'd offer the opinion that he was average in-shape, and after the initial pump-up (maybe 2 minutes)....we started the test, and in roughly seven minutes...wrapped it up. 'Kenny' passed.
I came up....non-smoker....better than average shape. Same story....2 minutes of build-up and in seven to eight minutes....I passed.
Then 'Wanda' comes up. She was a 20-mile a week runner....zero fat....she did a half-marathon every other month.
We did the initial 'pump-up' with the bike.....probably four times. Then we stopped and readjusted all the numbers possible with the stupid bike. We could not get her heart-rate up to what the test required.
'Larry' did pulled out a cheat-sheet....which basically said something like 8-percent of all Air Forces folks could not pass the bike test because they were in over-the-top condition. So we adjusted the bike values to the harshest level possible....it took maybe four minutes, but we finally got the heart-rate up and started the test. She marginally passed the test....but by 'Larry' and his cheat-method.....she passed.
A crappy test method? I probably tested 40 folks the next six weeks.....with four of them in this situation.
Most everyone who tested via the bike...felt it was a failure.
It was one of the ten times that I felt the Air Force did crappy planning and knew the change was crap, but still proceeded on.
