Is there anything exercise science has taught me that hasn't been completely or at least partially wrong?
I don't think so...of course this gist of the "rule" is a good one..but even 10% doesn't always work..or sometimes more than 10% is ok...
From the article:
Half the participants were assigned to a training program that increased their running time by 10 percent a week over 11 weeks, ending at 90 minutes a week. The others had an eight-week program that ended at 95 minutes a week. Everyone warmed up before each run by walking for five minutes. And everyone ran just three days a week.
And the results? The two groups had the same injury rate — about 1 in 5 runners.
Maybe, the investigators thought, they might prevent injuries with a conditioning program before the training started. So they did another clinical trial, randomly assigning one group of novice runners to a four-week program of walking, hopping and jumping rope before starting the running program. The others started right in with running.
The conditioning program had no effect. Once again, about 1 in 5 runners in both groups wound up with injuries.
