That abstract is hardly damning evidence against weightlifting. I mean, all it really says is that the performance gains between lifting and riding over a 10-week period are equal. It does nothing to say that lifting doesn't belong in a periodized training program.

And, as others have already alluded to, the study as designed didn't even look at the areas where weight training would be expected to have the greatest benefit, i.e. 5sec and 1min power.

So really, it's an answer to the wrong question. Patentcad, I'll translate: this study is basically a throwaway.
