It does. However, it shows even more what is wrong with the media's reporting of science.
From the article we get the title,
"Light Weights Are Just as Good for Building Muscle, Getting Stronger, Researchers Find"
and then text which contradicts the title,
"the group that used heavier weights for three sets developed a bit more strength."
It's fairly common for journalists to fuck up by not reading or understanding the paper they're reporting on, and thus publish conclusions contradicting that paper. It's less common for the title of the journalist's article to contradict its own text. I mean, that's truly sloppy.
Anyway, we can say that lifting lighter weights for more reps is just as good as lifting heavier weights for fewer reps... unless you want to get stronger. Without doing a study, I feel sure that we could say walking is just as good as running, unless you want to get fitter.
If you want to get better at lifting heavy things, you should practice lifting heavy things. Now, will someone give me a PhD?
