This is a fair point. I certainly agree with what the article is saying, but the presentation is one-sided. There is no mention of alternative explanations for the decline in ability to self-regulate, or wether standing still is measuring something other than self-regulation. As well, the headline is an accurate condensation of the research findings. It does not tell us the important part of the article, but it does tell us the only part that I am most willing to believe without reading the original study.
