I've only recently come accross the "eccentric exercise" term myself. "Spasmodic" would be a better plain english term and still scientifically describe the concept assessed. I think some of these researchers set out to deliberately make their work unreadable by lay people.

And "stagnant lifestyle"? Judgey? Much! There have been studies that have shown that modern, busy lifestyles are a major contributor to sedentry activity levels.

Still, the positive of this paper should not be diminished - any activity is better than no activity and "pottering about" in a garden or a workshop counts towards a healthy lifestyle. Again, other studies have shown that the short walk to public transport shows a marked improvement in health outcomes, compared to those locked into using private cars for the commute, due to circumstance (no access to transit) or choice.
