Thanks for info guys, I think I will slowly start a search myself.
Trivia, those articles are close, especially “Effects of a yoga program on postural control, mobility, and gait speed in community-living older adults: a pilot study”. Shame its so small and short (8 weeks).
I was thinking about cultural aspect of this problem. My friend from Sri Lanka told me that in most places people would frown if you would start jogging on the street (and consider this as oddity and waste of time). In Australia for example, people would think rather that such person is doing something commendable (that is, physical activity is a value). So I guess due to culture, its easier to exercise and be fit in Australia than in Sri Lanka. Similarly, I’m thinking what aspect of the culture would have to change in order to create some social pressure for elderly people to exercise more (and “pre-elderly” to start serious exercise to prevent age related disabilities). Scientific research would be one thing - recommendations from “health authorities” have some effect (other than TV shows and dramas - if scenes with elderly people would be shot at gym it would have some impact on audience).
Regarding this article about 8 week intervention. It doesn’t seem to have much psychological impact - the fact that after few weeks I could get up 1sec faster than before doesn’t seem so great. I imagine a study that would show that after few years of regular practice, elderly people from intervention group can do things like Mrs Calman (from the link from CityMonk). That would be a great message…
