I'm a fairly active person, by nature, and I have a few golden rules I follow, like parking at the far end of the supermarket carpark (fewer paint dings is an added bonus), walking all the isles, when when I don't need anything in them, and aside from overnight, I use the loo upstairs, if I'm downstairs (and vice versa). So I'm active but also what I call sedentary active.
On Wednesday our local DUK group meeting had a speaker from the NIHR, talking about exercise, relating it to both diabetes and general health. He was excellent, and made his talk interactive. I don't mean we were doing star jumps or running on the spot, but making contributions and comment along the way.
Aside from "the more you can move around and exercise the better" generalisations, he shared a couple of absolute humdingers. The shocker for me was that studies have shown folks significantly overestimate their activity levels, but again, studies show the average person is sedentary 80% of the day. A day being a 24 hour cycle.
The second, and most amazing thing was they ran a small study (most likely a feasibilty to something bigger) into the impacts of just standing up. This is the act of standing, not the act of loitering around. Their study had participants into their lab for 2, 8-hour periods. During the first, the participants were fed a couple of set meals, and their body data (pulse etc) monitored by FitBit stylee kit, plus regular bloods (via a canula fitted at the outset).
The process was then repeated (participants, food intake, content, timing and measuring) exactly, except that participants were asked to stand up and stay standing for a 5 minute period, every 30 minutes. The improvement in their blood glucose scores was positively significant. He quoted a figure, but when I interrogated him (as I would,......... ahem), he did admit he'd have to revisit that detail.
So in effect, limiting the duration of our sitting to shorter periods of time is helpful, even if we can't do anything else.
There's about to be a feasibilty study run to look at the impact of exercise (no dietary interventions) on pre-diabetic individuals. Those measurements will be done by FitBit gizmos and participants wearing Libre sensors.
There is some fascinating work being done on diabetes at the moment, and that's only a tiny, tiny granule of it. The NIHR site details all the various studies and trials they are running, and they're always looking for trialists.
