It is certainly not statistically significant, but at least when we look at the data, there is certainly not statistically significant. What I think is more interesting, though, is actually the intensity of the activity that they're engaged in. So one of the things that does seem to differ between their populations and our populations is the fact that actually they do spend some of their day involved in very high intensity activity. So when you look at the distribution of the vigorousness or the difficulty or how hard the activity they're actually engaged in, y ddwy ni gynnytio gwaith am wrth denidire caused o'r ddycan frase.

Occasionally they would involve themselves in short bursts of sprinting, particularly when hunting or foraging. But I mean 1.5 to three kilometers an hour, that's a really slow stroll, that's not even kind of average walking speed for most populations nowadays. That's taken it pretty easy. I mean even when you look at the studies on persistence hunting, the average speed at which they move at is 6.1 kilometers an hour. Now that's a bit of a route march but that's not a jog, that's still walking just at a pretty quick pace. But what it indicates is that they were probably involved in some high intensity activity and then a lot of low intensity or sedentary type activity. And even in children as well, we see that in the child populations they spend a lot of time engaged in very low intensity activity and then occasionally very high intensity activity. And this is what I think might be missing from what most modern populations are engaged in. So what about the types and modalities of exercise that they're engaged in? So we know that we're doing high intensity activity but what types of activity were they engaged in to produce that high intensity? So most of us think about the idea of a hunter-gatherer and again coming back to this idea that most in the kind of paleo-fitness sphere we recommend play, primal play, all these kinds of things, very unstructured social type physical activity. Studies that have looked at hunter-gatherer populations do indicate that they do engage in a lot of play but not play as we would think about it or certainly not play as in is recommended from these paleo-fitness guys. So when you look at play you tend to see that the children engage in a lot of physical activity type play, running around the playground, the types of things you see kids doing in the school yard, playground, school yard, doing it again, Americanisms. But when you look at the adults the play they engage in is more sat around, chatting, cracking jokes, playing pranks, being creative. It's not physical activity play, it's play in spirit. So do we necessarily need to be structuring exercise around this concept of play when even hunter-gatherers own adult physical activity patterns aren't structured around this idea of well unstructured play activity? Now as I said they did engage in a lot of random walking patterns but what we typically see is most of that occurs around the camp, some of it occurs when they go out foraging or hunting but most of it occurs around the home for use of a better word. Now out of interest I've actually been using a pedometer myself recently and it's interesting the number of steps I actually take just walking around the house each day. Sometimes before I leave for work I sometimes accrue 2,000 steps just from walking room to room, picking things up into the kitchen, make a coffee, into the bathroom, brush my teeth, whatever. We do spend a lot of time walking around the house and that's typically where we accrue most of our walking type physical activity. It's surprising how much we actually accrue and the same applies for hunter-gatherers as well. Most of their walking is just around the camp, around the campsite, around the huts, so on and so forth. Running, did they run? Well we've got some evidence of persistence hunting but then we've got other populations where the researchers have never seen a single person in the tribe running. So it's difficult to say we should be running, maybe we should, I don't know, we can but should we be doing it? I mean if hunter-gatherers don't do it if they don't need to should we be going out and racking up miles and miles around the block each day?
