It is perfectly reasonable for the control group to be following standard guidelines. In all medical trials, for example, the control group usually follows the current standard of care. Why does that stick out?
- pmiller2 6y agoMedical trials are generally placebo controlled, if they're any good.
- ksdale 6y agoIt sticks out at least in the US because "following standard guidelines" is not what most people do. Most people (at least in the US) hardly exercise at all, so a control groups that exercises 30 minutes a day is already a group that exercises a lot compared to the average person. I agree with you that its reasonable, but the study then teaches you about the relative merits of different kinds of exercise, rather than the effect of exercise compared to "no exercise" which is how people tend to think of a control group.
- solveit 6y agoYes, but I think the question motivating the study is "should we change standard guidelines?" and not "is exercise good?". Not least because exercise is very very good and rechecking that isn't a very high priority.
