First of all it makes a difference as to which of the overlapping circles contain which numbers. for example, is the 15 inside the overlap of all three circles? is the 38 in the overlap of the walk and stretch circles?
I made some assumptions - since you didn't tell us.
in this case there were a total of 205 people in the study?
Second, you really didn't tell us what you want to have answered or explained?
but here are some possible answers:
141 adults walked.
64 ran and
106 stretched
That's the total number of people in each of the circles including all the various intersections.
