Studies suggest that exercise literature tends to be very difficult to
read and the writing not matched to the reading ability of the audien
ce for which it was intended. Two studies aimed at describing the read
ability and comprehensibility of the recently developed U.S. Centers f
or Disease Control and American College of Sports Medicine ''Exercise
Lite'' brochure were conducted. In Study 1, the brochure's readability
was assessed using four different formulas. This study showed that th
e brochure was written at a level equivalent to that of a scientific j
ournal article. In Study 2, 56 participants (two-thirds of whom were c
ollege graduates) were tested to assess whether they could comprehend
the brochure's message. Results showed that, without supplemental inst
ruction, the Exercise Lite brochure was incomprehensible for 69.6% (n
= 39) of the subjects.
