Discussion
In this study we examined the long term effects of teaching aerobic dance on measures of agility and flexibility. No significant differences were found. Schaeffer et al. 15 used 16 instructors to examine the relationship between rating of perceived exertion (RPE) and metabolic responses and found that in this group of experienced teachers that RPE could not be used alone as an indicator of exercise intensity. In that we might expect experienced exercisers to be better able to monitor their responses, it was found that this population was unable to utilize this technique as expected. Similarly we expected our instructors to exhibit significantly better flexibility and agility but failed to find this in this study. Soper et al. 16, used 544 aerobic dance instructors and found that this population did not differ with regard to several descriptive characteristics of general education, formal nutrition information, aerobic dance certifications, and most often used sources of nutritional information. This study concluded that aerobic dance instructors did not differ from the normal population in terms of nutritional information and many desired more nutritional education.
