An assessment was made of the extent of nutrition knowledge of physical education teachers and coaches. The investigation addressed three primary questions: (1) Do practicing physical educator/coaches possess nutritional knowledge comparable to that of college students enrolled in a university basic nutrition class?; (2) Do male and female physical educator/coaches exhibit similar levels of nutrition knowledge?; and (3) Within a single group, are differences in knowledge evident when examining selected categories of information?. Questionnaires were submitted to participants in the 29th Annual California Workshop for Physical Education and Athletic Coaching. It was concluded that these professionals did not possess dietary knowledge equal to that of students taking a university basic nutrition class. No differences were found in the knowledge level of male and female coaches, and both groups exhibited deficient levels of information which fluctuated from category to category. These findings support the contention that physical educator/coaches are not adequately prepared in nutritional science, and a need exists for better preservice and inservice training. (JD)
