This study assessed the sports nutrition knowledge of current and prospective physical educators/coaches (HPEs) to determine the need for improved education in this area and to compare the nutrition knowledge of HPEs with that of foods and nutrition students (FNSs) and general college students (GENs). A researcher-developed 4-point Likert-type scale, which contained 70 statements, was administered to 58 students representing a cross-section of health and physical education majors enrolled in upper-level major courses, 27 students in 2 upper-level home economics foods and nutritions courses, and a general group comprised of 20 students in non-health/physical education classes. Statements on the scale assessed nutrition supplementation, fluids and hydration, pre-event nutrition, nutrition composition, nutrition terminology, general nutrition, and nutrition opinion. The dependent variable was sports nutrition knowledge. Frequencies and percentages were computed for all items on the scale. Group mean differences were computed and compared by a one-way analysis of variance. The sports nutrition knowledge of HPEs tested is inferior to standard competency levels. Significantly higher means scores for FNSs were found. Education and information sources for HPEs are insufficient. Currently, interscholastic athletic coaches have little direct control over the dietary behaviors of student-athletes. Five tables are included. (RLC)
