摘要

The nutritional intake of ultraendurance athletes is often poorly matched with the requirements of the sport. Nutrition knowledge is a mediating factor to food choice that could correct such imbalances. Therefore, the purpose of this study was to develop and validate a questionnaire to assess the nutrition knowledge of ultraendurance athletes. Nutritional knowledge was assessed using a modified sports nutrition knowledge questionnaire (ULTRA-Q). Four independent assessors with specialization in sports nutrition confirmed the content validity of the ULTRA-Q. Registered sports nutritionists, registered dietitians, and those without nutrition training completed the ULTRA-Q on two separate occasions. After the first completion, a significant difference in nutrition scores between groups (p = .001) provided evidence of construct validity. After the second completion, intraclass correlation coefficients comparing nutrition scores between time points (.75-.95) provided evidence of test-retest reliability. Subsequently, experienced ultraendurance athletes (male: n = 74 and female: n = 27) completed the ULTRA-Q. Athletes also documented their sources of nutrition knowledge for ultraendurance events. The total nutrition knowledge score for ultraendurance athletes was 68.3% +/- 9.5%, and there were no significant differences in knowledge scores between males and females (67.4% +/- 9.6% and 70.7% +/- 9.3%, respectively) or between runners and triathletes (69.1% +/- 9.7% and 65.1% +/- 9.4%, respectively). In general, it appeared that ultraendurance athletes favored other athletes (73%) over nutrition experts (8%) as a source of nutritional information. The findings of this study indicate that ultraendurance athletes had a reasonable level of nutrition knowledge, but interathlete variability suggests a need for targeted nutrition education.
