The association between nutrition knowledge and attitude towards dietary intake among competitive elite athletes in DKI Jakarta

Background: Good nutritional knowledge is important for athletes to develop positive attitude and proper dietary practices, especially supporting training, competition, and peak performance. Lack of knowledge can lead to energy and nutrient imbalances, which can disrupt physiological adaptation, recovery, and athletic performance. Unlike previous studies on knowledge, attitude, and practice (KAP), which generally only assess questionnaire scores on eating practices without directly analyzing dietary intake, this study takes a different approach by directly analyzing dietary intake and considering differences between rest days and training days. Objectives: To analyze the association between nutritional knowledge and attitudes towards dietary intake among competitive elite athletes in DKI Jakarta.
