Abstract

Background: Sports nutrition knowledge is an essential competency for personal trainers in supporting client health, safety, and fitness goal attainment. This study aimed to determine the level of sports nutrition knowledge among personal trainers and to identify the relationships among nutrition knowledge components. Methods: A descriptive quantitative approach with a cross-sectional design was applied. A total of 102 personal trainers in Surabaya were recruited using convenience sampling. Data were collected using the Abridged Nutrition for Sport Knowledge Questionnaire (A-NSKQ), which assesses general nutrition knowledge, sports nutrition knowledge, and supplement knowledge. Data were analyzed using descriptive statistics and inferential analysis with Spearman rank correlation tests Results: Most personal trainers demonstrated a low level of sports nutrition knowledge (69.6%), and total A-NSKQ scores were predominantly classified as low (60.8%). General nutrition knowledge was classified as moderate to good and was not accompanied by adequate sports nutrition knowledge. Correlation analysis revealed significant positive relationships between general nutrition knowledge, sports nutrition knowledge, and total A-NSKQ scores. Conclusions: The level of sports nutrition knowledge among personal trainers in Surabaya remains low. These findings indicate the need for competency development through evidence-based sports nutrition education and training to enable personal trainers to provide accurate, safe, and effective nutrition recommendations in support of client fitness goals.

Abstract

Background: Football is a highly popular sport worldwide, including in Indonesia. In football matches, referees play a crucial role that significantly determines the course of the game and its final outcome. However, this role often leads to pressure that can trigger anxiety due to physical, mental, and emotional demands from various parties such as players, coaches, and spectators. This study aims to analyze the level of anxiety experienced by Indonesian football referees when officiating professional matches. Methods: This study uses a descriptive quantitative approach with surveys as the data collection method. The research sample consists of 21 professional football referees in Indonesia, aged 25-40 years, with 1-18 years of experience. The research instrument used is the Football Referee Anxiety Scale (FRAS) questionnaire, covering four dimensions of anxiety: cognitive, affective, somatic, and motoric. Results: The study results show that the majority of referees have a low level of anxiety, with an average score of 67.19. A total of 52.4% of referees have low anxiety, while 33.3% fall into the high category. The most prominent aspects of anxiety are cognitive and affective dimensions, where several referees experience difficulties in decision-making and emotional burdens Conclusions: The level of anxiety among Indonesian football referees when officiating professional matches varies. Most referees have a low level of anxiety. The most frequently affected aspects of anxiety include the cognitive and affective dimensions, which involve feelings of worry, difficulty concentrating, and emotional burdens. Keywords: anxiety; referee anxiety; football referee
