Abstract
There are multiple influences on food choice for athletes. The aim of this study was to assess the validity and reliability of a Turkish Athlete Food Choice Questionnaire (Turkish-AFCQ) and describe the main factors influencing food choices. A multi-step process of language and content validation, Explanatory Factor Analysis, Confirmatory Factor Analysis, and test-retest reliability were used to examine factorial structure and construct validity (convergent and discriminant) and reliability (internal and external). The translated Turkish-AFCQ was administered to 446 athletes (59% male, median age = 21 years) from a variety of sports. The original nine-factor structure was validated, external reliability was acceptable, and all factors achieved acceptable discriminate validity. Convergent validity and internal reliability received tenable-ideal ratings for seven and eight factors, respectively. Interpretation and future application are discussed for low-performing factors 'food and health awareness' and 'influence of others'. The factor most frequently (never 1-always 5) influencing choices was 'performance' (Md = 4.33) and the least was both the 'influence of others' and 'food values and beliefs' (Md = 2.67). The Turkish-AFCQ can be used to expand researchers' and practitioners' understanding of the relative influence multiple factors have on food choices, and this study provides a model for AFCQ linguistic translation and validation.

Abstract
Introduction Sports nutrition is a rapidly growing sector with increasing demand for evidence-based nutritional products to support competitive and healthy lifestyles. The product development process for novel foods should rely heavily on end-user engagement to facilitate future success, however there is a dearth of published information available. An understanding of the practices and self-reported nutritional priorities of athletes and active individuals is required for the development of new food products, facilitating evidence-based product formulation. Methods Participants were at least 18 years of age, actively participating in competitive sport or structured physical activity on at least two occasions per week. Participants were asked to undertake a comprehensive online survey assessing their nutritional practice, perceived nutritional priorities and preferences for product characteristics. Questions were developed on the basis of critical evaluation of the current scientific literature and the hosting of two scoping focus group sessions with prospective end-users. Results 405 individuals (29 ± 9 years) completed this questionnaire. 295 participants reported active participation in competitive sport while the remaining 110 participants undertook structured physical activity exclusively. When asked to rank their top three most sought-after product claims in sports nutrition, "enhanced muscular recovery" was the most prioritised receiving 101 first choice preferences (25%) and 295 top 3 preferences. Fifty-eight percent of participants reported taking nutritional supplements. Caffeine containing functional foods (excluding caffeine supplements) were the most commonly used functional food group. A very low incidence of functional food usage was reported otherwise. When asked to rank the importance of various food product attributes, "nutritional profile" was ranked as the most important with rating of 3.37 ± 0.7 out of 4 followed by "taste" and "accessibility". Whole food nutritional products received the most first preference selections and most top 3 selections when presented with a number of popular performance and recovery products on the market. Conclusions The transition towards a food first approach in sports nutrition is vital for athletes and active individuals to achieve their goals; with the development of evidence-based functional foods, particularly with a focus on muscle recovery, endurance, and strength enhancement at the forefront for new food product design and innovation.

Abstract
Understanding the factors that influence an athletes' food choice is important to supporting optimal dietary intake. The Athlete Food Choice Questionnaire (AFCQ) is a new validated tool for assisting practitioners and researchers to understand athlete eating behaviours. However, the AFCQ previously has only been applied at international competition events. This observational study explored the online application of the AFCQ outside of the competition environment with detailed examination of factor reliability. The AFCQ factors include 'nutritional attributes of the food', 'emotional influences', 'food and health awareness', 'influence of others', 'usual eating practices', 'weight control', 'food values and beliefs', 'sensory appeal', and 'performance'. A total of 131 athletes, representing 19 countries and 36 sports, participated using an online questionnaire. Reliability via Cronbach's alpha (α) and item correlation scores were compared to those from previous competition events. Acceptable reliability was attained for seven of the nine factors (α ≥ 0.7, range 0.70-0.92). 'Food values and beliefs' and 'usual eating practices' (α = 0.60, 0.64) were tolerable and consistent against previous major competition samples, indicating that the setting is unlikely responsible for lower reliability scores. Three factors ('emotional influence'; 'nutritional attributes of the food'; 'influence of others') differed in reliability between the online sample compared to one or both major competition samples. The 'religious food beliefs' item within the 'food values and beliefs' factor may warrant removal due to recurrent low internal consistency. This study confirms the AFCQ's reliability regardless of competition phase and supports use of the AFCQ for understanding the eating behaviours of athletes.

Abstract
BACKGROUND The individual determinants of food choice have been extensively investigated in the general population, but there have been limited studies in athletes. A better understanding of the food making decisions can help to target interventions that lead to optimal intake for athletes' health and performance. A scoping review will provide an understanding of the sports and settings that have been investigated, the methods and approaches to assessing food choice, as well as the factors influencing food choice. OBJECTIVE The objective of this review was to map the available evidence on the multi-faceted determinants of food choice in athletes and describe key influences impacting their choices. ELIGIBILITY CRITERIA Athletes 16 years and over from any country who engage in physical activity with the intent to be competitive. Studies were included if they reported the multi-faceted determinants of food choice as either a primary or secondary outcome. All study designs were considered. SOURCES OF EVIDENCE This review followed the PRISMA extension for Scoping Reviews. Eleven databases including PubMed, Web of Science (Clarivate Analytics), SPORTDiscus (EBSCO), PsycNET (APA), Health Collection (Informit), CINAHL (EBSCO), the Cochrane Library, ProQuest Dissertations and Theses Global, Trove (National Library of Australia), JBI (Ovid), and Google scholar were searched between September-November 2020 and updated in March 2021. Charting of Data Search results were screened with selected studies extracted into a summary table established a priori by the authors. Study quality was assessed using standardised reporting tools for qualitative and quantitative research designs. The scope and quality of evidence was summarised and reported. RESULTS A total of 15 studies were included. Qualitative research included one research thesis and six primary research studies using both focus groups and semi-structured interviews. Quantitative research included one research thesis and seven primary research studies with cross-sectional design using different validated and non-validated survey instruments. No longitudinal or intervention studies were found. The majority of studies have been published since 2018 and conducted across multiple countries with either mixed cohorts of athletes or focused on predominately endurance or team sports. The quality of reporting was variable, particularly for qualitative research. Outcomes suggested that performance and health were relevant to athlete food choice, with varying impact of competition season, the level of experience, the culture of the sport, the cultural background or nationality of the athlete, athlete sex and the food environment. CONCLUSION More research is needed on the multi-faceted determinants of food choice in different cohorts of athletes, particularly females. Future research could explore the relationship between food choice, nutrition knowledge and diet quality or the change in food choice across the phase of the seasons and through injury and illness. Use of validated measurement tools and robust reporting will enable critical interpretation of the study methods and outcomes for use in practice.

Abstract
Carbohydrate (CHO) intake during exercise can optimize endurance performance. However, there is limited information regarding fueling practices of endurance athletes during training. Accordingly, an anonymous German-language online survey was circulated examining the determinants of CHO choices, and intake practices among runners, triathletes, and cyclists during training. Survey questions included predefined answers, and a Likert scale with response of CHO food choice intakes from 1 = never to 5 = always. 1,081 endurance participants (58.0% male, 68.6% aged 18–39 years) of varying competitive levels were included in the analysis. Overall, most participants consumed a combination of commercial sport nutrition products and everyday foods (67.4%, n = 729) with their primary reason that food-first was preferred, but in some exercise scenarios, commercial sport nutrition products were deemed more convenient (61.3%, n = 447). Participants consuming commercial sport nutrition products only (19.3%, n = 209) most often valued their ease of intake during exercise (85.2%, n = 178). Among those consuming everyday foods only (13.2%, n = 143), the most common reason was the perceived importance of eating wholesome foods/natural ingredients (84.6%, n = 121). Between the most frequently consumed CHO sources during training at low-to-moderate intensities (n = 1032), sports drinks (mean ± SD; 2.56 ± 1.33) were consumed significantly more often than bananas (2.27 ± 1.14, p < 0.001), with no significant difference in intake frequency between bananas and traditional muesli/fruit/energy bars (2.25 ± 1.14, p = 0.616). Whereas during high intensities (n = 1,077), sports drinks (3.31 ± 1.51) were significantly more often consumed than gels (2.79 ± 1.37), and gels significantly more often than energy bars (2.43 ± 1.28), all commercial sport nutrition products (all, p < 0.001). Overall, 95.1% (n = 1028) of all participants consumed CHO during training at all exercise intensities, with males (n = 602; 2.35 ± 0.70) consuming significantly more often commercial sport nutrition products than females (n = 424; 2.14 ± 0.79, p < 0.001); females consumed significantly more often everyday foods than males (1.66 ± 0.47 vs. 1.54 ± 0.42, p < 0.001). Most participants used mixed CHO forms during low-to-moderate (87.9%), and high exercise intensities (94.7%). 67.6% (n = 731) of all participants reported guiding their CHO intake rates during training by gut feeling. These large-scale survey findings suggest a preference of endurance participants’ CHO intake during training in liquid form independent of exercise intensities and offer novel insights into CHO intake practices to guide sports nutrition strategies and education.

Abstract
PURPOSE The Athlete Food Choice Questionnaire (AFCQ) is a novel tool for understanding factors influencing athlete food selection and providing context to nutrition knowledge and diet quality data. Reliability, face, and content validity have been previously established during development. The aim of this study is to evaluate the AFCQ's factorial structure, reliability, and construct validity in an independent sample of international high-performance athletes. METHODS The AFCQ contains 36 items within nine factors. Participants rate how frequently (1 never to 5 always) items influence their choices. Model consistency and construct validity was evaluated by confirmatory factor analysis. Measures included model fit incidences and duplicate methods examining reliability, convergent, and discriminant validity. RESULTS Athletes (n = 232) at the 2018 Commonwealth Games, Gold Coast, Australia, completed the AFCQ. A modified 32-item model achieved discriminant validity for all factors and convergent validity for "emotional influence," "food and health awareness," "nutritional attributes of food," "performance," and "influence of others." Reliability measures of all constructs except "usual eating practice" and "food values and beliefs" were above acceptable thresholds, although "usual eating practice" was considered tolerable and conditionally accepted. CONCLUSION The AFCQ was confirmed in its original nine-factor structure in an independent sample of high-performance athletes. This provides a detailed and transparent account of the construct validity of the AFCQ, adding to the foundation of evidence for this new instrument. The AFCQ captures the unique influences specific to athletes while being broad enough for application across diverse sporting and culturally mixed cohorts. This tool could assist sports science professionals in making more informed and effective decisions around strategies to support athletes, including the ability to triage for specific sports nutrition advice.

Abstract
Background Food frequency questionnaires are considered an effective method for assessing habitual dietary intake, but they must be developed or validated with the target population. Portion size, supplement use and food choice are thought to be especially important methodological considerations for assessing athletes’ dietary intake. This study aimed to develop and validate a food frequency questionnaire for Japanese athletes using data from this population. Methods We used dietary records from 440 Japanese athletes involved in our previous projects. Food items were analyzed using cumulative percentage contributions and multiple regression analysis, to give a selection of 62 basic food items and four supplemental items. The validity of the questionnaire was evaluated among another 77 Japanese athletes by comparing nutrient intakes assessed using the questionnaire with dietary records. Reproducibility was evaluated by comparing a second questionnaire completed 2–3 weeks later by 36 of the athletes in the validation study. Validity was assessed using crude Spearman’s correlation coefficients (CCs), energy-adjusted CCs, intraclass CCs (ICCs), and Kappa index values. Reproducibility was assessed by CCs, energy-adjusted CCs, and ICCs. Results In the validation analysis, the median crude CC for all of the nutrients was 0.407, ranging from 0.222 for dietary fiber to 0.550 for carbohydrate. The median energy-adjusted CC was 0.478, and the median ICC was 0.369. When we divided the athletes into quartiles, 65% (vitamin B1) to 86% (iron) of athletes were classified into the same or adjacent categories using the questionnaire and dietary records, with a median Kappa statistic of 0.32. In the reproducibility analysis, the median crude CC between the two completed questionnaires was 0.654, ranging from 0.582 (carbohydrate) to 0.743 (vitamin B2). The median energy-adjusted CC was 0.643, and the median ICC was 0.647. Conclusions The new 62-item food frequency questionnaire is both reliable and valid and may be useful for assessing food intake in Japanese athletes.

Abstract
This study aimed to identify the factors influencing the food choices of athletes at the Universiade and Commonwealth Games and explore differences in the cohort across sport, competition history and demographic characteristics. A sample of 385 athletes (n = 153, 2017 Universiade, Taiwan; n = 232, 2018 Commonwealth Games, Australia), from 69 countries and 29 sports participated in this cross-sectional observational study. Participants rated 36 items from the Athlete Food Choice Questionnaire and 11 additional items (gut comfort, doping risk, availability, location, money, convenience, time of day, hunger, medical conditions, and food allergies) on how frequently (1 never to 5 always) each influences their food choices. "Performance", "sensory appeal", "food and health awareness" and "weight control" were reported as most frequently, while the least were "emotional influence", "influence of others" and "food values and beliefs". Commonwealth Games athletes were older, more experienced and more likely to report "performance" (median = 4.33 versus 4.00, U = 20250.0, p = 0.012) and less likely to report "emotional influences" (median = 2.80 versus 3.20, U = 14273.0, p = 0.001) than Universiade athletes. Greater numbers of younger athletes were often or always influenced by available money. Athletes across all sports reported frequently considering gut comfort in their food choices. These results can inform nutrition education strategies of high-performance athletes.

Abstract
The selection of foods made by athletes during competition can impact performance, yet to date, the quality of their food choices has not been investigated. The aim of this study was to describe the food selection of athletes in a buffet-style dining hall setting in terms of diet quality, food variety, and volume of food and compare to their self-rating of their meal, reasons for the choosing the food items, access to previous nutrition advice, and use of nutrition labelling. A total of 81 athletes (42 females, 39 males) from 24 sports across 58 countries at the 2018 Commonwealth Games (Qld, Australia) participated in this study. A digital photograph was taken of the athletes' meal after selection from the buffet and prior to consumption. Each participant was asked a series of questions in relation to their food selection. The photographs were coded into recommended serves of food groups based on the Australian Guide to Healthy Eating. The nutritional analysis and photograph of a standard serve size were used to quantify the energy and nutrients for the meal. Most athletes chose adequate quantities of macronutrients, which agreed with their reasons for the food choice, but the majority did not include fruit (80.2%) or dairy (65.4%) in their food selection, while 54% of males included discretionary foods (0.25-7.0 serves). The median self-rating for food choice was 8/10. Most reasons for food choices were nutritional attributes, sensory factors, performance, usual eating practices and physiological factors (e.g., satiety, gut comfort). This suggests that athletes may need more education on the quality of food selected from buffet settings.
