About this trial
This study evaluates the dietary intake of professional female footballers against nutritional guidelines, analysing differences by age, position, and location (UK vs Spain). Using a cross-sectional design, it will include 20-30 players per club from four clubs, aged 18+, collected via the Snap-N-Send method and analysed with Nutritics software. Variables include energy intake, macronutrients, and micronutrients, with data assessed using MANOVA, t-tests, and Shapiro-Wilk tests. The aim is to determine dietary adequacy and provide insights to improve nutrition education and wellbeing for female athletes.

Dietary assessment
BehavioralDietary intake data will be collected using the Snap-N-Send method, a tool with enhanced validity for assessing athlete total energy intake, where participants will take photographs of their meals and share them via WhatsApp directly with the researcher. Before the study commences, participants will receive standardised instructions on photographing food and adding details in the message such as title, portion sizes and ingredients alongside each photo to enhance data precision. The principal investigator will input these photographs with the added information into Nutritics dietary analysis software, where food weights, portion sizes, and nutritional content will be estimated and calculated. Nutritics will then calculate dependent variables and convert it into a food diary report, aggregating the three days of food diary into average intake.
