GLOSSARY

Sports Nutrition Assessment An integrated evaluation of an athlete's nutritional needs, intake, health, training demands and practical circumstances.

Choose a dietary assessment method according to the question, population and resources. A recent intake record can explore meal timing around training; a frequency questionnaire can describe longer-term patterns. Neither automatically establishes exact habitual intake. Combine food details with training, access, symptoms, medication and relevant measurements. Explain uncertainties and what the method cannot answer. Good assessment produces a decision that can be reviewed, rather than an impressive nutrient report whose apparent precision exceeds the quality of the information collected.

Sports nutrition connects food and fluid provision with training, competition, adaptation and health. The appropriate plan depends on the sport, event duration, athlete, environment and available eating opportunities. Adequate energy and nutrient intake form the foundation, while timing and specialized products solve particular problems. A strategy supported in one exercise model is not automatically optimal for every sport. The useful outcome is the athlete's ability to train, recover and perform under the actual conditions.

Energy availability describes dietary energy remaining after exercise expenditure, expressed relative to fat-free mass over a defined period. It differs from whole-day energy balance and from body-fat percentage. Calculations are sensitive to errors in food records, exercise expenditure and body-composition estimates. No single threshold or short observation establishes a diagnosis for every athlete. Persistent fatigue, impaired recovery or other concerning changes warrant assessment in the broader health and training context rather than a conclusion from one calculated value.

Usual intake describes a longer-term average rather than the intake of one isolated day. Day-to-day variation includes real differences between training, rest and competition days as well as measurement noise. Repeated observations should cover relevant conditions and be collected with a suitable method. Averaging a few unusual days can still give a misleading estimate. For the athlete, preserve useful information about distribution and timing: an acceptable weekly energy average can coexist with repeated underfueling around demanding sessions.

A nutrition care record should explain the assessment, interpretation, agreed plan, responsible professionals and follow-up criteria. Separate reported information from measured findings and clinical judgments. Record relevant units, dates, methods and changes so that another practitioner can understand the decision. Seek consent for sharing sensitive information and limit access appropriately. A referral should communicate the specific concern and urgency rather than only a broad label. In sport, documentation should support continuity of care while protecting health information from inappropriate use in coaching or selection.
