Phosphocreatine

A high-energy phosphate system supporting rapid ATP regeneration, particularly relevant to brief maximal efforts and repeated high-intensity exercise contexts.

Muscle glycogen

Stored carbohydrate available for use within muscle, with a role distinct from the liver’s contribution to circulating glucose regulation.

Fuel availability

The practical and physiological accessibility of appropriate substrates for the intended work, influenced by total intake, timing, stores, and delivery.

Protein distribution

The pattern of protein opportunities across meals and recovery, considered alongside total adequacy, quality, energy intake, and individual needs.

Sweat-rate estimate

An approximation of sweat loss over time based on a defined protocol and relevant inputs and outputs, not an exact universal future fluid prescription.

Sweat sodium concentration

The sodium amount per sweat volume under a sampling method and context, distinct from total sodium loss and blood sodium status.

Exercise-associated hyponatremia

A potentially serious exercise-related low blood-sodium condition requiring appropriate clinical assessment, which cannot be ruled out by assuming all symptoms mean dehydration.

Ergogenic evidence

Research relevant to a performance intervention in a specified task, formulation, population, and context, rather than a guarantee for every commercial product.

Third-party certification

Independent product testing or verification within a stated programme, useful for reducing some supplement risks but not proving zero risk or efficacy.

Nutrition periodization

Adjustment of nutrition strategies to training and competition demands while maintaining health and overall adequacy, rather than imposing identical restriction every day.

Energy availability

Dietary energy remaining after exercise expenditure relative to fat-free mass, estimated with uncertainty and interpreted alongside broader clinical information.

REDs

The IOC framework describing health and performance consequences associated with problematic low energy availability in female and male athletes.

Screening

A process identifying possible concerns for further assessment, distinct from a complete diagnosis or an automatic decision about sports participation.

Ferritin

A marker used in evaluating iron stores that can also be influenced by inflammation, requiring context and appropriate related measurements.

Lactose intolerance

Difficulty digesting lactose with variable symptom and dose tolerance, distinct from an immune reaction to the proteins in milk.

Celiac disease

A condition requiring an appropriate gluten-free dietary pattern and cross-contact attention, with diagnosis coordinated before changes that can affect testing.

Medical nutrition therapy

Individualized nutrition assessment and intervention for clinical needs, including practical monitoring and coordination with the relevant healthcare and athlete-support team.

Delayed hypoglycemia

Low blood glucose that can occur after exercise rather than only during it, relevant to individualized monitoring and food-medication planning.

Measurement error

Uncertainty arising from tools, protocols, inputs, or biological variation that limits how precisely an estimate represents the quantity being interpreted.

Nutrition etiology

The identified cause or contributing factor addressed by a nutrition intervention where feasible, such as restricted meal access rather than assumed lack of motivation.

Cross-contact

Unintended transfer of an allergenic or restricted ingredient through products, equipment, utensils, handling, or service despite an apparently suitable recipe.

Standardized recipe

A defined formulation and method with a stated yield and portions, supporting consistency while requiring appropriate adjustments and safety review when scaled.

Edible yield

The usable fraction of a purchased food under a defined preparation process, needed to distinguish raw purchasing quantity from served edible quantity.

Traceability

Records connecting a product and lot with source, dates, distribution, and recipients, allowing a targeted response to recalls or other identified concerns.

Reorder point

A stock threshold derived from a stated demand, lead-time, and safety-stock model, whose assumptions should be checked against actual operational variation.

Process measure

An indicator of programme delivery or activity, such as materials distributed, distinct from proof of understanding, intake, health, or performance change.

Outcome measure

An observation aligned with a programme’s intended effect, requiring suitable methods and interpretation rather than assuming activity automatically caused improvement.

Teach-back

An educational approach in which the athlete explains or demonstrates the plan, allowing the practitioner to check understanding and correct gaps.

Food access

The athlete’s practical ability to obtain and use appropriate food within scheduling, financial, cultural, storage, travel, and other real constraints.

Conflict of interest

A relationship or incentive that must be identified and managed so recommendations remain grounded in evidence, professional judgment, and athlete needs.
