CSSD - Sports Dietetics · Get comfortable with the vocabulary.
- 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.
