A framework for translating consensus evidence into an individual decision.

A position stand is one of the most useful starting points in sports nutrition. It brings a defined topic, a body of literature and expert interpretation into one document. It does not remove the need for professional judgement.

The International Society of Sports Nutrition has published position stands on subjects including creatine supplementation, protein and exercise, and diets and body composition. These papers can orient learners and practitioners, identify supported conclusions and reveal where evidence remains conditional or incomplete.

What a position stand can provide

A strong position stand defines its topic, reviews relevant evidence and presents practical conclusions at a particular point in time. It can help a reader understand terminology, typical protocols, safety considerations, population differences and key references.

It is best used as an evidence map. The map shows important routes and boundaries. It does not know the individual standing in front of you.

Step 1: define the real decision

Do not begin with the topic alone. “Creatine” is not a decision. The decision may be whether creatine monohydrate is appropriate for a healthy adult strength athlete seeking to support training adaptations, given their diet, goals, budget, medical history and anti-doping responsibilities.

Step 2: identify the population and conditions

Check whether the evidence reflects the person’s age, sex, training status, sport and health. Position stands often cover broad evidence, while individual studies may be concentrated in particular groups. Transfer should be reasoned, not assumed.

Step 3: separate general principle from protocol

A general conclusion that protein intake supports exercise adaptation does not prescribe the same daily intake, distribution or food strategy for every person. Body mass, total energy, training, dietary pattern, preferences and clinical considerations affect implementation.

Step 4: examine the outcome

An intervention may influence strength, lean mass, repeated-sprint performance, soreness, a blood marker or subjective recovery. Those outcomes are not interchangeable. Match the evidence to the outcome that matters.

Step 5: add safety, quality and regulation

Consider contraindications, medication, allergies, gastrointestinal tolerance, product testing, label accuracy and sport rules. Where medical assessment or therapeutic nutrition is involved, refer or collaborate within the appropriate regulated pathway.

Step 6: test feasibility

A theoretically optimal plan that an athlete cannot afford, access or follow is not an effective plan. Translate the evidence into food, timing and monitoring choices that fit the person’s routine and culture.

Step 7: monitor and update

Define what success looks like and when it will be reviewed. Monitor performance, tolerance, adherence and relevant health indicators. Check whether newer evidence or an updated position stand changes the recommendation.

Three examples of careful translation

Creatine

The ISSN position stand supports creatine monohydrate as one of the most studied ergogenic supplements, particularly for high-intensity exercise and training adaptations. Practice still requires attention to goal, dosing approach, product quality, tolerance and individual context.

Protein

The ISSN protein position stand discusses intake and timing in active people. Application starts with total diet, energy availability and training demand; supplements are tools, not automatic requirements.

Diets and body composition

The ISSN position stand describes multiple dietary approaches and emphasises that body-composition outcomes are strongly influenced by energy balance, adherence and individual context. A named diet is therefore not a universal prescription.

A practical translation sentence

Before acting, complete this sentence: “For this person and outcome, the evidence supports considering this approach, under these conditions, while monitoring these factors.” The sentence makes individualisation and uncertainty visible.

Position stands are powerful because they organise evidence. Professionals add value by translating that evidence carefully, transparently and within scope.

Create a one-page evidence-to-action record

For a real or simulated case, write the decision question, relevant position-stand statement, key individual context, proposed action, safety and scope checks, monitoring plan and review date. Cite the exact section or source used.

This record makes translation auditable. A supervisor can challenge the reasoning, a colleague can understand the plan and the practitioner can update it when the person’s response or the evidence changes. Documentation turns “I followed the science” into a transparent process.
