Case Study Final Project
This capstone project requires learners to integrate advanced sports nutrition knowledge by conducting a comprehensive, longitudinal case study on a real individual. The focus is on assessing current health and performance status, identifying nutritional gaps, and designing a personalised, evidence-based intervention plan that adapts over time. Learners will demonstrate practical application of theoretical principles, critical evaluation of outcomes, and ethical practice in a real-world context.
Assessment criteria
Topic Overview
The CFI Level 7 Extended Diploma in Sports Nutrition, accredited by the International Organisation of Performance Nutrition (IOPN), is an advanced qualification designed for professionals seeking to specialise in the science of nutrition for athletic performance. This diploma covers the biochemical, physiological, and practical aspects of sports nutrition, including energy metabolism, macronutrient timing, hydration strategies, and supplementation. It also addresses the role of nutrition in injury recovery, immune function, and body composition management, making it essential for those working with athletes or in high-performance settings.
This qualification sits within the Health & Social Care framework at Level 7, equivalent to a master's degree level, and is vocationally related, meaning it emphasises applied knowledge and skills. Students explore evidence-based practices, critically evaluate current research, and learn to design individualised nutrition plans for diverse athletic populations. The IOPN accreditation ensures the diploma meets rigorous industry standards, preparing graduates for roles such as sports nutritionist, performance coach, or consultant. Understanding this topic is crucial for optimising athletic performance, preventing injury, and promoting long-term health in active individuals.
Key Concepts
Core ideas you must understand for this topic
- →Energy systems and macronutrient metabolism: Understanding how carbohydrates, fats, and proteins fuel exercise at different intensities and durations, including the ATP-PC system, glycolysis, and oxidative phosphorylation.
- →Periodised nutrition: Tailoring nutrient intake to training cycles, competition phases, and recovery periods to enhance adaptation and performance.
- →Hydration and electrolyte balance: The role of fluid and electrolyte intake in thermoregulation, muscle function, and preventing dehydration or hyponatremia.
- →Ergogenic aids and supplements: Evidence-based evaluation of supplements like creatine, caffeine, beta-alanine, and protein powders, including legal and ethical considerations.
- →Body composition assessment: Methods such as DEXA, skinfolds, and bioelectrical impedance, and their application in monitoring training adaptations and health.
Learning Objectives
What you need to know and understand
- 1. Conduct an in-depth, longitudinal analysis and intervention plan of a real-world case subject that aims to support their health and performance.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for a thorough initial assessment that includes dietary analysis, anthropometric measurements, biochemical markers, and physical performance baselines, clearly linked to the subject's sport and goals.
- Demonstrate a phased, theoretically underpinned intervention plan with specific, measurable, achievable, relevant, and time-bound (SMART) goals, justified by current sports nutrition research.
- Provide evidence of regular monitoring and progressive adaptation of the nutrition strategy based on quantitative and qualitative feedback, with critical reflection on its efficacy and any barriers encountered.
- Incorporate interdisciplinary considerations such as sleep, stress management, and training load, showing how nutrition integrates with overall performance and health.
Assessment Guidance
Guidance for achieving higher grades
- 💡Choose a case subject with accessible, reliable data sources and a genuine need for nutritional support to ensure depth and relevance throughout the project.
- 💡Structure your final report with a clear reflective cycle (e.g., Gibbs or Kolb) to demonstrate continuous learning, adaptation, and professional development as a sports nutritionist.
- 💡Use a digital portfolio or logbook to systematically record all interactions, decisions, and evidence of monitoring; this will streamline the assessment of your intervention's progression.
- 💡Always justify your recommendations with scientific evidence. For example, when suggesting carbohydrate loading, cite studies on glycogen supercompensation and specify the protocol (e.g., 10-12 g/kg for 36-48 hours pre-event).
- 💡Use case studies to demonstrate application. Examiners look for the ability to adapt generic principles to individual athletes, considering factors like sport type, training load, body composition goals, and medical history.
- 💡Be critical of research. Acknowledge limitations such as small sample sizes, short durations, or lack of control groups. This shows higher-order thinking and distinguishes top answers.
Common Mistakes
Common errors to avoid in your coursework
- Selecting a case subject without clear performance objectives or measurable outcomes, leading to an unfocused or superficial intervention.
- Relying on generic dietary advice without tailoring to the individual's specific sport, training phase, metabolic demands, or personal preferences, missing the 'real-world' criterion.
- Failing to justify nutritional strategies with appropriate scientific literature or misinterpreting evidence, which can undermine the academic rigour expected at Level 7.
- Neglecting the longitudinal element by only providing a static plan without follow-up, adjustment, or critical evaluation of long-term impact.
- Misconception: 'More protein always means more muscle.' Correction: While protein is essential for muscle repair, excess intake beyond 1.6-2.2 g/kg body weight does not further stimulate muscle protein synthesis and may be stored as fat or excreted.
- Misconception: 'Carbohydrates are bad for athletes.' Correction: Carbohydrates are the primary fuel for high-intensity exercise; adequate intake is critical for performance and recovery. Low-carb diets can impair training adaptations and increase injury risk.
- Misconception: 'Supplements can replace a poor diet.' Correction: Supplements are intended to complement a balanced diet, not substitute for whole foods. Most nutrients are best obtained from food due to synergistic effects and bioavailability.

Before You Start
Prior knowledge that will help with this topic
- •Basic human physiology: Understanding of the digestive, cardiovascular, and muscular systems is essential for grasping nutrient absorption and utilisation.
- •Fundamentals of biochemistry: Knowledge of macronutrient structures, enzyme function, and metabolic pathways (e.g., glycolysis, Krebs cycle) is required.
- •Introductory sports science: Familiarity with exercise physiology concepts like VO2 max, lactate threshold, and energy expenditure helps contextualise nutritional strategies.
