360o Metabolic Blue Print
The 360° Metabolic Blueprint is i-Thrive’s most advanced performance assessment — designed to provide a truly complete map of how your body produces energy. Instead of looking at isolated metrics, the Blueprint examines your entire metabolic system, including aerobic capacity, anaerobic power, energy efficiency, and race-specific fuel usage. This is the same modelling used in WorldTour performance labs and elite endurance programmes.
This test goes beyond lactate testing, adding insights that only come from integrating VO₂max, running/cycling economy, energy-system interaction, and detailed fat–carb combustion analysis.
What the Metabolic Blueprint Measures
The Blueprint provides a full physiological profile, including:
- VO₂max – your aerobic ceiling and oxygen uptake capacity
- Economy – how efficiently you convert oxygen into speed or power
- VLaMax – glycolytic (anaerobic) power and lactate production rate
- Fat vs carbohydrate combustion across all intensities
- Lactate accumulation and clearance behaviour
- Anaerobic Threshold based on real metabolic modelling
- Aerobic vs anaerobic energy contribution ratios
- Energy cost of racing intensities
- Fuelling needs and depletion risk for specific event durations
- Optimised training zones based on your metabolic fingerprint
- This assessment shows not just how fit you are, but how your fitness is created — and which levers will produce the biggest performance gains.

Why Body Composition Is Essential for Accuracy
The Blueprint becomes significantly more accurate when paired with i-Thrive’s body composition testing.
INSCYD is the only system in the world that normalises VO₂max, VLaMax, thresholds, fat-carb usage, and economy to your lean mass and fat mass, rather than generic population assumptions.
This matters because:
1. Lean mass determines metabolic power
The amount of active muscle tissue directly affects:
- Oxygen consumption
- Lactate production
- Fuel turnover
- VLaMax
- Efficiency
- Accurately understanding lean mass ensures we interpret VO₂, thresholds, and glycolytic function correctly.
2. Fat mass influences energy cost and relative intensity
Without correct fat-mass measurement, metabolic efficiency appears distorted. This is especially important for:
- Endurance athletes
- Hyrox athletes
- Weight-sensitive sports
- Anyone managing fuelling or performance plateaus
3. Fat–carb utilisation depends on total active tissue
Fuel-combustion curves are only truly accurate when normalised to the correct ratio of active (lean) to inert (fat) tissue.
This is why body composition is not optional — it is fundamental for correct metabolic profiling. Every Blueprint test at i-Thrive includes a 3D infrared full-body scan, providing:
- Lean & fat mass
- Fat distribution patterns
- Limb asymmetry
- Posture and alignment
- Circumference data for normalising metabolic output
This enhances the precision of all metabolic calculations and ensures your Blueprint results are tailored to your body, not generic models.
Optional Upgrade: DEXA Body Composition (Clinical Gold Standard)
For athletes wanting the highest possible accuracy, you can upgrade to a DEXA Body Composition & Bone Density scan, providing:
- Exact lean mass (total and regional)
- Exact fat mass (total and regional)
- Appendicular lean mass (arms + legs)
- Visceral fat
- Bone mineral density (BMD)
DEXA adds clinical-grade accuracy in identifying:
- Low energy availability
- Early RED-S indicators
- Muscle imbalances
- Metabolic efficiency limitations
- Pairing DEXA with the Blueprint creates the most complete metabolic assessment available in the UK for endurance and performance athletes.
- The 360° Metabolic Blueprint is a complete, VO₂-based, economy-based, lactate-aware, fuel-usage-modelled metabolic assessment.
- It goes beyond lactate testing by incorporating VO₂max, economy, energy modelling, and efficiency analysis.
- It is the only assessment that adjusts all outputs to your body composition, making use of 3D scanning and optional DEXA.
- It delivers a full metabolic footprint showing how you produce energy and exactly where performance gains will come from.

Lactate Performance Profile
Best for: maximum metabolic accuracy, threshold work, and detailed fuelling strategy.
The Lactate Performance Profile is an in-lab test that measures how your blood lactate responds across increasing intensities. Unlike a simple “threshold test”, this protocol allows INSCYD to:
- Measure (not just estimate) your VLaMax
- Identify how quickly you accumulate and clear lactate
- Pinpoint your true anaerobic threshold
- Map your fat and carbohydrate usage at each intensity
- Define sustainable race pace and training zones with much greater precision
- Why body composition really matters here
The Importance of Body Composition
INSCYD is the only system that normalises performance data to body composition – including VO₂max, thresholds, fat–carb usage and VLaMax. That matters because:
- Lean mass is what drives oxygen use, lactate production and fuel turnover
- Fat mass can dilute performance numbers if you only look at watts or pace
- Accurate fat vs lean mass is essential for correctly interpreting your metabolism
To support this, every Lactate Performance Profile at i-Thrive includes a 3D Infrared Body Scan as standard in the Lactate Performance Profile. This includes:
- Detailed shape and circumference data
- Visual insight into fat distribution and muscle development
- A more accurate basis for normalising your metabolic results than weight or calipers alone
You can choose to upgrade your Lactate Performance Profile with a DEXA Body Composition & Bone Density scan, the clinical gold standard for:
- Total and regional lean & fat mass
- Appendicular lean mass (arms + legs) – critical for endurance and power
- Visceral fat
- Bone mineral density (BMD)
BMD and appendicular lean mass are particularly important in identifying athletes who may be at risk of Relative Energy Deficiency in Sport (RED-S), where low energy availability can compromise bone health, hormones and performance.
Combining Lactate testing + INSCYD + 3D scan (+ DEXA if upgraded) gives you the most accurate picture possible of how your body composition and metabolism interact.
