Athletic Performance
You train just as hard, but they recover in 24 hours, and you need a week.
Power athlete trapped in an endurance body (or vice-versa)?
From the report
The biology this section covers.
Genetics plays a major role in athletic potential. Think of it like having a fast car: the engine matters, but so does the driver, the fuel, and the maintenance.
Your genetic profile helps answer practical questions: Are you built more for endurance or power? How quickly can you build strength? How fast do you recover? Where are you more prone to injury? Understanding these patterns helps you train smarter, focusing effort where your genetics will reward it most and protecting the areas where you're more vulnerable.
The story this section tells
What your DNA is doing under the hood. Why it matters today.
Your muscle fiber ratio, your VO₂ ceiling, your tendon resilience, and your recovery rate—all shaped at birth—shape what training truly benefits your body versus what simply wears you down.
You'll stop following programs designed for different physiologies and finally train in a way your body actually responds to—leading to faster progress, fewer injuries, and less confusion.
This one is for you if…
You work hard, but progress feels painfully and inexplicably slow.
What you'll see in your Athletic Performance report.
Every insight below appears as a personalized dark card in your full Mosaic report, with a color marker tuned to your specific genetic variants and a practical next step you can act on.
Aerobic Capacity (VO₂ Max)
4 insights
Cardiovascular VO2 Max
Your heart's stroke volume and oxygen delivery set your aerobic baseline before you ever lace up a shoe. This tells you how much endurance potential you're starting with—and how to train it most efficiently instead of wondering why you're gasping while your training partner chats.
Read insight →Metabolic VO2 Max
How efficiently your cells turn oxygen into usable energy (ATP) sets your daily stamina and workout capacity. If yours is naturally lower, targeted nutrition and training protocols can close the gap—but only if you know there's a gap to close.
Read insight →Muscle VO2 Max
Capillary density and oxygen extraction in muscle tissue determine how long you can sustain power output before fatigue wins. Higher values mean natural endurance; lower values respond dramatically to specific training protocols that build capillary networks.
Read insight →Overall VO2 Max
Your integrated genetic ceiling for oxygen uptake—heart, lungs, and muscle working together. Everyone has a personal range that's highly trainable, but you can't train what you can't measure. This sets accurate goals and prevents both over-training and leaving potential on the table.

Structure & Resilience
5 insights
Cartilage Support Need
Cartilage maintenance differs markedly from person to person. Some preserve healthy joints for decades of hard use; others show early wear despite doing everything "right." Your profile guides proactive protection—so you're still moving well at 60, not scheduling a knee replacement.
Read insight →Lumbar Disc Support Need
Collagen quality and hydration capacity in your spinal discs vary widely. Higher vulnerability benefits from early core stability work and movement mechanics—often preventing the "one wrong bend" injury that sidelines people for months. This is the kind of thing you want to know before it happens.
Read insight →Rotator Cuff Support Need
Collagen structure and tendon integrity in the shoulder vary widely. Higher-risk individuals benefit from prehabilitation long before pain appears—because shoulder injuries are much easier to prevent than to fix.
Read insight →Tendon and Ligament Support Need
Connective-tissue collagen and repair capacity vary. If you're on the vulnerable side, proactive eccentric loading and targeted nutrition can dramatically reduce sprain and strain risk—before you become the person who "always seems to get injured."
Read insight →Bone Density Support Need
Peak bone density and lifelong resilience are genetically determined. Some people naturally build dense, fracture-resistant bone with minimal effort. Others benefit from earlier, targeted loading and nutrition to reach the same strength, and knowing which camp you're in determines whether you can coast or need to be proactive.

Power & Endurance
3 insights
Endurance Performance
Slow-twitch fiber proportion and mitochondrial density largely determine how long you can sustain effort before the wheels come off. Aligning training and sport choice with your natural profile accelerates progress and eliminates the frustration of fighting your own physiology.
Read insight →Power Performance
Fast-twitch fiber percentage and neural firing rate determine explosive strength—how quickly you can generate force in a sprint, jump, or lift. Understanding your bias toward power or endurance lets you emphasize the right training instead of forcing square pegs into round holes.
Read insight →Power vs Endurance Predisposition
Your muscle-fiber distribution has already voted. Training in harmony with the majority vote produces faster, more enjoyable gains. Fighting it just produces frustration and slower progress.

Strength Building & Recovery
5 insights
Muscle Growth (Hypertrophy) Rate
Some people put on muscle after looking at a dumbbell; others grind for months to see change. The difference is satellite-cell activity and protein-synthesis response—both genetic. Knowing yours sets realistic expectations and points to the volume and recovery approach that actually works for your body.
Read insight →Strength Building Capacity
Neural adaptations and motor-unit recruitment efficiency differ between people. Some get markedly stronger without gaining size; others need higher volume to see the bar move. Your result makes programming precise instead of borrowed from someone else's genetics.
Read insight →Rate of Muscle Fatigue
How quickly your muscles tire depends on lactate clearance and inflammatory response—both genetic. This optimizes your work-to-rest ratios and session design, so you're pushing hard enough to grow without burning out before the work is done.
Read insight →Recovery Speed
Genetic variation in inflammation resolution and protein synthesis governs how long you truly need between hard sessions. Some people rebound in 24 hours; others need 48–72. Training frequency finally makes sense when you stop guessing and start matching.
Read insight →Nitric Oxide Needs
Nitric oxide opens blood vessels, lowers blood pressure, and fuels performance. Some people produce plenty on their own; others run low and don't know it. Lower producers often see dramatic benefits from beetroot, leafy greens, or targeted supplementation—it's one of the easiest performance wins available.
