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.
What this measures
How your DNA shapes cardiovascular VO2 max.
VO2 max — the maximum rate your body can use oxygen during exercise — is shaped by the genes that govern mitochondrial biogenesis, the process of building new mitochondria in response to training stress. PPARGC1A is the master regulator; NRF1 and NRF2 work downstream to activate the genes that build the new machinery.
Carriers of favorable variants in these genes are associated with faster adaptation to endurance training — VO2 max improvements that match the training volume. Carriers of less-favorable variants tend to need more total volume, longer training cycles, or different intensity distribution to see the same gains. Neither path is a ceiling; both reach high VO2 max with the right inputs.
Mitochondrial biogenesis is driven by training stress, fasting, cold exposure, and specific nutrients (CoQ10, PQQ, B vitamins). Polyphenols (resveratrol, EGCG) activate the same pathway. Sleep recovery is when most of the actual building happens — under-recovered training stalls the adaptation regardless of the variant.
Two people on the same training program won’t see the same VO2 max improvement — and now you know one of the reasons why. Your variant doesn’t cap your ceiling; it shapes which inputs move the needle for you specifically.
Cardiovascular VO2 Max is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the athletic performance spectrum — and what you can do about it: it renders as a dark card with a color marker calibrated to your variants, opening with the gene mechanism and closing with a practical, mechanism-led recommendation.

Aerobic Capacity (VO₂ Max): the 4-insight cluster.
Cardiovascular VO2 Max is one finding in a tightly-related cluster. Mosaic sequences the other 3 alongside it so you see the whole biology — not an isolated data point.

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.
Read insight →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 →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 →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 →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 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.
