Mitochondrial Health Quiz
Quiz
What master regulator of mitochondrial biogenesis does Zone 2 training activate?
From the Zone 2 lesson.
PGC-1α — peroxisome proliferator-activated receptor gamma coactivator 1-alpha — is the master regulator of mitochondrial biogenesis. Zone 2 work upregulates PGC-1α expression, telling cells to manufacture more mitochondria.
Quiz
Approximately how much do mitochondria decline per year in untrained adults after 30?
From the decline lesson.
About 1% per year, or ~10% per decade — but this is highly modifiable. Trained 70-year-olds often have better mitochondrial function than untrained 30-year-olds.
Quiz
In the Finnish FINSAUNA study, regular sauna use (4+ sessions/week) was associated with…
Long-term cohort outcome.
~40% lower all-cause mortality at 4+ sessions per week, 20+ minutes at 80°C+. One of the strongest non-exercise mortality-reduction signals in the literature.
Quiz
Which supplement has the strongest 2023 evidence as a longevity-relevant deficiency to correct?
Based on the Science paper covered.
Taurine — the 2023 Science paper showed levels fall ~80% by age 60 in humans, and supplementation extended mouse lifespan by 10–12%. Cheap, safe, and a low-downside experimental addition for adults over 40.
