What this is

Mandsager 2018 JAMA Network Open: elite CRF associated with 80% reduction in all-cause mortality vs low CRF. Every 1 MET increase in CRF = ~10-15% mortality reduction. Probably the strongest single exercise signal.

Mechanism

Maximal oxygen consumption is strongly inversely correlated with all-cause mortality; HIIT improves VO2 max faster than steady-state; mitochondrial density and cardiac output adaptations

Dose & route

1-2 sessions/week; e.g., Norwegian 4x4 (4 min high / 3 min recovery × 4); Tabata; 30:30 intervals
