The Longevity Ceiling
The Risk Profile: VO2 Max is a primary predictor of healthspan. Moving from the "Low" category to "Above Average" can reduce all-cause mortality risk by nearly 50%.
Functional Headroom: Building a high ceiling at 50+ provides the cardiovascular "buffer" needed to maintain high mobility and cognitive function into your late 80s.
Lab Protocol: Training Cadence
01. Intensity Split
Prioritize 80% Zone 2 training (low intensity) to build mitochondrial density without overtaxing joints.
02. Measurement
For masters athletes, heart rate variability (HRV) should guide interval sessions to prevent overtraining.
03. Verification
Retest every 12 weeks. VO2 is a trailing indicator of cardiovascular resilience.
