VO2 Maxxing Gains Traction as 750,000-Person Study Links Fitness to Longer Life

3 articles · Updated · The Times of India · Aug 19

Summary

  • VO2 maxxing is drawing fitness enthusiasts to chase maximal oxygen consumption as a shorthand for cardiorespiratory fitness and longevity, with smartwatch scores helping fuel the trend.
  • More than 750,000 U.S. veterans in one study showed an inverse, graded link between fitness and mortality, with the least-fit group facing about 4 times the death risk of the extremely fit.
  • A separate 5,107-man study with up to 46 years of follow-up found the highest midlife fitness group had nearly 5 extra years of life expectancy versus the lowest group.
  • 150 minutes of moderate exercise or 75 minutes of vigorous activity a week can help raise VO2 max, while HIIT can accelerate gains without requiring all-out daily training.
  • Wearables from Apple or Garmin only estimate VO2 max, and experts caution that age, sex, genetics and body composition all affect the score, making it a useful marker rather than a magic number.
