Frequently Asked Questions — VO2 Max Calculator
How does VO2 Max change with age?+
VO2 Max declines approximately 1% per year after age 25 in sedentary people. Regular endurance exercise can slow this to 0.5% per year. Highly trained athletes in their 50s often have higher VO2 Max than sedentary 30-year-olds.
What is a good VO2 Max for a 40-year-old?+
ACSM standards for 40-49 year olds: Poor <36 mL/kg/min, Fair 36-42, Good 43-48, Excellent 49-54, Superior >54 (male). Women: approximately 5 mL/kg/min lower in each category.
Can you improve VO2 Max after 50?+
Yes — several studies show even sedentary adults in their 60s-70s can improve VO2 Max by 10-15% through regular aerobic exercise. HIIT is particularly effective at any age. Consistency for 12+ weeks is essential.
