VO2max in swimming
Technique first, then the engine. VO2max in swimming: why values measured in water are lower than on land, how technique dominates, and the aerobic sets that work.
VO2max by level
Swimming VO2max is usually measured lower than running VO2max in the same person: less muscle mass works and the body is horizontal.
Data table
| Level | Men | Women |
|---|---|---|
| Untrained adults | 35–45 | 30–38 |
| Fitness swimmers | 42–50 | 36–44 |
| Competitive | 50–62 | 44–54 |
| Elite | 60–75 | 50–65 |
What the sport demands
Our rating, 1–5Why VO2max matters in swimming
Swimming is a skill sport: drag reduction and propulsion matter more than raw VO2max for most swimmers.
Aerobic fitness still matters from the 200 m upward — and for open-water and triathlon swimmers above all.
Sessions that raise it
Aerobic 100s
10–20 × 100 m at a steady pace, 10–15 s rest.
VO2 set
6–8 × 200 m hard, 30–45 s rest.
Technique
Drills every session — the biggest win for most adults.
General information, not medical advice. Get medical advice before hard intervals if you have a heart condition or symptoms such as chest pain.
Estimate your own number with the VO2max calculator and compare it with the norms for your age.
