Question Is it possible to be diagnosed with heart failure and still row 6 km in 60 minutes, 1000 m in 8 minutes, and 500 m in 3.5 minutes?
Answer Yes — if heart failure is mild or well-controlled (NYHA I–II), those rowing results are plausible. They are unlikely in NYHA III–IV.

NYHA Functional Classes
| Class | Definition | Rowing Fit (6k/60′, 1k/8′, 500m/3.5′) |
|---|---|---|
| I — No limitation | Ordinary activity doesn’t cause undue symptoms. | ✔️ Very likely achievable. |
| II — Mild limitation | Symptoms with ordinary activity; comfortable at rest. | ✔️ Likely achievable with pacing. |
| III — Marked limitation | Symptoms with less-than-ordinary activity. | ❌ Unlikely, not typical. |
| IV — Severe limitation | Symptoms at rest. | ❌ Not feasible. |
Estimated METs & VO₂
| Performance | Pace | Estimated METs | Approx. VO₂ (ml/kg/min) |
|---|---|---|---|
| 6 km in 60 min | ~2:30/500m | 5–6 | 17–21 |
| 1000 m in 8 min | ~4:00/500m | 3–4 | 10–14 |
| 500 m in 3.5 min | ~3:30/500m | 5–7 | 17–24 |
Context: Healthy adults often reach 30–40 ml/kg/min (8–11 METs). Many NYHA I–II patients have VO₂peak ≈ 15–25 ml/kg/min (4–7 METs). NYHA III–IV is typically <14 ml/kg/min (<4 METs).
Clinical Notes
- “Heart failure” is a spectrum of pump dysfunction; many people with mild HF can exercise.
- Individualize with cardiopulmonary exercise testing (CPET) when available.
- Consult your cardiologist/electrophysiologist for personalized training and safety.
