Key Takeaways
- Aquatic cycling (hydro-cycling) uses water resistance instead of mechanical resistance, with estimated MET values of 5.5–9.0 depending on intensity.[1]
- Research by Dong et al. (2022) showed VO2 of aqua cycling ranges from 14–30 ml/kg/min across intensities — comparable to moderate land cycling.[2]
- Water buoyancy reduces joint impact while water resistance provides a full lower-body workout.
How the Calculation Works
The MET formula applies: Calories = MET × body weight (kg) × time (hours). The base MET is adjusted by a water resistance multiplier (0.9× for low, 1.0× for medium, 1.15× for high).[1]
For land-based cycling estimates, see the Cycling Calorie Calculator. For other aquatic activities, try the Aquathlon Calculator.
Limitations and Important Notes
- Aquatic cycling MET values are less well-established than land-based activities and vary significantly by equipment design.[3]
- Water temperature, pool depth, and pedaling technique all affect actual energy expenditure.
