1. What is Water Anaerobic Threshold?

The water anaerobic threshold (AT_water) is the exercise intensity at which lactate begins to accumulate in the bloodstream during water-based activities. It's typically lower than land-based anaerobic threshold due to the different physiological demands of aquatic exercise.

2. How Does the Calculator Work?

The calculator uses the water anaerobic threshold equation:

\[ AT_{water} = AT_{land} \times adjustment \]

Where:

Explanation: The equation accounts for the reduced cardiovascular stress in water compared to land-based exercise.

3. Importance of AT Calculation

Details: Knowing your water anaerobic threshold helps in designing effective aquatic training programs and monitoring exercise intensity for optimal results.

4. Using the Calculator

Tips: Enter your land anaerobic threshold in bpm and the appropriate adjustment factor (default is 0.9). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is water AT different from land AT?
A: Water's buoyancy reduces gravitational stress and cooling effects alter cardiovascular responses, typically resulting in a lower AT.

Q2: What's a typical adjustment factor?
A: Most studies use 0.9, but this may vary from 0.85-0.95 depending on individual factors and water temperature.

Q3: How do I measure my land AT?
A: Land AT is typically measured through graded exercise testing with lactate measurement or ventilatory gas analysis.

Q4: Does water temperature affect AT?
A: Yes, colder water may increase AT slightly while warmer water may decrease it due to thermoregulatory demands.

Q5: Should I use this for all water exercises?
A: The adjustment is most accurate for swimming; other aquatic activities may require different adjustments.
