The formula to calculate the Critical Swim Speed is:
\[ CSS = \left(\frac{D}{T}\right) \times 100 \]
Where:
Critical Swim Speed (CSS) is a concept used in swimming training to determine the maximum speed a swimmer can maintain over a prolonged period of time without fatigue. It is often used as a benchmark for designing training programs and gauging progress. CSS is typically calculated based on the time it takes a swimmer to complete two different distances, usually 200 meters and 400 meters. The difference in speed between these two distances is used to estimate the swimmer’s lactate threshold, or the point at which lactic acid begins to accumulate in the muscles faster than it can be removed, leading to fatigue. By training at or near their CSS, swimmers can improve their endurance and overall speed.
Example 1:
Step 1: Calculate the Critical Swim Speed:
\[ CSS = \left(\frac{200}{120}\right) \times 100 \approx 166.67 \text{ meters per minute} \]
Example 2:
Step 1: Calculate the Critical Swim Speed:
\[ CSS = \left(\frac{400}{300}\right) \times 100 \approx 133.33 \text{ meters per minute} \]
