How much work capacity is lost at 2% dehydration?

When the body experiences dehydration, it impacts physical performance and work capacity. At a dehydration level of 2%, research indicates that the loss of work capacity can range significantly, but it is generally acknowledged to cause a drop of approximately 1-3% in performance. At a 2% level of dehydration, the body begins to show subtle signs of impaired function, which can affect endurance, strength, and overall performance without leading to severe impairment.

For a dehydration level of 5-8%, the decline in work capacity becomes much more pronounced, with notable declines in muscle endurance and other performance metrics. A dehydrated state of around 12-15% can lead to serious physiological issues while levels greater than that can be life-threatening.

Therefore, the answer that reflects the correct work capacity loss due to a 2% dehydration level corresponds with the range that indicates a slight drop in performance, making the range of 1-3% the correct response.
