Hedging — Quiz

Test your understanding of hedging with 5 practice questions.

Practice Questions

Question 1

During steady‐state exercise an athlete has a metabolic heat production of 900 W, performs external work of 150 W, and loses 500 W by evaporation. What is the combined rate of dry heat loss (radiation + convection + conduction) in watts?

Question 2

Assuming no heat loss, how long would it take for a 60 kg athlete with specific heat capacity of 3470 J/(kg⋅°C) to increase core temperature by 1 °C if net heat storage is 100 W?

Question 3

After heat acclimation plasma volume increases by 12%. If an athlete’s initial plasma volume is 2.8 L, what is the new plasma volume?

Question 4

Calculate the Wet‐Bulb Globe Temperature (WBGT) using WBGT = 0.7·Tw + 0.2·Tg + 0.1·Ta for Ta = 32 °C, Tw = 27 °C, Tg = 40 °C.

Question 5

What is the SI unit equivalent of 1 clo in thermal insulation?
