Prolonged Exercise Results in a Significant Increase in Body Core $\degree$

Multiple Choice

Prolonged exercise results in a significant increase in body core temperature.Calculate the increase in body core temperature during exercise given the following: Total energy expenditure during exercise = 600 Kcal
Exercise efficiency = 20%
Total heat stored during exercise = 192 Kcal
Subject body weight = 60 Kg
Amount of heat required to increase body temperature by 1 $\degree$ C = 0.83 kcal/kg
Therefore,the total increase in body temperature following exercise would be:

A) 1.86 $\degree$ C
B) 2.86 $\degree$ C
C) 3.86 $\degree$ C
D) 4.86 $\degree$ C
