The question lacks the multiple options. The options are as follows:
A. After 1 hour of moderate-intensity exercise (60% to 85% VO2 max), when blood glucose levels dwindle
B. After 1 to 3 hours of continuous moderate-intensity exercise (60% to 85% VO2 max), when glycogen becomes depleted
C. After 5 to 6 hours of continuous low-intensity (50% to 60% VO2 max), when blood glucose levels dwindle
D. After 30 minutes of continuous high-intensity (70% to 90% VO2 max), when glycogen becomes depleted
Answer:
Option (B).
Explanation:
Glucose is the monosaccharide and the single momoneric unit and when repeated again and again can leads to the formation of polymer. The glucose acts as the primary source of the energy.
The glucose is breakdown to form the ATP. The glucose is continuously used in the exercises. If the glucose is not taken, the individual be only able to perform the moderate exercise only for 1-3 hours. The individual feels fatigue and needs rest if glucose consumption is decreases in the body.
Thus, the correct answer is option (B).
