Which individual would likely experience the greatest difficulty when performing at high altitudes________?
Show answer Hide answer
Answer: C. marathon
Explanation
Marathon runners rely heavily on aerobic endurance, making them experience the greatest difficulty at high altitudes due to lower oxygen partial pressure. High-altitude environments feature reduced atmospheric pressure, which decreases the amount of oxygen available with each breath. Endurance athletes depend entirely on continuous oxygen transport to working muscles, making altitude drops devastating to pace. Altitude sickness and hypoxia affect athletes differently depending on the metabolic energy systems required by their sport. Events lasting several hours rely heavily on the aerobic system, whereas short sprints depend on anaerobic pathways. Training at high altitudes stimulates red blood cell production over time, but acute exposure severely impairs performance.
Option A is incorrect because long jump is a brief explosive event relying on anaerobic power. Option B suggests the four hundred meters, which is a sprint relying mostly on anaerobic glycolysis. Option D is wrong because marathon running clearly experiences the greatest altitude difficulty.
