参考答案: The climber does the same amount of work whether climbing straight up or via a zigzag path, ignoring dissipative forces. But if a longer zigzag path is taken, it takes more time to do the work, and so the power output needed from the climber is less. That will make the climb easier. It is easier for the human body to generate a small amount of power for long periods of time rather than to generate a large power for a small period of time.
