SUMMARY
The energy expenditure for a 60 kg person climbing stairs to a height of 25 meters can be calculated using the formula Wg = mgh, resulting in an energy requirement of 14,715 Joules. However, considering the muscle efficiency of approximately 20%, the actual energy input required would be significantly higher. This discussion emphasizes the importance of understanding both the work output and the energy input when calculating physical exertion in activities such as stair climbing.
