SUMMARY
The discussion focuses on calculating the metabolic energy expenditure for a 68 kg individual running at 15 km/h for 12 minutes and walking at 5.0 km/h for 36 minutes. Key equations include E=W (+Q), W=FD, and e=1/2 mv^2. A participant noted that running at 15 km/h requires approximately 1150 W of metabolic power, emphasizing the need for accurate unit conversions and formulas to derive energy in kilojoules. The conversation highlights the complexities of estimating energy expenditure due to factors like body elevation and limb mass.
