The men’s 800-meter world record holder, David Rudisha, set his record on August 9, 2012, at the London Olympics. His record time was 1 minute 40.91 seconds.

• Weight = 76 kg
• Height = 1.88 meters (6.2 feet)

MET (Metabolic Equivalent of Task)

MET is used to estimate how many calories are burned during an activity.

Running 800 meters at such a high speed is an extremely high-intensity activity.

• The MET value for running at this speed is approximately 15.
• Based on Rudisha’s weight (76 kg) and race duration (1.68 minutes or 40.91 seconds), the energy expenditure can be estimated.

Calorie Burn Estimation for Running 800 Meters

A person weighing 70 kg would take approximately 1 minute and 82.14 seconds to complete an 800-meter race if they are expending 34 calories at 16 MET.

Time Calculation

The energy (calories) required to complete an 800-meter race in 2 minutes depends on various factors such as body weight, physical fitness, running intensity, and energy efficiency. However, an estimated calculation is as follows:

Estimated Calories Burned for Different Weights:

Weight (kg)	Calories Burned (kcal)
50	50.6
60	60.7
70	70.9
80	81
90	91.1

Conclusion

• A heavier person burns more calories than a lighter person while running the same distance.
• On average, running 1500 meters at high speed in 4 minutes burns between 50 to 100 calories, depending on the runner’s weight and fitness level.
• Time, temperature, and external conditions also significantly affect calorie expenditure and energy utilization.
