The Science Behind the Energy Expenditure during Long-Distance Running

When engaging in extended physical activities such as long-distance running, our bodies undergo numerous complex processes to provide the necessary energy and sustain our performance. Understanding the science behind the calorie burning during running can give us valuable insights into the physiological mechanisms at play.

During endurance activities, the body requires a substantial amount of fuel to meet the increased energy demands. This fuel primarily comes from the breakdown of stored carbohydrates and fats, which are converted into usable energy through metabolic processes. As each individual has a unique metabolism and fitness level, the exact caloric expenditure can vary significantly.

One crucial factor that determines the energy expenditure during running is the intensity at which the activity is performed. Higher intensity levels, such as those experienced during sprinting or high-intensity interval training (HIIT), require more energy and result in a greater caloric burn compared to moderate or low-intensity running. Additionally, factors like body weight, age, gender, and running efficiency can also influence the calorie expenditure during running.

A useful way to estimate the energy expenditure during long-distance running is through the concept of metabolic equivalent of task (MET). MET represents the ratio of the energy expended during a specific activity to the energy expended at rest. Running typically has a MET value between 8 and 15, depending on the speed and terrain. By multiplying the MET value with the individual’s body weight in kilograms, we can estimate the calories burned per hour.

Running Speed (MET) Calories Burned per Hour (Based on 150 lbs)
6 510
8 680
10 850
12 1020
15 1275

It is essential to note that these estimations are just approximations, and individual variations may exist. Furthermore, long-distance running at extreme distances, such as 100 miles, introduces additional factors, including fatigue, muscle damage, and nutritional strategies, which significantly impact the overall energy expenditure.
