Introduction
When it comes to fat loss, the number of calories burned during exercise is a critical factor to consider. While many people associate sprinting with enhanced athletic performance, it is also important to examine its potential for burning calories and promoting fat loss.
An extremely rough estimate is that one average sprint training session may burn around ~300 calories, however, as we will discuss, multiple variables influence this calculation.
This blog post aims to answer the question, “How many calories can sprinting burn?” by discussing the factors that influence calorie burn during sprinting, comparing it to other forms of exercise, and providing examples of calorie burn estimates. Additionally, we will explore the benefits of sprinting beyond calorie burn and discuss how to incorporate it into a fat loss program.
Factors Affecting Calorie Burn During Sprinting
Obviously, there’s no single answer to the question “How many calories can sprinting burn?”, as multiple variables influence this calculation. Let’s examine these variables before we jump into approximate numerical estimates.
Body weight
Body weight plays a significant role in determining the number of calories burned during any physical activity, including sprinting. Heavier individuals tend to burn more calories due to the increased energy required to move their body mass.
Sprinting speed
The faster you sprint, the more calories you burn. Sprinting at a higher speed requires more energy and muscle engagement, leading to a higher calorie expenditure.
Duration of sprints
The length of your sprints also affects the number of calories burned. Longer sprints will generally result in a higher calorie burn, but it’s essential to balance intensity and duration to maximize the benefits of sprint training while minimizing the risk of injury.
Intensity and rest intervals
The intensity of your sprinting workout and the rest intervals between sprints can also influence the total calorie burn. High-intensity interval training (HIIT) that incorporates short bursts of all-out sprints followed by brief rest periods can be an effective way to burn calories and improve cardiovascular fitness.
Individual metabolism and fitness level
Each person’s metabolism and fitness level can also affect the number of calories burned during sprinting. Those with a faster metabolism or higher fitness level may burn more calories due to their bodies’ increased efficiency in utilising energy. It is essential to consider these individual factors when estimating calorie burn during sprint workouts.
Longer durations and higher intensities lead to more calories burned….unsurprisingly.

Estimating Calorie Burn During Sprinting
General formula for calculating calorie burn
Calculating calorie burn during sprinting can be challenging due to the various factors that influence energy expenditure. However, a general formula can help estimate calorie burn:
Calories burned = (MET value of sprinting) x (body weight in kg) x (duration in hours)
The MET (Metabolic Equivalent of Task) value for sprinting varies depending on the intensity, with values typically ranging from 8 into the 20s.
Comparison with other forms of exercise (jogging, swimming, cycling)
To put sprinting in perspective, let’s compare its calorie-burning potential to other common forms of exercise:
- Jogging (5-7 METs): A lower intensity activity that burns fewer calories per minute compared to sprinting but can be sustained for a longer duration.
- Swimming (7-10 METs): A full-body workout that can burn a significant number of calories depending on the stroke and intensity.
- Cycling (8-15 METs): The calorie burn during cycling depends on factors like speed, terrain, and resistance, with higher-intensity cycling sessions burning more calories.
Examples of calorie burn estimates for sprinting workouts based on distance
Considering track and field sprinting workouts based on distance, here’s an example of a workout and its estimated calorie burn:
- A 75 kg individual performing 10x30m sprints with 2-minute rest intervals between each sprint:
- Assuming a total workout duration of ~20 minutes and a MET value of 12 for intense sprinting: Calories burned ~ 12 x 75 x (20/60) = 300 calories

Benefits of Sprinting Beyond Calorie Burn
While calorie burn is an essential factor in fat loss, sprinting offers several additional benefits that contribute to overall health and fitness:
Boosting metabolism and post-exercise calorie burn
Sprinting, especially when performed as part of a high-intensity interval training (HIIT) workout, can increase your metabolism and promote higher calorie burn even after the exercise session has ended. This phenomenon, known as excess post-exercise oxygen consumption (EPOC), helps burn more calories throughout the day.
Hormonal changes elicited by sprinting
Sprinting stimulates the release of various hormones, such as human growth hormone (HGH) and testosterone, which play a role in muscle growth, recovery, and fat metabolism. These hormonal changes can contribute to fat loss and muscle development, further enhancing the overall benefits of sprinting.
Building lean muscle mass
Sprinting engages multiple muscle groups, including the glutes, hamstrings, quadriceps, and calves, leading to the development of lean muscle mass. Increased muscle mass can enhance your metabolic rate, enabling you to burn more calories at rest.
Enhancing athletic performance and explosivity
Sprinting is known for improving athletic performance by increasing speed, power, and agility (that’s kind of what this whole website is about…). Incorporating sprint training into your exercise routine can help you develop the explosivity needed for various sports and activities.
How To Incorporate Sprinting Into a Fat Loss Program
A successful fat loss program combines a balanced diet, regular exercise, and a healthy lifestyle. Sprinting can be an effective component of your exercise routine to help burn calories and enhance overall fitness. Here’s how to incorporate sprinting into your fat loss program:
Although sprinting has several benefits, I assume that if you’re reading this article then you’re mostly interested in how sprinting can help you burn fat. Some guidelines are listed below.
Designing a sprinting workout
Warm-up and cooldown: Start each sprinting session with a 5-10 minute dynamic warm-up, including activities like jogging, high knees, and leg swings. With sprinting being such a high-intensity activity, a proper warm up is crucial.
Sprint intervals and rest periods: Design your sprinting workout by alternating between sprinting and resting intervals. Start of with lesser distances and longer rest periods, and increase the intensity over time.
Progression and variety in workouts: Gradually increase the intensity, duration, or frequency of your sprint workouts as you become more comfortable with the exercise. Incorporate different sprinting variations, such as hill sprints or sprinting with resistance, to challenge your body and maintain interest.
Balancing sprinting with other forms of exercise
While sprinting is a powerful tool for fat loss, it is important to balance it with other forms of exercise to ensure a well-rounded fitness program.
Incorporate strength training and other forms of cardiovascular activities, such as jogging or swimming, to complement your sprint training (if your goal is primarily to modify body composition/lose fat).
Importance of a healthy diet and lifestyle
Sprinting alone cannot guarantee fat loss; it must be paired with a healthy diet and lifestyle. This goes without saying but must be mentioned briefly here anyway. Also, prioritize sleep, stress management, and staying hydrated to support your fat loss goals.
Conclusion
Sprinting is a powerful and versatile form of exercise that can contribute significantly to fat loss and overall fitness. Calorie burn during sprinting depends on various factors, including body weight, sprinting speed, duration, intensity, and individual metabolism.
In addition to calorie burn, sprinting offers numerous benefits such as boosting metabolism, building lean muscle mass and enhancing athletic performance.
Incorporating sprinting into your exercise routine can provide a challenging and effective workout that contributes to fat loss while offering additional health benefits. Design a sprinting workout that suits your fitness level and goals, balancing it with other forms of exercise and a healthy diet to maximize results.
