How Samsung Health Calculates Calories Burned: A Comprehensive Guide

Samsung Health is a powerful tool designed to help users track and manage their health and fitness. One of its key features is calculating the calories burned during various activities. This process involves a complex interplay of user data, activity tracking, heart rate monitoring, and metabolic equivalent of task (MET) values. In this article, we will delve into the intricacies of how Samsung Health calculates these calories burned.

User Profile Information

At the foundation of Samsung Health's calorie burn calculations are detailed profiles that include personal data such as age, weight, height, gender, and fitness level. This information is crucial as it helps establish a baseline for two important metrics: basal metabolic rate (BMR) and total daily energy expenditure (TDEE).

Basal Metabolic Rate (BMR): This represents the number of calories your body burns at rest to sustain vital functions like breathing and circulation. BMR varies based on age, sex, weight, and height. Total Daily Energy Expenditure (TDEE): This is the total energy (caloric) expenditure in a 24-hour period. TDEE takes into account BMR, plus the energy used for physical activity and the thermic effect of food.

Activity Tracking

Central to Samsung Health's functionality is real-time activity tracking. This involves the use of sensors in your smartphone or connected wearable devices like smartwatches. The app collects data on a wide range of physical activities, including:

Steps taken Distance traveled Specific workouts: running, cycling, etc.

Heart Rate Monitoring

For users with devices that support heart rate monitoring, Samsung Health goes the extra mile by incorporating heart rate data. This can provide more accurate calorie burn estimates, especially during intense workouts. Higher heart rates typically signal a higher caloric expenditure, as the body must work harder to maintain basic functions.

MET Values

The app utilizes MET (Metabolic Equivalent of Task) values to estimate calorie burn for different activities. MET values represent the energy cost of physical activities as a multiple of the resting metabolic rate. For example, running typically has a higher MET value than walking, indicating it burns more calories per minute.

Duration and Intensity of Activity

The duration and intensity of physical activities are critical factors in calorie burn calculations. Longer and more intense workouts generally lead to higher caloric expenditure. Samsung Health takes this into account to provide a more accurate estimate of the calories burned during specific activities.

The formula used within the app for estimating calories burned is:

Calories Burned MET times; Weight (kg) times; Time (hours)

Daily Activity Level

In addition to the detailed activity tracking mentioned above, Samsung Health considers your overall daily activity level. This includes movements that might not be formally classified as exercise, such as standing, light walking, and fidgeting.

By integrating these various data points, Samsung Health aims to provide a comprehensive estimate of calories burned throughout the day. This helps users monitor their fitness and health goals more effectively.

Conclusion

Samsung Health's approach to calculating calories burned is sophisticated and multi-layered. By taking into account a wide range of factors, from user profiles to activity intensity and heart rate data, the app offers a personalized and accurate estimation of daily caloric expenditure. Whether you are tracking your fitness goals or simply staying informed, Samsung Health provides valuable insights to help you stay on track.
