METs (Metabolic Equivalents)

METs (Metabolic Equivalents) are a standardized way to measure the energy cost of physical activities. One MET represents the amount of oxygen your body uses while sitting quietly at rest, which equals approximately 3.5 milliliters of oxygen per kilogram of body weight per minute. According to research published in Bone & Joint Research, METs provide a useful metric for comparing high-functioning individuals and capturing additional health benefits beyond conventional measures.

Scientific Foundation

The concept of metabolic equivalents was first introduced in exercise testing and prescription. Foundational research published in Clinical Cardiology established METs as a reliable method for evaluating functional capacity and prescribing exercise intensity. The system allows healthcare professionals and fitness experts to standardize activity recommendations across different populations and fitness levels.

Clinical Applications

METs are extensively used in clinical settings for cardiac rehabilitation, fitness assessments, and health monitoring. The standardized nature of MET values allows for consistent evaluation of physical activity levels and energy expenditure across diverse populations, making them invaluable for both research and practical applications in healthcare and fitness.

Compendium of Physical Activities

Our calculator uses MET values from the official Compendium of Physical Activities, a comprehensive research database that provides standardized MET values for hundreds of activities. This ensures accuracy and consistency with scientific literature and clinical practice guidelines used worldwide by exercise physiologists and health professionals.

METs Calculation Formulas & Scientific Basis

Basic MET Definition
Standard Definition:
1 MET = 3.5 ml O₂/kg/min
Energy Equivalent:
1 MET = 1 kcal/kg/hour
Based on oxygen consumption at rest for a 70kg, 40-year-old male
Calorie Calculation Formula
Calories per Minute:
Calories/min = (METs × 3.5 × Weight in kg) ÷ 200
Total Calories:
Total Calories = Calories/min × Duration (minutes)
This formula accounts for individual body weight and activity duration
MET-Minutes Calculation
MET-Minutes:
MET-Minutes = MET Value × Duration (minutes)
Weekly Goal:
Recommended: ≥500 MET-minutes per week
MET-minutes provide a standardized measure of total physical activity volume

Physical Activity Intensity Classifications

Intensity Level MET Range Example Activities Health Benefits Target Population
Sedentary ≤ 1.5 METs Sleeping, sitting, lying down Rest and recovery All populations
Light Intensity 1.6 – 2.9 METs Slow walking, light housework, desk work Basic daily function, minimal cardiovascular benefit Sedentary individuals, rehabilitation
Moderate Intensity 3.0 – 5.9 METs Brisk walking, recreational cycling, dancing Cardiovascular health, weight management General population, health maintenance
Vigorous Intensity 6.0 – 8.9 METs Jogging, competitive sports, circuit training Enhanced fitness, performance improvement Active individuals, athletes
Very Vigorous ≥ 9.0 METs Running, competitive cycling, intense sports Elite fitness, athletic performance Athletes, highly trained individuals

Health Benefits & Physical Activity Guidelines

🏃 Cardiovascular Health Benefits

Moderate Intensity (3-6 METs): Aim for 150 minutes per week (500-750 MET-minutes)
Vigorous Intensity (≥6 METs): Aim for 75 minutes per week (450+ MET-minutes)
Combined Approach: Mix moderate and vigorous activities for optimal cardiovascular benefits
Research shows that achieving 500+ MET-minutes per week significantly reduces cardiovascular disease risk.

💪 Weight Management Applications

Weight Loss: Target 1,500-2,000 MET-minutes per week for significant weight loss
Weight Maintenance: 500-1,000 MET-minutes per week helps maintain healthy weight
Calorie Balance: Use MET calculations to balance energy intake and expenditure
Higher intensity activities (≥6 METs) provide greater calorie burn per unit of time.

🧠 Mental Health & Cognitive Benefits

Stress Reduction: Moderate activities (3-6 METs) effectively reduce stress hormones
Mood Enhancement: Regular activity at 4+ METs improves mood and reduces depression
Cognitive Function: Activities ≥3 METs support brain health and memory
Even light activities (1.6-2.9 METs) provide mental health benefits for sedentary individuals.

Limitations & Considerations

While METs provide valuable standardized measurements, several factors should be considered for accurate interpretation:

  • Individual Variation: Actual energy expenditure varies based on age, fitness level, body composition, and genetics
  • Environmental Factors: Temperature, humidity, altitude, and terrain affect actual MET values
  • Exercise Efficiency: Trained individuals may have lower energy costs for the same activities
  • Body Weight Considerations: Standard formulas may be less accurate for very light or heavy individuals
  • Activity Specifics: Intensity within the same activity can vary significantly (e.g., recreational vs. competitive cycling)
  • Health Status: Medical conditions, medications, and fitness level affect metabolic responses
  • Measurement Accuracy: Self-reported activity levels may not always reflect actual intensity
  • Cultural Differences: Activity patterns and intensities may vary across different populations

Important Note: Use MET calculations as estimates for planning and comparison purposes. Individual responses to exercise can vary significantly. Always consider personal factors, health status, and consult with healthcare professionals for personalized exercise recommendations, especially if you have pre-existing health conditions or are new to exercise.
