Background & Theory
The Met Minutes applies the following established principles and formulas. Sports statistics and performance metrics represent one of the most data-rich domains of applied mathematics available to the general public. Baseball, in particular, has developed an exceptionally dense vocabulary of calculated metrics. Earned run average (ERA) quantifies a pitcher's effectiveness as (earned runs × 9) / innings pitched, normalising performance to a nine-inning standard regardless of how many complete games were pitched. WHIP, or walks and hits per inning pitched, is computed as (walks + hits) / innings pitched and provides a complementary measure of how frequently a pitcher allows baserunners. Batting average, one of the oldest statistics in the sport, is simply hits / at-bats, though more modern metrics such as on-base percentage and slugging percentage have largely supplanted it as primary performance indicators. The NFL passer rating formula is considerably more complex, combining completion percentage, yards per attempt, touchdown rate, and interception rate into a composite score scaled to a 0–158.3 range. Golf handicap calculation, now governed by the World Handicap System introduced in 2020, uses a Handicap Differential formula applied to the best 8 of a player's most recent 20 score differentials, with adjustments for course rating and slope. The Elo rating system, originally developed by physicist Arpad Elo for chess ranking in the 1960s, has become a widely adopted framework for competitive ranking in sports ranging from football to table tennis. It updates each player's rating after every match based on the margin of expected versus actual result. In endurance sports, pace calculation converts total time to a per-mile or per-kilometre rate, informing training intensity and race strategy. In cycling, power-to-weight ratio (watts per kilogram) is the primary determinant of climbing performance and is central to both professional race analysis and amateur fitness tracking. Fantasy sports scoring systems synthesise multiple individual statistics into aggregate point totals, requiring participants to understand the relative value of different performance categories across sports.
History
The history behind the Met Minutes traces back through the following developments. Organised athletic competition has roots extending to ancient Greece, where the Olympic Games were held at Olympia beginning around 776 BCE. These early games were embedded in religious observance and civic identity, featuring events such as sprinting, wrestling, and the pentathlon. The codification of modern sport rules accelerated dramatically in 19th century Britain, where industrialisation created both the leisure time and the institutional infrastructure for organised competition. The Football Association formalised the rules of association football in 1863, and similar governing bodies for cricket, rugby, tennis, and athletics followed in subsequent decades. Pierre de Coubertin, a French educator inspired by the English model of sport as character-building, campaigned to revive the Olympic Games as a modern international institution. The first modern Summer Olympics were held in Athens in 1896, establishing the template for international multi-sport competition that has continued to the present. FIFA, the international governing body for association football, was founded in Paris in 1904 with seven member nations. The serious statistical analysis of baseball, later termed sabermetrics, was pioneered by writers and analysts including Bill James beginning in the late 1970s. James self-published his Baseball Abstract annuals starting in 1977, introducing rigorous empirical methods to a domain previously dominated by traditional counting statistics and subjective scouting. His work influenced a generation of analysts and front-office executives. The publication of Michael Lewis's Moneyball in 2003, documenting the Oakland Athletics' 2002 season and their use of on-base percentage and other undervalued metrics, brought sports analytics to mainstream attention. The subsequent analytics revolution reshaped hiring practices and game strategy across professional sports leagues. Fantasy sports, which require participants to engage directly with statistical outputs, grew from a hobby practised by a few thousand enthusiasts in the 1980s into a multi-billion dollar industry by the 2010s, with tens of millions of participants across football, baseball, basketball, and other sports.

Formula
MET-minutes = MET value x Duration (minutes)
Where MET value represents the metabolic equivalent of the activity (1 MET = resting metabolic rate of 3.5 mL O2/kg/min), and Duration is the time spent performing the activity in minutes. To convert to calories: Calories = MET x body weight (kg) x duration (hours). The WHO recommends 500-1000 MET-minutes per week for optimal health benefits.
Worked Examples
Example 1: Weekly Running Program
Problem: A 75 kg person runs at 8 METs for 45 minutes, 4 times per week. Calculate their weekly MET-minutes and calorie expenditure.
Solution: MET-minutes per session = 8 METs x 45 min = 360 MET-minutes\nWeekly MET-minutes = 360 x 4 = 1,440 MET-minutes\nCalories per session = 8 x 75 kg x (45/60 hr) = 450 calories\nWeekly calories = 450 x 4 = 1,800 calories\nWHO minimum (500) met: 288%\nWHO optimal (1000) met: 144%
Result: 1,440 weekly MET-minutes | 1,800 weekly calories | Exceeds WHO optimal guidelines by 44%
Example 2: Mixed Activity Week
Problem: A 65 kg person does yoga (2.5 METs, 60 min, 2x), brisk walking (4 METs, 30 min, 3x), and cycling (7 METs, 40 min, 2x). Calculate total weekly MET-minutes.
Solution: Yoga: 2.5 x 60 = 150 MET-min x 2 = 300 MET-minutes\nBrisk walking: 4 x 30 = 120 MET-min x 3 = 360 MET-minutes\nCycling: 7 x 40 = 280 MET-min x 2 = 560 MET-minutes\nTotal weekly MET-minutes = 300 + 360 + 560 = 1,220\nTotal weekly calories = (2.5x65x1 x2) + (4x65x0.5 x3) + (7x65x0.667 x2) = 325 + 390 + 607 = 1,322 cal
Result: 1,220 weekly MET-minutes | 1,322 weekly calories | Exceeds WHO optimal by 22%
Frequently Asked Questions
What are MET-minutes and why are they important?
MET-minutes are a standardized way to quantify the total energy expenditure of physical activity by combining both intensity and duration into a single metric. One MET (Metabolic Equivalent of Task) represents the energy cost of sitting quietly, approximately 3.5 milliliters of oxygen consumed per kilogram of body weight per minute. MET-minutes are calculated by multiplying the MET value of an activity by its duration in minutes. For example, walking briskly (3.5 METs) for 30 minutes yields 105 MET-minutes. This metric is used extensively in epidemiological research and public health guidelines because it allows researchers to compare the health benefits of different activities regardless of their type or intensity.
What is the WHO recommendation for weekly MET-minutes?
The World Health Organization recommends that adults accumulate at least 150-300 minutes of moderate-intensity aerobic activity per week, which translates to approximately 500-1000 MET-minutes per week. Achieving the lower threshold of 500 MET-minutes per week is associated with significant reductions in all-cause mortality, cardiovascular disease, type 2 diabetes, and several cancers. Reaching the higher target of 1000 MET-minutes provides additional health benefits with dose-response improvements in health outcomes. Research published in The Lancet has shown that individuals exceeding 3000-4000 MET-minutes per week gain maximum health benefits, though even small amounts of activity above zero provide meaningful health improvements compared to being completely sedentary.
How do I find the MET value for different activities?
MET values for hundreds of activities are cataloged in the Compendium of Physical Activities, which is a widely referenced research database maintained by Arizona State University. Common MET values include walking at 3 mph (3.5 METs), cycling at moderate effort (6-8 METs), running at 6 mph (9.8 METs), swimming laps (8 METs), yoga (2.5 METs), and competitive basketball (8 METs). Light household activities range from 2-3 METs, while vigorous sports can reach 12 METs or higher. The Compendium is freely available online and is regularly updated with new activities. Keep in mind that actual energy expenditure can vary based on fitness level, environmental conditions, technique, and body composition.
How are MET-minutes related to calorie burn?
MET-minutes can be converted to calories using a straightforward formula that incorporates body weight. The formula is Calories = MET x body weight in kilograms x duration in hours. Alternatively, since 1 MET equals 1 kilocalorie per kilogram per hour, you can calculate calories as MET-minutes x body weight / 60. For example, a 70 kg person performing 6-MET exercise for 30 minutes burns approximately 6 x 70 x 0.5 = 210 calories. This relationship makes MET-minutes particularly useful for weight management because they provide a direct pathway to estimating caloric expenditure from any physical activity. Heavier individuals burn more calories at the same MET level because they are moving more mass.
What is the difference between moderate and vigorous MET activities?
Activities are classified by MET intensity thresholds established by the American College of Sports Medicine. Sedentary activities (like sitting or lying down) have MET values of 1.0-1.5. Light-intensity activities (slow walking, light housework) range from 1.6 to 2.9 METs. Moderate-intensity activities (brisk walking, recreational cycling, dancing) range from 3.0 to 5.9 METs. Vigorous-intensity activities (running, competitive sports, fast cycling) range from 6.0 to 8.9 METs. Very vigorous activities (sprinting, high-intensity interval training) exceed 9.0 METs. The WHO guidelines note that one minute of vigorous activity counts as approximately two minutes of moderate activity when calculating weekly MET-minutes, reflecting the higher energy cost.
Can MET-minutes predict health outcomes?
Yes, extensive epidemiological research has established strong dose-response relationships between weekly MET-minutes and various health outcomes. A landmark meta-analysis published in The BMJ found that individuals accumulating 600 MET-minutes per week (equivalent to 150 minutes of moderate exercise) had a 20% lower risk of all-cause mortality compared to inactive individuals. Those reaching 3000-4000 MET-minutes per week showed up to 39% reduction in mortality risk. MET-minutes have been shown to predict reductions in cardiovascular disease risk, type 2 diabetes incidence, breast and colon cancer risk, depression symptoms, and cognitive decline. These relationships hold even when activities are accumulated in short bouts of 10 minutes or less throughout the day.
