How Many Calories Does Flag Football Burn?

Flag Football calories by weight & duration

The ~562 calories per hour figure is an estimate for a 155 lb person based on a MET of 8, and your real burn will shift depending on your body weight, fitness level, and how intensely the game unfolds. You can log your flag football sessions in the Mariposas app to track your personal calorie data over time.

Calculated as MET (8) × body weight (kg) × hours. How this works.

What to expect in a flag football class

A first session usually opens with some light dynamic warm-up work, a quick walkthrough of the rules (flag-pulling mechanics, line of scrimmage basics, scoring), and some route-running or defensive footwork drills before the group moves into actual scrimmage play. The pace can feel surprisingly relentless because there's no huddle-to-huddle recovery like in traditional football. You'll be jogging back to the line of scrimmage, running a route, chasing a receiver, and then doing it again within seconds. Plan on being winded.

Tips for your first flag football class

• Learn the flag-pulling motion before your first game. Grabbing at someone's hips rather than going for the flag directly wastes time and often misses. Practice a smooth, low swipe at the flag during drills so it becomes automatic.
• Play a simpler defensive position (like a middle zone defender) your first few sessions rather than trying to shadow a single receiver man-to-man. Zone coverage lets you read the play developing in front of you, which is much easier to process while you're still learning the rules.
• Wear non-slip athletic shoes with good lateral support. Flag football involves a lot of sharp cuts and sudden stops on grass or turf, and a shoe designed for running in a straight line will slide out from under you on those cuts.
• Hydrate before you arrive, not just during play. The stop-and-start nature of the game can mask how much you're actually sweating because you get brief rests between plays, but the cumulative fluid loss adds up quickly across an hour.

What affects how many calories flag football burns

The MET value of 8 puts flag football firmly in vigorous-intensity territory, but your actual output depends heavily on your position, how competitive the group is, and how much ground you personally cover in each play. A receiver running full-speed routes on every down will burn considerably more than someone playing a stationary quarterback role. The 562 cal/hr estimate is calculated for a 155 lb person at that MET level, so heavier athletes will burn more and lighter athletes less, and a tighter, more competitive game will push the actual figure higher.

Three things move your number most: body weight (a heavier body burns more for the same activity, that's why the table runs from 125 to 225 lb), duration (calories scale with time), and intensity. A flag football you push hard burns more than an easy one, because effort is what the MET value of 8 represents, an average for this activity. Your fitness level and how much you rest between efforts shift it too, so treat these as a solid estimate rather than an exact count.

How we calculate flag football calories

Every number here uses the standard energy-expenditure formula: calories ≈ MET × body weight (kg) × time (hours). The MET value of 8 for flag football comes from the published Compendium of Physical Activities, the same reference researchers and fitness trackers use. We convert your weight to kilograms and multiply through, no fudge factors. See our methodology for the full formula and sources.
