Patrick Mahomes HR and Calories Burned vs Bills - Does this sound right?

No clue about calories, but based on a tiny bit of research I'd say the heart rate is total BS.

"Experts consider a flight or fight heart rate of 115 to 140 beats per minute optimal for sustaining rapid, coherent thinking and quick reactions. But above 140 bpm, the sympathetic nervous system begins shutting down certain “unnecessary” bodily functions in order to focus on survival."

And more importantly:

"At 145 bpm, you lose most of your ability to do complex motor skills or movements – remember how people in movies fumble to get a door open during critical moments?"

"Above 170 bpm, your thinking is reduced to the primitive fight or flight response. Running (or charging) is at its peak performance. The vast majority of people also tend to lose control of their bladder and bowels at this stage because even those functions consume resources that the body prefers to save for fighting or running."

No way on the 2,367 calories. No way at all.

If his heart rate was 160 for more than a few minutes during the game, there is something wrong with him.

This is assuming the heart rate is mostly due to adrenaline, not exertion, which imo is a fair assumption for a QB

I am surprised Patrick Mahomes is able to run around as he does on a football field. He is not fast and Patrick Mahomes is fat as was Dan Fouts. My guess, defenses do not want to get beat deep by T. Hill so there are running lanes for Patrick Mahomes. A 4.8 guy running around as if he's a 4.2 guy like Mike Vick in his prime. His father was a fit and lean 6'1" 175 lbs. pitcher for Minnesota Twins.

1. Heart rate monitors can be very inaccurate on the high end.

2. Max HR of 191 on a full sprint running play sounds right.

3. Some of the interesting HR spikes were when he wasn't even playing! During Chiefs tying FG, during Bills go ahead drive, during a teammate's TD, etc.

4. His HR really never dipped on the low end except during halftime. It was fricking cold at that game, and you want to keep moving on the sideline to stay warm. It doesn't look like his HR really ever dipped below 120 once he was out of the locker room, and that actually seems right. 120 is about a nervous walk.

5. High end heart rate of 191 and low end heart rate of 120 means the overall average of 144 seems about right.

6. An average HR of 144 over the course of 4 hours would equal about 2,300 or so calories burned.

7. Patrick Mahomes probably isn't as aerobically fit as most of us, and he weighs 230 lb (still a much better athlete).

8. A lot of people on here have clearly never played team sports. I wore a HR monitor during a rec basketball game once, and my average HR was 158 for the game, which was two 20-min running clock halves. This is about the same as my HR during a similar length easy run in 75-80 degree weather. Bursts of sprinting, jumping, shooting, throwing, etc. can really spike your HR.

I actually think this is totally plausible.

First, remember that chess players can burn as many as 6,000 calories per day. A QB in the NFL has to do a lot of thinking, analysis, and decisionmaking. Obviously the NFL doesn't require the same amount of brainpower, but I can see 2,300 calories over a 4 hour game.

The heart rate is almost certainly related to stress and adrenaline because of how big the moment is. I referee soccer at a somewhat high level (I've refereed matches with 5,000-15,000 spectators) and my HR rarely drops below 135-140 even if I'm standing still in "big" games. 160 seems high for an average, but it's not out of the realm of possibility.

I don't buy that amount of calories as those guys do A LOT of sitting and standing around. Halftime, they're in the locker room. Been to an NFL game? While you see commercials on TV, those guys are not doing anything physical and just resting, plus there are all the timeouts on the field as well. Time of possession is , maybe, 30 minutes. More like 800 calories.

Would love to see me data on this chess comment. That blows my mind if true!

Guessing there's no HR strap (so just using optical) - ime even with pricey models, it can get fairly inaccurate at times erring on a much higher HR.

It was on Joe Rogen's podcast, so it has to be true

Does this count pre-game warm up? Some players get there at least a couple of hours before the game to warm up.

That's a good question. I haven't found exactly when the observation period began. If we extend it 2 hours before the game kickoff then the calories become more understandable but the HR becomes less.

Agree.

You would have to run over 20 miles to burn that many calories.

No way he could burn that many calories in a sixty minute game, with much of that time spent doing little physical work.

Maybe 1,000.

(not my post, from a chess board on reddit after the recent world championship):

Sapolsky has never published any research that can back up his "6000-7000" calories a day figure, and infers this based solely on looking at chess player's heart rates and bloods pressures during the game. I hope you don't have to be an exercise physiologist to understand how heart rate variability does not directly correlate with energy expenditure. You are not burning as many calories while having a panic attack as you are while running a marathon.

Actual exercise scientists have used indirect calorimetry - the research standard in exercise physiology for energy expenditure - to actually measure how many calories chess players burn while playing chess.

Troubat et. al (

)

in 2008 found that chess players burned an average of 1.53kcal per minute at rest, and at most 1.67kcal per minute while playing chess - a modest 10% increase on average from doing nothing. 10% is a long way off the 300% that Sapolsky claims. Even if we take calorie expenditure at the top-end of the confidence interval, this would amount to only 960kcals spent over an 8 hour chess game: only a couple hundred calories higher than if you were just sitting watching TV.

Rodoplu et al. presented their own study at the 9th international scientific conference of kinesiology, where they found chess players burned 138kcals on average in a 30 minute chess game, compared to 260 kcals while those same players went for a run for 30 minutes.

There are lots of studies on HRV in chess, but sadly few in energy expenditure (as indirect calorimetry is resource expensive)

People will say that these players in these studies are not top grandmasters, and not playing serious classical tournaments. While this is true, I think you would struggle to come up with an extra 4000 calories by saying "but a top tournament is more stressful." You should not pay this 6000 calorie claim any more heed until someone publishes some evidence in support of it - because so far, all evidence suggests the calorie expenditure during chess play is only a mild increase over rest.

Of course it is true. What you aren't taking into account is that Patrick Mahomes carried 45 other players plus 16 coaches on his back for that entire game. Imagine how much weight that is.

Patrick Mahomes only needed 10 seconds to drive 55 yards down the field for a field goal when the Dallas Cowboys couldn't even spike the ball in 14 seconds.

...Patrick Mahomes is fat ...

Ha ha, only by the standard of 5-7, 138-pound letsrunners.

There’s a reason HIIT burns more calories than a long run. This man is running at varying paces for a couple hrs with lbs on his entire body and trying to stay warm on the sideline and the distance runner with baby shorts is mad they only burn 600 calories hobby jogging for an hr lol.

WTF is this nonsense? Firstly, the spectrum of HR varies wildly. Triathlete Lionel Sanders has a threshold around 140, plenty of people have a threshold as high as 180+. I know for certain that I don't lose motor function at threshold pace, and you can prove it by looking at how quickly triathletes blast through T2 in an sprint race. Losing control of your bladder and bowels above 170? Must have forgot to inform all the steeplechase and 5k guys.

I assume he and most others use some sort of preworkout stimulant, legal or not, and not just before the start of the game. That plus adrenaline and activity...I could see 160 bpm.
