Myths of MMA Conditioning

Rich Franklin MMA Conditioning

We’ve seen it before, and it’s an awful thing to watch. It’s the middle of a fight, everything’s going well, and before you know it, a fighter “gasses out.” Sometimes he’s saved by the bell, and sometimes he’s even able to defend himself enough to continue and regain his strength. More often than not, however, he’s left defenseless and his opponent takes advantage and ends the fight.

Countless fighters have lost fights this way – even some of the biggest matches of their careers. And it’s not because their opponents had more skill or better strategy, but because they gassed. From amateurs to top professionals, regardless of the level of competition, gassing out is the great equalizer in combat sports.

Given the obvious importance of making it through an entire fight without gassing – not to mention what’s often at stake for a fighter’s career – we need to know why so many fighters gas out in the first place. This would be understandable, to a degree, if we’re talking solely about amateur athletes, but when world titles change hands because one of the fighters gassed, it’s clear this phenomenon has little relation to skill level or experience. In fact, it’s rare to see an entire card, even at the UFC level, without someone gassing out.

We see these debates online all the time. People want to know why fighters did or didn’t do certain things when they lose, and when it’s because they gas, the near-universal consensus is that it happened because they “weren’t in shape.” After all, when you’re out of shape, you’re bound to gas out sooner or later – and when you’re in shape, it means you can always last bell-to-bell, right?

The casual fan believes the answer to this last question is a resounding, “yes,” but the real answer is far more complex than you’ve been led to believe. If you don’t know anything about the sport and you watch a UFC card, it probably doesn’t look much different from a bar brawl. If you’ve tried MMA for even a day, however, you understand and appreciate how incredibly technical and precise the sport is. In this same spirit, gassing out is far more complex than most people realize.

The more you understand about how energy production in combat sports really works, the more obvious it becomes that thinking fighters gas simply because they’re out of shape is akin to believing that getting in a lot of street fights qualifies you for the UFC. If you don’t understand the tremendous skill involved in fighting, this may seem logical, but anyone who has ever set foot in a gym and trained knows it’s just not that simple.


MMA Conditioning Myth Busting

To begin to form an understanding of the bigger picture with regard to conditioning, gassing out and being in shape for combat sports, we need to start with a clean slate and put an end to many of the common myths surrounding the topic. Despite its importance and the frequency with which gassing out occurs, there are more misconceptions about this aspect of the sport than almost any other.

“He built up too much lactic acid”

Despite the fact that scientists have known that this is not the case for many years, this myth is all-too-frequently cited as the underlying mechanism of what happens when a fighter gasses out – even by otherwise knowledgeable people. The truth, however, is that lactic acid is never the reason fighters gas out. This is because it doesn’t even exist in the human body (Robergs RA, 2004). There is never any lactic acid in your muscles, either during fights or otherwise.

Instead, a substance known as lactate is produced when your body breaks down carbohydrates and turns them into an energy source your muscles can use through a process called anaerobic (without oxygen) glycolysis. Rather than causing fatigue in your muscles, the chemical steps that result in lactic formation actually help prevent fatigue, and are an absolutely vital process in energy production. In other words, lactate is your friend, not your foe.

“He ran out of gas”

This is a catch-all term that essentially means a fighter is running low on energy, and it’s another one that seems to make sense on the surface, yet fails to hold up under the microscope of exercise physiology.

The truth is that the chemical fuel on which your muscles and your entire body run, Adenosine Triphosphate (ATP), never drops below 60% of resting levels in working muscles, even during the most intense periods of exercise and exertion (Westerblad H, 2010). Fights also don’t last long enough for your muscles to run out of glycogen, the stored sugar used to make ATP.

You don’t fatigue because your muscles run out of energy. It doesn’t happen, because your body is smarter than you. If your car runs out of gas, you just end up getting stuck somewhere. By contrast, if your muscles actually did ever run completely out of ATP, there would be serious cellular damage, and you’d be in major trouble.

To prevent this from happening, the body has a number of failsafe mechanisms in place to make sure your muscles never run as low on ATP as people run their cars on gas. The entire metabolic system is designed to make sure there is always gas left in your tank. It may look like a fighter has no energy left whatsoever when he’s gassing out, but in actuality, his tank is more than half full.

 “He Was Just Out Of Shape”

We’ve all heard fighters say they feel like they’re in the best shape of their lives going into fights – or talking about how they’re able to “go forever” in training – only to end up gassing out in the second round. What happens here? Were these guys not in the kind of shape they thought they were? Are all fighters who gas out in bad shape?

There are two sides to the equation here: energy production and energy expenditure. If you don’t look at both sides, you’re failing to see the whole picture, and this makes it easy to formulate incorrect assumptions. Energy management is really what determines whether a fighter can go bell-to-bell – or ends up gassed out and face-down on the canvas.

Picture two fighters who are both in the same shape. They’re about to fight each other. Fighter A is determined to finish the fight quickly and loves to knock people out, so he swings for the fences with every punch and is constantly pressing forward. Fighter B, by contrast, is highly defensive. He’s patient and carefully picks his shots – always waiting for a mistake to capitalize on before exploding and expending a lot of energy.

It’s not hard to see which fighter is more likely to end up gassing out. Fighter A is constantly expending more energy at a much faster rate than Fighter B, so consequently, he’ll fatigue much more quickly. If he can’t finish the fight early, he’ll likely be significantly slower and gassed out by the end.

This difference in energy management – how and when each fighter chooses to use the energy they’re capable of producing – plays the biggest role in how quickly they fatigue. A fighter can be in great shape, but if he manages his energy poorly, he’ll still end up gassed before a fighter who’s smarter about his pacing and energy expenditure.  This is why fighters gas out at all levels of the sport. The top professionals are typically in much better shape than the guys at the bottom, and they’re still producing a great deal more energy. No matter what kind of shape they’re in, however, they can still gas if they don’t use their energy wisely.


Why MMA Fighters Really Gas Out

To understand exactly why poor energy management can lead to gassing out, you have to examine the basics of energy production. We’ve established that muscles don’t fatigue because of lactic acid build-up, and they’re not running out of energy, so what’s really happening?

Although science can’t fully explain the mechanisms yet, it’s well documented that the greater force and power a muscle produces, the faster it fatigues (Enoka RM, 1992). This is why you can’t run a mile at the same pace you can sprint a hundred meters. The more energy your body produces anaerobically (without oxygen), the more power it can generate – but the faster it will fatigue. Higher power activities require ATP to be supplied at a greater rate, so more of it has to come from anaerobic energy production.

Every fighter differs in how much energy they can produce aerobically and how much they can produce anaerobically – and there’s an inverse relationship between the two (Wadley G, 1998). The more energy a fighter can produce aerobically, the better his endurance will be, but the less force and power he’ll be capable of generating. By contrast, fighters capable of the highest power levels also experience the greatest rate of fatigue.  This inherent tradeoff between a high work rate (power) and the ability to maintain it, combined with management of energy expenditure, provides the big picture of why fighters really gas out.

Fighters capable of producing a great deal of energy aerobically and managing it effectively will last from bell-to-bell every time. Fighters who can’t produce as much aerobically and have to rely on the anaerobic side – or fighters who don’t know how to pace themselves – are much more likely to gas out every time. The truth here is that energy production and management is as complex and variable as the fight-specific skills that are being fueled.  To the educated eye, gassing out is not a simple issue at all, but yet another piece of a complex puzzle that ultimately determines whose hand is raised and who is left lying on the canvas.

  1. Great article as always Joel. I was just discussing the same issue in soccer (or any other sport). Game performance vs. conditioning level. It is not just that simple… linearly simple – improve conditioning (VO2max, vVO2max, RSA) and the performance will improve. Yeah right!

    You might find this reply by Martin Buchheit interesting

    http://www.springerlink.com/content/vg2152440271v601/

    Basically, he showed that game performance is a lot more complex than improving YoYo test. For example, central defender cover less ground with high intensity running that attackers in the game, yet the have better YoYo score (read: better conditioning and aerobic engine). Will they improve game performance (distance covered at high intensities, although the new research showed that top team actually cover LESS than team that finish at the bottom of the league; although I wonder about ‘fatigue’ percentage or the distribution of the high-intensity running, especially at the last 15-20min, not just total or average) if they improve YoYo score? Hmm…. the answer is complex… it just not that simple. There are tactics, game plan, opponent… The point is conditioning improves potential (energy production). How is one to utilize it depends on a lot of other factors. Even very conditioned team show decrease in performance (again tactics or fatigue?) during the last 15-20min. Even if we test guys with MAS (maximal aerobic speed) of 15km/h and 18km/h in 6min run, if the 18km/h guy start all out he will die at 2min mark and show worst performance due pacing….

    Keep up the great work Joel!

    1. Absolutely. I think it’s an error saying more high intensity running = better performance. Really, it probably suggests the opposite (as you pointed out). Good teams will control possession and set the tempo of the game to their liking. As an example, a team like Barca won’t work as hard as their opponent and their expenditure seems to be a lot more alactic-aerobic. Nice easy passing, until a final burst to get clear/attempt on goal. Another reason why top teams would work less, is simply because they don’t have to. You see it all the time. A top team generates a goal or two within the first 45-60mins, and then can sit back and slow the game down. In contrast the opposition have to ‘chase the game’.

      Anyway, nice article, Joel.

  2. I do agree that someone who has completely gassed out is dead. There is always energy around to support basic functions. But until the muscle’s PH rises, it will be difficult for the affected muscles to operate. My understanding is that while lactic acid isn’t the culprit directly, its breakdown into lactate causes a change of PH in the muscles which is believed to cause fatigue. The breakdown releases H+ ions which create a locally acidic state, impacting performance.

    As well, fatigue can be “subconsious” if you subscribe to the central govenor theory, which partly explains why towards the end of a round fighters can muster the energy that they were unable to mid-round. The finish line is in sight and the brain or subconscious mind feels safe releasing the remainder of energy it can at once. Novice runners tend to think that they won’t have enough left for the finish so often hold back more than neccessary. It seems that the reverse assumption is true in novice fighters.

    Aerobic training can certainly help with all areas except perhaps the subconsious, although even this can be gradually
    retrained.

    1. Please read the reference I cited for the discussion on lactic acid. Most research now is showing the change in pH has much less impact on contractility than previously thought and Robergs and others argue that the H+ is not a result of anaerobic glycolysis but rather further up the chain. Fatigue is a highly complex issue with many different components that are not all well understood.

      1. I can accept that it’s not lacate production or even ammonia that causes the acidosis, but ATP/glycolytic acidosis, because all explanations are equally hard to comprehend! The main point to me is that it is acidosis that appears to cause fatigue. Although I have also read that calcium leakage is another possible factor. As you say, the whole problem is extremely complex and also impossible to measure directly, so it is the solution that matters most to me.

        I’m also curious about aerobic training in that it has few direct adaptations for the arms/shoulders (unless a lot of swimming is involved). The fibers that are affected are in the legs/hips primarily. How does this help the arms? I’d also be curious about your understanding about Hershel Walker, who seemely has great aerboic and anerobic capacity. Although there is a trade-off within a session or day developing both anaerobically and aerobically conccurently, can both capacities be developed to extreme measures over a long time?

      2. The references were very informative but I’m still not sure how training programs should change based on that information. It seems that although lactic acid is not playing the role previously thought threshhold training is still efectivve?? Or is the real conclusion to focus on improving aerobic capacity and maximal effort/power during the”off season” and only switching to training the glycogen lactate system for events or competitions?
