Why the Anaerobic Alactic Energy System is Important in BJJ

The anaerobic alactic energy system is one of the more obscure topics when it comes to improving cardio for Brazilian Jiu-Jitsu. It’s very often not talked about and very few studies actually research the dominance of this system in BJJ. That’s why in this article, we will go in depth into this system – exploring many questions around this topic and helping you achieve superhuman cardio.

What is the Anaerobic Alactic Energy System?

The anaerobic energy system consists of two parts, lactic and alactic. They both are very dominant in short, high intensity exercises & activities – however they are slightly different. For those interested in the lactic system, check out our article detailing its function in BJJ and how it can be improved!

The anaerobic alactic energy system primarily functions during short bursts of high intensity situations where maximum muscle output is required. These situations last between 5 – 12 seconds. This system requires only a few chemical reactions to take place & is the least complex out of the 3 energy systems (aerobic, lactic & alactic).

The Biology of the System

Within the muscle tissue exists creatine phosphate (PCr), where it is stored to be used for energy synthesis and allows the muscle cells to receive ATP at a fast rate. Creatine that you ingest via food & supplements turns into PCr and is phosphorylated. This essentially means it gains a phosphoryl group.

In order to create ATP, the PCr which is stored in the muscle tissues breaks down into creatine and phosphate. The phosphate reacts with a molecule called ADP (which is produced from the energy producing reaction of ATP) and produces ATP. This process is catalyzed by an enzyme called creatine kinase? Energy production via the alactic system doesn’t produce lactic acid like the lactic system, however it also produces very small amounts of ATP. Per molecule of PCr, only 1 molecule of ATP is produced which is minuscule compared to the aerobic system. Now although it produces very minimal amounts of ATP, it’s produced at a very quick rate – quickest out of all the energy systems.

So how does the body replenish ATP quickly? During exercise, the levels of ATP will drop and therefore ADP will increase as one would expect. This increase in ADP signals the cells of a shortage of ATP & stimulates the enzyme which we talked about previously, creatine kinase. Stimulating the enzyme ensures that the cycle in the previous paragraph occurs at a higher rate!

Why Does It Only Last for a Short While?

Our muscles can only store so much PCr, when PCr stores become depleted to low levels, fatigue sets in. During high intensity exercise, PCr stores drop below the threshold for fatigue in approximately 5-10 seconds depending on the levels of PCr within one’s muscles. While our muscles recover from the short burst of activity, the creatine produced PCr is rephosphorized back into PCr after around 1 – 2 minutes.

Training the Anaerobic Alactic System

By training this system, we increase the body’s reserve of ATP and PCr & increase its efficiency in replenishing them – allowing for greater anaerobic capacity and power. This will allow for greater power for longer durations when for example shooting for takedowns and performing submission attempts.

So how do we actually train this system? Well it’s surprisingly similar to how we train the aerobic & lactic systems. High intensity interval training seems to be the key to unlocking greater anaerobic cardio according to recent literature. A study from 2022 had split 28 men into 2 categories. One was to perform short sprint intervals ranging from 6 – 10 seconds per set. The other was to perform long sprint intervals ranging from 30 – 60 seconds. Results showed that the short sprint intervals increased alactic capacity more than the long spring intervals.

In order to maximise alactic capacity training, 6-12 seconds of work with complete rest repeated 6 – 10 times seems to be the way. 6 – 12 seconds seems like a short time, however it is simply because we are aiming for 100% power & are trying to simulate situations like these on the mats. The exercise selection is the same as the other systems, these include sprints, air bike, battle ropes, shuttle runs etc. Anything that allows you to exert 100% effort & muscle output will work just fine.

Conclusion

The alactic system is an integral part of BJJ and is unique compared to the other systems as it recreates times of maximal outputs such as submission attempts. Performing 6-10 sets of 6-12 seconds of work with complete rest seems to be the most optimal way to train this system to its full effect. Exercise selections for these HIIT sessions are rich in variety & include sprints, jump squats, air bike etc.


  • BJJ Mobility for Older Grapplers: Top Exercises and Scientific Tips

    bjj mobility for older grapplers

    As we age, our joints capsules stiffen, muscle tissue becomes more tight, and recovery slows—all of which directly impact performance on the mats. That’s why exercises that improve BJJ mobility for older grapplers is vital for your longevity. In this article, we’ll explore why mobility is the cornerstone of injury prevention and fluid movement for aging athletes, and how to train it efficiently using science-backed methods.

    How Does BJJ Affect Older Grapplers?

    The sport of BJJ can be strenuous on the human body. It places high demands on usable joint mobility1 & decreases recovery ability2 in older grapplers which can collide with age related physical changes, making mobility both harder to maintain and more essential to preserve. Although BJJ can negatively affect the body, it has many significant benefits such as:

    Cognitive Benefits

    • Studies3 have found that the nature of BJJ enhances emotional refinement, intellectual engagement & promotes the overall development of individuals such as increased concentration, strategic thinking, etc.

    Muscle Preservation & Strength Maintenance

    • Jiu Jitsu has often been known to be the “lighter man’s sport” due its obsession with perfect technique with minimal strength involvement. While this may not be the best way to approach BJJ, studies4 have found that resistance from training partners can simulate strength training to a certain degree, as well as improving balance & possibly reversing sarcopenia. You’ve likely gotten stronger from rolling on the mats & not even realised it!

    The Importance of Improving BJJ Mobility For Older Grapplers

    For older grapplers, mobility training can be the secret to having increased longevity on the mats by preserving flexible & dynamic movement with reduced injury risk. There are many areas that are commonly affected within older grapplers that can seriously reduce performance & can force you off the mats for a long period of time if not treated right.

    Here’s a list of the most commonly affect areas – and why they matter for BJJ performance:

    Hip Rotation & Flexion Loss

    BJJ demands high levels of hip mobility—especially in positions like closed guard, butterfly, and De La Riva. But with age and repetition, the hip complex becomes vulnerable.

    Common age-related issues:

    • Increased collagen cross-linking: Collagen molecules form stronger bonds with each other, leading to stiffer soft tissues
    • Capsular tightening: Deep rotators and adductors shorten, restricting deep flexion and external rotation.
    • Cartilage thinning & reduced synovial fluid5: This leads to joint dryness, increased friction, and stiffness.

    Why this matters in BJJ:

    • Guard retention becomes harder
    • Inversions or hip-switching transitions become painful or awkward
    • Risk of groin or hip flexor injuries increases

    Thoracic Spine Stiffness

    The thoracic spine (mid-back) is essential for fluid movement, posture, and effective bridging. Unfortunately, it naturally stiffens with age due to:

    • Disc degeneration: Loss of hydration reduces spinal mobility.
    • Chronic kyphosis: Decades of forward posture from daily life and BJJ create rigidity.

    In BJJ, these issues are made worse by:

    • Constant flexed positions (guard, turtle, passing)
    • High loads during bridging, rolling, and shrimping

    Impacts include:

    • Poor guard passing posture
    • Weak bridges and hip escapes
    • Reduced rotational control during sweeps or transitions

    Shoulder Range of Motion Loss

    The shoulder is structurally unstable and heavily reliant on soft tissues for control. This makes it highly vulnerable—especially for older grapplers.

    Why it’s a problem:

    • BJJ positions load the shoulder in extreme ranges—frames, underhooks, posts, submissions like kimuras and Americanas.
    • With age: Rotator cuff tendons weaken, inflammation rises, and capsular tissue becomes less elastic.
    • Risk of frozen shoulder (adhesive capsulitis) increases dramatically after 40.

    Real-world effects:

    • Weaker or limited frames
    • Ineffective underhooks
    • Reduced ability to defend or recover from submissions

    Knee Flexion & Stability Loss

    Knees in BJJ take a constant beating—whether you’re in single-leg X, seated guard, or defending takedowns.

    What happens with age:

    Functional consequences:

    • Avoidance of deep guard or kneeling positions
    • Decreased comfort during takedown defense or transitions
    • Stiffness or “locking” when transitioning through half guard or knee shield

    What Happens If You Don’t Train Mobility

    Without proactive mobility work, natural age-related degeneration accelerates.

    These include:

    • Capsular contracture: Joints physically lose space and movement capacity.
    • Compensatory patterns: Poor hip mobility? Your lumbar spine or knees take the load—leading to strain.
    • Increased injury risk: Stiff joints and tight tissues6 are more likely to tear or inflame during transitions, scrambles, or submissions.

    If you want to be within the top 1% of older grapplers that can actually withstand the demanding nature of the sport & exceed new heights, implement the following exercises that will skyrocket your jiu-jitsu mobility!

    The Best Exercises to Boost BJJ Mobility For Older Grapplers

    Controlled Articular Rotations (CARS)

    CARS are a very simple movement that you’ve probably done without realising how useful they can be. They help maintain active range of motion and strengthen joint capsules. They are a very simple movement:

    • Start with one joint (e.g. hip) and isolate it.
    • Move the joint slowly through its full range in a controlled circle.
    • Keep tension in surrounding muscles to avoid compensation.
    • Perform numerous reps in each direction, per joint.

    90/90 Transitions

    A fantastic hip exercise, 90/90’s help strengthen and mobilise the deep hip rotators whilst also opening up your hips – great for flexability.

    How to do them:

    • Sit with your front leg bent 90° in front, back leg bent 90° behind.
    • Keep your chest tall and feet flat on the floor.
    • Slowly rotate knees toward the other side into a mirrored 90/90 position.
    • Try to avoid using hands for assistance.

    Tip: If your mobility is limited, start slow and try to lower your knees as much as possible without causing discomfort.

    Deep Squat Hold

    These target the hip flexors, groin & ankle dorsiflexion, allowing for opened hips & greater ankle mobility.

    How to do them:

    • Stand with feet shoulder width, toes slightly out.
    • Sink into a deep squat, keeping heels down.
    • Use a door frame, TRX rings or really anything sturdy if needed for support.
    • Hold for 30–60 seconds while breathing deeply.
    • Ensure your spine alignment is straight to prevent rounding.

    Tip: Don’t worry about having a really deep squat, lower your body as much as you can without discomfort and slowly work yourself up.

    Thread the Needle

    A great exercise for mobilising the spine, these are necessary for improving thoracic rotation for bridging, shrimping, and maintaining posture.

    How to do them:

    • Start on all fours (hands under shoulders, knees under hips).
    • Thread your arm under the opposite shoulder with your palms up, rotating gently.
    • Drop your shoulder (same side as the arm being threaded) to ensure maximal rotation.
    • Return to neutral and twist open toward the ceiling.
    • Hold for 2–3 seconds at each end range.

    Tip: Don’t let your hips shift, keep them square to the ground for a deep stretch.

    Wall Angels / Floor Slides

    Wall Angels/Floor Slides are great at targeting thoracic extension and scapular movement, Opening the chest and strengthening postural muscles.

    How to do them:

    • Stand (or lie) with back flat against wall/floor, arms at 90°.
    • Press low back, head, and elbows into the surface.
    • Contract the abdomen muscles and retract the scapula to ensure the lumbar spine keeps contact with the floor/wall.
    • Slowly raise arms overhead while keeping contact.
    • Lower back down with control.

    Shoulder CARs

    We touched on this earlier, but here’s an example of Controlled Articular Rotations for the shoulder joints.

    How to do them:

    • Stand tall or kneel; keep the rest of your body still.
    • Slowly raise one arm forward and overhead.
    • As you pass the ear, rotate the thumb down and continue the circle.
    • Reverse direction to complete a full rep.

    Tip: Keep your rib cage down to avoid arching your back.

    Sleeper Stretch

    Shoulder submissions such as the kimura can place heavy stress on the shoulder joints if you aren’t careful, the sleeper stretch targets internal rotation – alleviating stress & increasing mobility in the shoulder joint.

    How to do them:

    • Lie on your side, bottom arm at 90° across your body.
    • Use the top hand to gently press the forearm down toward the floor by gripping your wrist.
    • Hold stretch for 15–30 seconds.
    • Then remove the top hand and actively lift the bottom arm from that position.
    • Repeat on the other side

    Tip: Keep your shoulders vertical and always lay on your side, not your back.

    Step-Back Lunges (Supported)

    Lunges help strengthen and dynamically stretch knee stabilizers – allowing for greater stability, knee control & hip control.

    How to do them:

    • Stand tall with a wall or railing nearby.
    • Step one leg backward into a gentle lunge, keeping your front knee stable.
    • Lower with control, then push through front foot to return.
    • Keep reps slow and intentional.
    • Use hands for balance if needed.

    Tip: Do not round your back on the descent, always maintain a straight spinal alignment & slightly tense your core.

    Breathwork

    It’s important to maintain consistent breathwork whilst engaging in mobility exercises. They not only help reduce stress & clear your mind, they also help by relaxing your tissues & reducing muscle guarding. Here’s an example for you to follow on:

    • Get into one of the previous movements.
    • Breathe in through the nose for 4–5 seconds whilst at the peak of the movement or before it.
    • Exhale slowly through the mouth for 6–8 seconds on the descent/return.

    It’s important to have good breathing techniques when performing mobility exercises, but also in brazilian jiu-jitsu.

    Conclusion

    As the body ages, the demands of Brazilian Jiu-Jitsu don’t change, but our ability to meet them does. For older grapplers, mobility isn’t just a performance enhancer, it’s a necessity for longevity. Age related changes in the hips, spine, shoulders, knees and other areas can limit your ability to move fluidly, defend positions, and avoid injury. But with our exercises, you can reclaim lost range, reduce pain, and keep training well into your 40s, 50s, and beyond.
