Lactate Swim Test || 6x400

[@bimpfi16]

Im so hyped every time I see a Lionel video popping up on my main page!

[@markrau7628]

Me too

[@L-dw5sx]

Same come on Lionel World Champ 2024 unleash the lion 🦁

[@haucks]

Hi Lionel, thank you for this excellent video. I believe there is a lot of very useful data to be gleaned from this session. 1. Your pace at lactate threshold (LT2) is 1:14-1:15, which is about 10 seconds per 100 slower than the fastest triathlon swimmers. I am guessing that you can bring this down to 1:10/1:11 within about 3 to 6 months once you get back to heavy swim training with Gerry. 2. Your maximum lactate production is quite low. Most fast swimmers would probably produce 6 to 12 mmol/l during an all out 400 swim. 4.5 mmol suggests that your anaerobic system is very underdeveloped and/or your current technique does not allow you to swim at speeds necessary to produce those numbers. High end swim speed is of course very important given how pro triathlon swims are often all out for the first 200 yards or so. I am sure Gerry has a plan for this as well. Good luck!

[@viivnmusic]

I think it’s normal to have an underdeveloped anaerobic system when doing long distance triathlon. Curious to know what you’d recommend to improve his swim pace. Saying that, we all know swimming has been Lionel’s weak point (with all respect) for some time. It’s a tough one to improve too.

[@Josh_lewis]

@richardmocnik6631 I can produce double digits on all three disciplines 👀 this weekend isn't looking good.

[@CoachGareth]

Even the best endurance swimmers have access to anaerobic speed and lactate typically well above 6-10 mmol when swimming flat out (

[@nathanmclain9027]

This is intersting AF. You're now a pro KZbinr my friend. Keep this up and your going to get every age grouper nerding out on your channel.

[@chrismack2027]

Might want to have a look at that leg kick 😉

[@adam_tri_hard]

Well done Lionel for finally putting some real science behind your training and racing. This will pay huge dividends to you in 2024.

[@Natalie-rl7dq]

This was absolutely fascinating and as someone who appreciates data and analysis of data sets, I was geeking out. But also incredibly interesting how much your Lactate jumped with a huge increase in effort without a lot of gain of speed. I love this because it only confirms how much swimming is so technical and important to create GOOD and STRONG Form from the very beginning before you can even talk about getting faster. Thanks for doing this!

[@TylerSinden]

I'm just starting out and swimming is by far my worst discipline. I have minimal experience running and no biking and swimming experience outside of my last two months of training. Watching these videos has definitely increased my drive to want to train harder and learn more about everything to improve my overall ability. Love these educational videos!

[@andreasderudder1671]

I noticed when you're breathing, your leading arm (on which your head should rest) is dropping way too much. It should stay in the extended position until your head is back in the water to reduce drag. Example: minute 2:36

[@cameronyoung91]

Keep up the good work mate! Stoked to see the analytical approach towards fitness gains! Side note, I signed up for my first ever 70.3 ironman thanks to you. Would be awesome, if you could do a competition in South Africa one day.

[@tennvtxr]

Dedicated triathlon coach. Been guessing for years. Guidance from one great coach is probably a good idea. Don’t reinvent the wheel, just improve the wheel. Time is ticking. I’m a big fan and wish the best for next year.

[@akg5306]

Thanks for still putting out content! Makes the off season a little more bearable as a fan of the sport not to mention these geeky insights are very interesting!

[@marcatthecorner273]

Great video. I'm starting to now believe that you'll make an excellent coach one day. Keep surrounding yourself with the best, and please keep listening.

[@yendoradon7836]

Point the foot, lock the knees, hold legs closer together 😊

[@larrylem3582]

The data looks great, very well-defined, very useful. The conclusion is spot-on, too. Practice technique, test every so often, get those curves moving to the right. I'm not sure why he talked so much about gathering data and not needing it since it is obviously needed.

[@JameAndy-ge4ck]

It looks like technique could have a big impact. It looks quite laboured and heavy on his left side, which is stopping him ‘gliding’ through the water. I’d love to see Lionel make good improvement in the swim. He’s able hit some big watts on the bike and has good run speed too. If he was able to come out near first in the swim, we’d be seeing him on that top step a lot more.

[@carlopieratelli4489]

Great video! You got me hyped for seeing the progress over your lactate in the next few months. That's kind of crazy, I never thought I would be so invested on someone else's training. It's very helpful to see the science behind this study. Keep up the good work ❤

[@MsBenFrog]

Thanks Lionel. Besides being one of the most inspirational athletes, you are also producing the most interesting videos in the field. I am so eager to see you succeed.

[@trulswagener665]

in my opinion that is not Lt2, but closer to LT1. LT2 usually is around 3,5-3,8

[@MathisW20]

Great Video :) thank you Lionel. Lots of love from Germany

[@kain12343]

Really loving this content. Seeing this is not only motivating but extremely educational. Thank you!!!

[@fabrizziofernandez6540]

I feel like the high elbow catch of Lionel is looking better !

[@joshuafoulds8107]

I'm really enjoying these testing videos and am excited to see how things progress over the next 8 weeks. Will these results be used to dictate training or just to have a benchmark for comparisons?

[@jeoffreynierding2956]

M. SANDERS, Thanks for your video. Data are very important but efficiency comes with a properly technique. Because swimming is a technique activity. Yours is not good enough, you can do much better!!! I wish you the best, god bless you! Jeoffrey NIERDING triathlon coach since 1999.

[@smkynbandt1]

Great video and explanation of what you are doing on this set and future sets. You are more than welcome to come and swim with our Masters group if you are ever in the Charlotte, NC area.

[@angelrivas4042]

Physique looks incredible!

[@ironmantooltime]

Yea really needs to cut some body fat, all those off season slurpies 😂

[@scottparrey7851]

You are an inspiration, Lionel. Are you and your swim coach looking at your underwater catch and pull? Improving this component of you stroke will improve speed and efficiency, allowing you to swim faster with less effort.

[@rylanrussell9595]

Wow, Lionel seems a lot more grounded than he has in other recent videos. Refreshing.

[@coachw5245]

Gerry’s key principles are prioritised as tautness, alignment then propulsion. It appears to me that as you work on your tautness, which will include ankle flexibility work, your tautness will naturally improve and then you will naturally move through the water at a greater velocity using the same energy. As you state, knowing such data will if nothing else increase your belief in the process. Thanks for sharing. It would be great to also get Gerry’s input on camera [I did watch you on his Tower 26 podcast]

[@Lankysprinter]

More great content, really interesting and what you’re saying in the pool at the end makes total sense- this data is interesting but not crucial for developing swimmers.

[@L-dw5sx]

1:22 per hundreads yards with 104 hr 😂 mines higher than that going for a walk Lionel’s a beast 🦁

[@hansmeiners6668]

Thanks for sharing. You got this Lionel

[@samlunger8777]

Fascinating! Should you reverse the order of the test? To rule out the possibility of cumulative lactate and stress.

[@bonn1771]

More data if needed smart. Looking forward to next test

[@marcoferraris6451]

Thanks Lionel for sharing

[@sabra31]

Great video ! Thx for sharing. Would love a link to the d max formula

[@MultiWhatever1001]

First few seconds I thought Lionel went fishing

[@benbos1925]

Nerdy question alert ! :-) Since Swiming is such a technique heavy sport, do the same principals apply like run/bik with regards to these Lt1/2 zones when we are targeting development of different energy systems. Put differently the long easy rund rides are done to develop mitochondrial efficiency and capilary density. Do we also target this in the swim ?? Or are you, in the swim just looking at the Lactate as a measurable metric to test the efficiency of your technique.

[@sefintri]

Vlacmax y good test for Glucolitic power vs Aerobic power. Book Jan Olbrectch is good for this concepts, Nice Job LS, good luck in seasion 2024

[@Robertcotterell]

Just wondering what his next epiphany will be. Might be time to move to Andorra like a lot of young pros.

[@markscott2259]

Ok! Lionel Thanks for sharing. I see one issue that is going to be resolved. Lower half of your body is sinking to much. Please keep videoing under water so we can watch the improvements!!

[@blainetaylor2272]

Love this stuff!

[@darringrey4329]

Body drag/ efficiency trying to overcome that buy swimming more?? Check the feet on the overhead ankles are locked toes pointing down drag drag

[@paulmcallister2380]

You ever try keeping that air in the lungs a little long to maintain that buoyancy through your stroke? From under water shot looks like you expel the air (deflate your buoyancy balloons/lungs) too quickly.

[@ryanclerkin9827]

His feet also turn out like giant anchors on his breath stroke

[@paulmcallister2380]

Yes I hope Lionel doesn’t think we are being Negative or be armchair coaches. I’m just trying to observe and if I can give feedback from things I’ve learned then hopefully it can help in some way. Love how he shares and is so transparent!!

[@heikkisanelma6625]

hope you stick with it, make the tests to track progress and program your training... BLA testing is not useless, this just told to everyone that you have swim biomecanichal efficiency problem at hard efforts that limits you producing propulsion in same projection with your exerted effort... ofcourse for any one you basically just need timer and distance and do the pace per distance curve or power per duration curve to basically get the same outcomes of ones physiological status and sport spesific economics and thus make the plans to hone those sport spesific demands.... but its all for nothing if the testing is sprodiatic...

[@andreaswolff2010]

Are there no 50 m pools ?

[@kiwixify3]

Really interesting video ! Thanks

[@mvschooten]

How do you use this in your training, are you going to apply the know 80/20 Aerobe/Anaerobe training. So improve your slow muscle fiber and build a bigger aerobe zone, moving LT1 towards LT2?

[@joshpain349]

When you re-test. Will you factor in the fatigue and or freshness that you currently have? I presume you will be ramping up the training and when test next will have additional load and fatigue? Will this effect your baseline re__set?

[@brentcharlton1065]

Gainzzzzz to be had! Go get ‘‘em Sir!

[@juliaflorida]

This test distance was in yard, not meter, right?

[@TheDomLouis]

I really do hope you go back to lactate training. The science is used by world professional cycling teams and some of the best runners, from middle distance to marathons and now triathlon and beyond for a very good scientific reason. Its one part of the marginal gains at the pointy end of endurance sports!!

[@edwinhmwong]

Work on technique is much better than treating swimming as a fitness focus sports

[@jonathanstpb]

Great video!

[@Mirar90]

You mentioned that you also wanted to find LT1 here Lionel. Did you actually do that? What is your resting lactate? I think you might have started to fast and already missed part of the curve to actually identify LT1, which should be at the first inflection point of the curve

[@Air1_R1]

Honestly you should simply learn & train the basics. 2:30 to 2:40 is horrible to watch. Most 14yo kids in my club swim better and faster than that. Considering they have probably les than half your muscle and heart capacity I think improving your technic is the best and probably only way to get a breaktrough. A guy in his 30's in my club swim around 10k per week max and do only technical sessions. He swims 1:10/100m endurance. He does butterfly, swims drills, one arm crawl etc... He made 4th in his first Iron Man quebec 3 years ago. Swim is definetely different than running and cycling. Simple opinion.

[@oneflyg35]

Would be curious to see lactate levels if this 6x400 was done in reverse. Meaning do the faster set first, and then slower with each repeating 400.

[@duniaz385]

or ... all 400s at aprox. same speed

[@QUALIT_LEAP]

lt2 to 2 mmol? And what happens with lt1? Where is lt1?

[@abuckeye26]

Looking more ripped than normal Lionel, looks like the healthy diets working

[@GordonA-Jr]

Dang Lionel you look shredded and ripped!!! How about a bud on your nutrition and hydration. Plus do you do any strength training as a part of your regular routine?

[@GordonA-Jr]

Oops how about a video on nutrition

[@DanEvo21]

The last 400 being max effort 125bpm is your max hr or near too it ?! Is the whoop accurate without a hr strap ?

[@samholder196]

interesting -- and, it seems, sound -- analysis on lactate on a developing swimmer. So the key is technique work?

[@eitanshushu]

lactate is fitness. weak swimmers should focus on technique, its much more efficoent in terms of speed improvement.

[@ironman140.6]

Lionel, I have a question... how long is this process to becoming a front-pack swimmer.

[@smann3553]

Is there pontential of you getting faster?

[@cyruse7027]

Hmm, honestly looks like you measured LT1, not LT2....But would have been good to see a resting value and then maybe 1 extra "easy" value just to get the baseline set correctly. Edit: just realized he was calculating Dmax, so technically that's neither LT1 or 2!

[@ironmantooltime]

If u swim and 800 and a 1500 below LT do you stay below LT?

[@blinzi69]

hows your aero testing going?

[@TheRealRoch108]

Dude....Lactate doesn't matter unless you fix your stroke. 80% drills

[@gtkona1608]

Three decades ago when I was WAY into triathlon, 29 times racing in Kona, I had the good fortune to interact with several excellent swimmers. A Top collegiate swimmer, he could cruise at 1:00 per 100y, described a week long swim camp: Hours per day, technique only. Practice does not make perfect. Perfect practice makes perfect.

[@TheRealRoch108]

@@gtkona1608 Yep...I made OT cuts as a teenager & swam at Indiana University in the 80's. (quit after a year cause I was winning $$ racing bikes) Freestyle wasn't my best stroke but I still could go 45 flat for 100 and 139 for a 200 and slip under 4;30 for 500. We swam 40-60K per week and during "hell weeks" we came close to 100k. More than 1/2 is technique and drills. technique is EVERYTHING

[@NeilGanshorn]

Should you also be finding a threshold level while wearing a wetsuit? Otherwise training may not correlate with race pacing. Then again, you can’t train how swim drafting will affect your LT…

[@stephenhandel5565]

Why don’t you just swim more open water, if you feel you’re not fast enough in an open water race?

[@AntonKomarov]

I know a guy who can help you get to another level.. take him as swim partner 👌🏼 and you’ll see the difference.

[@cdnnurse01]

If you get frustrated and want to go back out on your own, say these over in your head, "As an athlete you have to be coachable, and being coachable is a humbling thing."

[@carolyncroxall1362]

Chill people … he is working on technique …He’s taking a baseline , working on technique then going to compare

[@Bockeylife]

🤔pool

[@andrewmetcalfe9898]

OK - to keep banging on a drum: to swim in the ‘Ditlev’ pack in a PTO or 70.3 Chmapionship race you need to swim at that target pace in training - for long reps - consistently (ie. once a week). You have done this before - 1:15 minutes per 100M for 1500M (long course pool) back before covid. You are correct - at this stage in the season physiological metrics are irrelevant (ie. I would NOT care if your lactate was 10, so long as you were hitting you pace marks because - as one of the fittest people on the planet - once your body adapts to the biometrics of swimming ‘fast’ (by Triathlon standards, which is still very very slow by swimming standards), your physiology will catch up rapidly. Even at this early stage in the season, you could do a lot worse than incorporating the following session in to your weekly routine (this the the key session that turned Aussie Pro Chris Kemp into a 3rd pack - 27 minute swimmer - into a front pack - 23 minute swimming at 70.3 races a decade ago [and in only a matter of months]: Main set: 8 x 100M on 1:15 pace (start off with a 2 minute /100M repeat cycle, but decrease this with increases in fitness over time]; 200M swim down; followed by 4 x 200M on 2:30 (so holding your target 1:15M/100M pace); 200M cool down; followed by 2 x 400M on 5 minutes. Given that lactate test, you may well end to increase the interval time, or the recovery time between each of these three components that comprise the main set. But remember, this set is not about being ‘hard’ or ‘threshold’ (although it will hurt). This is about speed: sustained target race pace speed. Also do this session in a long course pool. I know there is one in your home town!

[@victorantunes3743]

where is this pool??

[@katesommerville5786]

Gated community...private access.

[@CoachGareth]

Can you please explain how you come up with the comment "this explains why lactate is of very little value to a developing swimmer". It baffles me but I'm open to your input and knowledge here..... I've been lactate testing endurance athletes of ALL abilities for many years and (just as in cycling and running), high lactate levels at low performance outputs are indicative of under-developed aerobic systems. Low lactate at high outputs (like in your test) show under-development of the Anaerobic energy systems. So for age-groupers lactate testing is VITAL otherwise they just slog away in masters workouts never developing their base endurance (from training at constantly high lactate levels) and therefore never get faster. Through lactate testing "developing swimmers" learn to train more accurately. As @haucks rightly said, one of your limiters is a poorly developed anaerobic system that is limiting how well your "hybrid" metabolism is working in the water. I hope you train that correctly in the coming months. Best of luck.

[@rubynette]

LT1 IS AROUND 2 + OR - 0.5 AND LT2 IS AROUND 4 + OR - 0.5. I AM SUPRISE TO SEE LT2 AT 2 ON YOUR CHART ???

[@marcgraveline1771]

There are many interpretations of what LT1 and LT2 mean. But a common definition is LT1 is a measurable increasing over resting levels and LT2 is when lactate production will outpace lactate clearance and lactate will accumulate. For many people LT2 is around 4 mmol/l but not everyone and certainly not elite athletes. Different methods of interpretation are valid, but best is to use one method and stick to it for comparisons over time.

[@bretgreenfield9501]

Just going to say this,,,the elevation view says it all, the view where I am looking directly down on your stoke, kinda looks like a turtle, that's hurt, no glide at all, it's like this, you think wind tunnel is going to make you faster on the bike,,,well water is like way more finicky then wind, so you really need to find someone like me, because what you are practicing, is all wrong, the more you swim like this, the worst you will be, it's a golfer who's sing is off, no matter how much you practice, it must be correct, or it's a waste off time,

[@thepatternforms859]

No clue how anyone uses those form goggles. Visibility is garbage! Like looking through two coke bottles. Worst goggles I’ve ever used

[@LegendJeff]

Agreed

[@beachedbeluga]

you need trechnique work not lactate testing

[@Clauds43]

Comparing pro endurance athlete to us mere mortals can be seen with his average HR

[@joshpain349]

Elite swimming for most age groupers… think about this swim data when you think of Lionel as someone who sucks at swimming. Yes, it’s relative to pro’s… But most people who watch probably think he is shit.

[@sjdj3000]

Lots of drag and swimming with strength not technique.

[@sambrown1779]

More time wasted. Use the stopwatch. Forget the lactate

[@pavanatanaya]
