I’ve been doing saddle numbness BFR training for years with excellent results! 😉

[@TSonemusic]

Why the fuck don’t you buy a good saddle?

[@avoycendeether8869]

@LittleJulio I also do BFR training by convincing myself a size M speedsuit fits just perfectly

[@8rk]

@@TSonemusic 99% of saddle problems are caused by a bad bike fit. Not saddle design. 99% of internet arguments start because people don't get sarcasm.

Other risk: It appears that BFR training has the capacity to cause significant muscle damage, and in severe conditions, rhabdomyolysis (Wernbohm et al 2020).

[@fortinbras47]

For people that don't know, rhabdomyolysis is EXTREMELY dangerous. www.cdc.gov/niosh/topics/rhabdo/default.html

[@stevenborden]

When compared to traditional resistance training, the risk for rhabdomyolysis is no different (in fact, data actually skews slightly more towards traditional resistance training as higher risk). In other words, if someone is worried about rhabdo from BFR, they probably shouldn’t train without BFR either. Nothing is without risk - the important question is “Does this INCREASE risk compared to traditional training?” The answer there appears to be no. That is why physical therapists, strength coaches, and sports scientists across the globe are utilizing BFR on a daily basis with their patients / clients.

[@karlmack8343]

I really like this format. I’d love to hear your thoughts on continuous glucose monitoring led nutrition vs grams of carb per hour as this is making all the headlines with CGM athletes performing so well in triathlon in particular.

[@TrainerRoad]

Great suggestion! We'll add it to the list.

[@ArtOConnor]

Promising protocol for sure. We have been using it for some time now in our gym to rehab after injuries with great results.

[@TadeuszPiszel]

I concur - great for rehab after injury. Anecdotal evidence here - tested it on myself, right PFJ instability with some chronic cartilage damage - right quads is 30% smaller than the left side for over 20 years. 8 weeks of home based BFR program with low intensity exercises for 35min 5x/day (as per ACL BFR rehab paper) and the result was quite impressive. Approximately 1cm thigh circumference increase on BFR side. I'm planning to repeat a similar program again (now 12 months post first training) this time for both legs.

[@epicsportsmarketing]

coach - I am very curious to what you would prescribe a cyclist using TR

[@driesvandenbroecke1697]

What paper? Let me read it pls

[@trbeyond]

Lots of complaining here but this seems to be a pretty well balanced analysis of what is known and not known. He says at the end that the priority needs to be consistent training. BFR “may” be helpful “if” implemented correctly.

[@benmiller388]

Is it 9% up against the same workout block or a before and after ?

[@TrainerRoad]

It was a randomized controlled trial that saw those improvements after implementing Blood Flow Restriction Training for the intervention group. Both the control and intervention groups completed identical training. INT group applied the cuff exclusively during low intensities and accumulated roughly 60min/week with the BFR cuff applied. To assess endurance effects, they performed a spiroergometric ramp test (VO2max; 30-40w/min increase) on a rowing ergometer. VO2max improvements for CON group were +2.5+/-6.1% (ES=0.3) and +9.1+/-6.2% (ES=1.3) for INT group. pubmed.ncbi.nlm.nih.gov/31672481/

[@davidhagan691]

I use it and the 1 thing I had to learn is that the fatigue induced the days after BFR training is significant.It is sneaky in that you don't feel it much unless you do high intensity, like a race. I did it the week leading up to a race and felt fine until trying to go hard and I just didn't have the ability to go hard for any appropriate duration of time.

[@TrainerRoad]

Great insight, David!

[@benmiller388]

OMG!!!!! DYLAN JOHNSON IS IN YOUR HEAAAAAAD! Rent free.

[@kdevine321]

while trying to recover from a rotator cuff surgery using BFR to do ultra light bicep curls, I had the idea that it could possibly be used in my morning runs with my dog. I run 2 miles with her M-F, but she is very slow ~ 14 min/m. So I usually strap 3lb weights to my ankles to keep me slow and build hip flexor strength. But then I realized I possibly could do this with BFR and it would feel like I'm at mile 18 every morning! This could really help lactate flush development while only running 30 mins a day. Probably will start out doing it once a week and build up.

[@longfermudd]

Interesting to see this covered in the context of cycling. There’s been a fair amount of discussion on this in strength training. Like the format.

[@ronwolfept]

A great modality we use during the early post-op rehab process utilizing BFR units with surgical grade cuffs and continuous monitoring of arterial flow to achieve appropriate limb occlusion values for the given protocol. Very safe when used with appropriate protocols and with specifically designed equipment.

[@nationsnumber1chump]

huh, I usually just put on my TT suit. Seems tight enough to me

[@AlexPeka]

Come on TR, no need for sarcastic click bait thumbnails. Your content has value and doesn't need it.

[@joshuasampson6971]

I agree

[@furyl1_neverz91]

Poor John

[@mikemallon4620]

Not clickbait if they show it works

[@MrPilberg]

I wonder if BFR could be replicated by shortening recovery periods in regular intensity workouts? The accumulated by-product from exercise still needs to be shuttled out the muscles, so maybe a side by side comparison of the effects of a shortened recovery session vs BFR session?

[@lereveure]

seems to me there's a lot that can go wrong here.. there's a lot of variables and conditions to think about.. not sure I would start something like this before more long term studies supports the current claims..

[@donadams5094]

Very different mechanisms involved, but there is at least some overlap between this and the hypoxic intervals pioneered by Doc Councilman with his swimmers in the 1970s. I’ve never quite figured out how to use them in my own workouts, but I am interested for sure. This may be a different route to some of the same outcomes.

[@themediocremtber4218]

Big smooth brain vibes here. Can’t believe you guys are advocating this.

[@shakinwakin35]

I’m here for the thumbnail this go around 😄. I appreciate the tongue in cheek since it’s unexpected from y’all.

[@Mapdec]

I have been trying this and monitoring with Sm02 and Vo2, it is incredibly difficult to maintain consistency, and there is a point in a steady VT1 ish workout where ThB starts to fall rapidly and vo2 climbs. It takes a while longer to RPE and pain to register. On release ThB floods but doesn’t bring the expected raise in SMO2 with it. It feels pretty scary. I think there is something to BFR in the early stages of a workout, but after the warm up. Still just experimenting and seeing what it does to my numbers. Not an advocate in anyway, just a curious coach.

[@TrainerRoad]

Thanks for sharing your experiences!

[@kenocontreras]

Incorporating BFR into my cycling training scares me a little bit. I found it ok in weight lifting because the time between sets with BFR is minimum compared to doing a 1 hour on TR with BFR

[@TrainerRoad]

The current research does not advise doing an hour workout with BFR, but rather incorporating it into portions of rest intervals, or for portions of low intensity workouts.

[@NukaCub]

Thumbnails gotta go. Y’all are way above the clickbait

[@sportbikejesus]

This thumbnail isn’t clickbait. At least not in the derogatory sense. There was no deception. Sensationalism to get clicks (as long as the content delivers what the thumbnail advertises) is all good.

[@jordanrundell9962]

This is so crazy. Everything you usually read on improving performance, is always to maximize blood flow. Stretching, foam rolling, heat therapy, cold therapy. All work to promote bloodflow. Usually, the consensus is more blood flow = more oxygen / vital nutrients = faster recovery = more performance. Then here comes a guy WAY out of left field and says, "NO! LESS bloodflow = more performance!" (Btw, not saying your wrong, just noting a peculiar opposite in training principles).

[@jblah1]

BFR will reduce performance while using it. It makes it more difficult so your body has to adapt. When not using it you’ll have gained the benefits of the adaptation. Similar to altitude or heat training. Once your body adapts to the added stresses you’ll have more blood flow when in normal conditions.

[@meatmotorendurance]

It would also be interesting to do a comparison of BFR to increased volume of aerobic work and/or to increased interval time above LT2 in terms of cycling TT.

[@krissche1863]

My question: is this safe for people with varicose veins? I have both deep and shallow vericose veins that are sometimes painful. I use compression socks and tights to relieve problems, so going the opposite direction and restrict blood flow for gains sounds unsafe. FYI: No I am not old, obese or inactive. I am 37 (got the varicose veins as an active, not obese 24 year old), lower BMI but within normal and I do as much training as I can and it is every day, just not very much every day.

[@BoondockStryker]

Wow me 2 in the podcast coach chad says not to use them with varicose veins. I've also had to start taking low dose aspirin since I started TR. I was getting superficial blood clots. It took me a long time to figure that out so if it starts happing 2u maybe this will help.

[@krissche1863]

@@BoondockStryker thank you for sharing, and knowing that someone else struggles with the same thing helps. You do the best you can with the genes you were dealt. How would the veins look if we didn't try to stay active?

I'm no medical expert, but this just sounds asinine to me. What you're basically doing is putting a tourniquet on your legs while your body is under stress. This can't be good for the body restricting blood-flow like that. In an attempt to prevent yourself from bleeding out, fine. For fitness gains, no. Just freaking ride your bike, and enough with listening to these ludicrous studies.

[@themrtimmyboy]

Seems dangerous to me. What is risk of blood clots?

[@TrainerRoad]

No research has been published about correlation or causation with BFR training for endurance athletes and blood clots, so that is currently unknown. That said, it's a very valid concern and should be seriously considered before implementing BFR training (as stated in the video).

[@themrtimmyboy]

@@TrainerRoad Thank you for your reply, and for all your work! Love the show (videos and Podcasts)

[@fitoldgit]

Very poor review. Why NO mention of BFR's documented benefits/increases in circulation (eg increases in vascular endothelial growth factors), nitric oxide, growth hormone, testosterone and so on? Presume you just looked for papers specific to cycling (comparatively very few). It's not just "fuel" delivery and removal of "waste" products that is the target here, but delivery of oxygen/02 to working muscles. When the new bloodflow/haemoglobin sensors become commercially available later this year (2023) we will see an explosion in the use of BFR tech. And "muscle toxicity"? Wtf? Complete mis-application of the term.
