[@stevespyder]

Fully agree with this. When I was a young teen, I was small and light and had mostly endurance, but as I aged and finally hit puberty, started doing strength workouts, I built muscle and speed. Now I try for a balanced combo as a Master Track + Field athlete for multi-events. Both throws and regular pentathlon.

[@youngsuit]

similar situation. i thought i just "wasn't fast" but when i started doing a lot of plyometrics, i realized it wasn't all just innate

[@Lightybruv]

Any tips to balance both fast twitch and slow twitch ?

[@stevespyder]

@@Lightybruv Plyometrics to build those fast twitch, 800m and longer runs for slow. Now you can not change your body's percentage of each, that is genetics, but you can build each type bigger depending on the exercise. Some sprinters with high percentage of fast twitch, will never be able to last for a marathon because they just don't have enough slow twitch fibers and vice versa. I think I'm lucky enough to have a natural balance of both which is why I can do multi events, sprints, jumps, throws and just enough endurance to last a mile. I can still do a 5k in 30 mins at age 62 but that is for fun or slow run training, that is not a competitive time even at my age.

[@trulykenji]

Im in this same situation. So if I start doing lots of workouts where I have to be explosive will I also be fast

[@dennisrobinson8008]

modern knowledge and old knowledge even said that there was a conversion from slow twitch to fast twitch and vise versa depending upon how you train and how you live. In the old days it was said around 20% can be converted. Modern wisdom is that over 50% muscle type can convert.... What it means is guys who started out with 20" vertical jumps can have 50" vertical jumps with the correct training and there are documented cases of this over and over again. Also in speed people build up speed over years. The best started young and kept getting better. IF you started later you need to put your time in. There are plenty of big name sprinters who are pros who started out middle of the pack in speed. It takes time and the right training. It's all been done before. Even on youtube. @@stevespyder

[@martinh5402]

Thanks Dane as always a great perspective on how to train for your sport/discipline. As a previous researcher and an S&C coach for the last 25 years. There are some confounding variables related with the research. Top bodybuilders are that way mainly because of genetics and not their training modality as 2X are the most hypertrophic of fibres so they have more of them naturally so are capable of becoming elite in size. Type 2a are well researched as fibres that, depending on how you train them, can go either more oxidative (endurance qualities) as they have good Mitochodrial mass or more strength & higher rates of force development (RFD) qualities because they have relatively large axons innervating them and high Myosin ATPase activity. 2X fibres have the largest axons and high ATPase activity without training at all so have the highest RFD you can achieve and clever studies have attached 2X axons to type 1 fibres and voila you have a poor mans type 2X fibre. The Russians did a study in the 80's on two 10.7 sprinters being trained into running sub 2.30 marathon and the fibre changes that ensued which was interesting (poor subjects).

[@michaelanthony4750]

I have been doing this for the last 10-12 years.. I have always been extreme explosive from birth I also did jumping sports and throwing until I was 30.. But as age started to take over I decided it was time for a New challenge. So as any strong heavy idiot Triathlon seemed like a good idea .. First time I jumped on a Bike I maxed out at 1600watts in a spinn class but I had 0 endurance Now 10 years after I max out at 1200watt witch is high for my age but my endurance is way better it still sux compared to the pure endurance people but deffently got better.. So just to add on to what he is saying I totally agree you can change stuff but it will take time and allot of it..

Great topic. Old guy here. I am starting to wonder about the efficacy of slow steady endurance work for most of the population. The Strong First Group and it’s founder, Pavel Tsatsouline, claim that Soviet research combined with their own experiments indicate that short bursts of maximal effort (5-10 second) separated by 25 to 50 seconds of rest (a 1:5 work to rest ratio) lead to strength, hypertrophy, and endurance improvements. These endurance gains are just slightly less than those of subjects who go through steady state endurance training. Any thoughts out there?

When you talk about shifting, are you talking fiber number or mass percentage. Back when I was racing intensely, we talked about power training increasing the size of 2x fibers but not the number (and,we were taught that the same held true for all fiber types.) And, does it matter whether you are talking number or mass percentage?

[@krane15]

@@GavinWilliamson13 Have you seen any 6'6 gymnasts lately? No amount of muscle type can overcome that kind of limitation. I remember watching an interview with a Chinese Olympic trainer. Because the Chinese consistently win in diving, they asked the coach what he looks for in choosing candidates. He said, body type, e.g. upper body to lower body ratio/ build/etc. His philosophy was that he could teach everything else needed for them to be a champion. But he first needed them to have the right physical build/type. That's the one thing he couldn't correct.

[@slydog7131]

Do muscle fiber types actually shift or does one type undergo hypertrophy while the other does not? Do the biopsies identify the number of FIBERS or simply the VOLUME of each type?

[@gunnerjax9012]

Very confused as to how this applies to wrestlers. Because we need to be powerful and explosive for a relatively short amount of time, but also endurance is pushed so much in the sport?

[@EA-iq3dv]

Is it contrast training specifically that resulted in that fiber shift referenced? Or can independent exposure to both of those same stimuli in a given time/same workout, etc. cause a similar adaptation?

[@Yupppi]

As far as some studies go, resistance training (no matter if light or heavy load) will result in the growth of both fiber types at least. To me it sounds very common sense that you can't change the ratio of your fiber types by training both extremes simultaneously, like how would the ratio change? But you can grow both and it's suggested that we have a lot of hybrid fibers that have both kinds of myosin heads and that they would change depending on the training experience increasing. Typically the issue with doing resistance training and cardio in the same session is that they can interfere with each other (the first one drains energy and hurts stimulating the second one) and should always be separated if you have any goals in performance for them (walking isn't particularly disrupting as a side note, but doesn't probably lead to great adaptations either, other than help with body fat % and digestion, walking has been shown to improve body fat % even in trained and very active athletes). Like you won't see a big and muscular long distance runner, they eat enormous amounts of food to fuel their training and they couldn't possibly feed and recover enough to build muscles as well, the body just has its limits when you push it for specific performance enough. Of course a beginner can gain all, endurance, strength and muscle size just because they have plenty of resources to get better at each, they improve from almost nothing at the base line. Once you reach a certain level in each, you need to dedicate more resources to improve at all and that's where you get the issue of having to specify both in training and adaptations. But until that your body has some amount of resources untapped and just waiting. However, we know that you can build muscle with higher rep ranges which usually improves your fitness in the context of those exercises at least (being able to do more reps, not necessarily very effective for cardiovascular improvements). Despite that, the loading of the exercise doesn't seem to change the ratios of fiber types compared to the general population other than lowering the amount of type 2X (in bodybuilders and powerlifters), at least based on studies like "Muscle fiber characteristics of competitive powerlifters" by Fry et. Al, 2003. The type 2X literature seems to be rather unclear. Some study proposed that the bodybuilders had up to 15% type 2X and general population control group had only 5% (to which garage strength is possibly referring to), but for example the previously mentioned study (and a couple of others, for example studying olympic weightlifters) reported lower than 2% for trained athletes, while the general population control group had slightly above 12%. Completely opposite cases. Furthermore getting a well presenting biopsy seems to be one of the challenges just as well, you could only be certain with a dead body where you could freely cut the muscles and calculate the fibers. There's actually a really fascinating episode of Iron Culture Podcast (hosted by Omar Isuf and Dr. Eric Helms) where they have Drs. Brad Schoenfeld, Brandon Roberts and Juha Hulmi talk about hypertrophy and answer how do the muscles grow, the current understanding in science. They also touch the muscle fiber sampling and its difficulties. Another good source is Stronger By Science website (and MASS, monthly reviews of studies in strength sports) where Dr. Greg Nuckols wrote an article about fiber types and training in 2016, they also addressed what the scientific literature can tell in the podcast with the same name in 2022. The biggest takeaway as far as I understand regarding muscle fibers and training is that you can't know your fiber type ratio (very often the ratios are close to 50-50, varying by the muscle in question and also the individual) unless you go to a lab and have a biopsy in all your muscles you want to train, and since your goals are probably unrelated to your fiber types (say you wouldn't change from lifting weights to running marathons just because you learned your fiber type ratios are very slightly to one direction), it doesn't really matter. And more than that, when training with weights grows both fiber types and that your load/rep ranges can't meaningfully change that, it doesn't change your resistance training either. And if you're a runner, you train running and with that there's not too much left for resistance training goals. You're best set training for the specificity of your goals, for example an athlete needs to train their sports skill as well as their strength, while a bodybuilder is more focused on just growing the muscle size. Olympic weightlifters do a ton of skill specific work, but the skill contains pretty heavy weights and a progression towards peaking strength. It expresses power a lot so they do train the explosivity a lot and the training does require some decent fitness, but they also take long rest periods because they can't sacrifice the skill for fitness since they specifically need to express the technique and power. And as said before, if you're not that experienced in all fields, you can usually reach a certain level in each before you hit a wall. The fiber types are sort of red herring where people thinking about them too much unnecessarily distracts them from good training that they would've intuitively done towards their goals if they didn't know about the fibers to begin with.

i will share a bit of my climbing knowledge because i guess it might fit for the first example. when you have a high maximum strenght (e.g. high jumps) you will not fatigue as fast in a moderate action (playing normal basketball). there is something thats called critical force, which you can do even after you feel completly drained. the gap between max and critical is not so big for pure endurance athletes, but when you have a high max your critical force will be evenly high as well. in climbing it's ~ 30% of your max strenght. maybe check the lattice training fitness check for more informations.

We meet again time to helpppppp. You don’t need to do box jumps at all there are tons of different plyometric exercises for different reasons.

You can do box jumps by jumping on top of anything STABLE if you can’t find anything you can just do jump squats or jumping as high as possible and as soon as you land explode off the ground again.

According to Andy Galpin. It's only the hybrid firbres who can change. Every one has a certain amount of hybrids. And there is NO training that will increase type2x.
