Nice presentation! I almost want to submit my muscle for Bx. I've been WFPB for over 6 years and have been training on mostly my road bike for over 30 years. Significantly over the last 3 years. Training for high power output to go as fast as I can at age 52 with over 5000 mi this year and over 12,000 mi the last 3 combined. If you ever could use that muscle data I might be willing to submit my muscle for research if it could benefit your quest for knowledge. If you are ever interested you can see my cycling workouts on Strava, James Bennie. Keep up the great work!
Immense respect for you bringing science to the people. A question re: hypertrophy for weightlifting or other power/speed athletes. Some WLers do hypertrophy blocks using "bodybuilding" styles of training (high reps, slow movements to increase time under tension/muscle damage and, presumably, stimulate more growth in muscle size). They will then follow with strength or power blocks with idea of converting increased slow twitch muscle mass to fast twitch fiber appropriate for their sport. All good, but seems like this approach is first converting some fast twitch they already had to slow twitch during the "hypertrophy" block and then back to fast twitch. Isn't there a more direct route to building more muscle that is fast twitch in the first place? Isn't there research suggesting you can get same or similar size gains from heavier wts in lower rep ranges that are more sport specific to WL without going through this roundabout detraining and then retraining tissue? Since you train MMA and other weight-class athletes who want to get stronger without increasing size/weight, what would you do differently if you have a speed/power athlete who wants to go up a class without going through the counterproductive process of "bodybuilding" described above?Thx.
Thank you for your presentation. Nice job. It helped me to understand some methodological aspects of the studies. Do you think that Schiaffino Paper´s called Fibre types in skeletal muscle: a personal account may be a good reference for the fibres clasification? Regards.
THANK YOU SIR FOR SUCH GOOD CONTENT...SIR DID YOU NOW FIND ANY SPECIFIC EXERCISE TYPE THAT CAN PROMOTE (FAST TWITCH) MUSCLES GROWTH???.....AND ANY WAY WE CAN HAVE MORE FAST TWITCH MUSCLES??? PLZ SIR🙏🙏🙏
hi andy, i am also understanding you to say that the type of fiber is totally controlled by the nervous system cell that is attached to it ? i am equating that statement with saying that a fast nervous system (the speed at which our impulses flow back and forth) controls our fiber type ? is this what you are stating ? if so, it would seem to implicate that speed and quickness are directly related. that each is controlled by the same thing ? i know, from my own personal experience, that this can not possibly be true. for i am quick as a cat, and slow as a turtle. if we are talking about moving a few steps versus a 50-yard dash. i am having this same conversation with a friend of mine. i think my quickness comes from a fast nervous system, and this has nothing to do whatsoever with my muscle fiber type, of which i have tons of endurance and no speed or much strength. so obviously i have a good amount of type 1 fibers. and not much fast twitch.
what if the level of danger the brain perceive leads to development of fast neurons which turns the fibers to fast fibers eg. the mma fighter or the in active person doing an unpredicted sudden heavy load activity
Great video, I was just wondering if there was a reason why that soccer players have more slow fibers as it’s a anaerobic sport, much like MMA in the sense that you repeated he bursts of energy however over a long time, the only difference is soccer is more lower body dominated then MMA, however as shown by the study the MMA fighter had 70% fast twitch which is very different to the more slow twitch soccer players?
There are multiple variables that could determine that. Which muscle they examined The type of training the athletes do, soccer athletes usually do a lot more aerobic training than MMA fighters, especially if you go back to a couple decades ago. Also MMA has more of a full body engagement with fast twitch fibers, while soccer players are mainly producing maximal efforts while running and jumping. MMA fighters produce maximal efforts when they sprint for a takedown or defend from one, when they wrestle and have to block the opponent's movement, when they grab the opponent and spin him around on the ground, when they throw powerful kicks, punches, elbows, knees, when they jump for high knees...there's a much larger volume of work being done by the fast twitch fibers I think, especially during performance
hi andy, i simply do not think that fiber type changes anywhere near as much as you are positing ? if a person could really change his fiber type with that sort of significance, we would know about people who have done it. name me one sprinter who is now running the 5k ? or one 5k runner who is now a sprinter ? or give me anyone famous who made a change from being good at an activity that typically requires one type of twitch to an activity that requires the opposite type of twitch ? i do not know of anybody that i have ever known who has done this. you are quoting studies. but depending on the time of the study, it shows different results. but at each point in time, those individual studies were probably thought to be totally correct - cuz that was the pinnacle of their knowledge. if you want to posit the conclusion that fiber types can change significantly, then i want to see examples of real people who have done this, that the two of us can verify. not someone in some study that neither of us knows anything about.
You won't see anyone famous who done this transition because if they're famous for being a sprinter or endurance athlete, they obviously not gonna want to change it. Whole process takes long years. That would waste their careers for no apparent reason. You present anecdote based, extremely unscientific approach which leads nowhere.
I think being a good sprinter is more than just fibre type, bone structure, lactic acid formation stuff like this affects whether you can be a good sprinter or marathon runner, so if a good sprinter was to convert to slow twitch, all these other factors probably would been they wouldn’t be as good marathon runners
Excellent presentation! Thank you for taking the time to share! Have you thought of physical/training tests to approximate type?
Thanks so much - incredibly helpful and answers questions I've had for years

I'll keep this in mind :-)
Great mission to keep us state of art Andy
Awesome presentation!!! Thanks Dr. Galpin

Thank you for these videos, have any of these questions been answered now?
And have you ever done studies on Rowers?
Thank you for your presentation. Nice job.
It helped me to understand some methodological aspects of the studies.

PLZ SIR🙏🙏🙏
How can we tell what muscle fibre types we have ? If we had this knowledge could we optimize our training for it in terms of hypertrophy?

Shouldn't the slow twitch be black and the fast twitch white?

what a lame comment. start a study and figure it out!

@@MrTas44 i agree with that. but muscle twitch plays a tremendous role.
@@michwoz i am very scientific. i want to see someone that we can VERIFY that has done this. in case you dont know, science is all about verification.
