Still helping people out! Well done for a short, yet extremely informative video
Makes so much sense! I feel more comfortable with lifting weights and sprinting. I like training myType IIx muscle fibers more. & i love how these videos are short yet informative. I'm taking an anatomy class right now :)

Actually you probably are using your IIa fibers. The body does not want to naturally want to use IIx fibers. It generally doesn't want to be used unless you were under some high physical stress.

@@lilbrocko yes you are, but it's not an all- in- one Fiber type relationship. The body will pair Type IIa and IIx together and so type IIx does not simple work in isolation.
Good job on your videos! keep up your good work and don't give up. I hope your videos gets the popularity they deserve.
This makes so much more sense to me now than when I read it in the textbook. Thank you!

brief and easy to understand.
I was always a sprinter as far back as I could remember, and sucked at long distance running. Now as an adult I took a DNA ancestry test, and among other things it told me, just as I suspected, that I'm fast-twitch dominant.
@futurez12

Me too, I have 2 copies of the fast twitch gene, but it hasn't helped me run fast, and if I were to choose one type of running that I think I'm best at I would've picked long distance. However, if I do exert maximum force my muscles do tend to fatigue quicker than most other people's. I don't know what to believe TBH.

Another great video! You forgot to mention that Type I fibers can't be changed into Type II fibers. And since the muscles in our body have more of one type of fibers than the other muscle groups (ex: calves are have more type I fibers than type II) you could make a video explaining that!
awsome video

*I have a question*, lets say you have been doing slow reps since you started or genetically speaking its possible you have more slow twitch fibers by default. You want to hit the type 2 a and x fibers with fast reps but they are less conditioned as a result of your training and/or genetics. If my understanding is correct then your ability to lift more weight is more dependent on your slow twitch muscles as they make up an unusually large amount of your power out put and thus you have a hard time lifting heavier weights fast in order to hit the other types. Like I said I'm not sure if the assumption of mine is correct but if this is why I have a hard time doing fast reps at heavy weights can I hit the type 2 muscles fibers better if I take the weight down bunch more notches and lift it faster? If not how can I get fix this? Perhaps its in my head, I just want the most I can get.

Robert Dicke lift moderately heavy with compound lifts short recoveries your tempo should not be fast but at a constant fluid motion while performing the exercise 8-12 reps 60-80% of how much you can lift is good start then try and go for 12-15 reps after a couple of weeks. Learn sprinting drills and techniques start incorporating them into your cardio routine hope this helps
@madabz81

Robert Dicke and one more thing, if you cannot perform compound lifts with good form you may suffer muscle imbalances and still may need a trainer to aide in instructing some corrective exercises not to mention foam rolling, stretching and knowing how and when to start and stop your deloads
i love you!! thanks for helping me understand :D

Thank you, thank you, thank you!!
you are awesome man!
Regarding the size principle: are the muscle fiber types recruited according to load (force) or to effort? If you hold a light weight in an isometric contraction, it gets harder and harder as time goes on-your effort increases even though the load stays the same. As you approach failure you end up recruiting all muscle fiber types. You drop the weight once all fibers are fatigued.

It's a lot of science-y stuff. Lots of cell activation. Things like proliferation and differentiation take place. Nuclei are added. etc etc. I would love to but I wouldn't know when I will have the time to break down a video like this.

Wait so every skeletal muscle has some of each fiber type in it? What does the distribution look like? So my bicep would have all three but more of the type II-x????

Well if u go to deep cardiac and smooth muscles are involuntary but both do not work on their own. Only cardiac muscles are autonomous (can regulate themselves) and smooth muscles are under the control of the ANS
Salute 👍
The more I learn about the human body the more I marvel about the astuteness and brilliance of the designer behind it, whether it’s God or Nature!
tnx mate
I feel like I got the understanding of this. And I would have to say my type are very equal. due to I am able to move pretty fast and my endurance is on par with it.
pls make a video on which is better to build leg miscles, squat or sprints.. thx
