the muscle fibers

[DOtrainee]

Dear John,

Just out of curiosity, is there a difference in the different types of muscle fibers (slow twitch/fast twitch) being worked with the different exercises (power cals, DVR, DSR) offered through your program? Do those fibers change with the amount of repetitions done in DVR/DSR fashion? I was just wondering if the different exercises inherently worked different types of muscle fibers, which can be utilized for specific functional capacity.

Hey powerflextrainie,

There are any number of exercises that one can use to maximize "Fast Twitch" muscle fiber. For instance, my sprinting program does exactly that. And certainly one can perform any number of our exercises at various rates of speed for the purpose of enhancing "fast twitch" muscle function. The one type of exercise that I do not recommend for the purpose of enhanced fast twitch muscle function is "Plyometrics". Not because "Plyometrics" are not effective, because they most certainly are. But rather because Plyometrics are very damaging to the joints.

Bottom line: certain types of exercise are great for increasing specific function as relates to sport but very little else. I am far more concerned about improved cardio function, improved joint function, and creating a strong, beautifully balanced and aesthetically pleasing physique that can be maintained for one's entire life.

i know your question was about fast and slow twich muscle fibers but it souds like you were asking about reps for certain muscles heres what i recommend. if not then ok cool im sorry. anyway for me i find that with DSR's i do lighter tension and higher reps for shoulders and bicepts and get better results. where as chest and tris i do moderate to heavy tension more often and i get good results, back is pretty much only pullups for focus exercises.i also do my pushups and TBS of course. this is what works for me.if i misunderstood your question im sorry if not i hope this helps.

the thing about weights is the negative impact on the joints. the thing about plyo's is the negative impact on the joints.hummmm. now i will do plyo's on occasion but notin high repsorhigh sets and not often. thats just me.the shoulders especially takea pounding.again im just a guy and this has been my experiences.

Thanks for the responses, but I was really trying to get a different piece of information. My previous post really doesn't do a good job of asking what I wanted. My apologies gang:

Here's what I was really trying to get to the bottom of:

I've been practicing the M7/DVR along with some power cals for the past 3-4 weeks. I notice fatigue in my muscles with each type of exercise, but the overall feeling of the muscles after different types of stimulation is...well...[I]different[I].

When I do DVR exercises, I feel fatigue after the first set of 10 reps. When I start the second set of exercises, from the first rep onward I can tell I'm working with pre-exhausted muscles, and it takes a greater deal of effort and concentration to push through and work the muscles intense enough to get the results I desire. By the time the third set rolls around, I'm usually quivering from the first attempt of tensing the muscles. The last 10 reps of that third set become a battle against my exhausted muscles and my withering willpower to force my muscles to flex and resist. That last set, when completed, leaves my muscles tired, resistant to stretch (just like the weight lifting days), and very pumped whether I do tension in one direction or both. 3 sets of 10 reps of the M7--when done correctly--is an intense workout, and let no man speak otherwise.

The next day after such exercise, My muscles will usually have a tiredness to them. Not like delayed onset muscle soreness, but a feeling of exhaustion, like they've been overstimulated by the nervous system to do more work than normal. That's really the only way I can describe the after effects. It's like I wore out my nervous system, and the muscles are hesitant to rush into such intense stimulation. Occasionally my muscles will be sore the next day (with DOMS) but it's not that common.

HOWEVER, to supplement my results I've been doing pushups, sit ups, and TBSs to enhance my results, and because I'd like my body do to high reps of pushups, squats, and have better abs. So I've been doing 10 sets of each of these exercises, keeping the rep limits to the first sign of diminished technique.

When I do pushups like this, after one set the muscles feel tighter, more pumped, and the next day after 10 sets tend to be sore. Sometimes if I over do it they can be sore for two or more days. With these things in mind, here is what I'm pondering:

Do my muscles feel different because the pushup is a more intense workout, or if I did just as many sets and reps with a DVR bench press or full range pectoral contraction would I have the same type of tension and soreness in the days following? Or...could it be that the pushups stimulate different muscle fibers that aren't as intensely stimulated with DVR, and could that result in the different type of stimulation/soreness???

This is the can of worms I was trying to open. Sorry for being so vague in the first place and leading you guys down the wrong path. Others feel free to impart wisdom, especially VRT Man since the majority of his workouts consist of DVR/VRT exercising.
