I was reading an article in MuscleMag about Fast, slow and intermidate twitch muscle fibers. It talks about the difference between the three and what is the best way to gain muscle mass. It says one of the differences between bodybuilders and strongmen is the fact that strongmen lift really heavy to the point where their muscles aren't doing all the work and their nervous system takes over.
"As the load increases beyond the moderate range (50-60% of maximum), the nervous system discharges more frequently and the muscle fibers respond with greater increases in pulling force. So the entire time you were lifting weights exceeding about 60% of your maximum, thinking you were activating more muscle fibers, you were actually taxing your nervous system's energy reserves."
Whereas, with bodybuilders they want the muscles to do ALL the work. They say that the best way is to involve all of the muscle fibers. The article says
"that 90 percent of all available muscle fibers will be activated at a load of only about 50% of your maximum....forcing you muscles, tendons, and ligaments to the point of disaster - to fully stimulate all of your muscle fibers into growth. Volumn is the key to stimulating the muscle to develop and grow. A greater volumn of work for any given muscle is achieved by increasing both sets and reps of each specific exercise. Reps should probably never fo lower than 12 and could go as high as about 25 per set."
It mentions that if your goal is to get stronger, than low reps heavy weight is the way to go....but if your goal is to gain size and develop your muscles, than high reps moderate weight is the way to go.
Does anyone do this type of training? If so, have you gotten good results?
