"Doing more exercise with less intensity,"
Arthur Jones believes, "has all but
destroyed the actual great value
of weight training. Something
must be done . . . and quickly."
The New Bodybuilding for
Old-School Results supplies
MUCH of that "something."

I'm not familiar with what you're asking.

Dr. Darden,

The information on Titin.

The article about Titin is interesting. I'll need to read it several more times to be able to discuss it. And the drawings are noteworthy.

I talked with MacMillan three or four times. His Negator machines are less productive than the ones from X-Force, at least in my opinion.

Thanks for including the material.

I would like to see Dr. Michael MacMillan MD post here on Titin and eccentric training. Thirty year of eccentric training experience should be very informative.

The application of the knowledge on Titin might end the practice of plyometrics.

Muscle cells produce phosphatidic acid during eccentric contractions which activates mTOR, the master enzyme responsible for muscle hypertrophy.

https://www.ncbi.nlm.nih.gov/...pubmed/19470781


Myokine IL-8 may be released more during eccentric exercise. RIP Arthur Jones, myokines have shown that the "indirect effect" is a real physiological occurrence within the body.

Muscle fibers - slow and fast twitch muscle fibers release different myokines. Thus, aerobics and weight lifting may offer different physical benefits. Can you hear the laughter, ALL of you anti-aerobics zealots?

I'm sure Edwin "Truck" Brown would agree with your assessment of the X-Force machines, with his 20 1/8 inch left arm measurement in only 4 workouts during 2 weeks. His left upper arm contracted went from 19.5 inches to 20.125 inches in 2 weeks. No drugs....Lots of food.

The best I've ever done in 2 weeks was 3/8 inch on negative-only rest pause.

Jones did not use drugs and he looked pretty good at around 50 years of age

---Scott---
Maybe if he hadn't lifted in quite a while and his arm was still 19.5 and then he jumped on those machines and ate a ton more food would his arm go up that much in 2 weeks. Like in Colorado .

Mr. Brown does have superb genetics. However, it is a sad commentary that PED's have been involved for so very long in bodybuilding. Misuse of drugs is a very serious problem.

The insulin sensitivity of a young (19 year old) Casey Viator was most likely very high. With insulin's anabolic nature, and with Casey being very lean was of great advantage to optimal insulin sensitivity. That is one of the reasons carbohydrates are necessary in an anabolic diet, not to mention a protein sparing effect. I'm sure some athletes are misusing insulin sensitivity drugs.

Bodybuilding is certainly not as popular as once, but vanity surely is. Plus, supplements advertisements have never been as sophisticated as today. Caveat emptor.

After looking at various exercise
EMG's for a while now, it seems heavier loads illicit much more muscle activity. Different movements that recruit the same muscles, don't vary percentage activity levels very much. In other words, chin ups, rows, and pull ups recruit the same muscle in similar manners to more or less similar degrees. Trainers (gurus) will not admit this, as variety is way over stated.
