Different Definitions of Intensity

I was recently questioned about the various ways I defined intensity. This was originally written on August 5th, 2004 on my Clinical Exercise Tech Yahoo Group / Email list. Read More...

Exercise and Genetics Reboot

When I wrote the original “Exercise and Genetic Variability" presentation / lecture for the 2006 High Intensity Training Seminar, hosted by Bo Raily in Indianapolis, the information presented was ground breaking. Read More...

Resistance Exercise Reverses Aging in Human Skeletal Muscle

The following study is one of my favorites to discuss. The name says it all and is extremely powerful. Usually, scientists are very measured in their wording. You may see a study with a name such as this:

Eur J Sport Sci. 2016 Nov;16(8):1055-63. doi: 10.1080/17461391.2016.1185164. Epub 2016 May 27.
Effects of resistance training on expression of IGF-I splice variants in younger and older men.

Strength training stops the aging process in human skeletal muscle.

I was answering some questions for one our clients the other day concerning various forms of exercise / activity. I recalled this study, opened my laptop and started to discuss the relevant research with the her. This study, in particular, serves to illustrate the priority of resistance training. Read More...

Interview from the Land Down Under

I participated in an interview with Christian Marchegiani from Sydney, Australia. First of all, I would like to thank all of the people from Australia and abroad that like our page. This truly humbles me. Australia is a country I have always wanted to visit. Thanks again and thank you, Christian for giving me the opportunity to participate in the interview.


More on Inroad, Muscle Fatigue


“The inroad theory is just that...a theory.”

Honestly, I am not sure we can call the concept of inroad a theory, perhaps a hypothesis. As you know in science, "theory" is a strong word and requires much supporting experimental evidence. I am not knocking you for this. I really can't remember who's brain-child the concept of "inroad" can be attributed, probably either Ken, Darden, or Arthur. I know it is in the SuperSlow manual and logically makes sense. However, it is not compatible with the experimental evidence. Briefly, the concept of inroad is based upon a momentary decrease in strength - such that (as I remember) training with 80% of one's 1 RM would lead to a 20% inroad. As I stated before, this concept is too simplistic and not indicative of what is occurring physiologically at the cellular level when you apply a stimulus and cut the sucker open to see what happened.

Inflammation, Recovery, Skeletal Muscle Hypertrophy

Doug and said:

“I am not sure what to make of the study from the article about it. With 36 subjects total, it is unlikely to have enough statistical power to reach any conclusions. Their conclusion seems counter-intuitive to me. I will try to get the full text article to review.

Doug McGuff”


I read the full text of the study when it was first published some time ago, although I can’t seem to find it at the moment (I have 3000+ studies on my hard drive). Strictly from my recollection, I was skeptical of the results immediately. Not only was it contradictory to almost all of the previously published data, but the delta between the control group and treatments groups were huge (60% greater CSA increase in the treatment groups). I’m not sure we would see such a difference with anabolic steroids and untrained subjects over that short of a time period. Read More...

Sleep, Recovery, and Protein Synthesis


“I would like ask you some things about recovery:process of compensation and after supercompensation occour only when we sleep(maybe at fast rate) or even during the day?”

To answer this question completely would require major speculation on my part. As a responsible scientist, I try not to speculate very often. However, protein turnover is elevated during sleep. Also, when a muscle is working, it stops recovering / growing.
