sorry but i cant agree with this,if your in a surplus and your not gaining,then your not really in a surplus ie you've either miscalculated your maintanance level(easy to do) or you've misjudged the amount of activity you do,ie just walking around moving etc.There are humans who at times and for various reasons do not have an increase in weight or lean body mass accompanied by a significant increase in caloric consumption. .
Also Lol - Since I finished HST I have used a significantly different program and and my waist measurement has gone down as has my bodyfat % with increases in chest, thigh, and hip measurements while taking in about 1800-2400 calories/day. Nutrient ratios about the same as above paragraph. For what its worth to you Lol, I have never grown on the amount of volume in this program. For me the volume is "low" and all the workouts extremely easy. We could go on and on about what happened in my HST experiment, but I am confident each person is far more interested in their own experiments and this site better served to move forward beyond my invidual case and experiences with others. Next.
Increase volume if:
You are never sore
You are never tired
You are not growing
Maintain volume if:
You are slightly sore most of the time
You are tired enough to sleep well, but not so tired you lose motivation to train.
You are noticeably “fuller”
Decrease volume if:
You are experiencing over use pain, and strain symptoms in joints and/or muscles.
You are tired and irritable all the time, yet don’t sleep well.
Strength levels are significantly decreasing.
So yes, there is "a point of growth/no growth". That point is determined by the Load, the Volume, and the level of Conditioning of the tissue. To understand this we have to look at what has to happen to the muscle during a workout in order to get it to grow.
In order of importance:
1) Satellite cells must be activated, differentiated, and fuse with existing fibers, donating their nuclei.
2) Mechanical stress must be transmitted to the sarcolemma (mechanotransduction) and contractile protein structures within the sarcomeres. This will trigger focal adhesion kinases (FAK) that in turn initiate the downstream signaling events leading to an increase the contractile and cytoskeletal protein expression/synthesis.
3) pH and oxidative stress must be acutely increased within the muscle fiber.
Focusing just on the workout, this pretty much sums it up. If #1 doesn’t happen, you will not grow…ever. If number two doesn’t happen, you will grow a little, but you will soon reach the limits of the sarcoplasmic/nuclear ratio and growth will stop. If #3 doesn’t happen, you will still grow quite significantly, but the rate of growth might be enhanced or facilitated if #3 is achieved.
#1 is achieved when a certain level of microtrauma is experienced by the fibers. This is brought about by load, eccentric contractions, and to a much lesser extent, hypoxia (A.K.A. #3) When load, eccentric contractions and #3 occur, each fiber will produce and release muscle specific-IGF-1 (sometimes called mechano-growth factor) The IGF-1 in turn seeps out of leaky sarcolemmas and acts on nescient satellite cells to initiate #1. Microtrauma is rapidly reduced from workout to workout (Repeated bout effect) thereby limiting the effectiveness of any given load to induce further hypertrophy.
Bryan; Optimising HST said:1) Increasing volume isn't a bad thing. The only time it is contraindicated is when you can't handle any more volume because the current weight loads are sufficiently heavy and are causing sufficient trauma to the tissues with minimal volume and adequate frequency.
There is a false notion that HST is about “low volume”. This notion arose from people erroneously stereotyping HST as a previously existing “muscle beach” method used by guys in “the good ol’ days”. HST prescribes that volume be more evenly distributed over time to create a more constant environment and thus and more consistent stimulus for muscle growth. The volume of training in HST does not differ significantly from previous programs.
Nutrient ratios were 30-35% protein/65-70% fat (had 4 grams of carbs per day, save about 4 feeds with higher carb intake). Would a different ratio have made a difference? Perhaps. History had shown different ratios to be a negative for hypertrophy and lbm with me as an individual.
