As far as research tells us, muscle growth is caused by the combined effects of high levels
of mechanical tension and increased metabolic stress, with muscle contractions during resistance training as the third most important contributor to anabolism.
Umetsu, D., Aigouy, B., Aliee, M., Sui, L., Eaton, S., Jülicher, F., and Dahmann, C. Local increases
in mechanical tension shape compartment boundaries by biasing cell intercalations.
Metabolic stress is one of the three mechanisms of hypertrophy, together
with mechanical tension and muscle damage, so you definitely want it as a factor in your training plan.
By contrast, in graphene, similar fiels have been induced
by mechanical tensions or defects in the way the carbon atoms are arranged in the one - atom - thick honeycomb lattice.
Other exercises which fail to create
high mechanical tension also limit the weight that you can use, such as the triceps kickback, thereby preventing you from making any noteworthy gains even further.
For strength pursuits, we want less metabolic stress, and
more mechanical tension, so the total TUT to build strength is lower.
And conversely, when pursuing muscle, we want more metabolic stress and
less mechanical tension, so total TUT is higher.
Jason teaches us the importance of rest periods for max gaining, specifically for total body and isolation exercises, and how this
impacts mechanical tension in the muscle.
It seems likely that the greater and more even EMG amplitude during the movement performed with elastic resistance might
enhance mechanical tension and thereby increase hypertrophy.
The great thing about set extenders is that they let you combine different exercises that stress different parts of the strength curve in one brutal package and thereby help you maximize hypertrophy by achieving a full range
of mechanical tension.
Identifying the molecular pathway leading from the Hedgehog signal to increased mechanical tension
This mechanical tension directly influences the elongation direction of the intercellular lumen.
This study reveals for the first time, that the interaction between cells and the ECM can control and direct
the mechanical tension between cells.
Recent physical approaches, including the ablation of bonds between cells using laser light, have revealed that
mechanical tension on cell bonds is elevated along this anterior - posterior compartment boundary.
If you're looking to enhance protein synthesis, you need to increase
the mechanical tension placed on the muscle, and this can be achieved by training in the following pattern: 5 sets x 5 reps, 120 seconds rest
According to the classic review article in the Journal of Strength and Conditioning titled «The Mechanisms of Muscle Hypertrophy and Their Application to Resistance Training», to signal hypertrophy, you must manage three crucial mechanisms:
mechanical tension, metabolic stress and muscle damage.
But what if there was a way to extend
the mechanical tension during an exercise so that it stays more or less equally intense at all specific points of the range of motion?
To maximize its benefits, keep your form in check and aim to keep
the mechanical tension constant.
To maximize muscular growth,
the mechanical tension has to be high (meaning that the weight has to be heavy), long in duration and consistent.
The first and primary stimulus for muscle growth, however, is
mechanical tension — there can simply be no hypertrophy without a high level of mechanical tension throughout the entire range of motion.
By definition, there are three hypertrophy mechanisms:
mechanical tension, metabolic stress and muscular damage.
It is common knowledge that
the mechanical tension associated with resistance training stimulates hypertrophic gains — that's why we lift heavy weights, right?
Muscle tension can be described by
the mechanical tension placed on the muscle during an exercise, muscle damage by the eccentric load causing micro tearing and initiating the inflammatory response, and metabolic stress as a result of the buildup of various metabolites such as lactic acid (3).
The mechanical tension is directly related to intensity of the exercise, which is the key to stimulating muscle growth.
Mechanical tension, muscle damage and metabolic stress are the three primary factors that promote hypertrophy from exercise.
-- Nutrients transfer Response to
mechanical tension: The body has to deliver those nutrients to the active muscles to provide them with sufficient energy to keep working out.
You subject your muscles to
mechanical tension with every repetition of an exercise that you do.
These are
mechanical tension, metabolic stress and muscle damage.
There are 3 mechanisms to hypertrophy and that's
mechanical tension, muscle damage, and metabolic stress.
The big lifts and their variations are great for creating high amounts of
mechanical tension — bench press, chin - up, row, military press, deadlift and squat.
