Detta är ett utdrag ur en artikel som heter A Training Philosophy For Solid Mass Gain av Kelly Baggett
"Training Principles
Growth is stimulated from a combination of tension, total work, and fatigue. As we’ll see in a minute, outside the boundaries of extremely low volume programs, progressively increasing tension at a given level of work is the primary stimulus for ongoing gains in growth. Factors related to fatigue might add around 10% to that.
Tension
To get maximal tension on all available muscle fibers in a given muscle requires full motor unit recruitment in that muscle. This can occur 2 ways:
A: Lifting a heavy load (80%+) so that all the muscle cells are firing from the first rep. (example: Lifting an 80% load for 5 reps)
B: Lifting a light load in a fatigued state so that your muscles “think” the load is heavy. (example: Lifting: a 50% load with short rest intervals and having the weight feel heavier then your ass after a 5 mile run.)
Anytime you put forth a maximal effort and have to really strain to move the weight, regardless of the weight on the bar, all the muscle fibers in the working muscle turn on and “tense up.” This is tension. Get a muscle fiber to “tense up” often enough in a workout and it gets damaged. Your muscles don’t know how much weight they’re lifting, they only know they’re working. It's not necessarily the weight that induces hypertrophy but what the muscles "go through" while lifting a weight.
Having said that, there is a difference between lifting a light load in a state of fatigue that "feels" heavy, and a load that “is” heavy. The main difference between the 2 is the heavy load will induce earlier recruitment of the fast twitch fibers and more eccentric microtrauma during the lowering phase of a movement, which is the primary stimulus for growth of muscle protein myofibrills, while the lighter load lifted in a state of fatigue, often associated with more repetitions, will tend to induce more growth through increased “energy and water storage” mechanisms."
Detta är vad jag alltid trott, men folk verkar inte tro på det.
