MKM sanoi:En ole lihapyörykkä, mutta vastaan kuitenkin. Pitkillä sarjoilla hankittu lihaskoko on enemmän sarkoplasmaa, voimaa tuottamatonta proteiinihyytelöä lihassolujen välissä. Lyhyemmillä sarjoilla hankittu lihaskoko on enemmän sarkomeerejä, lihassolua kasvattavaa ja voimaa tuottavaa proteiinia. Sarkoplasma katoaa nopeammin kuin sarkomeerit
Simon sanoi:"If you want to get into studies, there are lots of them that show that protien sysnthesis returns to base levels after 36-48 hrs, at most. This is generally accepted in the exercise science community as well."
There are a number of reasons why those studies could be misleading:
Protein synthesis must increase initially to compensate for the increased rate of degradation caused by the workout itself. This could simply be a recovery issue and have nothing to do with the actual growth mechanism. It may be that the growth production process doesn′t truly begin until other systems, such as the peripheral nervous system, have recovered. Have these studies actually looked at protein synthesis 10 days or so after the workout? Have they just assumed that once the initial protein synthesis increase subsides that there is no more to come?
I know that the studies say that protein synthesis happens first, followed by “remodelling” of the myofibrils. It is entirely plausible to suggest that the protein synthesis required to manufacture NEW myofibrils doesn’t start until much later, and that the protein synthesis measured in the studies represented stage one in the repair of the old ones.
If muscle growth does indeed happen relatively soon after the workout, a lengthy recovery period would most likely still be required as any meaningful muscular increase would obviously require strenuous, nervously taxing training. If the price of a significant rate of muscle growth is a lengthy recovery period for the central and peripheral nervous systems, then so be it. In the study I mentioned in my above post, it took the subjects about 10 days to recover FIVE PERCENT of the strength inroad they sustained. Even if elevated protein synthesis were long gone by then, any new muscle gained would in effect have been useless. If they had trained again whilst still week and nervously depleted, the training workload would not have been sufficient to provide a progressive overload. You can only continue to stimulate muscular gains if you demonstrate increased strength every workout.
In my own personal experience, I have gained significant amounts of strength using 1 set every 3-4 weeks (75 pounds on 5RM deadlift in 4 months for example), strength that I’m sure I wouldn’t have gained training with a higher frequency. A typical deadlift workout would result in a 10-20 pound gain in weight lifted. Gaining that amount of strength in the space of two days after a workout before having to rest another three weeks to demonstrate it seems incredibly inefficient. I doubt there has been any study which looks at protein synthesis rates 2-3 weeks after an extremely intense workout. I don’t think your typical exercise scientist would ever dream of such a ridiculous idea! I mean, when you think about it, the kind of progress reported on this forum just shouldn’t be possible according to exercise “science”!
Simon sanoi:Yes, protein synthesis happens very early on, but there is no evidence that this produces real MYOFIBRILAR growth. Using the tape measure is completely unreliable as there is a lot of evidence which points to the phenomenon of "sarcoplasmic hypertrophy": the increase in the glycogen and water content of a muscle fibre, not the protein content. If you do many and frequent sets of weight training, as I know you do, the effect of glycogen depletion is greater. I′m sure your aware that the body responds by supercompensating on glycogen. Now the important point is that one gram of glycogen binds to three grams of water. So more sets equals more glycogen which leads to much more water, which leads to a bigger - though not stronger - muscle fibre. To get stronger, the contractile element of the muscle fibre, the myofibril, must grow; the only way it can do so is through protein synthesis. So, the growth that you witness during your high volume loading periods is, I believe, partly due to increased glycogen and water content in the muscle fibres, rather than a result of protein synthesis. Yes, youfre acutely stimulating protein synthesis every time you lift weights, but what is the actual purpose of this initial increase? It may just represent the early stages of the recovery process, the COMPENSATION for protein broken down during the workout. I am not aware that science has told us that this increase in protein synthesis rates represents OVERCOMPENSATION in the form of an increase in the number of proteins required to form new myofibrils, and thus new growth. My point is that we do not know for sure whether elevated protein synthesis returns several days/weeks after the training stimulus as no one has ever tested for it.
gPut simply, to demonstrate your maximum strength, the nervous system must be completely recovered.h
This is exactly why overtraining, or over-reaching, does not stimulate real, contractile, muscle fibre growth. If you are too weak to even repeat a previous lifting performance, you are merely repeating a feat your body already knows it is capable of. If your body has already adapted to a lighter load, why does it need to do so again? All you achieve by training when nervously depleted is further nervous depletion. Surely the last thing the body is going to be concerned about is engaging in the metabolically expensive process of building new muscle when it has an ever increasing hole of nervous depletion to contend with. Especially when that new muscle wouldnft even have an effect of increasing strength, not for weeks at least! Thatfs not to mention the likely increase in cortisol levels associated with any kind of over-stress or tiredness; and as everyone knows, elevated cortisol levels will kill your muscle building efforts dead.
gIf IŒm eating and training hard enough, when I have an arm workout, my measurement increase by 1/16 to 1/8 of an inch by the next day, and it sticks.h
Building new, raw muscle tissue takes time. I seriously doubt that that increase in arm size OVERNIGHT is as a result of protein synthesis. Whatfs happened is that your muscles have soaked up the carbohydrate youfve eaten after your workout and used it to super compensate their glycogen stores. This glycogen has then drawn in even more water and - bingo - youfve woken up the next day with noticeably bigger muscles. The real business of muscle growth has then taken place later on, when you havenft been in a state of nervous exhaustion.
My main point is that the elevated protein synthesis which immediately follows the training stimulus has been ASSUMED to be muscle hypertrophy; and that there may have been some false training conclusions drawn from those studies that measured it. There is still a lot left for science to prove.
Kyllä voi! Esim selkätreenin alkuun voi hyvin tehdä pulloveria joko koneella tai narulla ylätaljassa. 100 toistoa tietenkin niin että saat polttavan kivun tunteen latseissa! Sen jälkeen onkin helppo saada liikkeet kohdistumaan, sillä verta on jo päässyt virtaamaan lihakseen.ancelita sanoi:Hei hieno vinkki, pitääpi itsekin kokeilla ku *tahtoo* isot olkapäät :D Mihin muihin lihaksiin toi toimii hyvin?? Mitä muita lihaksii oot kokeillu, Bisley?? Mulla ei taho nuo takareidet turvota, toimiskohan niihinki esim. maaten koukistuksilla?
Vane Glide sanoi:Katopas Bisleyn kuvat ja ala sitten vastaan kommentoimaan onko harjoittelussa ollut "mitään järkeä"
onko kellään mitään kuvia tosta takaolkapää koneesta kun ois hieno kokeilla tota Miken sanomaa treeniä mutta kun en tiedä oiken minkä näkösestä vehkeestä on kysymys??
Väsäsin huonolaatuinen animaatio takaolkapäälaitteesta.
