If time under tension is the main driver of muscle growth, then can we just have a completely static exercise routine, for example, just taking a pair of 15 lb dumbells, holding them in each hand with a bent arm, and just holding that position for like 10 minutes? This way we can progress forever with just a basic set of dumbells just by adding more time, and never suffer any injuries (have different positions for different muscles but basically the same idea, just hold a mid-squat position or a bent over hinge position with light weight, etc.
>>77488631It wouldn't cover the full range of motion
>>77488633What if you do a single curl that takes 10 minutes?
>>77488635It would be less time effective than simply doing a heavier weight with higher reps in 2-3 minutes. To last 15 minutes, the weight would need to be considerably lighter. So you would be trading one bottleneck for a different one.
>>77488635Well, first of all, the main driver of hypetrophy is mechanical tension, not TUT. Secondly, the muscle fibres you want to recruit for size respond to force production which requires you to accelerate weight. The optimal way would be to choose a weight that is so heavy that you can not move it quickly but you move it with maximum voluntary intent to accelerate, and then on the eccentric you can control it slowly to extend TUT and get the benefits of that.
>>77488631This is the basis of yielding isometrics and also was a core component of greek, Persian, ancient jeet and east Asian conditioning regimen. As well as the principle behind paused lifts.It was only a component because moving a weight through your muscles full ROM induced more mechanical stimulus than simply holding. You get more growth by doing movements. My traps and upper back in general responded well to strongman style carry training, because I'd have isometric load of holding the sandbag or husafell or yoke or whatever, but there would be little micro movements as I carried it through space. There's something about movement that muscles like.
>>77488650>Secondly, the muscle fibres you want to recruit for size respond to force production which requires you to accelerate weight.Wrong, it doesn't require that.
>>77488703Not in the sense of "explosiveness", but controlled speed is not the same as intentionally slow execution, I specfically referred to intent to acelerate in the following sentence.
>>77488712WRONG.
>>77488712Also, I was referring to type 2 fibres, they don't fire much during low-force movements. In extremely slow movements, isometrics or low-force movements, you are mostly recruiting type 1 which do not change much in size.
>>77488719Why don't you just google it instead of embarrassing yourself?
>>77488631>If time under tension is the main driver of muscle growthIt isn't and even if it was it would take increasing amounts of time or weight to create the same stimulus because failure proximity is where tension peaks on the largest number of (type2) fibers and what makes the mechanosensor cells actually emit mtor that starts the whole hypertrophy thing. Slow reps is very viable isometrics not so much.I have to do a bit more research but it probably has something to do with which metabolic process is failing first. Since there's like 3 or 4 potential pathways that can fail and result in a muscle failing when it's not supposed to.
>>77488722WRONG!!!!!!!!!!!!!!!!!!!!!!!!
>>77488631you fucking faggots will do anything except lift a heavy fucking weight
>>77488712>>77488721>>77488787Lot of words but empirical evidence such as people with that one disease that makes them contract their muscles unwillingly constantly day & night and who end up jacked as fuck without any other physical activity says otherwise. Nice try though.
>>77488982brb tetanusmaxxing for the gains
>>77488631>time under tension is the main driver of muscle growthNo and nothing suggests that's even remotely true. Endurance training has the longest time under tension and the primary adaptation to endurance training is for the muscles to get smaller (and more vascular). Mechanical tension is the main driver of growth because you can't curl a soup can until you get 18" arms.
