oscid, если прочитаешь я поддерживал что сила F=ma одна, а то, что для мышцы есть разница 100х1 за 4 секунды или 50х1 за 2 секунды несмотря на это. Механический натяг от 100кг выше. Недостаточно вдвое меньший вес поднимать вдвое быстрей для паритета.
If we lift a light load with a maximal effort (in unfatigued conditions), the weight moves very quickly. During this lift, our motor unit recruitment levels are very high, and therefore most of the muscle fibers are active.
However, despite the high levels of motor unit recruitment, overall muscle force is not particularly high, because each muscle fiber only exerts a small amount of force when it shortens quickly. This is why we produce much lower forces during maximal effort vertical jumps compared to in one-repetition maximum back squats.
Напротив, Бирдсли говорит, что намеренно медленные повторы достигают большего механического натяга на отдельные волокна, чем быстрые повторы.
As you can see, the mechanical tension experienced by whole muscles is very different from the mechanical tension experienced by each muscle fiber. Muscle force (and therefore mechanical tension) decreases from the fast lift with a light load to the deliberately slow lift with a light load, but individual muscle fiber force (and therefore mechanical tension) increases substantially from the fast lift to the deliberately slow lift.
