Немного шоковая (для меня) статья о негативах. Оказывачка более быстрый опускания прибавляют больше силы и гипертрофии, чем более медленные просто потому, что используются бОльшие веса. Главное хоть как-то контролировать вес при опускании.

Basically, if you want to lift quickly (concentrically), you must use a light weight. If you want to lift a heavy weight (concentrically), you must move slowly. If you want to lower a heavy weight (eccentrically), you must move quickly. If you want to lower slowly (eccentrically), you must only use a light weight.
Even though lowering slowly is a good idea when combined with a concentric phase, it is not the best way to get stronger in the context of eccentric-only training.
When using eccentric-only training, lowering slowly is less effective for gaining strength, because you force yourself to use lighter weights, simply so that you can lower them more slowly. If you lowered more quickly, you could use a much heavier weight (just don’t use a weight that is so heavy you can’t control it, and end up dropping it).
And even though the jury is out when it comes to lighter loads and hypertrophy (Schoenfeld et al. 2015), I think we can all agree that using heavier loads will almost always make you stronger, probably because they provide greater mechanical loading (Schoenfeld, 2010), and I would bet that this applies even when you are just doing eccentric-only training.
Since Farthing & Chilibeck (2003a) also observed greater gains in muscle thickness (measured by ultrasound), they ascribed these greater gains in strength to larger amounts of hypertrophy caused by the higher mechanical loading. These findings are in line with those reported by Paddon-Jones et al. (2001), who found larger gains in type II fiber proportion after fast eccentric training, compared to slow eccentric training.
Later, Shepstone et al. (2005) confirmed these findings, as they found greater gains in strength (at both testing speeds) and muscle fiber size in a fast group, compared to a slow group. In addition, they reported greater muscle fiber damage or remodelling in the fast group.
Еще раз замечу, что это не просто искусственно быстрое опускание веса, который вполне можешь опускать медленно, а именно использование тяжелых весов, которые медленно опускать не можешь.
Так что теперь не буду ограничивать веса скоростью опускания 3-4 сек. и буду постепенно наращивать веса в негативах (они у меня пока раз в две недели вместе с позитивными 5ПМ), но и быстрее чем 1 сек опускать не буду.
