The exercises you listed are variations, but they do indeed target specific power fibers.
Explosiveness = power.
Strength is the ability to generate force within a single contraction.
Power is work per unit of time. (Speed strength).
I would like to see some bodybuilders or anyone in general that has a good amount of hypertrophy using 3-5 reps as his typical rep range. Drug talks aside of course.
Drugs have nothing to do with what rep range would work for someone. Anabolics increase your bodies ability to produce artificially enhanced testosterone, more efficient than regular testosterone at building muscle, and you have unlimited amounts - meaning you cannot overtrain your endocrine system. Drugs won't change what occurs with high or low reps.
I mean i'd love to train with 3-5 reps, its just its never worked for me in the past even with my nutrition/supps being on point, and it always resulted in some kind of tendonitis of some sort, and have yet seen any great physiques built on 3-5 reps as their typical rep range. Though correct me if im wrong, Christian T over at Tnation typically uses low reps for his hypertrophy training? Even though myofibrillar hypertrophy has been shown to be best around 3-5 reps, reality has shown for most people it just gives them injuries and more so strength gains via strengthening CNS/connective tissue. My point is just I want to get inspired via seeing others develop muscular physique using low reps for hypertrophy, just really haven't seen it yet...
Those are all examples of athletes / coaches that have had hundreds of clients gain LBM and specific hypertrophy with low reps.
As long as contraction and recovery both occur, hypertrophy can result.
Low reps do not cause injuries. Injuries are mainly caused by form issues. If someone is lifting with their ego and not their intelligence, then they will get injured and it doesn't matter if it's high or low reps.
Look at lightweight powerlifters as an example of hypertrophy development in response to low reps.
