Shorter stockier legs, shorter toes, indicates strength dominance, less tendon elasticity in general... so ST might be a better route (maybe). Longer legs, longer toes may indicate greater tendon elasticity and plyos may benefit you more, or rather, you may respond to plyos better. There are plenty of athletes that only do plyos and become high fliers and can't squat shit. But that doesn't work for us for the most part. Similarly, getting "stronger," and I put that in quotes because muscle strength gained in a squat doesn't transfer over to a running vertical jump for everyone the same way so the "strength" being applied during the jump is questionable, doesn't work for everyone either. You hear a few success stories here and there (Kingfush on this forum but i haven't seen his running vert not sure if it exists or his sprint times but if you want to squat to improve your vert, take at least 2 years and devote yourself to weightlifting. Many here take that route, and I haven't seen a single success story yet except for kingfish. As a newbie on this forum, I want you to synthesize your own ideas, like I did, instead of being sucked into the dominant paradigm.
Getting stronger over the past two years (not being able to squat 225 to being able to double 315lbs for two sets) made me slower, and decreased my running vertical jump. But I didn't sprint or jump at the same time. Currently, i am improving my lunge strength (right now doing 190lbs with each leg with dumbells) while doing plyos so we'll see how that goes.
My best vert has been obtained before I could squat 225 comfortably for reps, and afterwards. So clearly something is going on other than muscle size that helps produce "power."
the only thing i did non-conventional is to do my SVJ drills after my squat routine.
you strength trained without doing the skill work of jumping, then expect the jump to improve..

i do many reps of jump drills in a workout to improve my SVJ and those are done after i turned my muscles on with near-max full squat reps.
i could have a 20-40 total squat reps in the 6-8reps for my volume workouts but still have enough gas in the tank to do 100s+ reps of jump drills doing jump ropes, hurdles, jump squats, 2-hand SVJ dunks..
I didn't jump because I couldn't, I didn't feel like it because the motor pattern took over, as it does for most people here who get into lifting heavy. People become preoccupied with it and for get their original goals, to DUNK, and be an explosive beast, not a fat piece of steroid injected shit who deadlifts 1000 lbs... yet that's what you guys like to post in the beast thread, un-athletic fat powerlifters and olympic lifters, nothing to do with athleticism whatsoever.
not going to happen if you do more jump reps. get a jump rope and rep away.
