The static dynamic method applied literally is more for weighted lifts: For example, before a maximum bench press unrack a 120% 1rm load and hold it at lockout for a few seconds. Before a maximum hang clean or snatch take a heavy weight and do a set of shrugs. I always had my best snatch and cleans doing that by a wide margin, but it doesn't work for everyone. It'll work for squats too but you gotta be careful because the weight on the full range set will feel extremely light and there's a natural tendency to lose tightness.
For dynamic bodyweight movements I'd use isolation exercises with relatively light weight for very short periods just to get certain muscle groups fired up better. For sprints something like lightly loaded reverse hyper hold for 7-10 seconds or iso extension iso hold followed by a set of short sprints a few minutes later. Same for bodweight hip flexor holds.
I got my hang clean up 45 lbs doing something very similar in college, I used a high pull from the hang with 50lbs of chains added, (have to hang the chains attached to collar so there is loading/deload throughout the whole rom and not by small chains). I would do a set of 3 with the chains, rest 2 minutes, then take the chains off and hit pr after pr for a good period of time. Ive noticed that this potentiation method works extremely well with more dynamic lifts, where the body has a limited amount of time to produce force. Jump squats with band tension, then removing the band and repeating the set almost always gives a pr for everyone on the the tendo for height and speed.
