I am a big fan of periodized training when it comes to track and field, and sport training in general. I like this patterned training because of your ability to peak your performance when you choose. My program i created is my exam workout routine, and consists of all you mentioned, with the addition of core work.
My workout typically begins as so
Dynamic Warmup (20-30mins)
Workout 30mins (Spring/plyo workout, or mix)
Weights (Usually 30 mins)
Then before bed at night, a 20 minute ab routine, then some foam rolling/and or ice
As for my periodized scheme, I typically aim for 12-15 week cycles
Phase 1 Strength/Conditioning ( like a 5×5 weight plan for a simplified example, my workouts consist of strength plyos, and conditioned sprints (150-400m hill work, 3x5mins tempo run)
Phase 2 Explosive Work (lighter weight, explosive reps in weight room, plyos become more of the focus, sprints shorten, and intensity rises, recovery increases
Phase 3 Technique and Taper, I like to use this week to actually concentrate on the technicalities of running and jumping, while I naturally taper up, weight room becomes really light and explosive, sprints become extremely intense, short, and full recovery between, (Ex 6×30 meters with full recovery between reps)
My style is different than most, but I am very confident with it, and my results thus far. It is great for plateaued or bored athletes as well, sorry for the delay in answering, ive been traveling a bit!
