“Try to be more like a super ball not a tomato”
Jim Radcliffe’s advice on plyometric training rang true as he went through a series of progressions for plyometrics. I haven’t read his book on the subject, but watching him to do it and progress, it certainly made sense.
Jumping in place
Radcliffe looked at starting from the basics and working on the correct mechanics from the start. The key is to work on vertical displacement of the hip. He used these cues to help:
- Thumbs up with 2 hands- links to sprinting
- Toes up: ankles locked and loaded
- Head to ceiling: just do it and land quietly.
- Land ready to take off again.
Once the players can do this he uses multiple responses with a pause, so 3 jumps with 2 seconds rest in between. Landing ready to go again. Then do 4-6 in a row.
Then squat jumps with hands behind the head, with a pause, and bending the knees to get more of a shin angle. Repeating these in a pogo fashion with the thumbs up again.
Rocket jump- reach up and down, could reach side to side too.
Tuck jumps-like slide kicks in sprint drills where the heel strikes the butt like sliding up a wall. Or knee tuck with heels in front of the body, hands by chest, knees to hands. Then multiple responses with hands moving up and down.
Spatial jumps- use split jumps, then split jumps switching legs.
Depth jumps- makes sure you land in position correctly. Use “shock” to react and spring back up by not looking at the landing.
We then looked at linear progressions of bounding with horizontal displacement of the hips.
Prance: both feet land and take off at the same time: not skipping. You should hear 1 sound at a time (note to coaches who have music blasting out: you are eliminating one of your key senses).
Gallop: 1 foot forward, keeping the front foot under the body though.
Skipping: extended skips forward with a step high, projecting the hips forward.
Bounding: 1 leg to the other like a prancing activity “Load and fire”, “Load and fire”.
Bounding with more knees drive, working on distance. Bounding with zig zags concentrate on landing.
Hopping: more like top speed work. Over small hurdles “cycling the legs” landing with a pause, then multiple responses. Multiple double leg hops, then with single legs. Then start from a sprinters position and do diagonal hops, again cycling the legs.
These drills are getting quite advanced now. He then worked up to what he did on the 2nd year of training with the guys. Posture is the determining factor for progression. Can you do a single leg squat with the rear knee touching the floor? if not, then "err on the side of doing too little."
Hopping over obstacles and immediately changing direction on one foot, with gradually more acute angles of turning was the start place. When landing, make sure you don't then do a split step to move. Just push from the hips
As if the above plyometric drills weren’t going to help your agility! We then looked at some on the field type work.
- Turn and Run Mechanics (simple)
- Speed cuts: moving off the inside foot, like a pivot action. (Temporal)
- Power cuts: moving off the outside foot. “Sit , dip and drive.” (Temporal)
- Reactionary movement skills.(spatial)
- Games and skills drills (open)
Much discussion took place on the “false step” what is known in the USA as a “plio step”. Radcliffe and Gambetta were quite vehement in coaching this out of players who are doing it. Instead, work on the plant foot under the hip, then power the hips away. Not plant the foot outside of the body and push. The idea was to eliminate lots of foot movements that may look fancy, but don’t actually get you moving anywhere.
(All the time Radcliffe was demonstrating drills he talked about hips, but it was actually his head that lead every action he was doing. That is something I learnt from Steve Morris and I incorporate into the agility work I do with every athlete).
The Sway Drill
A sort of trademark feature from Radcliffe is his Oregon Sway drill (bits can be seen on this video clip here) and it is a great idea for lateral agility. Using 2 small cones or plastic cups, the athlete works on a series of movements that start small and then work up bigger. It requires the ability to squat properly, and to turn, pivot, sway and push hips laterally.
Next up was working on lateral starts, using a cross over step, or the same side leg, but opening up the hips. Then backward turns. Radcliffe also recommended working in sandpit sometimes to create an external load and level of difficulty.
Great presentations and demonstrations, not enough opportunity to do the drills. Space was limited. I like “having a go” and feeling it. Radcliffe is superb, but there was not enough opportunity on the conference to open things up for discussion: like the “false step” or “hip projection”. I have revisited what I do, and taken away the sway drill and Gambetta’s foot dot drill as simple closed drills that athletes can do away from me with easy progressions.
Sport requires speed and power, the training should reflect that. It is easy to get caught on what you can do on a platform or lying down on a bench.
