[quote author="dbandre" date="1222465563"][quote author="Jeremy Richmond" date="1222444243"] I think dbandre knows a lot more than me about resonance because it refers to the behaviour of springs.
I wish I knew more than you about it. Like I said I have been trying to do this for 3-4 years now after starting with a simpler model and trying to apply to weight room numbers and ultimately I have almost given up on trying to come up with a model that will help analyze deficiencies in a race. Instead my weight room workouts evolved to be shorter and less frequent with an emphasis shifting over the course of a season from larger range of motion in squats to smaller ranges of motion in squats. I also went to lighter but faster Olympic Lifts. I also complex my Squats/Deadlifts with an Olympic Lift following the strength lift about 40% of the time. All of these aforementioned items are something most on this board would disagree with. Another thing I do is drop landings and sticking the landing on drops cueing a stiff as possible landing in my plyometric routines.
On the track the my workouts move from more accel/maxV to more speed/special endurance throughout the season, i do have tempo endurance work throughout the season which keeps them fit enough to race the longer sprints while this transition occurs. My horizontal jumpers do this kind of stuff as well. They go from 4-7 stride approaches back to 6-12 strides as the season progresses.
To sum it up my approach is basically a developmental one in which the sprint training throughout the season mimics how acceleration in a race occurs going from less elastic training to more elastic training. Would this training work with and Elite Sprinters??? Maybe, Maybe not, I don’t really know, but it has been effective for myself and an improvement over former training methods and the methods seem to fit my cueing and feedback instruction to athletes better than approaches, but those too have evolved.[/quote]
Why would most on this board disagree with these methods? Larger to smaller range of motion in squats sounds exactly like I would do it. It is extremely specific and one can load up and create a response more akin to that encountered in actual sprinting.
Drop landings and sticking has quite a good efficacy on tendon/connective tissue strengthening. My only concern is that it is too much stress on the body which would explain the need to train less often. In terms of efficacy I was reading a thesis on drop jumping where the researcher proposed a method that had terrific results. I’m not disclosing it here but I wish that researcher would publish it.
For now my understanding of the strengthening of the tendons and connective tissue has little to do with formulaes (causing massive headaches) and more to do with feel. I think we have all seen footage of the Jamaican’s doing a high knee drill on a road (warning- do not try this at home) that was uphill. I think this would create appropriate elastic resonance strength for sprinting.
By the way, the method you disclosed above about 4-7 to 6-12 strides etc. seems to have a similar concept to that in the thesis I mentioned above. Are you willing to give more detail on that method? Fully respect your decision if you want to retain the secrets.[/quote]
No secret about the short approach to long approach for jumpers. It comes down to their ability to accelerate and jump. What good does a full approach or near full approach work do for someone coming into the season? If I had a HS girl who can jump 14-15 feet starting at 4-6 strides they will end the season jumping 16-19 feet on 7-10 strides depending on their developed abilities and level of skill which was developed. Their competitors start on 7-10 strides and stay on those marks throughout the season, but they do not improve as much, regress, or get looked over because they were trained enough and lacked strength/power and/or acceleration(speed) to jump at such marks.
I see the reason as follows:
It lays a good foundation to work on acceleration pattern development progressively as the season progresses.
The starting distance doesn’t allow for speed generated from acceleration to excessive for early season jumps especially in GPP and SPP.
As the season goes along they will get faster and likely need to move back, and once an original mark moves back around 12-15+ inches it’s time to move them back farther and take more strides in the approach. The consistency on the board is enhanced too it seems, sometimes it gets iffy when I change the strides, but it seems to last a day or two. If a jumper cannot equal or better their previous PR’s when they move back you can scratch the idea.
It also creates a fall back as a jumper who might be struggling with fatigue I’ll allow the go back to their previous stride number and mark. It’s rare, but I have had to do this at the HS level especially at dual,tri, and quad type meets.
I also think it teaches mastery and competence to the athlete who then derives greater self-confidence in their performances. They notice themselves getting faster, stronger, and jumping farther, they get the feel of jumping while still accelerating, they hit the board more frequently than a majority of their competitors, their body and brains start to understand the physics involved and they become better able to relate that feedback back to me and it just seems to snowball from there.
As for the 1/4 and 1/2 squats to deep squat argument. There is a thread floating around this forum somewhere where I believe I was the only who advocated moving from parallel(3/4) to 1/4 squats as the season progressed.
