Bands are far from being "superior" to free weights, if you said bands + free weight is superior to free weight only resistance, you would have a case to argue. Using a band only set up you have virtually NOTHING at the bottom of the lift.
Agreed. I don't think anyone is arguing against this.
The accommodating resistance effect is nice, but the eccentric overload (bands pulling down actively faster than gravity) is where bands provide something free weight or even chains cant.
Hadn't realized this. I kind of want to try it out now. But of course, you can increase eccentric overload by dropping down faster than is comfortable, or faster than your body can handle in order to lift the weight as powerfully as possible.
E.g. strength or resistance trained folk will take more time to load the jump during the eccentric than someone on a plyo program or even better on a program with these bands. FOrcing them to jump as fast as possible will load their eccentric phase more..right?
The thing with a jump and comparing it to accommodating resistance is, the body is getting LIGHTER, and youre having to move FASTER the higher in the range of motion you go. Youre only applying maximal strength at a very small portion in the bottom of the range of motion. The bands have the opposite effect on the concentric portion, they apply little to no resistance at the bottom portion, then gain tension rapidly as the weight moves towards the top. During the eccentric portion though, they "trick" the cns into preparing for a load it really wont have to deal with in the stretch position, and you will typically get a more explosive contraction due to that effect. That is why many have seen the phenomena of a free weight + bands (even though its MORE resistance) move faster on the tendo than that same free weight without the bands.
On the "tendo?" I'm thinking you meant amortization
This is all probably correct, but in the context of a full training program, you hopefully wouldn't screw up your motor patterns too much, and that was my concern. Neural mechanisms can screw you up, or take you to new heights.
Also, you can still apply maximum POWER at the bottom of the ROM.. just try to jump as high as you can..done. DOens't matter what the resistance is. Even if bodyweight. I feel like you'd get a different stimulus in different parts of the ROM. For example
Bottom of Jump: more power due to greater eccentric loading (or whatever the proper term is?) and amortization velocity.
Top of jump - produce more power and more force, not as much velocity - because the bands apply more resistance at the top, ESPECIALLY in conjunction with weights.
Concern would be RFD/neural mechanisms, could these bands, without appropriate stimuli from other exercises, teach you to jump with LESS speed?Thta's really my question, I should have stated it in the first post.
The reverse band set up has its uses as well, but any time you take away eccentric tension, you better make damn sure youre getting it somewhere else if jumping or anything power related that involves the ssc is your goal.
Right. But who said we're taking away eccentric tension? What about dropping into the squat faster to increase eccentric velocity as I mentioned above.
Bands used as accommodating resistance allow the strength curve to follow closer to the actual strength curve of the lifter... lighter resistance at the bottom of the lift, and gradually increasing to accommodate the strength curve.
DId you mean weaker instead of lighter? THen that makes sense, most people are weaker at the bottom than at the top. What about isokinetic training then
do bands mimic isokinetic conditions? It's probbably like asking if Obama is a fascist, there are similarities but stark differences... Just reading this article briefly, isotonic trainig generally results in LESS increase in jump power compared to isokinetic. I.e. regular weight training results in less increase in jum ppower compared to constant velocity training

Bands also reduce the decelerating affect that dead weight has. If you squat fast you have to slow down or the weight flies off your shoulders. With bands the increased resistance at the top of the lift allows you to accelerate better even to the end of the lift.
THat's why in the controversial thread "the right and wrong way to squat" I recommended always jumping with the squat to prevent it from decelerating. It's definitely more tiring and on lighter days I'll simply rise on my toes and let the bar rise a little bit above my traps.
@Avishek I'd be interested to see your results of over-speed training with the bands to produce faster contraction speeds.
I don't have this exact band yet, but it would be a lot of fun to try this. I've seen one defranco vid doing this, but I had already thoght of it because it made sense. Again, all gains would be neural. If the force isn't there, what does it matter? I think the future in sprint training/jump trianing lies in RFD. So all neural mechanisms such as this could be highly valuable to elite and already very well stength trained athletes.
WOAH - just thought of something. What if I attached the part that goes on your feet, to the top of a squat rack, and sqatting with like an extra 50 lbs? Or just tried jumping, it would greatly reduce ground contact.... it's only 43 bucks on amazon. I'll get it by the end of the month.
