Guest guest Posted December 17, 2005 Report Share Posted December 17, 2005 Dear Colleagues, My name is Iglesias. I´m an ATC from Spain working in a High school and physical therapy clinic in New York. In addition, I work as a sport specific and conditioning coach in a fitness club. I´ve tried to find research papers about the difference between elastic band and free weights in weight training. Pros and cons of both ways of training.

Guest guest Posted December 19, 2005 Report Share Posted December 19, 2005 Hmmm, considering Newton's 2nd law of motion and through personal experience, I'm going to disagree with the 2 shortcomings of free weights and say that when you lift the bar explosively, there isn't a long deceleration time, but a sudden deceleration done in a short time (I hope that makes sense), also, as force is equal to mass x acceleration, as you accelerate and decelerate the weight with free weights, the force changes so the load changes. The mass always stays the same, but the weight (or load) changes. However, attaching bands to the bar the way shown in that article for exercises such as the squat and bench press is a very effective (and difficult) exercise. I'd definitely recommend trying that (when people tell you to try something new with a light weight to learn the technique, this is definately one of those things).

Guest guest Posted December 20, 2005 Report Share Posted December 20, 2005 Benoit, Any information will be useful. Do you think that your athletes can keep their strength and muscle mass using elastic bands instead of using free weights? I´d like to hear any coments.

Guest guest Posted December 20, 2005 Report Share Posted December 20, 2005 Do you think you could give me a better explanation of what this article says to do with the bands and weights? Every time I click on the link, it tells me I have an error, and I've tried numerous times. Thanks What does it say are the shortcomings of free weights, what do they suggest otherwise? At our Y they have Group Power which is using a barbell, but I personally get bored, it's always the exact same exercises to the same music in the same order. To me, that just raises the risk of injury, but maybe it doesn't b/c why would the be promoting something that increases the risk of injury?

Guest guest Posted December 21, 2005 Report Share Posted December 21, 2005 Thanks. My guess is that the reason they are " pushing " this Group Power class is 1) it's really a no-brainer for the instructor, they are told which exercises to do, when to do them, and given their music. The instructors don't have to use their minds at all. 2) I wouldn't be at all surprised if another reason had to do with money. I bet they are paying for this group Power stuff and want to get their money's worth. They used to have a body sculpt class, which I really really like. It was never the same exercise twice. Oh, you are using the same muscles, but always in a different way. Then they started a group Power class at the same time. Now, they've " combined " the two, only it's not in the room w/ mirrors but in the gym. To me, the mirrors should be there to watch your form b/c if you do something incorrectly, you can really hurt yourself. But I got lots of excuses why it needs to be in the gym. " We don't have any instructors " only the instructor they had they told they didn't need her. " We have such high numbers in the class " only there weren't that many, and most of them were the original body sculpt people. " We don't have the room " only the room where the body sculpt class was held didn't have anything in it. No, the real reason was b/c the instructor taught a class prior to this one in the gym and it's just easier for her to stay in the same room. They do a lot of exercises on the stability ball, but I feel you really need a mirror to be sure you're at the right height. I've seen way too many people sitting on balls that were too large or too small for them. I've even gone around and told people " that ball's too small for you " I'm going to have to look up definitive info about what can happen if you use the wrong size ball, maybe we can get a mirror at least in the closet. It's just (to me) a real shame. You sort-of expect these people to be looking out for your welfare, but the more I get involved, the more I don't think they are. There is one instructor who I feel is really, really good. She knows her stuff and I feel she looks out for people. So, I'll just work on my own as much as I can.

Guest guest Posted December 21, 2005 Report Share Posted December 21, 2005 I haven't been following this thread too closely, but I seem to remember references in the past to a study by Corey Andeson involving Cornell basketball, wrestling and football players in which it was concluded that the group that used a combination of bands and weights significantly increased squat, bench press and average power output over the group using just free weights alone when both groups used the same workouts over a 7 week period. I believe all of the participants had between 2 to 6 years of prior weight training. Jon Haddan Irvine, CA --- ClubbellTrainer@... wrote: > > > In a message dated 12/21/2005 4:23:16 A.M.

Guest guest Posted December 22, 2005 Report Share Posted December 22, 2005 , If I'm understanding you correctly, your main concern is whether elastic resistance is an appropriate substitute for free-weight training. I feel that there are some problems with using elastic tension as the only source of resistance. First, unless you are using very heavy bands (JumpStretch etc.), it is hard to get enough resistance for an advanced trainee. Second, how do you assign load? With free weights you can assign load based on % 1RM, but how do you know how much resistance you're getting with bands alone? It's possible, but much more difficult. Finally, elastic resistance is really only appropriate for certain exercises. Exercises where the most difficult portion of the lift is at the beginning of the movement will work fine. Exercises where the sticking point is nearer the top of the movement will be problematic because there is very little tension in the bands at the start of the movement and a lot of tension at the end. In this situation much of the movement will be under-loaded. Cheers, Colin Lewry Regina, Saskatchewan Quote Link to comment Share on other sites More sharing options...
