replies: text: Nice edit(s) and I agree with your comment, they are pretty nice machines at my gym and they have adjustable inclines.  In fact I thought changing the incline was one of the advantages... it's more like walking at low inclines, more like running at higher inclines.  At least that's what the trainer said!  --W.marsh 04:55, 10 November 2005 (UTC)

text: I'm college educated in mechanical engineering and I agree with the above anonymous critic. The fact is that an elliptical's arm and leg motions produce low level accelerations and decelerations, which are physiologically comparable to impacts. Cyclical changes in the velocity vectors of motions must produce cyclical loading of bones. An impact is a dynamic load and an elliptical's loading on the skeleton is also dynamic. However, its loading is not as great, nor occuring as briefly, nor generally as high in frequency as in running on a treadmill. Currently though there is no reason to presume that an elliptical can produce no benefits for bone health. So I have snipped out the conjecture and saved it here until someone can cite a study with evidence to support it: "...the smoother movements do not help to improve bone density (loss of calcium)."--Zymatik 21:30, 1 December 2006 (UTC)
replies: text: As a kinesiologist I feel the need to both support Zymatik's position and provide important corrections. Your statement that "low level accelerations and decelerations are physiologically comparable to impacts" is false. Impulse is only one factor here. A low force applied for a long duration is NOT *physiologically* equivalent to a strong force for a short duration. Notably, different receptors are stimulated, both because of the high impact (peak force) and because of the vibration. I also hypothesize that muscular co-contraction may occur, specifically in response to high impacts. With that said, bone density is positively affected by both muscular tension and moderate impacts. While it may be argued that elliptical trainers offer less stimulation for bone density than treadmills (citation required), it is certain that elliptical trainers offer more stimulation than doing nothing, and do help to *preserve* bone density. However, the removed sentence mentions that it does not *improve* bone density. At the time of writing, I am not aware if this has been proven or not. I support the removal of the unsourced sentence.

message: I'd be curious to see how is exercise on an elliptical trainer transferred to running. IIRC, transfer from cycling to running is fairly low, 60% perhaps. I'd guess that transfer is somewhat higher in this case. GregorB (talk) 21:53, 16 November 2010 (UTC)
