is it possible to compare an experimental isokinetic testing with varying the velocity for leg flexion and extension (leg press) with the AnyBody simulation? I think by varying the velocity there is a difference in the muscle recruitment pattern for the M. quadriceps, but it seems to have a biological theoretical background. Can AnyBody produce changing in the muscle recruitment pattern by changing the speed of movement? Thank you. It´s the first time I post some Question and I´m nervous if you will understand.
Hello Heike,
I can think of the following cases where varying velocity will cause a difference
-
If there are velocity-dependent forces in the system, such as centrifugal forces, gyroscopic forces or Coriolis forces.
-
If the larger velocity also leads to larger accelerations (which it often will).
-
If you use the three-element Hill muscle model, which includes contraction dynamics. In this case, the faster the muscles contract, the weaker they will be.
I hope that helps.
Best regards,
John
