Interested in research and orthopedics. Just here to learn.

@GregLehman I think it's partly an issue of science communication. The authors probably arent trying to reach people like you, but rather, the many clinicians who might benefit from prescribing more exercise. To make a message stick with the average clinician, sometimes simple is better, no?

@PhysioNetwork Why are the early portions of stance (heel strike to foot flat) used to illustrate the article's argument, given that these phases of gait require minimal dorsiflexion and are rarely limited by insufficient dorsiflexion?? Is it just to illustrate the concept of relative rotation?

[Cameron Swick @CamSwick]

@ProfJillCook @brian__healy @hjluks Hi Dr. Cook, is this related to the reason why elastic bands are suboptimal for tendon loading, as Dr. Luks mentioned? In my mind, if reps are performed slowly, bands shouldn't involve much more energy storage/release than other types of load. I'd love to read some papers on this

@mboyle1959 Looking at your book (section: Learning to Leg Curl). You describe hamstring as "extensors of the hip & stabilizers of the knee." With Nordics, is the aim to train resisted knee flxn w/ large emphasis on maintaining hip/pelvis stability? Which goes beyond simple glute activation?

[Cameron Swick @CamSwick]

@mboyle1959 Not trying to argue--just trying to understand your perspective. Thanks again.

@physiorichmond Agree that it would be helpful if the report had context regarding base rates, incidental findings, etc. However, I think many people would be justifiably irritated if they needed to wait around for a clinician in an already slow healthcare system.

@Ekkekakis Would have wholeheartedly agreed with you 5 years ago. I'm now less certain; perhaps the headline's message is a good fit for our current societal constraints/norms, which are far bigger than exercise science. What alternative messages do you prefer?

@timkettenring @mboyle1959 100% agree re: physiology. It’s always a spectrum, and even sprint repeats are mainly aerobic unless rest periods are long. I’m just wondering what type of activities you were referring to in your original post. Specific examples of workouts wrongly purported to increase VO2 max

[Cameron Swick @CamSwick]

@timkettenring @mboyle1959 Could you give examples of "anaerobic" activities that are erroneously purported to increase VO2 max? E.g., short sprints with full recovery between sprints??? Just trying to understand your perspective, as I agree that interval training is almost never "anaerobic."

@GregLehman (elastic region being the linear portion of the stress-strain curve)

[Cameron Swick @CamSwick]

@GregLehman Quick question on SWE. Friede speculates that the increased ITB stiffness may be d/t greater resting tone of the TFL/GM. Does muscle tone affect SWE-measured stiffness of the tendon or ITB? In my mind, it shouldn't, provided the connective tissue is measured in its elastic region

@PeteOSullivanPT @GregLehman @CraigLiebenson @DrZoffness @MattLowPT @Peter_Stilwell @sconinxphil @jpcaneiro Thank you. Are you saying that, in an adequately powered study that already had a fairly large sample and found large effects/small p-values, further increasing the n would increase generalizability? Even if inclusion/exclusion criteria were kept the same?

[Cameron Swick @CamSwick]

@PeteOSullivanPT @GregLehman @CraigLiebenson @DrZoffness @MattLowPT @Peter_Stilwell @sconinxphil @jpcaneiro Also @PeteOSullivanPT, how does the sample size (not the selection criteria--just sample size) affect your interpretation? Just wider confidence intervals and greater risk of type I error?

[Cameron Swick @CamSwick]

@PeteOSullivanPT @GregLehman @CraigLiebenson @DrZoffness @MattLowPT @Peter_Stilwell @sconinxphil @jpcaneiro Thank you Greg and Peter for the nuance. I agree. It just seems that Van Dillen's paper is rarely brought up in these discussions, but perhaps(???) that's appropriate given that it's a more selective efficacy trial. We'll see what happens with the pragmatic trials.

[Cameron Swick @CamSwick]

@CraigLiebenson @GregLehman @DrZoffness @MattLowPT @PeteOSullivanPT @Peter_Stilwell @sconinxphil @jpcaneiro What are your thoughts on Van Dillen’s 2021 JAMA paper? Its effect size was similar RESTORE’s, it had an active comparator group, and its experimental intervention was almost purely biomechanical (whereas RESTORE’s was multidimensional). Unsure where Van Dillen’s study fits in.

@LaurenTuethDPT @MDHarrisLab @GSSwustl @wustl_pt Thanks Lauren! And also, my project is primarily under the supervision of @MHarrisHayes, although @MDHarrisLab is also a contributor!

[Cameron Swick @CamSwick]

@PT_ATC_CSCS @kcrehabguy @kgSilbernagel @doclsmack @AirelleGiordano @JOSPT That's my interpretation too. To dose NMES, you perform an MVIC beforehand w/out NMES, and then apply NMES without voluntary contraction to see what intensity is needed to elicit 50% MVIC w/out voluntary activation. Use at least this intensity of stim for subsequent exercises.
