Thanks! Yes, definitely worth assessing and integrating as the calf (esp gastroc) plays an important role in absorbing the force during a COD. I have more coming up on this channel about COD and decels in the near future!
Could the soleus's role in vertical GRF be dependent upon subject population?? I feel as though strength-power athletes would utilize more knee extensor musculature rather than plantar flexors, while endurance/mixed athletes could use more plantar flexors than knee extensors.
Hi. It's an interesting question. There will of course be individual variation and training history could potentially be a factor. Both the Dorn and Hamner and Delp studies used "experienced runners" as subjects. I suspect that while the magnitude might change, the trends of vGRF and muscle contribution across different running speeds would be similar.
@@globalperformanceinsights Thank you for your response! It would certainly be interesting to see the differences in American football, especially in some of the faster WR's reaching around 9.5-7 m/s
Hi Nicolas. Thanks for your question. I presume that is because you find athletes of that height don't fit? I'd say there's a few different ways to build a rig, often using a squat rack, straps, or you can have a custom built rack made (if you have the budget for it!).

Brilliant. Keep these videos coming!
Thank you Dr Goodin!
Brilliant
Thank you!
"This video is pure gold! Thanks for sharing."
My pleasure!
Thank you, great video! Made my thesis testing way easier
Great to hear!
Perfect work 👋👋👌 What do you think about testing calfs/ankles in context of deceleration in sport (horizontal dec, COD etc.) ???

Perfect. Cant wait. 🙏🙏

Hello
Very good video, but I have a practical question regarding the Sitting Calf Raise Test. How can it be applied to players taller than 190 cm?
