First day at a new job in the evolutionary #biomechanics lab at @imperialcollegeldn.bsky.social! We're studying how insect legs gear with size and environment on a @leverhulme.ac.uk grant. Our first subject is here already and I'm excited!

New preprint, perfect reading for #SEBconference travel
We simulate how age-related changes to muscle affect point-to-point movement.
Reductions in force, velocity and activation independently reduce performance, but deactivation and stiffness interact!

A well-overdue study to evaluate an equation used by ~everyone in fossil trackway studies (including me). Good job to @peterfalkingham.com and team!
New paper led by Tash Prescott - we applied equations for speed, etc that are commonly used on #dinosaur tracks to tracks made by living birds we could watch and time. TLDR: equations aren't even nearly close. Animals moving freely on compliant substrates very different to steady-state lab data
Speed from fossil trackways: calculations not validated by extant birds on compliant substrates | Biology Letters
Fossil trackways serve as a valuable tool in understanding the behaviour and locomotion
of extinct animals. Calculating speeds from trackways has become a standard approach,
particularly for dinosaurs...

The results are in, and a staggering 82% voted for (a), the lower mechanical advantage jumping higher.
The correct answer is actually (b), and I think this problem highlights how unintuitive gearing can be in #biomechanics
A short thread [1/9]

Fun problem: 2 mammals are identical except for limb extensors mechanical advantage (G)
Which jumps higher above standing?
Muscles have same force length properties. Ignore force velocity properties. Vertical forces only, external force is gravity
