🚀 New pre‑print!
QR & SR exp. are used to estimate muscle properties — but assuming that muscle fibres don't shorten during QR is wrong. It leads to:
↓ Underestimated tendon stiffness (~35%)
↑ Overestimated activation speed (~20%)
🛠️ Our method accounts for fibre shortening for better estimates

Accuracy of experimentally estimated muscle properties: Evaluation and improvement using a newly developed toolbox
The mechanical behaviour of a muscle-tendon complex depends on properties such as the force-length relationships, the force-velocity relationship, and the excitation dynamics. Quick-release and step-r...

🔑 Our work reveals that maximal average mechanical power is achieved when muscles spend roughly six times more time shortening than lengthening—a 6:1 ratio that stayed remarkably consistent across more than 2000 tested conditions.

Maximising average mechanical power output during stretch-shortening cycles of rat medial gastrocnemius muscle
The average mechanical power output (AMPO) during a stretch-shortening cycle produced by a muscle depends on muscle length and stimulation over time. While the effects of cycle frequency and muscle le...

Just arrived in Helsinki for the CNB Congress after my bikepacking trip. 🇵🇱🇱🇹🇱🇻🇪🇪🇫🇮 Only ~25km left to the conference site. Curious about the adventure? Read more here.
