Cycling Cross-Bridges Contribute to Thin Filament Activation in Human Slow-Twitch Fibers
Frontiers in Physiology, 2020 It has been shown that not only calcium but also strong binding myosin heads contribute to thin filament activation in isometrically contracting animal fast-twitch and cardiac muscle preparations. This behavior has not been studied in human muscle fibers

Effect of ADP on slow‐twitch muscle fibres of the rat: implications for muscle fatigue [PDF]
The Journal of Physiology, 2006 Slow‐twitch mechanically skinned fibres from rat soleus muscle were bathed in solutions mimicking the myoplasmic environment but containing different [ADP] (0.1 μm to 1.0 mm). The effect of ADP on sarcoplasmic reticulum (SR) Ca2+‐content was determined from the magnitude of caffeine‐induced force responses, while temporal changes in SR Ca2+‐content ...

The stiffness of slow-twitch muscle lags behind twitch tension: Implications for contractile mechanisms and behavior [PDF]
, 1979 Small, square stretches were applied during contractions of soleus and plantaris muscles in the cat to measure muscle stiffness. The stiffness of the slow-twitch soleus muscle (but not of the fast plantaris muscle) reaches a maximum after the peak in ...

Mitochondrial dynamics define muscle fiber type by modulating cellular metabolic pathways
Cell Reports, 2023 Summary: Skeletal muscle is highly developed after birth, consisting of glycolytic fast-twitch and oxidative slow-twitch fibers; however, the mechanisms of fiber-type-specific differentiation are poorly understood.
