A 17-day spaceflight resulted in little atrophy and loss of absolute force but increased unloaded shortening velocity in slow and fast gastrocnemius fibers, with significant intersubject variation.
No takes yet. Share an insight, caveat, or question.
Increased fiber shortening velocity post-spaceflight may affect astronaut performance; extends microgravity observations but remains hypothesis-generating without randomized confirmation.
Widrick et al. (2001) studied this question.
