Animal findings on fiber-type stretch injury warrant clinical caution; leaves open translation to human muscle or therapeutic targets.
In rat muscle fibers, fast fibers incur greater force deficits than slow fibers following single stretches, although ultrastructural damage is similar for a given force deficit.
Macpherson et al. (1996) studied this question.
