Rabbit muscle adaptations to altered excursion or load should not guide human procedures; leaves open translation of longitudinal growth versus hypertrophy mechanisms.
Experimental alteration of muscle mechanics in young rabbits induces specific hypertrophic adaptations, with increased excursion leading to longitudinal growth and increased load leading to increased girth and tension.
Greg Crawford (1961) studied this question. Tendon transfer or elimination of synergic muscle vs. Control was evaluated on Muscle length, girth, weight, and isometric tetanic tensions. Tendon transfer increased muscle length and tension range, whereas eliminating a synergic muscle increased muscle girth, weight, and isometric tetanic tension compared to controls.
