The Effects of Acute Passive Stretch on Muscle Protein Synthesis in Humans

We examined the effect of an isolated bout of maximal tolerated passive stretch on fractional muscle protein synthetic rate in human soleus muscle. Eight healthy males performed two separate trials with the same leg; one session of passive stretch and one of intermittent active isometric contraction...

Description
Summary:We examined the effect of an isolated bout of maximal tolerated passive stretch on fractional muscle protein synthetic rate in human soleus muscle. Eight healthy males performed two separate trials with the same leg; one session of passive stretch and one of intermittent active isometric contraction at a force equivalent to that which occurred during the passive stretch trial. This force was ∼40% of maximum voluntary contraction force and produced volitional fatigue in ∼27 min. Intermittent passive stretch, for the same duration, elicited a 6.1° increase in joint angle (P
