Article Synopsis
- The study examined how isometric contractions at short muscle lengths affect the slack length of relaxed skeletal muscle, specifically the vastus lateralis, using ultrasound imaging.
- Findings showed that voluntary contractions reduce muscle slack length by an average of 10°, regardless of contraction intensity, with the most significant effect occurring 5 seconds post-contraction and gradually decreasing over time.
- A subsequent slow stretch of the relaxed muscle can increase slack length, counteracting the effects of the preceding contraction, with larger stretches (over 30°) proving more effective in diminishing the contraction's impact.
