Stretch-Mediated Hypertrophy Definition

  • Stretch-mediated hypertrophy refers to extra growth from training in stretched positions.
  • This "extra" growth comes from adding sarcomeres in series (sarcomerogenesis), unlike typical hypertrophy from adding myofibrils in parallel.

Fascicle Length Adaptation Timeline

  • Increases in muscle fascicle length occur rapidly, within weeks.
  • These increases plateau much sooner than cross-sectional area increases, which develop more gradually.

Fiber Length vs. Sarcomere Length

  • Muscle fiber length and sarcomere length are distinct concepts.
  • A muscle fiber can be lengthened without experiencing passive tension, crucial for stretch-mediated hypertrophy.
