Sarcoplasm

The fluid and non-contractile components within muscle fibers.

Sarcoplasm is the cytoplasm of muscle fibers, containing glycogen, enzymes, mitochondria, and other components. Sarcoplasmic hypertrophy increases these non-contractile elements, increasing muscle size without proportional strength gains. This type of hypertrophy is emphasized by higher rep, metabolically demanding training.

Examples

  • Fluid component of muscle cells
  • Stores glycogen for energy
  • Increased with high-rep training
