- Muscle hypertrophy refers to the increase in muscle size due to growth in muscle fibres.
- The process involves enlargement of cross-sectional muscle area following strength training demands.
- Structural changes include an increase in actin and myosin filaments within the muscle cells.
- Myofibrils within muscle fibres also enlarge to support enhanced muscle contraction.
- Connective tissues that support muscle contraction strengthen during the hypertrophy process.
- These adaptations occur when muscles are challenged beyond their normal capacity through progressive resistance training.
