Sarcoplasmic hypertrophy is a term used in bodybuilding to describe an increase in muscle size due to increased sarcoplasmic fluid volume. The spelling of the word can be explained using the International Phonetic Alphabet (IPA). "Sar-koh-plaz-mik" is pronounced as /sɑːkəʊˈplæz mɪk/, and "hy-per-truh-fee" is pronounced as /haɪˈpɜːtrəfi/. The word's spelling may be difficult to remember, but it has become commonplace in the fitness industry due to its significance in muscle growth.
Sarcoplasmic hypertrophy refers to a type of muscle growth characterized by an increase in the volume of sarcoplasm, the fluid-like substance found within muscle fibers. It is a process that occurs in response to specific training methods and typically results in muscle size gains without a significant increase in muscle strength.
During sarcoplasmic hypertrophy, high-volume training methods, such as multiple sets with lighter weights and higher repetitions, are employed to induce muscle fatigue and cellular stress. This type of training stimulates the muscle fibers to store more glycogen, absorb more water, and accumulate additional non-contractile components within the sarcoplasm. Consequently, the overall size of the muscle fibers increases, giving rise to the appearance of larger, bulging muscles.
While sarcoplasmic hypertrophy does contribute to muscle size and can enhance muscle endurance, it has limited impact on muscle strength and power. This is because the increased volume of sarcoplasm and non-contractile components does not directly contribute to improved force production by the muscle fibers.
It is worth noting that sarcoplasmic hypertrophy differs from myofibrillar hypertrophy, another form of muscle growth that primarily involves an increase in the number and size of myofibrils, the contractile units within muscle fibers. Myofibrillar hypertrophy is associated with improvements in muscle strength and is frequently targeted through high-intensity, low-volume training methods, such as heavy weightlifting.
The word "sarcoplasmic hypertrophy" is derived from two main terms: "sarcoplasm" and "hypertrophy".
1. Sarcoplasm:
- "Sarcoplasm" combines the Greek word "sarx" meaning "flesh" or "muscle" and "plasma" meaning "formed substance".
- "Sarx" gave rise to the Latin word "sarcoma", which refers to a malignant tumor derived from connective tissues, including muscle tissue.
- "Plasma" refers to the liquid portion of the cell, excluding the nucleus.
2. Hypertrophy:
- "Hypertrophy" comes from the Greek roots "hyper" meaning "excessive" or "over", and "trophia" meaning "nourishment" or "growth".
- "Hyper" is a common prefix used to indicate excess or over.
