![]() ![]() Hypertrophy refers to the increase in size and strength of muscles through targeted exercise, specifically resistance training. It is often sought after by bodybuilders who aim to achieve a more aesthetically pleasing appearance.įigure 1: Normal muscle cell, Myofibrillar hypotrophic cell and sarcoplasmic hypertrophic cell. Sarcoplasmic hypertrophy results in an increase in muscle size and volume but may not significantly improve muscle strength. This type of hypertrophy is associated with high-volume training, typically with moderate weights and higher repetitions. Sarcoplasmic Hypertrophy: Sarcoplasmic hypertrophy involves an increase in the amount of sarcoplasm, the non-contractile fluid, and energy stored within muscle fibers.Understanding the principles of hypertrophy and their application to resistance training allows individuals to strategically manipulate training variables such as volume, intensity, and exercise selection to optimize muscle growth and strength gains. It leads to an increase in muscle strength and is often pursued by athletes and powerlifters. Myofibrillar hypertrophy is associated with heavy weight lifting or resistance training with high loads and low repetitions. ![]() ![]() Myofibrils are the contractile components of muscle cells that contribute to muscular strength. Myofibrillar Hypertrophy: This type of hypertrophy is characterized by an increase in the size and number of myofibrils within muscle fibers.There are primarily two types of muscular hypertrophy (Roberts et al., 2020) : ![]()
