The Hypertrophy Component

What is Hypertrophy?

In Hypertrophy, there is increase in the size of the skeletal muscle through the growth of the component cells.

There are two factors in the Hypertrophy

  • Sarcoplasmic Hypertrophy.
  • Myofibrillar Hypertrophy.

Sarcoplasmic Hypertrophy

It mainly focus on increased sized muscles Glycogen storage.

Myofibrillar Hypertrophy

It focuses more on increased Myofibril size.

How to Stimulate Hypertrophy

A stimuli can increase the size of the muscle cells. After there is adaptive response which serves the ability to generate force in anaerobic conditions.

Strength Training

Strength training bring the neural and muscular adaptations. Which increase the capacity of an athlete to exert force through voluntary muscular contraction. After some time, the neuro muscular adaptation dominates. The process of muscular hypertrophy observed while the size of the muscle tissues increased.

Anaerobic Training

The best approach to specifically achieve muscle growth remains controversial (as opposed to focusing on gaining strength, power, or endurance); it was generally considered that consistent anaerobic strength training will produce hypertrophy over the long term, in addition to its effects on muscular strength and endurance. Muscular hypertrophy can be increased through strength training and other short-duration, high-intensity anaerobic exercises. Lower-intensity, longer-duration aerobic exercise generally does not result in very effective tissue hypertrophy; instead, endurance athletes enhance storage of fats and carbohydrates within the muscles, as well as neovascularization.

Temporary Swelling

During a workout, increased blood flow to metabolically active areas causes muscles to temporarily increase in size, also known as being “pumped up” or getting “a pump”. About two hours after a workout and typically for seven to eleven days, muscles swell due to an inflammation response as tissue damage is repaired. Longer-term hypertrophy occurs due to more permanent changes in muscle structure.

Factors Effecting Hypertrophy.

Biological factors (such as genetics and sex), nutrition, and training variables can affect muscle hypertrophy.

During puberty in males, hypertrophy occurs at an increased rate. Natural hypertrophy normally stops at full growth in the late teens. As testosterone is one of the body’s major growth hormones, on average, males find hypertrophy much easier to achieve than females and on average, have about 60% more muscle mass than women. Taking additional testosterone, as in anabolic steroids, will increase results. It is also considered a performance-enhancing drug, the use of which can cause competitors to be suspended or banned from competitions. Testosterone is also a medically regulated substance in most countries, making it illegal to possess without a medical prescription. Anabolic steroid use can cause testicular atrophy, cardiac arrest, and gynecomastia.

A positive energy balance, when more calories are consumed rather than burned, is required for anabolism and therefore muscle hypertrophy. An increased requirement for protein, especially branch chained amino acids, is required for elevated protein synthesis that is seen in athletes training for muscle hypertrophy.

Conclusion

Muscular hypertrophy is a multidimensional process, with numerous factors involved. It involves a complex interaction of satellite cells, the immune system, growth factors, and hormones with the individual muscle fibers of each muscle. Although our goals as fitness professionals and personal trainers motivates us to learn new and more effective ways of training the human body, the basic understanding of how a muscle fiber adapts to an acute and chronic training stimulus is an important educational foundation of our profession
