On the other hand, real muscle growth is caused by myofibrillar hypertrophy, which happens when you train with heavy weights for low reps, and this type of hypertrophy is also responsible for huge strength gains.

It primarily induces myofibrillar hypertrophy which is responsible for visible increases in muscle mass.

Most martial artists and non-heavy weight lifters will choose myofibrillar hypertrophy, since their goal is having strong muscles but keeping their weight down, while bodybuilders favor sarcoplasmic hypertrophy which increases muscle size but it's generally viewed as form over function.

Functional hypertrophy, also termed myofibrillar hypertrophy, leads to a growth of active contractile tissue, which means the muscle tissue is growing.

You might think that someone training for size would only need sarcoplasmic, whereas someone training for strength would only need myofibrillar.

This post / discussion is incomplete in many ways; only one is that it fails to explain / account for the difference between myofibrillar growth vs sarcoplasmic growth and the type of training that accounts for each adaption.

The argument goes that because sarcoplasmic hypertrophy isn't contractile, it is somehow an impediment to performance and that as rugby players we should only seek myofibrillar hypertrophy.
