“…In summary, while investigations often report greater hypertrophy of fROM training when compared to pROM at short muscle lengths, 2,4,5,7,13 this superiority disappears when the comparison is made between pROM at longer muscle lengths versus fROM; in some cases, the pROM training at longer muscle lengths is actually more effective than the fROM, at least in certain muscles of the lower limbs. 7 Therefore, it is necessary to consider the joint angle in which the pROM is performed-that is, at a shorter or longer muscle length-when comparing changes in muscle size. Importantly, the hypertrophic effects of training throughout various ROM configurations may vary based on the given exercise, muscle, and site of hypertrophy assessment; these considerations warrant further investigation.…”
