The threatening of homeostasis causes the body to increase its energy transport capacity. When this occurs, the body stores more CP in the muscle cells, which enhances protein metabolism leading to hypertrophy. Theoritically, this is why high volume training/shorter rest intervals (30s-1.5m) are associated with hypertrophy.
The CNS and ATP/CP stores are both used during maximal lifting. I will consider strength training maximal lifting due to the heavier weights associated with this style of training. The CNS takes longer to recover than the skeletal system. Longer rest periods are needed to fully recover the CNS and (ATP/CP system-usually recovered at the 3 minute mark). If these systems are under recovered, nerve impulses from the CNS and the energy needed from the APT/CP system will not be as great. Therefore, leading to less weight lifted. The main goal of strength training is to increase strength. Thats why 2-5 minutes is associated with this style of training.
Hypertrophy and Strength training do correlate with each other. As the muscle hypertrophies, more myosin and actin form, leading to more contractile units. The more contractile units, the greater force. This why it is crucial to incorporate both styles of training into your program. Yes, rep ranges are important also!
