Final answer:
The acronyms FTP, TCP, HTTP, and IP are internet protocols and are not related to load training in program design for resistance training.
Step-by-step explanation:
The protocol used during load training in program design for resistance training is not represented by any of the options provided: 1) FTP, 2) TCP, 3) HTTP, 4) IP. These acronyms refer to internet protocols and have no direct correlation with resistance training principles. Load training typically involves determining the proper weight, reps, and sets for strength development, which is based on exercise science principles and not on technological protocols.
