Design of a nintervention protocol fo rtime-efficient strength training using alternating sets

The aim of this research is to design a detailed velocity-based training (VBT) protocol to comparethe training effects between traditional sets (TS) and alternating sets (AS). This is a methodological study describing the intervention protocol for application in experimental studies.It is proposed the participation of 40 to 50 strength-trained subjects randomly assigned to twoexperimental groups (TS and AS) and a control group. Sixteen VBT sessions will be completedover 8 weeks, with two sessions per week (72-96 h apart). Each session will include squat (SQ),bench press (BP) and prone bench press (PBP) exercises performed on a Smith machine in the same sequence. All training variables - including relative loads (%1RM), intra-set velocity loss,number of sets, rest between sets and frequency of sessions - will remain constant. After a familiarisation period, participants will undergo pre- and post-intervention testing, includingprogressive load testing
